[0020] (Energy conversion device) Hereinafter, an energy conversion device according to one embodiment of the present invention will be described with reference to the drawings. As shown in Figure 1, the energy conversion device 1 comprises a liquid tank 11, a gas receiving section 12, a nozzle 13, a gas cylinder 14, an output means 3, and a recovery device 4. This energy conversion device 1 is a device that injects compressed gas as a primary energy source into a liquid tank 11 in which liquid 10 is stored, and converts the buoyant energy generated into secondary energy that can be output from the liquid tank 11.

[0021] The liquid tank 11 is a sealable tank and is normally used in a sealed state. Liquid 10 is stored in the liquid tank 11. Liquid 10 is preferably water, for example, but is not limited to water and any liquid can be used. The size of the liquid tank 1 is, for example, 2 to 3 m, but is not limited to this. Inside the liquid tank 11 is a power mechanism 31 that generates rotational motion using the buoyancy of the liquid 10. The power mechanism 31 comprises a belt 31a arranged in a vertically elongated ring shape, two upper and lower gears 31b on which the belt 31a is stretched, and a gear 31b that rotates as the belt 31a moves. In Figure 1, the upper gear 31b is submerged in the liquid 10, but its upper part may be above the liquid surface, for example, nearly the upper half of the gear 31b may be above the liquid surface. The amount to release should be determined appropriately by considering factors such as the effectiveness of the buoyancy provided by the gas in the gas receiving section 12 and the resistance to the rotation of the gear 31b, for example, the resistance exerted by the liquid 10 on the gas receiving section 12.

[0022] Multiple gas receiving units 12 are provided vertically within the liquid tank 11 by being distributed in a ring shape on the belt 31a. The gas receiving units 12 can move up and down in conjunction with the movement of the belt 31a, and rotate at the upper and lower positions, performing a circumferential motion between the upper and lower parts as a whole. In this embodiment shown in Figure 1, the belt 31a and the gear 31b rotate clockwise.

[0023] The nozzle 13 ejects compressed gas from below the gas receiving section 12 located at the bottom of the liquid tank 11. The compressed gas is captured by the gas receiving section 12, giving it buoyancy. The gas receiving section 12 receives buoyancy from the liquid 10, but when moving upward, it receives a greater buoyancy than when moving downward due to the compressed gas ejected from the nozzle 13. In Figure 1, only one nozzle 13 is shown, but there may be multiple nozzles. For example, like an upward shower nozzle, multiple openings of the nozzle 13 can be distributed across the entire surface of the downward opening of the gas receiving section 12, allowing gas to be released into the gas receiving section 12 from a wide area.

[0024] As shown in Figures 2(a) and 2(b), the gas receiving section 12 is configured with movable vanes 12a that can be opened and closed. When it receives compressed gas ejected from the nozzle 13 and generates buoyancy, it is in an open state, and when it does not receive compressed gas and does not generate buoyancy from the gas, it is in a closed state. This structure allows the circumferential motion of the gas receiving section 12 and the belt 31a to be performed more efficiently.

[0025] The gas cylinder 14 stores compressed gas as a primary energy source and delivers the compressed gas to the nozzle 13. The gas cylinder 14 ejects the compressed gas from the nozzle 13 via a valve 14a that is controlled to open and close. The valve 14a is controlled to open only when the gas receiving section 12 is in a predetermined position. As a result, the compressed gas is efficiently captured in the gas receiving section 12, thus suppressing the consumption of compressed gas, and the mixing of gas bubbles into the liquid 10 is suppressed, allowing the density of the liquid 10 to be maintained at a high level, thus effectively utilizing the liquid 10's inherent buoyancy.

[0026] The gas cylinder 14 is connected to a compressed gas generator 5 that produces compressed gas. The compressed gas generator 5 can be a general-purpose compressor that converts mechanical energy into the energy of a fluid gas by pressurizing the gas through the rotational motion of an impeller or rotor, or the reciprocating motion of a piston. The compressed gas generator 5 is powered by a power source 50. The power source 50 can preferably be a natural energy source, such as wind power, geothermal energy, hydropower, tidal power, or wave power, in order to suppress greenhouse gas emissions.

[0027] The compressed gas produced by the compressed gas generator 5 is a gas whose pressure has been increased so that it can be supplied from the nozzle 13 to the gas receiving section 12 against the water pressure of the liquid 10 in the tank 11. The gas supplied to the gas receiving section 12 is supplied to provide buoyancy to the gas receiving section 12 due to the liquid 10.

[0028] Output means 3 is a means for outputting the kinetic energy of upward movement due to buoyancy generated in the gas receiving section 12 as secondary energy to the outside of the liquid tank 11. In this embodiment shown in Figure 1, output means 3 includes a power mechanism 31 that converts the kinetic energy due to buoyancy into rotational energy of the rotating shaft 31c of the gear 31b, and a power generation device 32 that converts the rotational energy of the rotating shaft 31c into electrical energy as secondary energy.

[0029] The recovery device 4 is a device that returns gas from the liquid tank 11 to the gas cylinder 14. The space above the liquid tank 11 is a gas chamber 15 where gas accumulates. The recovery device 4 sends the gas accumulated in the gas chamber 15 to the gas cylinder 14 via the compressed gas generator 5. The gas in the gas chamber 15 consists of gas created from the nozzle 13 and vapor from the liquid 10.

[0030] The recovery device 4 includes a three-way valve 41, a sub-pumper 40, and a valve 42 along the pipeline from the gas chamber 15 to the compressed gas generator 5. The three-way valve 41 and the valve 42 are flow control and shut-off valves that are controlled to open and close. It is preferable that these be composite valves that also function as check valves. The three-way valve 41 functions as a valve that releases gas to reduce the pressure in the gas chamber 15. The sub-pumper 40 functions as a buffer that supplements the capacity of the gas chamber 15.

[0031] Furthermore, if the compressed gas generator 5 has the functions of a three-way valve 41, a sub-pumper 40, and a valve 42, the recovery device 4 may consist only of piping connecting the gas chamber 15 and the compressed gas generator 5.

[0032] Next, the operation of the energy conversion device 1 will be explained. While the operating gas, or compressed gas, of this device will be assumed to be air, it is not limited to air. Furthermore, the liquid 10 will be assumed to be water. Water is injected into the liquid tank 11 where the power mechanism 31 is installed, piping such as the gas cylinder 14 is connected to the nozzle 13, and the piping of the recovery device 4 is connected to the gas chamber 15. The compressed gas generator 5 is then operated to prepare the compressed gas. The gas pressure in the gas chamber 15 is adjusted using the three-way valve 41, and the compressed gas is further supplied to the nozzle 13 while adjusting the valve 14a.

[0033] The compressed gas that emerges from the upward-facing opening of the nozzle 13 is captured by the gas receiving section 12, which opens at the bottom of the upward-moving belt 31a, and replaces the water in the space above the gas receiving section 12. As a result, buoyancy due to the gas is applied to the gas receiving section 12, a difference is created in the force acting on the left and right belts 31a due to the buoyancy of the liquid 10, causing the belts 31a to gradually begin to rotate clockwise. As gas is received by the gas receiving sections 12 that move one after another above the nozzle 13, the circumferential movement of the belts 31a reaches a steady state.

[0034] In the steady state of the belt 31a's rotational movement, gas is released from the gas receiving section 12, which rotates with the belt 31a in contact with the upper gear 31b. The gas receiving section 12, having released the gas, moves downward with its movable vanes 12a closed. When the gas receiving section 12, which rotates with the belt 31a in contact with the lower gear 31b, comes above the nozzle 13, its movable vanes 12a open, and it receives gas from the nozzle 13.

[0035] The circling belt 31a converts the kinetic energy from the gas receiving section 12, which rises due to buoyancy, into rotational kinetic energy for the gear 31b. The rotation of the gear 31b rotates the rotating shaft 31c, and this rotational energy is converted into electrical energy generated by the power generator 31 and taken out externally. Of course, this energy can also be used to directly move gears or other components, such as turning a ship's propeller.

[0036] Here, we will explain the relationship between the three pressures P1, PW, and P2. Pressure P1 is the pressure of the compressed gas delivered from the gas cylinder 14. Pressure PW is the water pressure determined by the depth of the liquid 10. Pressure P2 is the gas pressure in the gas chamber 15. These pressures are related by the following equation when the energy conversion device 1 is operating in a steady state. This equation shows the conditions under which the gas from the gas cylinder 14 can enter the liquid 10 through the nozzle 13. P2+PW <P1 However, when releasing gas into a liquid, it is possible to move the gas into a space where weight is added by water, even at extremely low pressure, by making the diameter of the release pipe extremely small to create microbubbles, or by installing multiple pipes through which the gas passes. Alternatively, if liquid butane is released from the end of a pipe and the water pressure in the tank is only sufficient to cause the butane to turn into a gas, it will vaporize efficiently.

[0037] The compressed gas generator 5 compresses the gas to obtain the required pressure P1, making it at a high pressure of at least the water pressure PW. The recovery device 4 controls the opening and closing of the three-way valve 41 to adjust the gas pressure P2 in the gas chamber 15 so that the above equation is satisfied.

[0038] In this energy conversion device 1, compressed gas circulates within the device as the working gas, subject to pressure fluctuations. In a steady state, the energy conversion device 1 forms a closed circulation circuit for the working gas. Various valves, pressure sensors, tanks, and other components may be appropriately incorporated into the energy conversion device 1 to adjust the pressure of the working gas.

[0039] With this energy conversion device 1, compressed gas is injected as a primary energy source into a liquid tank 11 where liquid 10 is stored, the buoyant energy generated is converted into secondary energy, and the gas can be recovered from the liquid tank 11 into a gas cylinder 14 for reuse. Therefore, energy can be generated and converted efficiently. Gas reuse is possible when a special gas, rather than air, is used as the working gas, i.e., compressed gas, and that special gas can be recovered and reused. Also, since the gas in the gas chamber 15 is not released into, for example, the atmosphere, the pressure P2 of the gas in the gas chamber 15, i.e., the pressure energy of the gas, can be reused.

[0040] Next, another embodiment will be described with reference to Figure 3. In this embodiment, the energy conversion device 1 is equipped with a transmission mechanism 30 that mechanically extracts the rotational energy of the gear 31b to the outside, instead of the power generation device 32 in the embodiment of Figure 1. In this example, the liquid tank 11 is installed underground, but it is not limited to being installed underground; it may be grounded in a semi-underground location or above ground. The same applies to the energy conversion device 1 in Figure 1.

[0041] The transmission mechanism 30 includes a coupling device 3a, such as a gear, which engages with the lower gear 31b of the power mechanism 31 to receive its rotational energy, and a shaft 3b, a coupling device 3c, a shaft 3d, a coupling device 3e, and a shaft 3f, which are sequentially coupled to the coupling device 3a.

[0042] The horizontal shaft 3b is led out of the liquid tank 11 through a communication opening 11w provided in the side wall of the liquid tank 11, which is located to the side of the lower gear 31b. A water seal tank 11A is also provided on the side outside the liquid tank 11, surrounding the coupler 3c and the vertical shaft 3d. The water seal tank 11A has a communication opening 11w that communicates with the inside of the liquid tank 11 and an upper opening 11k that opens upward. The water seal tank 11A contains liquid 10, and its liquid level is exposed to atmospheric pressure through the upper opening 11k. The relative liquid levels of the liquid 10 in the liquid tank 11 and the liquid 10 in the water seal tank 11A will be different when the gas pressure P2 in the gas chamber 15 is not atmospheric pressure.

[0043] The output mechanism 30 of the output means 3 in this energy conversion device 1 uses a water seal structure, so that mechanical energy can be extracted to the outside of the energy conversion device 1 without using a strict sealing structure. The water seal structure can also be applied to the upper gear 31b in the same way.

[0044] The transmission device 30 extracts the energy converted and generated in the liquid tank 11 as mechanical energy via these couplers 3a, 3c, 3e and shafts 3b, 3d, 3f, and transmits it to the external operating device 33.

[0045] The operating device 33 is a water pump and is configured with multiple buckets 33d attached to a chain 33c that is stretched over upper and lower sprockets 33a and 33b. The rotational energy extracted to the outside of the energy conversion device 1 is transmitted as rotational energy to the upper sprocket 33a via the shaft 3f.

[0046] This energy conversion device 1 can convert the energy based on the pressure of compressed gas into mechanical energy and output it, so that mechanical energy can be used directly as the energy for the mechanical operation of the operating device 33.

[0047] Next, with reference to Figures 4, 5, and 6, examples of combinations when multiple liquid tanks 11 are used will be described. Multiple liquid tanks 11 may be provided in parallel or in series with respect to the gas cylinder 14. The energy conversion device 1 shown in Figure 4 shows an example in which three liquid tanks 11 of the same structure are installed in parallel with respect to the gas cylinder 14. Compressed gas is delivered to the nozzle 13 of each liquid tank 11 via a valve 14. The gas in the gas chamber 15 of each liquid tank 11 is recovered into a sub-cylinder 40 via a three-way valve 41. The liquid tanks 11 arranged in parallel are not limited to having the same structure, but may have different structures, and the number is not limited to three.

[0048] The energy conversion device 1 shown in Figure 5 illustrates an example in which three liquid tanks 11, each with the same structure, are installed in series with respect to a gas cylinder 14. Each liquid tank 11 is positioned at the same horizontal level. Compressed gas is supplied to the nozzle 13 of the first liquid tank 11 via a valve 14a, starting from the side closest to the gas cylinder 14. Gas is supplied from the gas chamber 15 of the first liquid tank 11 to the nozzle 13 of the second liquid tank 11 via a three-way valve 41. Gas is supplied from the gas chamber 15 of the second liquid tank 11 to the nozzle 13 of the third liquid tank 11 via a three-way valve 41. Finally, the gas from the gas chamber 15 of the third liquid tank 11 is recovered into a sub-cylinder 40.

[0049] Valve 14a and the three three-way valves 41 are used to adjust the pressures corresponding to the aforementioned pressures P1, PW, and P2 in the three liquid tanks 11. The liquid tanks 11 arranged in series are not limited to having the same structure, but may have different structures, and the number is not limited to three.

[0050] The energy conversion device 1 shown in Figure 6 illustrates an example in which two liquid tanks 11, each with the same structure, are installed in series, one above the other, relative to a gas cylinder 14. Gas from the gas chamber 15 of the lower liquid tank 11 is sent to the nozzle 13 of the upper liquid tank 11 via a three-way valve 41. The piping leading to the gas extends to the upper level of the upper liquid tank 11, then is drawn back down to below the liquid tank 11 and connected to the nozzle 13. This piping structure is designed to prevent the liquid 10 from the upper liquid tank from flowing into the lower liquid tank 11 through the gas piping.

[0051] Furthermore, the upper and lower liquid tanks 11 are connected to each other by a water seal tank 11A. In this embodiment, a configuration is realized in which mechanical energy is extracted from each of the upper and lower liquid tanks 11 via a common water seal tank 11A and a transmission mechanism 30. Moreover, the upper and lower liquid tanks 11 are not limited to being connected to each other by a water seal tank 11A; the upper and lower liquid tanks 11 may be independent of each other. For example, the set of liquid tank 11, water seal tank 11A and transmission mechanism 30 shown in Figure 3 may be arranged in series vertically, in which case the upper and lower liquid tanks 11 each have their own water seal tank 11A and transmission mechanism 30.

[0052] Next, an example of a compressed gas generator 5 will be described with reference to Figures 7(a) and 7(b). This compressed gas generator 5 generates compressed gas by pressurizing gas using a pressurizing piston 52 provided inside a cylinder 51. The pressurizing piston 52 comprises a piston body 52a and a sealing material 52b consisting of a float-shaped O-ring that can adjust the internal pressure.

[0053] A pipe for generating compressed gas is connected to the lower side wall of cylinder 51. This pipe is connected to a gas cylinder 14 via a three-way valve 51a. The lower part of cylinder 51 is connected to a water seal tank 11A located outside the side wall of cylinder 51 by a water seal structure. A chain is attached to the lower surface of the pressurizing piston 52, and this chain is fixed through the water seal structure to a hoisting machine 53 located above the water seal tank 11A, allowing it to be freely wound up and unwound.

[0054] In the pressurization process, as shown in Figure 7(a), the internal pressure of the ring-shaped sealing material 52b is increased to create a slidable sealing structure between the pressurizing piston 52 and the inner wall of the cylinder 51. Next, the pressurizing piston 52 is moved downward by the hoisting machine 53 to compress the gas inside the cylinder 51, and the compressed gas is sent to the gas cylinder 14.

[0055] In the intake process, as shown in Figure 7(b), the internal pressure of the float-shaped sealing material 52b is reduced to create a gap between the pressurizing piston 52 and the inner wall of the cylinder 51. Next, the hoisting machine 53 is loosened to pull the pressurizing piston 52 upward and draw gas into the cylinder 51.

[0056] The mechanism and energy required to compress the gas by pushing the pressurizing piston 52 downwards are not limited to those using a hoisting machine 53, and various methods can be used. For example, instead of a water seal structure and a hoisting machine 53, a configuration that applies hydraulic or water pressure to the upper surface of the pressurizing piston 52 may be used. The intake process can be easily performed by lowering the internal pressure of a float-shaped sealing material 52b whose internal pressure can be adjusted.

[0057] Next, with reference to Figure 8, another example of the compressed gas generator 5 will be described. This compressed gas generator 5 generates the compressed gas by heating solid dry ice to a gaseous state using the heat of combustion of a mixed gas containing hydrogen and oxygen, thereby expanding its volume. The generated compressed gas is discharged from the gas cylinder 14. In general, the working gas can be any gas that generates buoyancy when discharged from the nozzle 13. For example, it may be in a liquid or solid state rather than a gas between the gas chamber 15 and the gas cylinder 14. In the recovery device 4 and beyond, the working gas can be dry ice or a liquefied gas that is converted into a solid or liquid. For example, a substance that is compressed into a liquefied gas may be used as the working gas.

[0058] Next, with reference to Figure 9, another example of the energy conversion device 1 will be described. In this energy conversion device 1, the compressed gas generator 5 generates compressed gas by heating the gas through a gas pipe to a heat exchanger 54, and otherwise it is the same as the energy conversion device 1 in Figures 1 and 3. Upstream of the heat exchanger 54, that is, on the sub-cylinder 40 side, there is a valve 42 that functions as a check valve. Also, downstream of the heat exchanger 54, that is, on the gas cylinder 14 side, a three-way valve 51a for gas pressure adjustment and the like is provided as needed.

[0059] This compressed gas generator 5 has a heat transfer medium 54a that becomes hot sealed inside the housing of a heat exchanger 54. The piping that guides the working gas, that is, the compressed gas, which circulates within the energy conversion device 1 and operates the energy conversion device 1, is surrounded by the heat transfer medium 54a within the heat exchanger 54. The working gas inside the piping receives heat from the heat transfer medium 54a, is pressurized, and becomes compressed gas. The working gas does not necessarily have to be in a gaseous state while circulating within the energy conversion device 1; it may be in a liquid or solid state. When referring collectively to working gas in states other than gas, it is called working gas material.

[0060] The heat exchanger 54 may, for example, in an embodiment of a solar water heater, contain metallic sodium as a heat transfer medium 54a with a high boiling point. The heat exchanger 54 may heat the heat transfer medium 54a using natural energy. Natural energy may include, for example, solar energy, geothermal energy (such as the heat of magma), or the heat of a hot spring.

[0061] Furthermore, the substance used as the working gas may be arbitrarily selected and used depending on its combination with the liquid 10 in the liquid tank 11, and also depending on the operating conditions of the energy conversion device 1, such as various pressures P1, PW, P2, the temperature conditions of the liquid 10, and its physical properties during operation. For example, a refrigerant such as Freon may be used as the working gas. In addition, as the liquid 10, ammonia water or the like may be used instead of water.

[0062] Next, with reference to Figure 10, the circulation process of the working gas in one embodiment of the energy conversion device 1 will be schematically described. In the energy conversion device 1 of this embodiment, the working gas is compressed into a high-pressure gas by the compressed gas generator 5, sent to the main body 11R of the energy conversion device via the gas cylinder 14, recovered from the main body 11R to the sub-cylinder 40, and returned to the compressed gas generator 5. The main body 11R is a general term for the liquid tank 11 and the entire structure inside it, and includes components for converting the primary energy from the compressed gas into kinetic energy and outputting it as secondary energy to the outside of the liquid tank 11.

[0063] The compressed gas generator 5 of this embodiment includes a compressor 16, a heat exchanger 17, and a vaporizer 18. Here, we will assume that the working gas is a fluorocarbon (CFC), which is used as a refrigerant in refrigerators and the like. When such a working gas is heated to a high temperature, it can be used as a heat source; when it expands and releases heat of vaporization and is cooled, it can be used as a heat-retaining material; and when it is made into a high-pressure gas, it can also be used as a gas that provides buoyancy to the gas receiving section 12 in the energy conversion device 1.

[0064] The compressor 16 compresses the working gas to a high temperature and high pressure state, for example, using electrical energy. The heat exchanger 17 releases the heat from the working gas inside itself to heat a liquid or gas such as water or air. The heated liquid or gas is then guided to another location and used for heating in air conditioning systems, etc.

[0065] The vaporizer 18 expands the working gas through an expansion valve and other means, further lowering its temperature. The lowered working gas can absorb heat from its surroundings, and this heat absorption capacity is used in the construction of cooling systems. After passing through the heat exchanger 17 and the vaporizer 18, the working gas becomes a compressed gas with appropriate pressure adjustment, which is then sent to the main unit 11R via the gas cylinder 14 for energy conversion.

[0066] This circulation process allows the compressor 16 to pre-inject excess energy into the working gas, and then the subsequent heat exchanger 17 and vaporizer 18 to use that excess energy for heating and cooling, respectively, before performing energy conversion using buoyancy. In an environment where excess energy can be injected, a unified system can be constructed as a whole.

[0067] Next, another embodiment of the energy conversion device 1 will be described with reference to Figure 11. In this embodiment of the energy conversion device 1, the power mechanism 31 in the energy conversion device 1 of Figure 1 is replaced with a power mechanism 31A having the characteristics of a water turbine. The power mechanism 31A has a plurality of gas receiving parts 12 arranged around the outer circumference of a rotating body that rotates around a single axis. The gas receiving parts 12 have the structure shown in Figures 2(a) and 2(b).

[0068] In this embodiment, two clockwise rotating power mechanisms 31A are installed inside the liquid tank 11. Each power mechanism 31A is also equipped with a valve 14a and a nozzle 13. The rotational energy of the power mechanisms 31A is converted into electrical energy by a power generator 32.

[0069] (Vehicle movement device) Next, with reference to the drawings, a vehicle body moving device according to one embodiment of the present invention will be described. As shown in Figures 12(a) and 12(b), the vehicle body moving device 2 comprises a vehicle body 21, sleds 22 for sliding on ice provided on the front, rear, left, and right sides of the underside of the vehicle body 21, a pair of left and right rails 23 provided on the road surface 20, on which a liquid has been frozen to form an ice surface 2a that guides the sleds 22 to slide on the ice, and a drive device for moving the vehicle body 21.

[0070] The rail 23 comprises a housing 23a fixed to the road surface 20 and having a concave cross-section with grooves formed in the longitudinal direction, and a refrigerant pipe 23b that carries refrigerant and is located inside the grooves. Water is placed in the grooves of the housing 23a and cooled by the refrigerant pipe 23b to form ice 2b. The surface of this ice 2b becomes the ice surface 2a when the sled 22 slides on the ice. The rail 23 may be equipped with a cover to prevent rain from entering the interior when the sled 22 is not sliding on the ice, and may also be provided with a drain hole to discharge water present on the ice surface 2a. This cover and the housing 23a of the rail 23 are cooled by circulating water from an underground tank through pipes.

[0071] Guide wheels 21a are provided close to the outer surface of the rail 23. The guide wheels 21a guide the vehicle body 21 so that it runs along the rail 23. Such a guiding device may be provided between the skid 22 and the rail 23. For example, to prevent the skid 22 from deviating from the rail 23, a structure on the rail 23 may be configured to enclose and surround the skid 22.

[0072] The drive system consists of wheels 24 powered by an engine or motor mounted on the vehicle body 21. The wheels 24 are configured to be able to move up and down relative to the vehicle body 21. When not being driven, they move upward away from the road surface 20, and the vehicle body 21 travels on the ice surface 2a by skidding 22 (Figure 12). When driven, the wheels 24 make contact with the road surface 20, causing the vehicle body 21 to travel on wheels (Figure 13).

[0073] As shown in Figure 13(a), the wheels 24 may be arranged in pairs in the front-to-back direction between the front and rear sleds 22, or as shown in Figure 13(b), there may be only one wheel in the front-to-back direction. The arrangement and number of wheels 24 can be arbitrarily set according to the respective roles of sled driving and wheel driving. For example, when the vehicle is driven by the wheels 24 with the sled 22 in contact with the ice surface 2a, the weight of the vehicle body 21 is supported by the sled 22, so the wheels 24 only need to drive the vehicle, and one wheel in total is sufficient. On the other hand, when the weight of the vehicle body 21 is supported by the wheels 24, at least three wheels 24 are required to provide three-point support.

[0074] The vehicle body moving device 2 may be an embodiment that moves the vehicle body 21 using a drive device that does not have wheels 24. For example, a jet propulsion system or a propeller propulsion system may be mounted on the vehicle body 21 as the drive device. Alternatively, a linear motor may be used as the drive device. In this case, the track that forms the magnetic field of the linear motor may be covered with a liquid to form an ice surface. Alternatively, a linear motor and wheels 24 that obtain driving force from an engine or motor mounted on the vehicle body 21 may be combined to form a drive device.

[0075] Referring to Figures 14(a) and 14(b), a braking device according to one embodiment of the vehicle movement device 2 will be described. The vehicle body 21, which is sliding on the ice on the rail 23 using the sled 22, is decelerated or stopped by the absorption of its kinetic energy by the braking device. The vehicle movement device 2 can be equipped with any braking device. The braking device 25 in this embodiment absorbs kinetic energy by the fluid's resistance to movement. The braking device 25 is an application of a device generally called a shock absorber or damper.

[0076] The braking device 25 is provided along the rail 23 and includes, for example, a cylinder 25a filled with liquid, a piston 25b that moves relative to the cylinder 25a to move the liquid inside, a locking portion 26c provided on the piston 25b, and an engaging portion 21b provided on the lower part of the vehicle body 21 that engages with the locking portion 26c. The cylinder 25a and piston 25b have the structure and function of a shock absorber. The pairs of cylinder 25a and piston 25b are arranged at predetermined intervals along the rail 23. The pairs of cylinder 25a and piston 25b may be arranged at predetermined intervals along the entire length of the rail 23, or they may be arranged at predetermined intervals within a predetermined range.

[0077] The engaging portion 21b is movable vertically and, during braking, is lowered from the moving vehicle body 21 and engages with the locking portion 26c, pushing the locking portion 26c in the direction of travel (left in the figure). As a result, the piston 25b is pushed to the left and moves, and the kinetic energy is converted and absorbed into thermal energy by the viscous resistance of the oil, causing the vehicle body 21 to decelerate.

[0078] The braking device 25 is equipped with multiple safety valves 25d to release pressure inside the cylinder 25a to prevent damage. These safety valves 25d are set to function in stages according to the pressure level. If the vehicle body 21 cannot be stopped within the range of motion of the piston 25, the locking between the locking portion 26c and the engaging portion 21b is automatically released, and the engaging portion 21b locks with the locking portion 26c of the next cylinder 25a and piston 25b pair in the direction of travel, and braking action is performed by that pair. The braking device 25 is set and arranged according to predetermined rules between travel speed and braking distance.

[0079] (Energy utilization device) Next, with reference to Figure 15, an energy utilization device 6 according to one embodiment of the present invention will be described. The energy utilization device 6 is a device that utilizes the energy of groundwater at a constant temperature. The energy utilization device 6 comprises an underground tank T, a structure 60, pipes 62 and a circulation pump P3, and a fan 63.

[0080] The underground tank T is buried in a predetermined underground location where groundwater of a predetermined constant temperature can be obtained, and stores groundwater of that constant temperature. The underground tank T is located, for example, near a groundwater layer L containing groundwater of a constant temperature, together with a pump P1, and stores the groundwater pumped up by the pump P1. The groundwater is then pumped from the underground tank T to the surface by a pump P2.

[0081] The structure 60 has a cavity 61 inside, formed by connecting multiple hollow tubes 6a made of a light-transmitting material. The cavity 61 is used as an air conditioning space or an energy exchange equipment installation space. The structure 60 may be installed above ground when used in the presence of sunlight, for example, and underground in other cases. When installed underground, it is easier to use under a predetermined constant temperature. The structure 60 is used as a sealed space by sealing both ends with walls formed by connecting the hollow tubes 6a. The structure 60 may also be used as an open space with parts of both ends open.

[0082] Pipe 62 and circulation pump P3 are used to circulate constant-temperature groundwater stored in the underground tank T and pumped up by pump p2 through the hollow tube 6a of the structure 60. The required amount of groundwater is stored in the auxiliary tank T1, circulated through the hollow tube 6a, and then returned to the underground tank T. This circulation within the hollow tube 6a maintains a constant temperature inside the cavity 61. Fan 63 creates airflow in the sealed cavity 61 formed by the structure 60. This airflow prevents stagnant air from forming inside the cavity 61. The structure 60 may also be equipped with external piping from one end to the other to form a closed air passage, and fan 63 may be used to create a unidirectional airflow within the structure 60.

[0083] As shown in Figure 16, the cavity 61 is suitably used as an installation space for a solar panel 64. The solar panel 64 is an energy exchange device that converts solar energy into electrical energy. The solar panel 64 is located in the cavity 61, which is maintained at groundwater temperature on all four sides, and is ventilated by a fan 63, so that the panel surface can be kept at a low temperature and power generation efficiency can be maintained. The structure 60 can be made into an appropriate shape that optimizes and improves the temperature control of the contents housed within the cavity 61. For example, in the case of the solar panel 64 in Figure 16, the cavity 61 may be sealed by surrounding it with a wall formed of a hollow tube 6a close to the outer circumferential surface including the front and back surfaces of the panel, so that the panel can be housed in the smallest possible space, or it may be an unsealed cavity 61 with a part of it open.

[0084] Next, an example of the application of the energy utilization device 6 will be explained with reference to Figure 17. This energy utilization device 6 has multiple underground tanks T (three in the illustrated example) and a mixer 6mx that mixes groundwater from each tank. The underground tanks T are individually buried at multiple depths underground so that groundwater with different temperatures t1, t2, and t3 can be obtained from each other. The mixer 6mx mixes the groundwater with different temperatures t1, t2, and t3 obtained from these multiple underground tanks T, thereby supplying groundwater at a constant temperature t0 regardless of the season. Even if there are seasonal fluctuations in the temperature of each groundwater, the predetermined temperature can be maintained by changing the mixing ratio considering the temperature difference between each groundwater.

[0085] Next, with reference to Figure 18, an energy utilization device 6A according to another embodiment of the present invention will be described. The energy utilization device 6A is a device that utilizes the energy of the constant temperature underground and comprises a hollow pipe 65 that reciprocates between the underground at a predetermined depth, which has a predetermined constant temperature, and the surface, and a fan 66 that sends air from the surface side into the hollow pipe 65. The air sent into the hollow pipe 65 by the fan 66 undergoes heat exchange through heat release or absorption in the underground at the predetermined depth, and the cooled or heated air can be used for air conditioning on the surface side. In order to facilitate heat exchange underground, the surface area of ​​the piping may be increased by providing a large number of fins on the piping or by using a large number of branched piping at the heat exchange location. While it varies depending on the latitude, in Honshu, Japan, the ground temperature at a depth of 5 meters underground remains at approximately 15 degrees Celsius throughout the year. This property can be utilized by, for example, installing tanks at a depth of around 5 meters underground to store water, and then transferring the cool temperature (in summer) or warm temperature (in winter) to a target location on the surface using pipes, etc. This could then be used to construct a system similar to one made by connecting plastic bottles. It can also be used to flow through structures. By creating space around the path through which the liquid flows, the temperature of the air in that space will approach that of the surrounding liquid. The space path can be made long and narrow to allow for efficient heat exchange. (Figure R1)

[0086] Next, with reference to Figure 19, an energy utilization device 6B according to yet another embodiment of the present invention will be described. The energy utilization device 6B is a device that utilizes sunlight energy and comprises a structure 60 formed by connecting a plurality of hollow tubes 6a made of a light-transmitting material to form a cavity 61 inside, a pipe 62 and a circulation pump P3 for circulating water or hot water through the hollow tubes 6a of the structure, and a fan 63 for blowing air from one opening to the other in the cavity 61 formed by the structure 60.

[0087] The structure 60 is installed in a location that can receive sunlight, and seawater 9 is passed through the bottom surface of the cavity 61 in a plan view, with air from the fan 63 passing over the top surface of the seawater 9. This promotes the evaporation of the seawater 9, and salt can be obtained.

[0088] Next, with reference to Figure 20, an energy utilization device 6C according to yet another embodiment of the present invention will be described. The energy utilization device 6C is an energy utilization device 6C that utilizes compressed air for air conditioning, and comprises an air compressor 68 powered by natural energy, and a tank Ta buried underground for storing the air compressed by the air compressor 68. In this example, solar light is used as the natural energy source, so a solar panel 64 is provided.

[0089] Compressed air stored in tank Ta and temperature-controlled to a predetermined temperature can be supplied through pipes to the air-conditioned space 67 for use.

[0090] Next, with reference to Figure 21, an energy utilization device 7 according to yet another embodiment of the present invention will be described. The energy utilization device 7 is an energy utilization device 7 that generates electricity using natural energy and comprises a wall structure 71 installed on the coast that simulates a ria coast where the force of ocean waves causes seawater to rise to a position higher than the sea surface, a tank 72 that introduces and stores the seawater 70 that has risen up by the wall structure 71, and a hydroelectric generator 74 that generates electricity using the potential energy of the seawater 70 stored in the tank 72.

[0091] The waves of seawater crashing onto the shore have their paths narrowed by the funnel-shaped wall structure 71, rush up the slope, and the seawater 70 flows into the tank 72. Once the seawater in the tank 72 begins to flow toward the hydroelectric generator 74 via pipes 73a, 73b and pump 73, the flow downstream is sustained without further pumping.

[0092] By replacing the hydroelectric generator 74 with an air compressor, instead of generating electricity, the potential energy can be used to produce compressed air and stored in a tank, thereby saving the potential energy as pressure energy.

[0093] A substance that vaporizes under pressure changes, such as dry ice, is placed in an airtight container, and a fluid liquid is added inside. The energy of the gas, which moves upward on the ground due to the difference in specific gravity, is used to move a vane or similar mechanism set inside the airtight container. The vane converts the energy into rotational energy, which is then extracted to the outside via gears or shafts and used as power. This utilizes a change in the state of matter. The vaporized dry ice (this is just one example; any substance with similar properties can be used) is then guided back into another similar tank through a sealed tank. A valve that can be opened and closed can be installed in part of the sealed tank to adjust the internal pressure. Multiple sealed tanks can be connected. However, if too many are connected, the pressure of the dry ice may not decrease, and it may not vaporize. The vaporized dry ice is finally collected from the end of the tank via a pipe or similar mechanism. This is then repressurized and sent back into the original tank as dry ice, vaporized, or liquid material. In this process, the solid state is easier to send into the sealed tank because it has a smaller volume per unit mass. A pressurizing device is installed to convert dry ice (which is in a vaporized state) back into a solid or liquid state. This device is sealed so that the work can be done without releasing the dry ice or other gases to the outside. Therefore, the dry ice does not leak out to the outside (to the atmosphere, etc.). Energy can be obtained by connecting such devices and assembling such a device. To pump dry ice in a solid or liquid state, it is easiest to imagine it in the same way as a bicycle pump. This is just one example. Imagine pumping air into a bicycle tire; connect the tire to the pump, pack dry ice (solid, liquid, or gas) in a sealed state into the pump, pump it into the tire, and then pump the dry ice (gas, etc.) back into the pump. In reality, when returning the dry ice (gas, etc.) to the pump, it is temporarily pooled in a sealed state using a pressurizing device, and then gradually returned to the pump (the part equivalent to a sealed container) while adjusting the pressure. Pressure sensors can be installed as needed.If dry ice or similar substances are in a solid or liquid state under pressure, they won't suddenly disperse when exposed to the atmosphere, so you don't need to worry too much about it; you can put them into an air pump (equivalent to an airtight container) with only a slight loss. When a lighter substance (such as a gas) is combined with a heavier substance (such as a liquid) and placed in a specific location, the difference in mass causes the two substances to move in a particular direction. That energy can also be extracted and used as an energy source to power other machines or devices. Prepare a light substance (for example, carbon dioxide as a gas) and a heavy substance (for example, water) and place them inside a sealed tank. The water can be pre-filled into the tank from the outside through a pipe. The pipe has an opening and closing valve so that the water in the tank does not leak out when the valve is closed. Then, dry ice (solid carbon dioxide) is moved into the sealed tank from a separate, sealed space without coming into contact with the outside air, through another pipe. Once inside the tank, the pressure decreases and it vaporizes, and the gas moves to the top of the tank. The gas that has moved to the top moves through pipes to a second tank with a similar structure. From there, it moves through the tank and goes to the top again. There are pipes at the top of the tanks, and the carbon dioxide is guided to a specific location through them. The pipes are then connected to a compressor, and the delivered carbon dioxide is converted back into a solid or liquid state. This can then be reinjected as fuel through the inlet of the first tank. Naturally, it's possible to install openings and closing ports, as well as various monitoring devices, to measure and adjust the pressure inside the tank, and monitor them using a computer or similar device. If three sealed tanks are prepared, solid carbon dioxide (which can be injected as dry ice, liquid carbon dioxide, or gaseous carbon dioxide) can be injected into the inlet of the first tank, and the vaporized carbon dioxide can be recovered from the third tank, repressurized, and returned to the inlet of the first tank. The key point is that, for example, when dry ice (or anything with similar properties) vaporizes and moves through water, the energy obtained when that vapor is captured and extracted as energy is different from the energy used to convert carbon dioxide or other substances from gas to solid, or even just to return them to the tank under a certain pressure, because the energy from gravity is not included in this calculation. The same effect occurs even when gravity is simulated. The various substances listed in this document, if they produce similar effects in terms of their properties, will not particularly affect the operating principle. It should be noted that the present invention is not limited to the above configuration and can be modified in various ways. For example, the configurations of each of the above embodiments can be combined with each other. The following is a quote from the basic application on which the priority claim is based. For transporting objects, such as things, replace the wheels of a train with sleds or similar vehicles. Instead of rails, a width just wide enough for a sled to pass through is created, and water or other liquid is placed in this area and cooled using electricity or other means to freeze it, thereby reducing friction and minimizing energy loss. Wheels or other liquids are used to contact the gaps between the rails for acceleration and deceleration. When speed is reached, these wheels or other liquids can be retracted into the vehicle body using electricity or other means to reduce resistance and prevent contact with the ground. The sled portion slides on the frozen surface, but the rail structure has a protruding shape to prevent it from derailing sideways. Tires or other liquids that contact the sides of the rails may be attached to the sled to reduce impact on curves, etc. The route is designed to slope slightly downwards, using gravitational energy to generate acceleration. While it's possible to design the route without elevation changes, the construction costs are calculated, and even if it slopes upwards, the friction is reduced by the skids, allowing the energy of inertia to be used to move the object to higher ground. Even with a slight downward slope, the resistance at the contact points of the vehicle is extremely low, so the vehicle can accelerate rapidly even with only a small amount of energy supplied by the contacting tires. The same applies to linear motor cars and other vehicles that do not make contact with the ground. Furthermore, the generation of air resistance is prevented by creating as much of a vacuum as possible inside the tunnel, such as a tube surrounding the vehicle. Possible methods include opening hatches on the vehicle at stations to create passages to the outside, or installing partitions or doors that open and close vertically within the tunnel, allowing air to be partially introduced at stations to allow passengers to enter and exit. To allow rainwater to drain quickly from structures on lanes where the liquids in contact with the vehicle are kept at a low temperature, a hollow opening should be provided at the end of the lane, allowing the rainwater to flow out through the structure. A roof should be added to the top to prevent rainwater from entering, or the structure should be designed to completely shield the surrounding area. When shielding, a transparent, light-transmitting material or strong plastic can be used, or a structure made by connecting PET bottles (a special type could also be used) can be used. Water can be pumped into the parts of the PET bottles that originally contained juice from an underground tank located about 5 meters underground where the temperature is maintained at around 15 degrees Celsius year-round, using a pump (or, in mountainous areas, the energy of gravity can naturally cause the water to fall). By circulating the water, the temperature of the space through which vehicles travel will approach 15 degrees Celsius, and by adjusting the flow rate of the liquid, air conditioning costs can be reduced. When reducing the pressure of the space through which vehicles travel to reduce air resistance and create a near-vacuum state, the outer perimeter of the space through which vehicles travel can be reinforced with pressure-resistant reinforced plastic or glass. Even when circulating water or other liquids with a pump, water and similar liquids do not suddenly boil when exposed to sunlight or other external factors, so the pump does not need to be operated frequently, resulting in lower energy costs.When energy is obtained from solar panels, etc., solar panels are installed on the roof of the facility or in open spaces such as the sides or lanes. To cool the solar panels, water kept at a constant temperature in an underground circulating tank is flowed over the panels, or a pipe-like structure made of a light-transmitting material is installed nearby, and water at about 15°C from the underground tank is flowed through it to control the temperature of the solar panels. Alternatively, the solar panels are made waterproof and airtight, and placed in a shallow bucket of water, etc., through which water at about 15°C from a depth of about 5 meters underground is flowed and then collected back into the underground tank. If the location allows for natural groundwater to flow, a continuous flow system is also acceptable, and the temperature of the panels can be controlled. Using plastic bottles, for example, the opening is cut off and multiple rectangular cubes are glued together to create a structure in which water from the underground tank is placed. Using a material that transmits light but does not transmit water, such as plastic bottles, a hollow structure can be created inside a water-filled structure. The hollow sections can then be used to place solar panels or other items whose temperature needs to be controlled. This is similar to how solar panels installed in homes can be used to increase power generation, as solar panels reduce power output when they get too hot. Additionally, water at around 15 degrees Celsius from the underground tanks mentioned above can be used to efficiently air-condition the space. Since the ground temperature around the underground tanks varies with depth, multiple tanks can be installed at different depths, and the water from these tanks can be mixed. A structure is created by placing a pipe approximately 5 cm long and wide (this is just a guideline, the scale can be freely changed) inside an underground tank, and installing a passage around it that allows the water to flow. The water from the underground tank is then circulated through this structure, and a fan is attached to the end of the pipe to blow air into it. As the air moves through the pipe due to the force of the fan, heat exchange occurs with the surrounding water (for example, thin materials like plastic bottles conduct heat easily), and in the summer, it gradually cools down. If the length of the pipe is made long enough, the temperature at the pipe's outlet will approach the temperature of the water from the underground tank. In the summer, it will be cool, and if the air is below approximately 15°C, it will be warm. Alternatively, the structure can be made by connecting plastic bottles, for example. Fans such as electric fans consume little power, so it is energy-efficient. The pipe does not have to be straight and can be curved to increase the distance. A thinner pipe can be placed inside the main pipe so that water circulates there as well, making heat exchange easier when air blows on it. By placing rods made of metal or other materials with high thermal conductivity between the passage and the pipe through which circulating water flows, the surface area in contact between the water (around 15°C) and the incoming air can be increased. Fans can also be installed not only at the pipe's inlet but also at the outlet or along the way to improve heat exchange efficiency. This device can be installed indoors, but also at a constant ground temperature of about 5 meters underground. Air is brought in and out through pipes. If air is sent through pipes to a depth of about 5 meters underground where the ground temperature is around 15°C, the same effect will occur regardless of the season, such as in winter. Water flows on all four sides or in specific parts of the pipe, but in a two-tiered structure, the water in the lower section is maintained by gravity even without sealing the ceiling, so a ceiling may not be necessary, and the water can come into direct contact with the air, increasing heat exchange efficiency. If the ground temperature around most of the installation location for the pipe is around 15°C, the temperature of the original air, etc., will approach 15°C. Compressed air is used when using hot spring water or water artificially heated by boilers, etc., for air conditioning in homes and facilities.First, hot water or similar material is poured into a space created using plastic bottles, etc. In the method described above, heat exchange is used to bring the temperature of the air, etc., closer to 15°C by utilizing the underground temperature of about 15°C. If hot water is used instead of 15°C, that temperature will be achieved. To maintain the temperature when sending it, the plastic bottles are connected together and placed in a tube, and the compressed air (or a slight breeze, depending on the situation) is sent into the enclosed space. The above space for sending warm air can be installed underground or above ground, but if the ground is very cold, considering the cost of digging underground, it may be better to use a heating system using water from a tank about 5 meters underground at about 15°C. Since the depth of underground tanks may vary depending on the depth and season, multiple tanks can be prepared and water can be mixed. If necessary, the efficiency can be increased by covering the outside of this air-sending device made of plastic bottles with insulating material (such as styrofoam or other insulating material). Cold air can also be sent. By connecting plastic bottles or similar containers, a rectangular or other shape of space is created, and then more plastic bottles or similar containers are connected within that space to form a structure. Then, as described above, a space is created into which liquids can be poured, and the items to be dried or humidified are placed in the areas where air was previously supplied. At this time, it is possible to pack the containers tightly to prevent air from getting trapped, or to leave some gaps to allow warm air to flow through. For example, when evaporating seawater to extract salt... The system consists of a space filled with seawater, a space above which warm air can be circulated, and below that, a plate-like passage made from plastic bottles (which can be slightly sloped), with another space above that for water to flow. The outer perimeter can be enclosed with plastic bottles, and the entire interior can be pressurized with a compressor. Seawater evaporation is accelerated by the power of sunlight or by circulating warm water, and further accelerated by circulating warm air. When the humidity becomes high, the pressurized interior is returned to normal atmospheric pressure with a compressor, and cold water from an underground tank is circulated through pipes. As the humidity decreases and the nearby temperature cools, water droplets released from the air flow rapidly down the installed plate to the lowest point. This structure accelerates the evaporation rate of seawater. The outer perimeter, constructed from plastic bottles, can be covered with transparent film or plastic as needed to withstand the pressurization. When releasing the air from inside this device to the outside, filters to prevent salt damage can be installed near the outside air intake and exhaust fans. Salt damage is caused by fine particles generated when waves break being carried away by the wind, but this device does not generate fine particles in the first place, so it is installed only as a precaution. Hatches are made where ventilation is possible to withstand internal pressure. By making this device out of transparent materials such as PET bottles, the power of sunlight can be transmitted efficiently. Placing a black material (such as a black sheet) at the bottom of the device further utilizes energy from sunlight more efficiently. This device can also be installed in places where sunlight is needed, such as solar panels, to obtain salt while preventing the temperature of the solar panels from rising. The angle of the device can be adjusted by creating a base or similar structure out of transparent material such as PET bottles at the bottom, depending on the installation angle of the solar panels. When keeping fish, the space should be designed in a loop shape to prevent the fish from accelerating in a direction nearly perpendicular to the walls of the space containing water, thus preventing collisions. As shown above, a space can be created using plastic bottles or similar materials, and water can be added. The top can also be covered with a lid made from the same material as the plastic bottles. A pump can then be used to suck out the water and force it out under pressure, or compressed air can be sent in one direction to give the water a constant rotation. The width of the loop structure where the fish swim should be approximately 50 to 100 centimeters (this is just a guideline). Normally, electric compressors are used to compress air industrially, but this system utilizes the energy of water-powered gears or the rotational energy of wind turbines transmitted through gears to power the compressor. The compressed air tanks are then placed at a constant ground temperature of approximately 5 meters underground, or the compressed air is blown into water stored in tanks at a similar depth to bring the temperature close to 15°C. By using natural energy such as water power to power air compressors and storing it in cylinders underground, it can be retrieved like a battery and used to power gears when needed. When compressing air with a compressor, it can be cooled in underground tanks before compression to adjust humidity, or stored underground to lower humidity. Tanks containing compressed air can also be placed underground to lower their temperature. Even large-scale tanks can be installed without difficulty if placed underground. Using the above system, compressed air with adjusted temperature and humidity can be efficiently supplied from facilities to general households via underground pipes. Instead of storing electricity, it would be stored as compressed air (in gaseous form or like dry ice). A waterwheel-like structure could be installed beside a river. If the coastline is a ria coast, tsunamis can reach high elevations, so such a structure could be artificially created to bring seawater up to 10 meters above the coastline using the force of the waves. This water could then be stored and used to power hydroelectric turbines using gravity, or to drive air compressors. By obtaining the potential energy of large quantities of seawater semi-permanently using the energy of ocean waves, it could be useful for human life. Using this method, compressed air could be stored in cylinders, which could then be moved to a depth of 20 meters underground, or the cylinders could be fixed in place with a diameter of 20 meters. A tank filled with water could be prepared underground. Rotating wheels could be installed in these tanks, and compressed air released from below would rotate the wheels due to the energy generated during buoyancy. The deeper this tank is, the more wheels and other components can be installed, and the buoyancy will provide the energy to rotate the waterwheel and wheels.This waterwheel is highly efficient because it uses the rotational energy of its wheels to power a compressor to produce compressed air or a generator. Compressed air (gas), dry ice, and hydrogen gas (HHO·GAS, etc.) are placed in a deep point of a tall, narrow tank filled with liquid water or similar material, where water pressure is applied. Heat from electricity or chemical reactions is added to ignite the hydrogen gas (or a mixture of hydrogen and oxygen), causing the dry ice to expand into gas and the compressed air to generate upward kinetic energy against the water pressure (gravity). This energy is then applied to the waterwheel to rotate it. This energy is recovered and used to power a generator or other equipment. To increase the efficiency of the waterwheel's rotation, the blades are made movable and can be opened and closed. This allows them to open when pushed by the gas, receiving the kinetic energy and minimizing the reduction in rotational speed caused by resistance from the waterwheel blades hitting the liquid. The blades open and close, but not completely; they remain slightly open, allowing air to enter and push them open. Alternatively, plates or other supports can be attached to the blades of a water turbine in a tank to facilitate air collection. This blade shape is designed so that when a water turbine of this shape is installed in a tunnel or similar structure where there is no energy for air or other gases to rise and water pressure is applied, the blades will open where they are pushed by the water flow and close when the pressure from the water flow weakens. In large-scale hydroelectric power plants such as dams, there are some with a drop of 100 meters and pipes hundreds of meters long, but if the hydroelectric propeller is only attached to the downstream end, the energy of the water flow cannot be sufficiently recovered to turn the turbine of the generator, resulting in losses. Therefore, the drop should be around 10 meters, and the energy should be distributed through narrower pipe-like tunnels or tubes, or water turbines or hydroelectric propellers should be installed in sections where there was previously only water flow. This allows for the efficient recovery of the potential energy of the water flow. Furthermore, when compressed air or similar substances are ejected from a deep location with high water pressure, and when a water turbine or similar device is rotated by the upward force of the air or similar substance, if the water tank or similar device is designed in a way that the compressed gas or similar substance is ejected at approximately the 1 o'clock position when the water turbine or similar device is rotating clockwise, the deceleration of the propeller or water turbine due to water pressure can be suppressed.Compressed gas is ejected from the 6 o'clock position, etc., so a constant clockwise rotational force is maintained, converting the energy of the compressed air, gas, etc., and the buoyant force due to the density difference into rotational energy for the waterwheel, etc. When injecting compressed gas, etc. into a hollow shaft of the waterwheel, etc., a catch can be placed at the 1 o'clock and 6 o'clock positions, and when the hole in the shaft catches on it, the door opens and the gas is ejected. The door closes with the force of a spring or similar when it reaches a position where there is no catch. Alternatively, gas can be passed through the hollow part of the shaft and covered with a cap made of metal or similar material, and when a specific part of the cap is open, the gas can be ejected when the gas outlet on the rotating shaft reaches a specific position. Another method is to control the valve so that the compressed gas is ejected in conjunction with the position of the waterwheel, so that compressed gas is released only when it reaches a specific position. The shaft that transmits energy from water turbines and similar devices can be extended horizontally to enhance airtightness and prevent water from leaking out of the tank, or it can be routed to a part of the tank where there is no water. Alternatively, the shaft can be changed direction using gears inside the tank and the rotation transmitted to an upward-extending shaft. Once it reaches a height where it can come into contact with the outside air at the top of the tank, the energy can be transmitted back to the gears to be used as a power source. Multiple water turbines can be connected vertically. Various methods are possible, such as extending the tank deep underground or raising it high above ground. By utilizing the natural principle that the temperature around 5 meters underground in mainland Japan remains at approximately 15 degrees Celsius year-round, a tubular tunnel could be grounded there to save energy on cooling. Alternatively, this structure could be grounded above ground, with the outer circumference of the tube covered in liquid water or similar material for cooling. If the outer circumference is made of a light-transmitting material such as plastic or glass, passengers could still see the scenery from inside the vehicle. A similar tunnel could be filled with water or similar material to seal the interior of a ship, increasing energy efficiency during travel by creating a vacuum inside the tunnel (this can be applied to anything that can travel through a tunnel). Even smaller vehicles like cars can benefit from this structure, reducing energy costs and improving the reliability of autonomous driving. Vehicles could be connected to trolleys or similar platforms, with the weight of the vehicles primarily supported by the sleds, reducing rolling resistance. This trolley can incorporate motors or other devices to transmit power by contacting the road surface, or it can connect the power from the engine or motor of an automobile to the trolley's power unit while the automobile is mounted on the trolley, or it can be equipped with a device to transmit the rotational force of the automobile's wheels to the road surface as needed. There are various methods. Alternatively, even without using existing automobiles, a four-wheeled vehicle could have two extra wheels attached to the center of the vehicle body, so that these parts do not normally contact the ground during operation. However, by changing the angle or height using hydraulics, etc., it can be made to make contact with the ground. This allows the four wheels to ride onto the trolley, and the remaining two wheels (rubber, iron, etc.) to contact the upper part of the cooling rail as needed using hydraulics. Alternatively, the trolley could be equipped with a hydraulic jack function so that after the automobile is mounted on the trolley, the vehicle can be raised or lowered using hydraulics, etc., to change the height of the automobile's tires, etc., and prevent them from contacting the ground. Motors or other devices to provide driving force during operation can be installed on this bogie, or a portion of the bogie can be powered to pull or push it, or it can be coupled with other bogies like a train, or powered bogies can be appropriately placed to reduce installation costs.It is also possible to monitor the movement of the trolley (unit) with sensors or install cameras around the cooling lane so that the trolley can be controlled automatically and unmanned. Solar panels can be installed near the space where the cooling lane is installed, and the power from them can be used to guide the motor of the trolley from the metal part of the lane, or contactless power transmission can be used so that the electrical receiving part of the lane and the trolley do not have to come into direct contact. There are several ways to convert the energy of the car's engine or motor into driving energy by connecting it to tires (even iron wheels) that can be attached to the side of the tires of a car, etc., so that the rotation does not come into contact with the road surface or the upper part of the cooling rail where there is no ice, etc., on the trolley, etc. Another method is to attach a device to the trolley that rotates the roller part underneath when the engine etc is rotated in place without changing the position of the car passing through inspection, and connect it to wheels with a mechanism that converts the rotational energy of the roller part so that it does not come into contact with the road surface on the trolley wheels. To prevent the road surface, which transmits the energy used for propulsion, from freezing, water heated to about 15 degrees Celsius by geothermal energy stored 5 meters underground is guided through pipes to the vicinity of the road surface. The water is then collected in a tank by a motor pump and circulated. For emergency stops, stakes or similar objects are installed at the rear of the bogie, and these can be lowered to the road surface as needed to bring the train to a quick stop. Even when obtaining energy in the direction of travel using technologies such as linear motor cars, if a portion of the magnetic field of the linear motor car track is cooled and covered with ice, and skids or other devices that reduce resistance during movement are attached, the force that would otherwise be used for vertical levitation by electricity can be saved, and most of the electrical energy can be concentrated into energy for forward movement, making it more efficient. The direction of the magnetic energy acting on the levitation energy and the energy for acceleration in the direction of travel of a linear motor car is adjusted to conserve electrical energy as much as possible, such as keeping the levitation energy low, in order to balance power consumption and speed during movement to the most efficient extent. In practice, even if it is not levitating, the skids or other devices reduce resistance and allow it to move. A linear motor car may be fitted with a sled and the aforementioned powered wheels.By creating a near-vacuum state inside the tunnel, wind-induced losses are eliminated, and noise is reduced. The energy transfer section using magnetic force in a linear motor car and the sled equipment may be installed separately. To cool the parts in contact with the sled, long, narrow heat-absorbing plates from a freezer could be installed, or a dedicated heat absorption device or efficient temperature control using a large compressor and water at a constant temperature underground could be considered. The waste heat from the compressor could be reused to power a Stirling engine or similar. The compressor could be installed in a space where water drawn from 5 meters underground circulates around it via pipes, thus utilizing the heat dissipation for other purposes. Even on existing roads, to prevent freezing and lower road surface temperatures in summer, water from tanks installed 5 meters underground is circulated through pipes to about 10 centimeters below the asphalt surface, preventing the road surface from freezing or overheating. Circulating water around the sled via pipes could also improve cooling efficiency, especially in summer. Using plastic bottles or similar items, create a space the size of a futon (it can be larger or smaller, the size can be changed) and maintain a temperature that is cool in the summer and warm enough not to freeze in the winter. Water from a tank installed about 5 meters underground is fed into the plastic bottles through pipes and connected so that the water circulates and returns to the tank. By using motors to pump the water, or by installing large underground tanks in the ground of high mountains, or by linking them with large facilities such as water treatment plants, the water can be kept cool, close to 15°C even in summer, and delivered to each household, allowing for pumping using only water pressure. By attaching a sealed structure or cover to the top of cooling rails (lanes), etc., and circulating water at about 15°C from the underground tanks through it, the cost of cooling towers can be reduced. To prevent heat from escaping as much as possible, the top cover of the cooling rails and lanes is closed electrically, especially in the summer, but when vehicles pass by, sensors can be used to detect this and the cover can be automatically opened and closed by motors. When freezing liquids such as water inside cooling lanes, it is also possible to cool them by sending compressed air (carbon dioxide) or gas through pipes or other means that pass through the liquid or ice, using the heat of vaporization. For transporting objects, such as things, replace the wheels of a train with sleds or similar vehicles. Instead of rails, a width just wide enough for a sled to pass through is created, and water or other liquid is placed in this area and cooled using electricity or other means to freeze it, thereby reducing friction and minimizing energy loss. Wheels or other liquids are used to contact the gaps between the rails for acceleration and deceleration. When speed is reached, these wheels or other liquids can be retracted into the vehicle body using electricity or other means to reduce resistance and prevent contact with the ground. The sled portion slides on the frozen surface, but the rail structure has protruding shapes to prevent it from derailing sideways. Tires or other liquids that contact the sides of the rails may be attached to the sled to reduce impact on curves. The route is designed to slope slightly downwards, using gravitational energy to generate acceleration. While it's possible to design the route without elevation changes, the construction costs are calculated, and even if it slopes upwards, the friction is reduced by the skids, allowing the energy of inertia to be used to move the object to higher ground. Even with a slight downward slope, the resistance at the contact points of the vehicle is extremely low, so the vehicle can accelerate rapidly even with only a small amount of energy supplied by the contacting tires. The same applies to linear motor cars and other vehicles that do not make contact with the ground. Furthermore, the generation of air resistance is prevented by creating as much of a vacuum as possible inside the tunnel, such as a tube surrounding the vehicle. Possible methods include opening hatches on the vehicle at stations to create passages to the outside, or installing partitions or doors that open and close vertically within the tunnel, allowing air to be partially introduced at stations to allow passengers to enter and exit. By utilizing the natural principle that the temperature around 5 meters underground in mainland Japan remains at approximately 15 degrees Celsius year-round, a tubular tunnel could be grounded there to save energy on cooling. Alternatively, this structure could be grounded above ground, with the outer circumference of the tube covered in liquid water or similar material for cooling. If the outer circumference is made of a light-transmitting material such as plastic or glass, passengers could still see the scenery from inside the vehicle. A similar tunnel could be filled with water or similar material to seal the interior of a ship, increasing energy efficiency during travel by creating a vacuum inside the tunnel (this can be applied to anything that can travel through a tunnel). Even smaller vehicles like cars can benefit from this structure, reducing energy costs and improving the reliability of autonomous driving. Vehicles could be connected to trolleys or similar platforms, with the weight of the vehicles primarily supported by the sleds, reducing rolling resistance. This trolley can incorporate motors or other devices to transmit power by contacting the road surface, or it can connect the power from the engine or motor of an automobile to the trolley's power unit while the automobile is mounted on the trolley, or it can be equipped with a device to transmit the rotational force of the automobile's wheels to the road surface as needed. There are various methods. Alternatively, even without using existing automobiles, a four-wheeled vehicle could have two extra wheels attached to the center of the vehicle body, so that these parts do not normally contact the ground during normal driving, but can be made to contact the ground by changing the angle using hydraulics, etc. This allows the four wheels to drive onto the trolley, and the remaining two wheels to contact the ground as needed using hydraulics, etc. Another method is to give the trolley a hydraulic jack function so that after the automobile is mounted on the trolley, the vehicle on the trolley can be raised or lowered using hydraulics, etc., to change the height of the automobile's tires, etc., and prevent them from contacting the ground.There are several methods for converting the energy of a vehicle's engine or motor into driving energy. These include attaching a device to the side of the vehicle's tires to prevent them from rotating in contact with the road surface on a trolley, and connecting the vehicle's tires to the trolley to prevent the engine or motor from making contact with the road surface. Another method involves attaching a device to a trolley that rotates rollers underneath the tires when the vehicle rotates in place without changing its position during vehicle inspections, and connecting the rotational energy of these rollers to wheels on the trolley that have a mechanism to prevent them from making contact with the road surface. To prevent the road surface from freezing, water heated to about 15 degrees Celsius by geothermal energy stored 5 meters underground is guided to the vicinity of the road surface via pipes. The water is then collected in a tank by a motor pump and circulated. For emergency stops, stakes or similar objects are installed at the rear of the trolley, and these can be lowered to the road surface as needed to bring the vehicle to a quick stop. Even when obtaining lateral energy using technologies such as linear motor cars, if a portion of the magnetic field section of the linear motor car's track is cooled and covered with ice, and a skid is attached, the force that would otherwise be used for vertical levitation by electricity can be saved, and most of the electrical energy can be concentrated on lateral energy, making it more efficient. The direction of the magnetic energy acting on the linear motor car during its operation, which provides both levitation energy and acceleration energy in the direction of travel, can be adjusted to save as much electrical energy as possible. A skid and the aforementioned power wheels may be attached to the linear motor car. The tunnel can be kept in a near-vacuum state to eliminate losses due to wind and reduce noise. The energy transmission part using magnetic force in the linear motor car and the skid device may be installed separately. To cool the part in contact with the skid, a long, narrow heat-absorbing plate from a freezer can be installed, or a dedicated heat absorption device can be used, or efficient temperature control using a large compressor and water at a constant temperature underground can be considered. The waste heat from the compressor could be reused to power a Stirling engine or the like. By installing the compressor in a space where water or other fluids drawn from 5 meters underground are circulating through pipes, etc., heat dissipation measures can be utilized.Even on existing roads, to prevent freezing and lower road surface temperatures in summer, water can be circulated through pipes from tanks installed 5 meters underground beneath roads and walkways, preventing the road surface from freezing or overheating. Circulating water can also be routed through pipes around the sled area to improve cooling efficiency, especially in summer. Using plastic bottles, a futon-sized space (it can be larger or smaller, the size is adjustable) can be created to maintain a cool temperature in summer and a temperature that prevents freezing in winter. Water from tanks installed about 5 meters underground can be routed through pipes into the plastic bottles, which are then connected to circulate the water back into the tank. Using motors to pump water, or by installing large underground tanks in high mountains or linked to large-scale facilities such as water treatment plants, a temperature close to 15°C even in summer can be maintained, allowing water to be pumped using only tap water pressure. To make it easy and convenient to move electric bicycles and other means of transportation to their destinations, parking and storage locations will be provided near stations, etc. For example, electric bicycles will be available at the parking locations and can be unlocked mechanically. The wheels of the electric bicycles will be locked to keep them in the parking locations, and when a user wants to use an electric bicycle, they can launch a pre-registered smartphone app, agree to the terms of service, and click to start using it, and the linked locking device will automatically unlock, allowing them to use it. A wireless location-sharing device will be attached to the electric bicycles so that the administrator can know their location when needed. The smartphone used by the electric bicycle user and the location-sharing device will be linked wirelessly during use, and if they move a certain distance apart, the device attached to the bicycle will have an alarm function that will notify the user and administrator via email, etc. The location of the bicycle can also be automatically recorded and saved using the device. In the event that the distance between the bicycle and the user's smartphone becomes too great, safety will be ensured, such as by shutting off the motor current in the case of an electric bicycle. In a simpler system, when unlocking the locks securing bicycles in the parking area, the administrator can remotely activate the unlocking device via the internet after verifying the user's identity by confirming a password set in advance, along with the caller ID and name, over the phone. Alternatively, a password valid for a certain period of time can be communicated to the user via mobile phone, and the user must enter the password by pressing the unlock button on the parking space within that time to unlock it. When locking the parking area, the user's identity is verified by entering the password used for unlocking. Other methods include using fingerprint, facial, or eye recognition via dedicated smartphone software for identity verification, or using the video call function of a smartphone to verify the user's face and manner of speaking, allowing the administrator to remotely unlock the device. If the locking device for the parking area and the key for electric bicycles are separate, there is a possibility that only the parking area will be locked while the bicycle itself remains unlocked. Therefore, the electric bicycle's power should be automatically turned off if it is not operated for a certain period of time.The system involves setting a password using RSA encryption technology via computer, sending it to the locking device, and transmitting the unlock code via mobile phone, etc. Alternatively, a program is installed that automatically recognizes a password linked to the time of day, allowing administrators to communicate randomly changing passwords to users via mobile phone or email. The user is responsible for managing and using the bicycle, from the time of application to returning it properly to its storage location with the bicycle locked. The locking device notifies administrators and users via a server when the lock is released or locked. The parking area is equipped with motion-sensing cameras and light communication devices to record and notify administrators. For electric bicycles, the key to lock the tires is linked to the power supply of the electrical system. Users can choose to have multiple locking devices (one on the parking area and one on the bicycle itself) or to have all locks on the bicycle. If all locks are on the bicycle, administrators can safely unlock and lock the bicycle while monitoring the parking area status via video conferencing, live cameras, etc. In the case of multiple bicycles, security is enhanced by ensuring that when the lock is released, the key and battery of the bicycle can be removed when the locking device of the parking space is released. When locking, the key to the bicycle can be returned to the locking device of the parking space, and the administrator can confirm via a signal that the electric bicycle battery is charged. Once the locking device is locked, the key and battery of the bicycle cannot be removed. Even if the devices are installed together on the electric bicycle, the administrator can remotely check and manage the status of the electric bicycle, key, and battery using communication functions. A magnetic card key can be used as a means of identity verification by having the user authenticate it with a machine installed in the parking space, or it can be used in conjunction with the above methods. Payments can be linked to the card key or smartphone and automatically deducted from the bank. If a rain cover is attached to the electric bicycle, it can be used comfortably even in the rain.By connecting materials such as plastic bottles, a space is created for people to pass through, allowing for internal temperature control as they move through. The connected plastic bottles are filled with a liquid (such as water) that maintains a stable temperature throughout the year, typically found at a depth of around 5 meters underground (this is just an estimate). This liquid is then pumped up and circulated through the structure to regulate the internal temperature when the outside temperature is high or low. While groundwater temperature fluctuates annually depending on depth, this fluctuation is also utilized to the fullest extent for climate control. Assuming a natural outside temperature of around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of 15°C water over time. Therefore, to reach approximately 22°C, only about 7°C worth of energy is needed to maintain the air temperature, which is more efficient than raising it from 5°C. The same applies when lowering the temperature. If hot water such as spring water is available, it becomes even more efficient when raising the temperature for climate control. Specialized materials can be used for the plastic bottle-like objects, provided they meet the intended purpose. Installation locations can be selected based on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles are connected to allow water to flow through them. To do this, they are fixed with adhesive tape or similar material and the insides are hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. Plastic objects such as plastic bottles can be made transparent, allowing light to pass through while still creating an open space. If fish are kept inside, it can also be used as art. By changing the size of the space using similar structures, it is possible to fill it with hot water or create other leisure facilities, creating a space that is integrated with nature. It is possible to create a relaxing hot spring without worrying about rain or wind. The temperature inside the space and the temperature of the flowing water are managed by sensors, and the flow rate of electric pumps is automatically adjusted to keep energy costs at an optimal level. If installed in a mountainous area, nearby timber can be used, allowing for effective utilization of the heat generated by burning the wood. Water stored in underground tanks can be flowed through structures made of plastic bottles and then returned to the underground tanks. Electric pumps and other equipment are used to move water and other fluids. The water and other fluids are reused by circulating them in underground tanks and within structures such as plastic bottles.The above-mentioned leisure facilities can be used for keeping fish for viewing or fishing. By connecting materials such as plastic bottles, a space can be created for people to pass through, allowing for internal temperature regulation as they move through. By connecting materials such as plastic bottles, a liquid (such as water) with a stable temperature throughout the year, found at a depth of about 5 meters underground (this is just an estimate), can be placed inside and pumped up using an electric pump to circulate it, which can be used for internal air conditioning when the outside temperature is high or low. Groundwater temperature also fluctuates throughout the year depending on the depth, but this can also be utilized to the fullest extent for air conditioning. Assuming the natural outside temperature is around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of the circulating water if it is 15 degrees Celsius over time, so to maintain the air temperature at approximately 22 degrees Celsius, only about 7 degrees more energy is needed to maintain the air temperature, which is more efficient than raising it from 5 degrees Celsius. The same applies when lowering the temperature. If hot water such as hot springs is available, it will be even more efficient when raising the temperature for air conditioning, etc. The plastic bottle-like objects can also be made of specialized materials if they meet the purpose. The installation location can be selected depending on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles are connected to allow water to flow. For this purpose, they are fixed with adhesive tape or similar material and the insides are hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When raising fish in a temperature-controlled space created using such a structure made from plastic bottles, if the fish swim fast, the structure should be as streamlined as possible to allow them to swim in large circles. Setting the width in the direction of travel to 50 centimeters, according to the size of the fish, will prevent head-on collisions and ensure safety. In addition, by creating a difference in height in such a structure and moving the liquid from a lower position to a higher point with an electric pump, a water flow is created in a constant direction inside the space containing the liquid that is in contact with the fish, preventing collisions. The water flow can also be stopped temporarily when necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing geothermal energy, to create a structure where plants of varying sizes are grown. Plants are then planted and cultivated within this structure, and moved to a care area using rails or wheels, maintaining limited and controlled air circulation from the outside world, thereby preventing pollination and complying with plant variety laws. A space isolated from the outside world is constructed using plastic bottles, and this is connected to the plant cultivation area with a hatch. After a person enters and confirms that the space is clean, the connecting hatch is opened, allowing humans to directly care for the plants inside, or to care for them mechanically using robotic arms and remote cameras. Plants transported to the care area via rails can be remotely monitored by cameras, and tasks such as thinning the plants can be automated through AI learning by installed machinery. When using materials such as PET bottles to construct a space, circulating liquids within it and utilizing the temperature of liquids in an underground tank for heating or cooling the space, it is possible to artificially heat (using equipment such as oil boilers) or cool (using equipment such as refrigerators or liquid nitrogen) the circulating liquids. However, it is also possible to use solar heat to heat the space, and the structure made of PET bottles can be used as a solar thermal storage water heater, saving on energy costs. By concentrating sunlight around the structure made of PET bottles, protecting the surroundings with airtight materials such as aluminum, and adding insulation, the heat retention efficiency can be improved. Structures made of materials such as PET bottles can have adequate space inside to grow plants, etc. If water or other liquids are circulated inside the PET bottles and transported via pipes connected to an underground tank, the temperature of the underground will be transferred to the inside of the space. The PET bottles act as a shield, blocking the space between the temperature-transmitting substance such as water and the surrounding space. If you are not pouring liquids that utilize underground temperatures into plastic bottles or similar containers, you can reduce the energy costs associated with artificially regulating the temperature inside the space using air conditioners or boilers by covering the container with a heat-insulating or heat-retaining material.When creating internal spaces in objects made from plastic bottles or similar materials, if the spaces are arranged in multiple levels, and sunlight cannot reach the lower spaces adequately due to objects placed inside the upper spaces, one method is to concentrate sunlight at an appropriate position and transmit it to the necessary locations using optical fibers. Alternatively, one can use mirrors or other reflective devices to refract light and guide it from areas with good light to areas with poor light, either on the sides of the structure made from plastic bottles or elsewhere. Since plastic objects like plastic bottles can be made transparent, it is possible to create an open space that allows light to pass through but is blocked, and it can be used as art if fish are kept inside. By changing the size of the space using a similar structure, it is possible to put hot water inside. It is possible to create spaces that are integrated with nature by incorporating things like hot springs and other leisure facilities. It is also possible to create relaxing hot springs that can be enjoyed without worrying about rain or wind. The temperature inside the space and the temperature of liquids such as flowing water are controlled by sensors, and the flow rate of electric pumps is automatically adjusted to keep energy costs at an optimal level. If installed in a mountainous area, nearby timber can be used, and the heat generated from burning the timber can be effectively utilized. In this way, competitive agricultural products can be produced by minimizing costs as much as possible, and these products can be given away for free to poor young people, or a coupon-like certificate can be issued based on a set of rules that stipulates that certain services will be provided in return. The costs related to production and services can be significantly reduced, and this can be used as a basis for building a coupon-like concept, perhaps by patenting it. The coupon can also be considered as a concrete entity of the concept. If person A owns an agricultural production site and also owns restaurants and recreation facilities, they can manage the usage fees with such coupons and use them to pay for daily service businesses, and recruit businesses to participate in a community-like group. Negotiations can also be made to allow the use of these coupons at restaurants and recreation facilities managed by people other than A. Restaurants and recreational facilities can earn money by serving or selling agricultural products as dishes. Even if recreational facilities have considerable labor costs, they can use this coupon if it includes services that involve such contracts. Efforts should be made to allow the use of this coupon not only for recreational facilities but also for service industries that normally handle payments in currency such as yen. If person A is a business owner and receives payment for services in yen as usual, income is generated, which may be collected by the government and distributed to the poor for welfare (such as social welfare). However, by having people like person A and others participating in this system cover this role, we can raise awareness of the meaning of receiving services and other basic human needs, and reduce the government taxes associated with this work. We can secure food, which is the basis of human life, and enable people to live on that.If person A manages this system, farmers and service providers can join, alleviating concerns that they might only receive money of very low relative value in the market. Service providers can also find sufficient social significance in this coupon system to be satisfied with. This system allows for the creation of a stable society by constructing an income redistribution system. Furthermore, since this coupon system is based on voluntary participation, A can choose whether or not to allow others to participate and can also determine the terms and conditions of the contract. A can decide whether or not to allow the redemption of coupons. It is also possible to make it so that redemption is only possible through A. Whether or not A redeems coupons is entirely A's free will. It is also possible to decide that different types of coupons can be exchanged through A. A also has the right to exchange coupons and issue new coupons freely at will. A coupon is a concept. Coupons can be paper-based or electronic. If digitized, the data can be encrypted with PGP encryption and centrally managed in a database, allowing A to track the connections between goods, coupons, and services. Person A is free to decide whether or not to make this data publicly available. Since it relies on trust, interference by third parties is prevented to ensure stability. When replacing coupons with cryptocurrency, the value of the currency can be predetermined, such as "this many strawberries per coupon." The contract can also stipulate that cryptocurrency exchange can only be done through Person A. To cool, heat, or maintain the temperature inside a house or other object, water can be placed in a tank underground and flowed onto the roof. The ground temperature at a depth of about 5 meters underground is around 15°C year-round in Honshu, Japan, although this varies depending on the latitude. A tank can be prepared there, filled with well water, and then pumped using an electric pump or, if from a high point like a mountain, using water pressure to guide the water through pipes onto the roof and flow it at an appropriate rate. The flowing water can be collected using gutters and returned to the tank. The tank can also be partitioned to prevent the returning water from mixing with the water in the tank until it has cooled to a certain extent.The height of the sill inside the tank can be adjusted to control how much water accumulates before it overflows into an adjacent tank. Multiple tanks can be used, with the returning water stored in a separate tank for a certain period before flowing back into the original tank when it's full. Partitions may not be necessary if the tank capacity is large or the amount of water being discharged is small. The amount of water discharged can also be adjusted by adjusting the output of the water pump. Similarly, water can be discharged onto roads to cool them in the summer and melt snow or prevent freezing in the winter. The amount of water to be discharged can be programmed in advance using temperature data from weather forecasts, or the amount of water discharged can be controlled by adjusting the output of the water pump based on the actual temperature. If using spring water from mountains or well water (spring water sources and well water have stable temperatures throughout the year), a tank may not be necessary. If you want to adjust the amount of water discharged, you can install valves on the pipes that lead the water to the roof, etc., and attach a device that can control the diameter of these valves, or use a faucet system and control the opening and closing amount with a computer to control the water flow. While tanks don't necessarily need to be installed underground, using water whose temperature is controlled by the ground temperature allows for temperature control inside houses and other structures with less water, reducing costs such as electricity bills for water pumps. Making the tank long and narrow and extending to a depth of 5 meters or more underground, increasing the volume at deeper points, and circulating the water with a motor helps prevent freezing. It's also possible to install and connect tanks both underground and above ground to mix the water at the optimal temperature ratio. Since temperatures vary with depth underground, installing multiple tanks at different depths and connecting them with pipes to mix the water and flow it down the roof of the house or other structures can improve efficiency. When flowing water down the roof of a house or other structure, the water temperature and heat of vaporization should be calculated to determine the most efficient flow rate. If water is guided by pipes to the highest point of the roof or other structure, gravity will cause the water to flow down the roof or other structure. Water can also be guided by pipes to flow not only down the roof but also down the sides of the house or other structures (for example, water can be guided by pipes above windows so that it flows down the sides of the windows). If the roof has a diameter of 5 meters, then making the pipes on the roof section about 5 meters long will allow water to flow across the entire roof. The pipes have holes at appropriate intervals (they don't necessarily have to be 5 centimeters apart, for example), and water comes out from there.In winter, the ground temperature at a depth of about 5 meters underground is around 15°C, and this is utilized by circulating it through pipes under the flooring, sides, and ceilings of houses, etc., and collecting it in underground tanks for reuse. If hot spring water is used, even hotter liquids (water) can be circulated. To reduce the risk of a patent holder being sued by others over their patent, the entire process necessary for the patent is described in detail from beginning to end in the claims when the patent is obtained. If the patent holder uses the patent in a way that reproduces what is written in the patent, the risk of being sued by a third party for infringement or having to pay damages is minimized. All manufacturing processes, materials, methods, and technical processes are described in the patent. All procedures, materials, and phenomena in the processes when executing the patent are described in writing in the claims. Once a patent is granted, there is a system in place that allows anyone to anonymously file objections to that patent for six months. However, patent attorneys can also file objections, as they are bound by confidentiality obligations stipulated in the rules, meaning they are stakeholders who know the contents earlier than the general public. People who can view the patent-related documents at the Japan Patent Office also know the contents before the patent is published, so if such people conduct investigations well in advance, it could give them a unilateral advantage. Therefore, we will convey our opinion to the relevant organizations to stop anonymous objections and ask them to change the rules. We will connect materials such as plastic bottles to create a space where people can pass through, and allow for internal temperature control when moving through. We will connect materials such as plastic bottles and prepare a liquid (such as water) with a stable temperature throughout the year, such as water, at a depth of about 5 meters underground (this is just an estimate), and pump it up inside using an electric pump to control the internal temperature when the outside temperature is high or low. Groundwater temperature also fluctuates throughout the year depending on the depth, but we will make the most of this for air conditioning. Assuming the natural outside temperature is around 5 degrees Celsius, and the structure is sufficiently shielded, the internal air temperature will approximate that of the flowing water (if it's 15 degrees Celsius) over time. Therefore, to reach approximately 22 degrees Celsius, only about 7 degrees of energy is needed to maintain the air temperature, which is more efficient than raising it from 5 degrees. The same applies when lowering the temperature.If hot water such as from a hot spring is available, it becomes even more efficient when raising the temperature of air conditioning, etc. If the intended use is met, specialized materials can be used for objects like plastic bottles. Installation locations can be selected depending on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on the temperature. The plastic bottles are connected to allow water to flow. For this purpose, they are fixed with adhesive tape or similar material and the inside is hollowed out. The structural purpose is to create a temperature barrier between the liquid and the outside air to maintain temperature. When raising fish in a temperature-controlled space created using such a structure made from plastic bottles, if the fish swim fast, the structure should be as streamlined as possible to allow them to swim in large circles. Setting the width relative to the direction of travel to 50 centimeters, according to the size of the fish, ensures safety by preventing head-on collisions. Furthermore, by creating a height difference in such structures and using an electric pump to move the liquid from a lower position to a higher point, a consistent water flow is generated within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be stopped temporarily as needed. A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing geothermal energy, to create a structure where plants of varying sizes are grown. Plants are then planted and cultivated within this structure, and moved to a care area using rails or wheels, maintaining limited and controlled air circulation from the outside world, thereby preventing pollination and complying with plant variety laws. A space isolated from the outside world is constructed using plastic bottles, and this is connected to the plant cultivation area with a hatch. After a person enters and confirms that the space is clean, the connecting hatch is opened, allowing humans to directly care for the plants inside, or to care for them mechanically using robotic arms and remote cameras. Plants transported to the care area via rails can be remotely monitored by cameras, and tasks such as thinning the plants can be automated through AI learning by installed machinery.When using a space constructed from materials such as plastic bottles to circulate liquids and utilize the temperature of liquids in an underground tank for heating or cooling the space, it is possible to artificially heat (using equipment such as oil boilers) or cool (using equipment such as refrigerators or liquid nitrogen) the circulating liquid to further cool or heat the space. However, it is also possible to use the heat from sunlight to heat the space, and the object constructed from plastic bottles can be used as a solar thermal storage water heater, saving on energy costs. By concentrating sunlight around the object constructed from plastic bottles, protecting the surroundings with airtight materials such as aluminum, and adding insulation, the heat retention efficiency can be increased. The structure constructed using materials such as plastic bottles has an appropriate amount of space inside. While it's possible to create spaces inside these containers to grow plants, if a liquid such as water circulates inside the plastic bottles, and that water is transported via pipes connected to an underground tank, the underground temperature will be transferred to the space. The plastic bottles act as a shield, blocking the space from the temperature-transmitting substance such as water. If no liquid utilizing the underground temperature is circulated inside the plastic bottles, covering them with heat-retaining or insulating materials can reduce the energy costs associated with artificially regulating the temperature inside the space using air conditioning or boiler equipment. When creating spaces inside objects constructed from plastic bottles, and the spaces are arranged in multiple levels, if sunlight cannot reach the lower spaces sufficiently due to objects placed inside the upper spaces, methods can be used to concentrate sunlight at an appropriate position and transmit it to the necessary locations using optical fibers. Alternatively, reflective devices (such as mirrors) can be installed on the sides of the plastic bottle structure or other locations where light easily reaches, refracting the light and guiding it from areas with good sunlight to areas with poor sunlight. Plastic objects like PET bottles can be made transparent, allowing light to pass through while creating an open space that is otherwise blocked. This space can also be used as art by keeping fish or other marine life inside. By changing the size of the space using similar structures, it's possible to fill it with hot water or other leisure facilities, creating a space integrated with nature. This allows for the creation of relaxing hot springs, unaffected by rain or wind. Sensors can monitor the temperature inside the space and the temperature of the flowing water, automatically adjusting the flow rate of electric pumps to optimize energy costs. When installed in mountainous areas, nearby timber can be used to heat the surrounding water or the interior, effectively utilizing the heat generated by the wood's combustion and exhaust gases. Plants can be grown within structures constructed using materials like PET bottles. Since the interior space doesn't require human access, plants can be transported using wheels, rails, or motors, like a train. Removal is done in a similar manner.A pipe connects the structure to a tank located about 5 meters underground (the depth can be adjusted depending on the temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using a heating device). Water is then drawn from the tank using a motor pump and poured onto the exterior of the structure. By constructing the structure with steps or other elevation changes, liquid water or coolant can be poured onto the highest point of the structure, preventing it from falling all at once and maintaining a surrounding environment of liquids with different temperatures. This allows the structure to be cooled or heated. Piping for water intake can be installed at appropriate points on the structure, allowing the water to be returned to the underground tank. If the structure is made of plastic bottles, holes can be made in the sides of the bottles when connecting them, allowing the water inside the vertically or horizontally connected bottles to be moved as desired. Structures constructed from plastic bottles can have water circulated between tanks using a motor pump or similar power source. However, instead of doing so, they can be filled with an antifreeze suitable for insulation (clear is usually better for this purpose, but colored ones may be acceptable in some cases), or with light-transmitting materials such as water, glass, marbles, or plastic resin (colored materials may be better in some cases to adjust the amount of sunlight; a light-blocking cover can also be placed on the outside). By continuously circulating water from underground tanks or hot springs to the outside of the structure, and then collecting and recirculating it, the temperature inside the structure can be regulated. This can improve the installation cost and strength of the structure. Structures made from plastic bottles are not limited to plastic bottles; specialized materials can also be used. One application is to separate the internal space constructed from plastic bottles from the outside air. Plastic bottle-like materials can be connected to create a space that people can pass through, allowing for temperature regulation as they move through. Connecting materials such as plastic bottles, fill them with a liquid (such as water) that maintains a stable temperature throughout the year, typically found at a depth of about 5 meters underground (this is just an estimate). Then, using an electric pump or similar device, circulate this liquid inside to regulate the internal temperature, whether it's high or low.Groundwater temperature also fluctuates annually depending on depth, but this can be utilized to the fullest extent for air conditioning and other purposes. Assuming the natural outside temperature is around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of the flowing water (15°C) over time. Therefore, to reach approximately 22°C, only about 7°C worth of energy is needed to maintain the air temperature, which is more efficient than raising it from 5°C. The same applies when lowering the temperature. If there is hot water such as a hot spring, it becomes even more efficient when raising the temperature for air conditioning and other purposes. If the purpose is met, specialized materials can be used for objects such as plastic bottles. The installation location can be selected according to the purpose, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on the temperature. The plastic bottles are connected to allow water to flow. For this purpose, they are fixed with adhesive tape or similar material and the inside is hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When raising fish in a temperature-controlled space created using materials such as plastic bottles, the structure should be as streamlined as possible to allow fish to swim in large circles, especially if they swim quickly. Setting the width in the direction of travel to 50 centimeters, depending on the size of the fish, will prevent head-on collisions and ensure safety. Furthermore, by creating elevation differences within such structures and using electric pumps to move liquid from a lower position to a higher one, a consistent water flow is generated within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be stopped temporarily as needed. By circulating liquid such as water using geothermal energy within a space constructed using materials such as plastic bottles, and providing an efficient space for plants to be grown within the structure, the plants can be planted and cultivated, and then moved using rails or wheels while maintaining limited and controlled air circulation from the outside world to a workspace for plant care, pollen cross-pollination can be prevented, complying with plant variety laws and regulations.A space isolated from the outside world is constructed using plastic bottles, etc., and connected to a space where plants are grown with a hatch. After confirming that a person can enter the space and keep it clean, the connecting hatch is opened, and the plants inside the space can be directly cared for by a person, or cared for mechanically using a robotic arm with remote cameras. Plants are transported to the work area using rails, etc., and can be remotely monitored by cameras, and tasks such as thinning the plants can be automated through AI learning by installed machinery. Liquids can be circulated in the space constructed from materials such as plastic bottles, and the temperature of the liquid in an underground tank can be used to heat or cool the space. When further heating or cooling the space, the circulating liquid can be artificially heated (using equipment such as oil boilers) or cooled (using equipment such as refrigerators or liquid nitrogen), but the object constructed from plastic bottles can also be used as a solar thermal storage hot water system by utilizing the heat of sunlight, thus saving on energy costs. By concentrating sunlight around an object constructed from plastic bottles, protecting the surroundings with airtight materials such as aluminum, and adding insulation, the heat retention efficiency can be improved. Structures made from plastic bottles can have adequate space inside for growing plants, etc. If a liquid such as water circulates inside the plastic bottles, and that water is transported via pipes from an underground tank, the underground temperature will be transferred to the interior space. The plastic bottles act as a shield, blocking the space between the temperature-transmitting substance (water, etc.) and the interior space. If no liquid utilizing underground temperature is circulated inside the plastic bottles, covering them with heat-retaining or insulating materials can reduce the energy costs associated with artificially regulating the temperature inside the space using air conditioning or boiler equipment.When creating internal spaces within objects made of plastic bottles or similar materials, and the spaces are arranged in multiple levels, if sunlight cannot reach the lower spaces due to objects placed inside the upper spaces, a method can be used to concentrate sunlight at an appropriate position and transmit it to the necessary locations using optical fibers. Alternatively, reflective devices (such as mirrors) can be installed on the sides of the structure made of plastic bottles or other locations where light easily reaches, refracting the light and guiding it from areas with good light to areas with poor light. Since plastic objects like plastic bottles can be made transparent, it is possible to create an open space that allows light to pass through but is blocked, and it can be used as art if fish are kept inside. By changing the size of the space using a similar structure, it is possible to create a space that is integrated with nature by filling it with hot water or other leisure facilities. It is possible to create a relaxing hot spring that does not require worrying about rain or wind. The temperature inside the space and the temperature of the flowing water or other liquids can be controlled with sensors, and the flow rate of electric pumps can be automatically adjusted to maintain an optimal energy cost. When installed in mountainous areas, the structure can utilize nearby timber to heat surrounding water or the interior, effectively utilizing the heat generated by the combustion of wood and exhaust gases. Plants can be grown inside structures constructed using materials such as plastic bottles. Since the interior space of the structure does not need to be accessible to people, plants placed on pallets can be transported there using wheels, rails, or by connecting them like a train with motor power. The same applies when removing the plants. Pipes can be connected to a tank located about 5 meters underground (the depth can be adjusted depending on the temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using heating equipment), and water can be drawn from the tank using a motor pump and poured onto the exterior of the structure. If the structure's exterior is constructed with steps or other features, liquid water or coolant can be flowed to the highest point of the structure, preventing it from falling all at once and maintaining a balance of temperatures around it. In this way, the structure can be cooled or heated. Piping for water intake can be installed at appropriate points in the structure, allowing water to be returned to the underground tank.When constructing a structure using plastic bottles, holes can be made in the sides of the bottles when connecting them, allowing the water inside the connected bottles to be moved as desired. While structures constructed from plastic bottles can have water circulated between tanks using a motor pump, it's also possible to leave them filled with a suitable antifreeze (clear is generally better for this purpose, but colored is acceptable in some cases), water, glass, marbles, plastic resin, or other light-transmitting materials (colored materials may be better in some cases to adjust the amount of sunlight; a light-blocking cover can also be placed on the outside). This allows for temperature control within the structure by circulating water from underground tanks or hot springs to the outside, then collecting and recirculating it. This can improve the cost-effectiveness and strength of the structure. Structures using plastic bottles are not limited to plastic bottles; specialized materials can also be used. One application of structures constructed from plastic bottles is to separate the internal space from the outside air. For example, when creating a multi-purpose space inside a structure made from plastic bottles or similar materials. When liquids poured from a container move due to gravity, gaps can be created between structures made of plastic bottles, or a certain rim-like step can be added to the edges of structures made of plastic bottles to control the movement of the liquids and improve the efficiency of transferring the liquid's temperature to the constructed space inside. If natural spring water, hot spring water, or river water is placed in multiple or single tanks installed underground at high altitudes and then transported by gravity to plastic bottle structures at slightly lower altitudes using pipes, the electricity costs for pumps and other equipment can be almost eliminated, making it eco-friendly (theoretically possible to use only natural energy). When placing liquids in spaces made of plastic bottles and allowing fish to swim, the swimming area of ​​the structure can be made streamlined to reduce the risk of fish colliding with obstacles. The entire structure can also be made into a large loop shape, and water pressure can be created using pumps and fans to generate water flow inside the space. Creating a space with a large circle and a gently curved structure can prevent fish from coming into contact with walls, etc. If the space for fish to swim is about 50 centimeters wide (this is just a guideline, and depends on the size of the fish), it will help prevent the fish from colliding with the sides. For heat control using groundwater, etc., and for the space where temperature is regulated using that, by arranging structures made of plastic bottles etc., you can put a liquid for temperature regulation inside and create a space around it where plants or people can enter, and you can freely choose the arrangement. By attaching a structure made of plastic bottles etc. with spaces of the appropriate size inside to a tank set to a certain temperature, the temperature of the liquid in the tank may affect the space inside the structure made of plastic bottles etc., and the temperature of that space can be regulated. The space can be sealed, or air can be introduced or removed through filters etc. When shielding, a transparent, light-transmitting material, strong plastic, or a structure made by connecting PET bottles (or other specialized materials) can be used. Water can be pumped into the parts of the PET bottles that originally contained juice, from an underground tank located about 5 meters underground at a temperature of around 15 degrees Celsius year-round (depending on latitude, etc.), using a pump (or, in mountainous areas, the energy of gravity to naturally cause the water to fall). By circulating the water, the space where vehicles pass will be brought close to 15 degrees Celsius, and by adjusting the flow rate of the liquid, the cost of air conditioning in vehicles can be reduced. When reducing the pressure in the space where vehicles drive to reduce air resistance and create a near-vacuum state, the perimeter of the space can be reinforced by installing pressure-resistant reinforced plastic or glass. When circulating water with a pump, liquids like water do not suddenly boil even when exposed to sunlight from the outside, so the pump does not need to be run frequently, resulting in low energy costs. When obtaining energy from solar panels, solar panels can be installed on the roof of this equipment, or in empty spaces on the sides or lanes. To cool solar panels, water kept at a constant temperature in an underground circulating tank is flowed over the panels, or a pipe-like structure made of a light-transmitting material is installed nearby, through which water at around 15°C from the underground tank is flowed to control the temperature of the solar panels. Alternatively, the solar panels can be made waterproof and airtight, and placed in a shallow container of water, through which water at around 15°C from a depth of about 5 meters underground is flowed and then collected back into the underground tank. If the location allows for natural groundwater to flow, a continuous flow system is also acceptable to control the panel temperature. A structure can be constructed by cutting off the opening of a plastic bottle, for example, and gluing together multiple rectangular cubes to create a structure into which water from the underground tank can be placed. A hollow structure can be created using a material that transmits light but does not allow water to pass through, such as a plastic bottle, to hold water. The hollow section can then be used to place solar panels or other items whose temperature needs to be controlled.This method can increase power generation by installing a similar device in home solar panels, as solar panels reduce power generation when they get too hot. Furthermore, the water in the underground tank, at around 15 degrees Celsius, is used to efficiently air-condition the space. Since the ground temperature around the underground tank varies with depth, multiple tanks can be installed at different depths, and the water from these tanks can be mixed. The structure, made from plastic bottles, can be moved by draining the water as needed. Because the material is lightweight, this can be done manually, but the ceiling can also be constructed in advance to allow for opening and closing with a motor. A structure is created by placing pipes approximately 5 cm long and wide (this is just a guideline; the scale can be freely changed) inside the underground tank, and then installing a passage around them to allow the water to flow. A fan is attached to the end of the pipe to blow air through. As the air moves through the pipe, heat exchange occurs with the surrounding water (for example, thin materials like plastic bottles conduct heat easily), gradually cooling the water in the summer. By making the pipe long enough, the temperature at the pipe's outlet will approach the temperature of the water or other fluids from the underground tank. In summer, it will be cool, and if the air temperature is below about 15°C, it will be warm. For example, you can also create a structure by connecting plastic bottles. Fans such as electric fans consume little power, so this is energy-saving. The pipe does not have to be straight; it can be curved to increase the distance. You can also run a thinner pipe inside the main pipe and circulate water or other fluids through it to facilitate heat exchange when wind blows on it. You can also place a rod made of a metal with high thermal conductivity between the passage where the circulating water or other fluids are flowing and the pipe to increase the surface area in contact between the water or other fluids at around 15°C and the flowing air. You can also install fans not only at the inlet of the pipe but also at the outlet or along the way to improve heat exchange efficiency. This device can be installed indoors, but it can also be installed underground at a constant ground temperature of about 5 meters. Air is brought in and out through pipes.If air is sent through a pipe to a depth of around 5 meters underground where the ground temperature is about 15°C, then in the summer, the air drawn in above ground will circulate underground and exit the pipe again, its temperature approaching the ground temperature of 15°C. The same applies regardless of the season, even in winter. Water flows on all four sides or in specific parts of the pipe, but in a two-tiered structure, the water is maintained by gravity even without sealing the ceiling of the lower section, so a ceiling may not be necessary, and the water comes into direct contact with the air, increasing the heat exchange efficiency. If the ground temperature around most of the installation location of the pipe is about 15°C, the temperature of the original air will approach 15°C. Compressed air is used when using hot spring water or water artificially heated by boilers for air conditioning in homes and facilities. First, hot water or similar material is poured into a space created using plastic bottles, etc. In the method described above, heat exchange is used to bring the temperature of the air, etc., closer to 15°C by utilizing the underground temperature of about 15°C. If hot water is used instead of 15°C, that temperature will be achieved. To maintain the temperature when sending it, the plastic bottles are connected together and placed in a tube, and the compressed air (or a slight breeze, depending on the situation) is sent into the enclosed space. The above space for sending warm air can be installed underground or above ground, but if the ground is very cold, considering the cost of digging underground, it may be better to use a heating system using water from a tank about 5 meters underground at about 15°C. Since the depth of underground tanks may vary depending on the depth and season, multiple tanks can be prepared and water can be mixed. If necessary, the efficiency can be increased by covering the outside of this air-sending device made of plastic bottles with insulating material (such as styrofoam or other insulating material). Cold air can also be sent. It's also possible to circulate or temporarily store water, such as water at a depth of about 5 meters underground, by running thin pipes near objects like solar panels, where efficiency increases when the temperature is close to a certain level.Furthermore, in this state, solar panels and other devices (including any necessary shielding equipment) can be placed within a structure made of materials such as connected plastic bottles around their perimeter to eliminate the influence of outside air and control temperature. This structure can be filled with water utilizing the geothermal temperature from a depth of 5 meters underground, thereby controlling the temperature inside the structure and preventing the solar panels from overheating. The water can circulate or remain still within the structure made of connected plastic bottles, and the flow rate can be changed by adjusting the pump. The water that passes through the plastic bottles returns to the underground tank, where its temperature is controlled by the geothermal temperature. Multiple underground tanks may be installed depending on the depth. To control the temperature of the solar panels, the circulating water can be passed through even finer pipes, or such pipes can be pre-installed on the solar panels and other devices. Water from underground tanks can be passed through thin, light-transmitting pipes and placed around the solar panels for temperature control. Waterproofing measures should be taken for the pipes and solar panels to prevent water from entering the electrical equipment. Instead of using plastic bottles, thinner, specially designed materials can be used to create structures through which water or other liquids can flow. For example, a thin wall of water or other liquid, about two centimeters thick, can be used around the perimeter of solar panels to control their temperature. Water from an underground tank can be pumped up to a certain height and then, due to gravity, flow around the solar panels through pipes and return to the underground tank. Water (or a mist-like substance) can also be sprayed onto the solar panels to lower the temperature, and in this case, the water from the underground tank can be recovered and recycled. Structures made from plastic bottles can also be designed with multiple layers, such as a space for fertilizer to be poured and recovered, or a layer for water and oxygen to seep into the ground. By covering the top with a similar structure to create a sealed environment, the scattering of fertilizer, pesticides, etc., to the outside can be prevented. Cost reductions can also be achieved by reusing fertilizer, etc. When bringing in outside air, you can add doors to the top or elsewhere and open them, or use fans to let in air, and you can also create doors for people to enter.Such barriers can also prevent fertilizers used in agriculture from spreading outwards. In a space constructed using plastic bottles, etc., a tunnel-like space can be created inside, just wide enough for a person to pass through, and a trolley-like structure can be pulled in using rails or wheels. In hydroponics, the solution can be placed inside the space, and if cultivating plants, buckets of water of the appropriate size can be placed on the trolley and moved inside the space according to the growth of the roots. Plants can be moved on pallets using rails, etc., so they can be moved to any desired location by laying rails in a sunny place or rolling them on wheels. When cultivating plants hydroponically, the part of the plant above the roots can be moved on an upper trolley, reducing the force required to pull it. Similarly, a space can be created using plastic bottles, etc., where a car can enter, and the temperature inside the space can be controlled using circulating water, allowing the car to be parked and the interior to be used for resting. Structures made from plastic bottles, etc., can also be placed on top of this to cultivate crops. Normally, electric compressors are used to compress air industrially, but the power for these compressors could be derived from the energy of water-powered gears or the rotational energy of wind turbines transmitted through gears. The compressed air tanks could be placed at a constant ground temperature of about 5 meters underground, or the compressed air could be blown into water in tanks located at a similar depth to bring the temperature close to 15°C. By using natural energy such as water power to power air compressors and storing it in cylinders installed underground, it can be retrieved like a battery and used to power gears when needed. When compressing air with a compressor, it could be cooled in an underground tank before compression to adjust humidity, or the air could be stored underground to lower humidity. Tanks containing compressed air can also be placed underground to lower the temperature. Even large-scale tanks can be installed without difficulty if they are underground. Using the above mechanism, compressed air with adjusted temperature and humidity could be efficiently supplied from facilities to general households through underground pipes.Instead of storing electricity, it would be stored as compressed air (in gaseous form or like dry ice). A waterwheel-like structure could be installed beside a river. If the coastline is a ria coast, tsunamis can reach high elevations, so such a structure could be artificially created to bring seawater up to 10 meters above the coastline using the force of the waves. This water could then be stored and used to power hydroelectric turbines using gravity, or to drive air compressors and other power sources. By obtaining the potential energy of large quantities of seawater semi-permanently using the energy of ocean waves, it could benefit human life. This method could involve storing compressed air in cylinders and moving them to a depth of 20 meters underground, or by having cylinders with a diameter of 20 meters permanently stationary. A tank filled with water could then be prepared underground. Rotating wheels could be installed in these tanks, and compressed air released from below would cause the wheels to rotate due to the energy of the rising air. The deeper the tank, the more wheels could be installed. The buoyancy of the waterwheel or wheels generates energy that rotates them. This rotational energy can be used to power a compressor to produce compressed air or a generator, making it very efficient. Compressed air (gas), dry ice, and hydrogen gas (HHO-GAS, etc.) are placed in a deep point of a tall, narrow tank filled with liquid water or similar liquid, where water pressure is applied. Heat from electricity or chemical reactions is added to ignite the hydrogen gas (or a mixture of hydrogen and oxygen), causing the dry ice to expand into gas. The compressed air also generates upward kinetic energy against the water pressure (gravity), and this energy is applied to the waterwheel or other components to rotate them. This energy is then recovered to power a generator or other components. To increase the efficiency of the rotation of the waterwheel or other components, the blades of the waterwheel can be made movable and openable. This allows them to open when pushed by the gas, receiving the kinetic energy and minimizing the reduction in rotational speed caused by resistance from the waterwheel blades hitting the liquid. The blades open and close, but they don't close completely; they remain slightly open. Alternatively, even if they are completely closed, a buoyant object could be attached to a part of the blade, causing it to slightly open due to buoyancy in a specific orientation. Air could enter and push the blades open, or plates could be attached to specific parts of the tank to facilitate the collection of air around the blades of the water turbine, thereby controlling the flow of water and air. This blade shape is suitable for tunnels or other places where there is no energy for air or other gases to rise, and when this type of water turbine is installed under water pressure, the blades will open where they are pushed by the water flow and close when the pressure of the water flow weakens. In large-scale hydroelectric power plants such as dams, there are some with a drop of 100 meters and pipes hundreds of meters long, but if the hydroelectric propeller is only attached to the downstream part, the energy of the water flow cannot be sufficiently recovered to rotate the turbine of the generator, resulting in losses. Therefore, the drop should be around 10 meters, and the energy should be distributed through narrower pipe-like tunnels or tubes, or water turbines or hydroelectric propellers should be installed in sections where there was previously only water flow. This allows for the efficient recovery of the potential energy of the water flow.Furthermore, when compressed air or similar substances are ejected from a deep location with high water pressure, and the water turbine is rotated by the upward force of the air, if the water tank is designed in a way that the compressed gas is ejected at approximately the 1 o'clock position when the water turbine is rotating clockwise, the deceleration of the propeller and water turbine due to water pressure can be suppressed. Since compressed gas is also ejected from the 6 o'clock position, a constant clockwise rotational force is maintained, converting the energy of the compressed air or gas, as well as the buoyant force due to the density difference, into rotational energy for the water turbine. When injecting compressed gas into a hollow shaft of a water turbine or similar device, various methods can be employed. For example, a latch could be placed at the 1 o'clock or 6 o'clock position to catch the shaft's opening, allowing the gas to escape. The opening would then close with a spring or similar mechanism when the shaft reaches a position where there is no longer a latch. Alternatively, gas could be passed through the hollow section of the shaft and covered with a metal cap. When a specific part of the cap is open, the gas can be released when the rotating shaft's gas outlet reaches a specific position. Another method involves controlling a valve to synchronize the release of compressed gas with the position of the water turbine, ensuring that compressed gas is released only when the turbine reaches a specific position. The shaft that transmits energy from the water turbine could be extended horizontally to enhance airtightness and prevent water from leaking out of the tank, or it could be temporarily rerouted using gears within the tank to change direction and transmit rotation to an upward-extending shaft. Once the shaft reaches a height where it can come into contact with the outside air at the top of the tank, the energy could be transmitted back to the gears to create a power source. Waterwheels and similar devices can be installed by connecting multiple units vertically. Various methods are possible, such as extending tanks deep underground or raising them above ground. To transmit the upward energy and buoyancy of air or other water sources as power, a structure can be used in which the water is connected by belts or similar devices and supported in several places (similar to a bicycle chain, with plates whose angle can be changed by the resistance of the buoyancy (although the angle of the plates does not necessarily have to change due to resistance, considering installation costs)). Furthermore, the energy obtained by buoyancy using this method can be connected by a shaft and used as upward kinetic energy to lift water, etc., for pumping purposes.These can be divided into sections of 10 meters or so, and multiple units can be connected vertically to adjust the water pressure. Air can be reused by using a structure that allows it to flow again from the lower structure to the upper structure via pipes, etc., and the upward energy of the injected air can be efficiently utilized. The energy associated with the rising air in each structure can also be converted into driving energy by shafts, etc. Water can be pumped up from the point where the air rises and comes into contact with the ground or other atmosphere. A similar structure, like a bicycle chain, can be used to transport water upward along its rotation. By stacking multiple such devices vertically, the upward energy of air (or carbon dioxide, etc.) can be efficiently utilized and converted into energy, and the water pressure can also be controlled. The air can be collected in a tank or similar container and reused without being released to the outside. After compressed air is introduced, covers can be attached to the contact surface with the atmosphere to prevent leakage, and if necessary, pipes can be installed to release the compressed air into the atmosphere. Pressure sensors can be installed along the path connecting compressed air, etc., and valves that open and close in conjunction with these sensors can be attached to optimally control the pressure at each point where air flows. The valves that open and close can be electronically controlled or analog, such as springs that open and close according to the pressure. The device can be connected horizontally instead of vertically, and can be made in a small size. Of course, such a device can be attached to ships, etc., to provide propulsion. To utilize energy efficiently, water, etc., can be moved to a high position such as 60 meters above the ground using methods involving buoyancy as described above, such as water pumps, elevators, or vehicles, and then the direction of pipes, etc., can be turned downwards to let the water fall, and the kinetic energy of the water at the bottom can be used to power propellers for power generation, etc. Of course, this energy can be used in various ways as power. If such a device is installed on a ship, it can be used to generate electricity or as a direct source of propulsion energy. Even without using pipes, a certain amount will fall to a limited point. This can be pumped up using the principle of this device. Since the kinetic energy increases in proportion to the square of the speed of movement of the object, energy can be obtained efficiently.At a height of approximately 60 meters, the kinetic energy is approximately 625 times greater compared to a speed of 1 m / s. Even at 40 liters per second, considerable power can be generated. Energy is efficiently increased by the vertical fall of water or other materials. The energy of moving matter is efficiently increased and used to power generators, etc. (for example, to rotate turbines for hydroelectric power generation). Even a baseball filled with iron would work. When transmitting energy from multiple balls to, for example, a turbine for power generation, the balls can roll on rails to fall into pipes at a higher position in a regular pattern, and the flow can be controlled with stoppers that can be opened and closed. By making them ball-shaped and providing a slight incline, they can be easily moved by gravity without any power source. Multiple pipes are prepared for the balls to fall into, and each turbine that receives the energy can independently transmit the energy from the balls. For example, instead of having blades for a water wheel in a single row, the positions of the blades can be slightly staggered to efficiently transmit the energy from the balls to the wheels, water wheel, turbine, etc. The movement of the ball, controlled at the upper drop position, and the rotation of the turbine, etc., below are mechanically adjusted and controlled so that they can be collected at the upper position for maximum efficiency. If it is water at the lower position, the water can be collected in a certain place, and if a mechanically moving bucket or similar device moves upward from there, the water will move upward. If a ball-shaped object is moved to a certain place by gravity, etc., or its direction is controlled by lanes, etc., the ball will move upward in accordance with the movement of the machine, like a batting machine. To maintain strength, the ball can be covered with impact-resistant material such as rubber or leather. When setting up, for example, natural terrain such as mountains and valleys can be used, and if there is a spring, it can be used, which can reduce the cost of building a large-scale facility from scratch. Existing buildings can also be used, or parts of them can be modified. If a certain amount of spring water is gushing from near the top of a mountain, etc., that water can be drawn up to a specific point while maintaining altitude using pipes, etc. If the amount of water is small, it can be pumped up using power and transported from below for reuse.Even if there is a 50-meter difference in elevation between the mountaintop and the surrounding lowlands, the mountain's original altitude means that only the 50-meter section needs to be maintained, which can reduce the need for scaffolding. Mountains are also often places where people don't normally go, making it easier to install pipes. It's also possible to create supports for pipes using scaffolding made of wood or concrete. Hydroelectric power generation, such as dams, stores water that has flowed down from the surrounding mountains and uses the elevation difference between that water and the water channel below to generate energy, but it is also possible to obtain high energy while keeping construction costs down by utilizing the topography of the mountain itself. By excavating the lowlands and placing generators underground, noise can be avoided and the elevation difference can be widened. When dropping water downwards through pipes for power generation, it is possible to connect pipes to the top of the pipes to supply compressed air to make the water fall more quickly, or instead of a single pipe, a structure can be created by bundling multiple thin pipes together, and multiple ventilation holes can be made in the inner pipe of the bundle to supply compressed air from the top of the pipe, allowing the water to fall smoothly through the pipe. If there is no spring water, a certain amount of water can be transported or rainwater collected and used. Vehicles can also be efficiently moved using structures that slide on the cooled ice mentioned above. If rails are constructed to move the vehicle upwards after accelerating it to a certain extent using gravitational energy or an engine, the energy required to move the water to a higher position can be obtained through acceleration due to gravity, thus reducing the energy cost of propulsion. Of course, such devices can also be attached to ships to provide propulsion. Taking advantage of the natural principle that the temperature around 5 meters underground in mainland Japan is maintained at about 15 degrees Celsius throughout the year, a tube-shaped tunnel can be laid down there to save energy on cooling. Alternatively, when laying this structure on the surface and cooling it, it is possible to cover the outer circumference of the tube with liquid water, and if the outer circumference of the tube is made of a light-transmitting material such as plastic or glass, the scenery can be seen from inside the vehicle.Similar systems can be used to run ships or other vessels in tunnels filled with water or other fluids, creating a vacuum inside the tunnel to improve energy efficiency during travel (this can be applied to anything that can travel through a tunnel). Even vehicles like cars can use a similar structure to reduce energy costs, not just large vehicles like trains. This can also improve the reliability of autonomous driving systems. Vehicles can be connected to trolleys or similar platforms, with the weight of the vehicles primarily supported by the sleds to reduce rolling resistance. Even on existing roads, to prevent freezing and lower road surface temperatures in summer, water can be circulated through pipes in tanks installed 5 meters underground beneath roads and walkways, reaching approximately 10 centimeters below the asphalt surface. This prevents the road surface from freezing or overheating. Circulating water can also be routed around the sleds through pipes. This can also improve cooling efficiency, especially during the summer. Use plastic bottles to create a space the size of a futon (it can be larger or smaller, the size can be changed) and maintain a temperature that is cool in the summer and warm enough not to freeze in the winter. Water from a tank installed about 5 meters underground is poured into the plastic bottles through pipes and connected so that the water circulates and returns to the tank. To make an emergency stop for trains, install pipes under the train tracks and pour oil (or clay, or any gas) into them. Then, make a hole in the top of the pipe and drop something like a stake from the train into it to catch on it. Where the stake falls, it will come into contact with a round plate made close to the edge of the pipe to prevent pressure from escaping, like an air gun, increasing the pressure inside the pipe and slowing down the train. If multiple pipes are installed and there are also multiple stakes for the train, the braking force applied to the train can be adjusted by first attaching one stake (a rod-shaped object used to hook the train to the outside, etc.) and then attaching a second, third, and so on. Holes can be made in various places in the pipes to release pressure, and when a certain pressure is reached, the stoppers will come off, preventing the pipes from breaking due to sudden pressure buildup. Similar to how solar panels are cooled, a series of such structures made of connected plastic bottles can be lined up on the roof of a house, and water can be introduced into or stored in them to control the temperature inside the house. The water can be circulated from tanks installed about 5 meters underground where the ground temperature is around 15 degrees Celsius throughout the year. The flow of water can also be stopped for a certain period of time, such as when the temperature changes on the roof. Structures made of plastic bottles (or other materials) can also be designed to be embedded under roof tiles. By preparing multiple underground tanks and connecting them at different depths, it's possible to precisely adjust the temperature. If natural cold spring water or hot spring water is available, it can be directly pumped into the structure. In winter, it can prevent snow from accumulating on the roof. Also, by running water over the structure, the exterior can be cleaned.This method utilizes the fact that the temperature at a depth of about 5 meters underground remains around 15°C year-round, or by taking advantage of the fact that the temperature changes depending on the depth underground. On mountain slopes, the depth is determined according to the required ground temperature, such as about 5 meters underground or a slightly shallower depth, and a structure is constructed in which water or other liquids are pre-filled into tanks made of plastic bottles, etc., to control the temperature of the air, etc., as described above. The plastic bottles are constructed with spaces inside that allow air to pass through, and the temperature of the air can be controlled by the air passing through these spaces. This air is then connected to a space above ground, also made of plastic bottles, where plants are grown, through pipes made of plastic bottles, etc. Outside air is taken in through a specific intake and circulated to the underground space and the space where plants are grown. Outside air can be blocked and a special gas can be circulated, or the air can be purified by using an air filter at the outside air intake. The underground tank section can be made into multiple sections, some at high positions and some at low positions relative to the structure for plant cultivation, etc., taking advantage of the difference in altitude of the mountain. By using the temperature difference with the outside air, natural convection can be created, reducing the cost of air circulation. If necessary, fans powered by motors can be installed to direct air into the space where plants are grown. The plant cultivation space can be designed to be so narrow that it is impossible for a person to stand and walk through, maximizing the use of space. Pallets with plants set on them can be placed on carts and moved in and out of the cultivation space using wheels or rails. Instead of sunlight, LEDs or elements that convert heat into light (announced by Kyoto University, etc.) can be used, or sunlight can be drawn into the plant space using mirrors or optical fibers. If the heat applied to the conversion element affects the plants, pipe-like devices can be set up in between and water can be circulated through them to cool the plant cultivation space. Also, since the area around the plant cultivation space is originally constructed with plastic bottles, etc., water at a constant temperature, such as from 5 meters underground, can be circulated through it to prevent excessive temperature fluctuations.In a system that utilizes underground temperature, air regulated by the underground temperature can be circulated from the underground space to areas for plant cultivation, etc., and water stored about 5 meters underground, which is also regulated to about 15 degrees Celsius, can also be circulated. The plant cultivation space can be made large enough for a person to enter, or it can be used for purposes other than plant cultivation. The plant cultivation space is separated from the outside world by a structure made of plastic bottles, etc., and in order to control the temperature and humidity inside, air regulated by the ground temperature is moved from the underground structure that utilizes the ground temperature to the plant cultivation space through pipes, etc. At that time, it is possible to move only air, or water is moved along with the air, and the water can be continuously flowed into the juice compartment of the plastic bottle, which can also be used to control the temperature of the plant cultivation space. In some cases, only water or only air can be circulated. If the plant cultivation space is designed to be long and narrow, too narrow for a person to enter, the space can be used effectively, and multiple plant cultivation spaces can be stacked on top of each other. The plant cultivation area can be moved from the work area where people tend to the plants through a long, narrow tunnel-like structure made of similar plastic bottles, either underground or above ground, using rails or something similar to pull the plants on a trolley with an electric tow truck or winch. The work area can also be sealed off from the outside world to prevent bacterial intrusion and seed cross-pollination. The size of the plant cultivation area can be adjusted to accommodate human activity, and a solar power generation system can be installed to control the temperature of the solar panels for efficient power generation. These inventions will be used to contribute to a society where goods and services can be exchanged in a way that facilitates communication. To build a rational society based on these inventions, services will be mutually shared, and the right to operate the service network will be entrusted to the inventor by contract, with the inventor managing it.As an application of the method described above, which involves dropping water or other liquids vertically to power generators below, instead of water, magnets or other objects modified to roll can be dropped. Coils can be placed around the path of the falling object to generate electricity, and the object can roll along the path using gravity energy to reach a certain point. Then, using compressed air or other power sources as described above, gears and shafts can be driven by the movement of gears, etc., to bring it back to the upper position. Once it reaches the upper position, gravity energy can be used to roll it along the track to a downward-facing track, and it can then fall again. A certain amount of space can be provided at the top or near the drop point to store the rolling magnets or other objects, and they can be controlled by electrically operated stoppers. When the stoppers are released, gravity will allow them to roll along the rails again. This can also be done with devices that generate electricity by dropping water or other liquids vertically and transferring that energy to the blades of a generator below. Tanks can be installed at the top or bottom to store water, and the stored water can be dropped as needed to generate energy. Natural water can also be stored there, or spring water can be used. Various types of pumps can be used to power the water to the top. When connecting plastic bottles and flowing temperature-controlled water from an underground tank into them to control the temperature of a space inside, the space per unit area can be increased by creating a multi-tiered structure of these plastic bottles in an upward direction. This space can be used as a plant cultivation space, and it can be connected to a workspace (where manual work such as thinning is done, if it is located below the cultivation space) by using rails or spiral tracks to extend down to the bottom. Plants and the carts they are on can be moved from a high place to a low place using elevators or similar equipment. Elevators and other similar systems also have rails, and these rails can be easily rerouted or rearranged like a puzzle, allowing their direction to be freely changed.Elevators can reach the edge of the cultivation space, and chairs can be placed on the elevators so that they stop at each floor. Rails on the elevator can be connected to rails in the cultivation space, and plants can be moved using carts to the area around chairs where people are sitting. People can work while seated. The interior of this tall, multi-tiered structure can be sealed by enclosing it with light-transmitting vinyl or similar material. A simple, single-tiered structure can be easily sealed by covering it with a structure made of vinyl or similar material, and multiple airlocked doors can be installed at the entrance to completely block out the outside world. The interior of a structure made of plastic bottles can also be sealed by sealing it to prevent outside air from entering. Elevators can also be installed inside the space of a sealed structure. Since the plants inside are isolated from the outside world, seeds will not get mixed up, and insects will not come. When creating a structure by processing and connecting plastic bottles, etc., and placing plants inside to grow them, the structure can be enclosed with light-transmitting vinyl or similar material to isolate it from the outside world. When a person needs to work near the structure, parts of the plastic bottle structure can be moved to allow access to the interior space. After work, the structure (parts, etc.) made from the processed plastic bottles can be returned to their original positions. If the structure constructed from plastic bottles is used to isolate the interior from the outside air and cultivate plants, carts can be used to move the plants. These carts can be connected in a train-like fashion with chains, and powered by winches or by having some of the carts powered, using tires or rails. To efficiently capture sunlight into the space, methods such as transmitting sunlight using light-gatherers (sunflowers, etc.) or fiber optics, or linking the light to the desired space with movable mirrors that can change angle, or a combination of these methods can be used. The device labeled R, circled in the diagram, is a concept that includes at least the functions listed below from "1" to "7," as well as some, all, or part of other functions. "1" Water (liquids such as liquid metals and liquid mercury can also be used).) The difference in gravity between water and air (gas, etc.) is used to generate upward energy inside the tank.2) The upward energy generated inside the tank is converted into rotational energy by a device with movable vanes, etc., and a bicycle chain-like and crank-like mechanism is connected in principle.3) This device for transmitting rotational energy is installed inside the tank. (Supported by pillars, etc. to prevent wobbling)4) Water, etc. (liquid, etc.) is added to the tank from the outside using pipes, hoses, etc.5) Compressed air (gas, etc.) is added to the tank and ejected through pipes so that it hits the vanes of the rotational energy transmission device, while the pressure is controlled by a sensor. This function can also be performed using industrially produced gases such as hydrogen instead of compressed air.6) Water (liquid, etc.) is dropped downward from the top to the bottom using pipes, etc. This energy can be used to power a generator (to turn gears, etc.) or as another energy source. This energy from the water, etc. can also be used to power a device for compressing air, etc. This energy can also be used to power an electrolysis device for producing hydrogen, etc. "7" The water that went down. Liquids are stored in tanks and other containers, and the difference in gravity between the liquid and gas is converted into rotational energy to propel them upwards for reuse. Liquid metals such as mercury can also be used as the liquids to be dropped. The entire apparatus can be sealed with strong walls to create a vacuum and eliminate air resistance. To efficiently produce compressed gas, a cylindrical tube and a device that acts as an efficient stopper, moving from top to bottom inside the tube and compressing the gas without leaking air, are used. This wire-like device is surrounded by a rubber ring-like section that can be sealed tightly by air pressure, preventing air leakage. To improve lubrication, lubricating oil can be sprayed around the moving part of the rubber ring-like section using a nozzle extending from inside the stopper. A tank or other container is placed on top of this stopper-like device and filled with heavy objects such as water to move it downwards, or a wire or winch is installed to move the stopper-like device upwards. A chain can also be connected downwards, and in a situation where gas cannot enter or exit via water, etc., it can be connected to an external gear, etc., and water, etc. (liquid, etc.) can be dropped from above through a pipe, etc., and the energy from this will rotate the gear and pull downwards a device that acts as a stopper. When moving this stopper-like device upwards from below, the air inside a rubber float-like object can be deflated to release contact with the cylindrical pipe and lift it up smoothly, or the water, etc. used as a weight can be drained by opening the tank door or valve below and moved to another tank, etc., using a pipe, etc. This water can be reused by converting the difference in gravity between liquid and gas into rotational energy to bring it upwards and return it to an upper tank, etc. To eliminate air resistance, the pipe through which the liquid, water, etc., or liquid metal falls can be depressurized or made into a vacuum. To achieve this, if there are pipes through which liquids or other fluids pass, or devices that use the force of that flow to generate power, such as turbines in power generation equipment, these devices can be covered with a strong material, such as steel, to maintain a vacuum or reduced pressure state. Within this cover, the movement of liquids and, for example, the power generation equipment, can also be kept in that vacuum or reduced pressure state.A structure that is isolated from the outside, like a submarine, is created, and piping and power generation equipment are placed inside. Then, a single pipe is installed that allows ventilation to the outside, and air is sucked out from there using a compressor or similar device, creating a vacuum or reduced pressure state in the area where people and internal equipment are located within the submarine-like structure. Of course, a refrigerant (such as fluorocarbons used in air conditioners or their substitutes like HFCs) can be used in the gaseous part (the principle of obtaining rotational force from a device that converts the difference in gravity between gases and liquids into rotational force, such as a vane installed inside a tank, etc., using a bicycle chain-like device). For example, the refrigerant can be compressed and guided through pipes to directly transmit energy to the vane, etc., which converts it into rotational energy. Alternatively, the compressed refrigerant can be passed through pipes inside a tank, etc., containing a liquid such as water, where heat exchange takes place and the heat is exchanged with water, etc. (any shape that can act as a heat medium is acceptable) using the principle of a heat pump, or it can be exchanged with air, etc., that has been introduced from the outside through another pipe. Then, the compressed refrigerant, having released a certain amount of thermal energy, is released while being controlled by a valve at the bottom of the vanes or other parts to convert the pressure into rotational energy. As a preceding process, like an air conditioner, the heat of vaporization of the refrigerant can be used to exchange heat with the air, for example, by piping outside air through pipes near the pipes containing the refrigerant. When the compressibility of the refrigerant decreases, heat exchange occurs with the surroundings, and the temperature of the surrounding objects decreases. If the tank containing the device that converts to rotational energy is filled with water (liquid, etc.), the temperature of this water will decrease due to the action of the refrigerant. If this device is installed at a depth of about 5 meters underground in the mid-latitudes where the annual ground temperature is stable at about 15 degrees Celsius, the water (liquid, etc., regardless of shape or form, as long as it does not react easily with the refrigerant) that has lost heat from the ground can be balanced by the addition of geothermal heat from the surroundings.When the internal temperature of a device that extracts rotational energy drops significantly due to heat exchange with a refrigerant, for example, a tank is installed at a point 5 meters underground where the temperature is maintained at around 15 degrees Celsius year-round. Water (or any liquid that does not react easily with the refrigerant, regardless of its shape or form) is placed in the tank, and the temperature of the water inside is controlled by geothermal energy (the ground temperature fluctuates with the seasons depending on the depth, but the property that underground it is inversely proportional to the change in ambient temperature allows for stable intake of thermal energy, so the depth at which the tank is installed can be freely changed). The device that obtains rotational energy is connected to the tank inside the tank via pipes, and the cooled water is put into another tank installed underground, or the replaced water is put into a tank installed at around 5 meters underground and heated and maintained by geothermal energy. Pipes can be installed inside the tank containing the cooled water, and warm outside air can be introduced to raise the temperature of the water inside the tank. Alternatively, the outside air that has been cooled by heat exchange can be sent to a space above ground using a pressurized fan via pipes for use as an air conditioner. Alternatively, if water maintained at a temperature due to the above-mentioned geothermal temperature is circulated around a tank or similar container containing a device that extracts rotational energy using pipes, the heat absorbed by the refrigerant can be replenished. The refrigerant (gas, etc.) that has reached the top of the tank moves sequentially through pipes to a device with internal blades or other components that convert it into rotational energy, while the pressure is regulated by control valves and pressure sensors. The refrigerant is then recovered and reused through pipes back to the initial compression device. Another method is to use the principle of a solar water heater, which collects solar energy using a concentrator and converts it into thermal energy for water, by heating water (liquid, etc.) to the highest possible temperature and introducing it through pipes into a tank containing a device that extracts rotational energy, and then introducing a refrigerant (carbon dioxide, etc.) whose temperature has risen due to compression. This causes the water (liquid, etc.) in the tank to boil, and the resulting force moves the blades or other components of the device that extracts rotational energy. Heat can also be obtained from solar energy (sunlight, etc.), magma, geothermal energy from naturally occurring hot springs, etc.A device similar to a solar water heater that uses the sun's heat to heat bathwater can be filled with water, or instead of water, a substance with a high boiling point (fluorine point), such as sodium, and heated to a high temperature to power a device (such as the circled R in Figure 8) that converts that heat into rotational energy. When guiding thermal energy to a device like the circled R using this mechanism, the sodium can be heated to a high temperature to transfer that energy to water passing through pipes, or the sodium (high boiling point substance) can be moved directly through pipes. When high-temperature sodium (high boiling point substance) is guided (moved) through pipes into the space containing water (liquid, etc.) in the tank of the device like the circled R, the heat causes the surrounding water (liquid, etc.) to boil. The heat-transmitting substance such as sodium can be recovered through pipes into a tank and reused. This can be done using a motor-driven pump. The steamed water (liquid, etc.) can also be moved through pipes into a tank and then returned to the tank in the device like the circled R using pipes. Installing tanks and other containers in a location such as 5 meters underground where the temperature is maintained at around 15°C to 17°C year-round can make it easier to control the temperature of the tanks and other containers. It is also possible to use the energy of a device like the one circled R to activate the refrigerant. One method is to guide or recover the high-temperature refrigerant as a gas directly into a device like the one circled R containing water or other liquids, using pipes, etc., while controlling the flow with pressure sensors and valves. Alternatively, the high temperature of the refrigerant can be used to flow through pipes, etc., to heat the water or other liquids in the device circled R, causing them to boil, and then using that to convert (generate) rotational energy. By using the relationship between the state of matter and heat in the three states of matter, pathways can be created that allow a substance to change its state using natural energy, and this can be used to operate devices like the one circled R that convert the state into rotational energy, or to cool other things (such as air conditioners), heat other things (such as heaters), or boil water with a heat pump.A device shaped like an R enclosed in a circle can generate rotational (driving) energy, which can be used to pump water or other liquids from below to above (the rotational energy can move belts, etc., to fill attached buckets, etc., with water or other liquids, thus pumping or moving substances). It is also possible to move water or other liquids from below to above, against gravity. When water or other liquids are dropped downwards, their kinetic energy increases due to gravity, and this energy can be used as an energy source for hydroelectric generators or for various other energy applications. When an air conditioner is operating as a heater, heat exchange by the refrigerant becomes difficult in the cold winter. Therefore, liquids (water, etc.) stored in tanks located 5 meters underground or elsewhere, where the temperature is maintained at around 15°C to 17°C year-round, are circulated through pipes around the outdoor unit of the air conditioner and the heat exchange area. This allows the refrigerant to exchange heat at a temperature higher than the cold winter outside air. Pipes for water can be installed around pipes for refrigerant, and the water can be collected and reused in tanks installed 5 meters underground (multiple tanks are also acceptable; the temperature inside the tanks can be controlled by connecting them with pipes, etc. Multiple tanks can be installed at different depths). The water can be moved using natural elevation differences or pumps. Since it is said that the battery life of smartphones and other devices is best when the battery level is between 20-80%, a battery with a control function that can automatically set the charging timing in that range is used. The smartphone and other device are linked to this charging device via Bluetooth® or a USB cable, and data such as the battery level is read from the smartphone's control program, allowing for automatic control of the start and stop of charging linked to the freely set battery level. In winter, electric assist bicycle batteries may not produce sufficient output due to the cold. Therefore, attach a heating device such as an electric foot warmer around the battery and switch the heating device on and off according to the battery's temperature.When the electric assist bicycle's battery level is low, the circuit is set to cut off the power to this device. When keeping cattle in a space inside a structure made by processing plastic bottles, as shown in Figure 1, etc., to separate and recover methane gas from the cattle's burps, etc., if the cattle are in the lower part of the space, the space is constructed in multiple stages and the spaces are connected by pipes, and the methane gas accumulated in the upper spaces is separated and recovered by the device. The inside of the space is sealed, so it does not mix with outside air naturally. Compressed air (gas, etc.) or refrigerants (such as Freon or substances with similar properties) are passed through pipes to a device like ▲R▼ that allows outside air to be brought in through a deflection valve or pipe with an air filter, etc., and water (liquid, etc.) is in the tank, etc. (even if there is no liquid substance, if high-pressure gas is blown out in a certain direction, the force is converted into rotational energy by the blades of the device ▲R▼. (It can be used as a power source for movement, etc.) When sending it to a place to convert it into rotational energy, for example, a refrigerant (such as Freon or equivalent substances) will become hot due to pressure changes or conversely, its volume will suddenly increase and it will become cold due to pressure changes, and the principle of an air conditioner or heater can be used to generate electricity while obtaining a heat source, or conversely, to cool the surrounding objects. Substances that do not easily vaporize, such as sodium, can be sent to the ▲R▼ device via pipes, etc., to boil water in a tank, etc., and convert it into rotational energy. To lower the resistance of a chain with rotating blades, etc., that moves from top to bottom, cold water at about 15°C can be passed around the chain moving downwards via pipes, etc., and through a tank, etc., so that the boil around that part is contained, and the chain can move smoothly. Of course, it is also possible to set up tanks or similar devices at a depth of about 5 meters underground, where the temperature is maintained at around 15°C throughout the year, to store water, and then guide it through pipes or similar devices into the ▲R▼ device without mixing it with the water in the tanks, and circulate it. If there is water in the tank of a device like ▲R▼, when pumping air into it, it is also possible to set up filters or similar devices at the point where the air and water meet in the pipes, etc., that have the function of separating what can pass through and what cannot, depending on the properties and characteristics of the material, in order to send the air from the pipes to the water more stably. As for the function of the filters, for example, if a filter is placed between pipes, it is possible to use filters that have the function of allowing material to move from left to right, but preventing material on the right from moving to the left, or filters that have the function of allowing air to pass through but not water, depending on the properties and fineness of the material that can pass through the filter. Filters, etc., can be attached, for example, to the location marked ▲F▼ (Figure 8). ▲F▼ can be installed wherever and as needed, such as on pipes. The letters enclosed in ▲ and ▼ in ▲F▼ mean they are enclosed in a circle. In this case, it means an F enclosed in a circle. The same applies to other elements.Heat can be obtained from sources such as solar energy (sunlight, etc.), magma heat, and geothermal heat from naturally occurring hot springs. The device, similar to a solar water heater that uses solar heat to heat bathwater, can use water as its primary energy source, or it can use rotational energy (like ▲R▼ in Figure 8) to power another device. When guiding thermal energy into a device like ▲R▼ using this mechanism, sodium can be heated to a high temperature to transfer its energy to water passing through pipes, or the sodium can be directly circulated through the pipes. When high-temperature sodium is introduced through pipes into the tank containing water (or other liquids) in a device like ▲R▼, the heat will cause the water to boil. Heat-conducting materials like sodium can be collected and reused in a tank via pipes. This can be done using a motor-driven pump. The steamed water can also be moved through pipes to a tank and then returned to the tank of the device like ▲R▼ using pipes. If tanks are installed in a location such as 5 meters underground where the temperature is maintained at around 15°C to 17°C year-round, it can be easier to control the temperature of the tanks. It is also possible to activate refrigerants as energy for devices like ▲R▼. One method is to guide or recover high-pressure refrigerant as a gas directly into devices like ▲R▼ containing water (liquid, etc.) through pipes, controlling the pressure using pressure sensors and valves. Alternatively, the high temperature of the refrigerant can be used to flow through pipes, thereby heating the water (liquid, etc.) in a device like ▲R▼, causing it to boil, and converting that into rotational energy. By using the relationship between the state of matter and heat in the three states of matter, pathways can be created that allow a substance to change its state using natural energy, and within these pathways, devices like ▲R▼ can be used to convert energy into rotational energy, cool other things (such as air conditioners), heat other things (heaters), or boil water with heat pumps.A device like the one shown in ▲R▼ can be used to obtain rotational energy and use it to pump water or other liquids from below to above (by using rotational energy to move a belt or similar device, which can then pump water into attached buckets or other containers). This allows water or other liquids to move against gravity from bottom to top. When water or other liquids are dropped downwards, their kinetic energy increases due to gravity, and this energy can be used as an energy source for hydroelectric generators or for various other energy applications. When an air conditioner is operating as a heater, especially in winter when the outside air is cold, heat exchange by the refrigerant becomes difficult. Therefore, water stored in tanks located 5 meters underground or elsewhere, where it is kept at a constant temperature of around 15°C to 17°C year-round, can be circulated through pipes and guided around the outdoor unit of the air conditioner and the heat exchange area. This allows the refrigerant to exchange heat at a temperature higher than the outside air in winter. Pipes for refrigerant and pipes for water can be installed around the pipes through which refrigerant flows. The water can be collected and reused in tanks installed 5 meters underground (multiple tanks are also acceptable; the temperature inside the tanks can be controlled by connecting them with pipes. Multiple tanks can be installed at different depths). The water can be moved using natural elevation differences or pumps. Since it is said that the battery life of smartphones and other devices is best between 20-80% battery level, a battery with a control function that can automatically set the charging timing within that range is used. This charging device is linked to a smartphone or other device via Bluetooth or a USB cable, and battery level data is read from the smartphone's control program, allowing for automatic control of charging start and stop based on the freely set battery level. Electric assist bicycle batteries may not output power properly in the cold winter, so attach a heating device such as an electric foot warmer around the battery and switch the heating device on and off according to the battery temperature. Set the circuit so that the power to this device is cut off when the electric assist bicycle battery is low.When keeping cattle in a structure constructed by processing plastic bottles or similar materials, as shown in Figure 1, methane gas from the cattle's burps is separated and recovered. If cattle are in the lower part of the space, the space can be constructed in multiple stages, with pipes connecting the sections to separate and recover the methane gas accumulated in the upper sections. The inside of the space is sealed, so it does not naturally mix with the outside air. Outside air can be introduced through a ventilating valve or a pipe with an air filter. ▲R▼ means an R enclosed in a circle and is used in Japanese patents. As explained in Figures 10 and 11, a rotating ring shape is created using parts such as bicycle cranks and gears, and the function of the chain that transmits their rotation (a belt or other similar function would also work). The chain is then connected to a bucket, so that when the chain moves, the bucket also moves in conjunction. Assuming a height difference of about 60 meters between the high and low parts of such a structure, a tank or similar container can be installed that can collect water, mercury, or other fluid substances by slightly touching the area where a bucket passes when it reaches the higher part, causing the bucket to tilt and drop out. Rotational force is then applied to the crank or gears of this device using an electric motor, waterwheel, or other power source, causing it to rotate. A tank for storing water, mercury, or other liquid substances (highly fluid) is provided at the bottom of this device, and as the bucket passes through it, the water or mercury fills the bucket. Alternatively, water, mercury, or any fluid substance with a high specific gravity (such as water or mercury) can be moved through a pipe somewhere along the rotating passage, and the water or mercury coming out of the pipe can be used to replenish the bucket, similar to how water from a tap is used to fill the bucket. The structure can also be designed so that water or liquid mercury falls downwards from a tank or similar container at the top using a pipe, and is collected in the bucket. Buckets and similar objects experience downward kinetic energy, which is further influenced by gravity depending on the distance they fall. The distance from the tank above can be changed by altering the distance between the bucket or object catching the fall.If this chain rotates at a speed of approximately 2.2 meters per second, with 60 buckets attached at roughly equal intervals, and the length of this chain is approximately 132 meters, then the buckets will be filling the upper tank with water or other liquid mercury every second. Assuming that water or other liquid mercury is added to each bucket by the lower section or a replenishment device to a capacity of approximately 40 liters, then 40 liters of water or mercury will be transferred to the upper tank every second. If 10 liters are dropped from the upper tank into each bucket every second, and the buckets catch the liquid, and the distance from the upper tank to each bucket is 15 meters, then the calculated kinetic energy would be 2250 joules. This means that roughly that much downward force is acting on the chain. Even if the output of the drive motor that initially rotated the device is reduced, the rotating device can still move by gradually decreasing the output of the drive motor, as the downward kinetic energy of the water or other liquid mercury is transmitted to the chain in this way. Kinetic energy is calculated as 1 / 2 × mass × velocity squared, so if the velocity increases tenfold, the kinetic energy increases a hundredfold. The amount of liquid mercury, such as water, dropped from the upper tank of this device to the buckets below can be adjusted by valves, and the circumference of the device itself can also be freely changed. Therefore, the values ​​at each part can be varied to optimize the process for the purpose, in order to move the water, etc., from the bottom to the upper tank as efficiently as possible. Resistances that hinder rotation, such as the process of scooping liquid mercury, such as water, from the lower tank into buckets, can be minimized by designing the passage of the buckets to be as efficient as possible. The liquid mercury, such as water, in the upper tank can then be dropped 60 meters down using pipes, etc., and the energy can be transferred to a water wheel or similar device to power a generator. The outside of this device can be enclosed with a shield, and the air inside can be sucked out with a suction device to create a vacuum or low-pressure state inside, eliminating or reducing air resistance when the water, etc., or liquid mercury falls. Such devices serve to transfer gravitational energy into rotational energy via a medium such as water or liquid mercury. Of course, the upper tank can also be used to move water or liquid mercury using energy from conventional methods such as water pumps or waterwheels that rotate by receiving the flow of a river.To drop water or other liquid mercury (or even iron balls) from the upper tank at equal intervals while controlling the timing, a deer scarer (a traditional Japanese deer scarer, often seen in Japanese gardens and made of bamboo, but also made of metal for increased strength) can be installed between the shut-off valve c1 and the upper tank, so that when 10 liters have accumulated, the deer scarer tilts. Alternatively, a waterwheel can be modified to perform a specific action when a certain weight is reached. The rotation speed of the waterwheel can be controlled by applying a certain load. It is possible to construct a device that operates more efficiently than using a conventional power device. The devices shown in Figures 11 and 12 are applications of the devices shown in Figures 4 and 6. The force acting on substances with different masses per unit volume. The difference in pressure can be used as a power source to move gears and other components, and this energy can be converted into rotational energy or other power sources. Even if such a device is installed in a zero-gravity environment (for example, space), if the base rotates, the tanks containing liquids, dry ice, or gases will rotate as well, and this will give the liquids a mass in a certain direction. In principle, this device can generate energy such as rotational energy, just as it would under gravity. Furthermore, by surrounding the tank with a substance such as liquid, the temperature can be maintained and controlled, thereby adjusting the temperature change inside and outside the tank. Magnets and coils can also be placed around the rotating base using the principles of motor power generation to generate electricity. By introducing a liquid (water, mercury, gases supplied through pipes, or something lighter and more fluid than dry ice) and a solid substance that vaporizes due to the pressure difference (such as dry ice or a substance with a movable chamber) or gas into the tank, for example, dry ice will vaporize into carbon dioxide and move in a certain direction through the liquid, and this energy can be utilized. Multiple tanks can be connected, and carbon dioxide (gas) can be repressurized at a certain point to become dry ice or a liquid. This liquid can then be reintroduced into the tanks using pipes or other means. When pushing solid materials into the tanks, external pressure can be applied as needed. If solid materials are being pushed, a sealed space can be connected to the tanks, and power can be used to physically push them in. In the case of liquids, a sealed space can be created, and the liquid can be pushed in using a pressure pump. For example, if water is used as the liquid in the tanks and dry ice is added, the dry ice will turn into gaseous carbon dioxide in the tanks. This gas can then pass through several tanks, or it can be collected in a single tank using pipes, and repressurized to become dry ice or a liquid again. This is then put back into the inlet of the first tank. The process is then repeated.As shown in Figure 4, by arranging timber and other materials in a manner similar to the three pyramids of Egypt, or by freely creating spaces between them, it is possible to install spaces useful for daily life in valleys and other areas in mountainous regions. This would create a large flat area above, resulting in a vast and effective space. Preserving the timber, which has absorbed carbon dioxide, also contributes to combating global warming. Note that these diagrams of invention examples are just examples, and the size and dimensions can be freely combined as appropriate depending on the purpose. To make it easy and convenient to move electric bicycles and other means of transportation to their destinations, parking and storage locations will be provided near stations, etc. For example, electric bicycles will be available at the parking locations and can be unlocked mechanically. The wheels of the electric bicycles will be locked to keep them in the parking locations, and when a user wants to use an electric bicycle, they can launch a pre-registered smartphone app, agree to the terms of service, and click to start using it, and the linked locking device will automatically unlock, allowing them to use it. A wireless location-sharing device will be attached to the electric bicycles so that the administrator can know their location when needed. The smartphone used by the electric bicycle user and the location-sharing device will be linked wirelessly during use, and if they move a certain distance apart, the device attached to the bicycle will have an alarm function that will notify the user and administrator via email, etc. The location of the bicycle can also be automatically recorded and saved using the device. In the event that the distance between the bicycle and the user's smartphone becomes too great, safety will be ensured, such as by shutting off the motor current in the case of an electric bicycle. In a simpler system, when unlocking the locks securing bicycles in the parking area, the administrator can remotely activate the unlocking device via the internet after verifying the user's identity by confirming a password set in advance, along with the caller ID and name, over the phone. Alternatively, a password valid for a certain period of time can be communicated to the user via mobile phone, and the user must enter the password by pressing the unlock button on the parking space within that time to unlock it. When locking the parking area, the user's identity is verified by entering the password used for unlocking. Other methods include using fingerprint, facial, or eye recognition via dedicated smartphone software for identity verification, or using the video call function of a smartphone to verify the user's face and manner of speaking, allowing the administrator to remotely unlock the device. If the locking device for the parking area and the key for electric bicycles are separate, there is a possibility that only the parking area will be locked while the bicycle itself remains unlocked. Therefore, the electric bicycle's power should be automatically turned off if it is not operated for a certain period of time.The system involves setting a password using RSA encryption technology via computer, sending it to the locking device, and transmitting the unlock code via mobile phone, etc. Alternatively, a program is installed that automatically recognizes a password linked to the time of day, allowing administrators to communicate randomly changing passwords to users via mobile phone or email. The user is responsible for managing and using the bicycle, from the time of application to returning it properly to its storage location with the bicycle locked. The locking device notifies administrators and users via a server when the lock is released or locked. The parking area is equipped with motion-sensing cameras and light communication devices to record and notify administrators. For electric bicycles, the key to lock the tires is linked to the power supply of the electrical system. Users can choose to have multiple locking devices (one on the parking area and one on the bicycle itself) or to have all locks on the bicycle. If all locks are on the bicycle, administrators can safely unlock and lock the bicycle while monitoring the parking area status via video conferencing, live cameras, etc. In the case of multiple bicycles, security is enhanced by ensuring that when the lock is released, the key and battery of the bicycle can be removed when the locking device of the parking space is released. When locking, the key to the bicycle can be returned to the locking device of the parking space, and the administrator can confirm via a signal that the electric bicycle battery is charged. Once the locking device is locked, the key and battery of the bicycle cannot be removed. Even if the devices are installed together on the electric bicycle, the administrator can remotely check and manage the status of the electric bicycle, key, and battery using communication functions. A magnetic card key can be used as a means of identity verification by having the user authenticate it with a machine installed in the parking space, or it can be used in conjunction with the above methods. Payments can be linked to the card key or smartphone and automatically deducted from the bank. If a rain cover is attached to the electric bicycle, it can be used comfortably even in the rain. By connecting materials such as plastic bottles, a space is created for people to pass through, allowing for internal temperature control as they move through. The connected plastic bottles are filled with a liquid (such as water) that maintains a stable temperature throughout the year, typically found at a depth of around 5 meters underground (this is just an estimate). This liquid is then pumped up and circulated through the structure to regulate the internal temperature when the outside temperature is high or low. While groundwater temperature fluctuates annually depending on depth, this fluctuation is also utilized to the fullest extent for climate control. Assuming a natural outside temperature of around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of 15°C water over time. Therefore, to reach approximately 22°C, only about 7°C worth of energy is needed to maintain the air temperature, which is more efficient than raising it from 5°C. The same applies when lowering the temperature. If hot water such as spring water is available, it becomes even more efficient when raising the temperature for climate control. Specialized materials can be used for the plastic bottle-like objects, provided they meet the intended purpose. Installation locations can be selected based on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles are connected to allow water to flow through them. To do this, they are fixed with adhesive tape or similar material and the insides are hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. Plastic objects such as plastic bottles can be made transparent, allowing light to pass through while still creating an open space. If fish are kept inside, it can also be used as art. By changing the size of the space using similar structures, it is possible to fill it with hot water or create other leisure facilities, creating a space that is integrated with nature. It is possible to create a relaxing hot spring without worrying about rain or wind. The temperature inside the space and the temperature of the flowing water are managed by sensors, and the flow rate of electric pumps is automatically adjusted to keep energy costs at an optimal level. If installed in a mountainous area, nearby timber can be used, allowing for effective utilization of the heat generated by burning the wood. Water stored in underground tanks can be flowed through structures made of plastic bottles and then returned to the underground tanks. Electric pumps and other equipment are used to move water and other fluids. The water and other fluids are reused by circulating them in underground tanks and within structures such as plastic bottles.The above-mentioned leisure facilities allow for keeping fish for viewing or fishing. By connecting materials such as plastic bottles, a space is created for people to pass through, allowing for internal temperature control as they move through. The connected plastic bottles are filled with a liquid (such as water) that maintains a stable temperature throughout the year, typically found at a depth of around 5 meters underground (this is just an estimate). This liquid is then pumped up and circulated through the structure to regulate the internal temperature when the outside temperature is high or low. While groundwater temperature fluctuates annually depending on depth, this fluctuation is also utilized to the fullest extent for climate control. Assuming a natural outside temperature of around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of 15°C water over time. Therefore, to reach approximately 22°C, only about 7°C worth of energy is needed to maintain the air temperature, which is more efficient than raising it from 5°C. The same applies when lowering the temperature. If hot water such as spring water is available, it becomes even more efficient when raising the temperature for climate control.

Installation locations can be selected based on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles are connected to allow water to flow. To do this, they are fixed with adhesive tape or similar material and the insides are hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When raising fish in a temperature-controlled space created using such a structure made from plastic bottles, if the fish swim fast, the structure should be as streamlined as possible to allow them to swim in large circles. Setting the width in the direction of travel to 50 centimeters, depending on the size of the fish, will prevent head-on collisions and ensure safety. In addition, by creating a difference in height in such a structure and moving the liquid from a lower position to a higher point with an electric pump, a water flow is created in a constant direction within the space containing the liquid that is in contact with the fish, preventing collisions. The water flow can also be stopped temporarily when necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing geothermal energy, to create a structure where plants of varying sizes are grown. Plants are then planted and cultivated within this structure, and moved to a care area using rails or wheels, maintaining limited and controlled air circulation from the outside world, thereby preventing pollination and complying with plant variety laws. A space isolated from the outside world is constructed using plastic bottles, and this is connected to the plant cultivation area with a hatch. After a person enters and confirms that the space is clean, the connecting hatch is opened, allowing humans to directly care for the plants inside, or to care for them mechanically using robotic arms and remote cameras. Plants transported to the care area via rails can be remotely monitored by cameras, and tasks such as thinning the plants can be automated through AI learning by installed machinery. When using materials such as PET bottles to construct a space, circulating liquids within it and utilizing the temperature of liquids in an underground tank for heating or cooling the space, it is possible to artificially heat (using equipment such as oil boilers) or cool (using equipment such as refrigerators or liquid nitrogen) the circulating liquids. However, it is also possible to use solar heat to heat the space, and the structure made of PET bottles can be used as a solar thermal storage water heater, saving on energy costs. By concentrating sunlight around the structure made of PET bottles, protecting the surroundings with airtight materials such as aluminum, and adding insulation, the heat retention efficiency can be improved. Structures made of materials such as PET bottles can have adequate space inside to grow plants, etc. If water or other liquids are circulated inside the PET bottles and transported via pipes connected to an underground tank, the temperature of the underground will be transferred to the inside of the space. The PET bottles act as a shield, blocking the space between the temperature-transmitting substance such as water and the surrounding space. If you are not pouring liquids that utilize underground temperatures into plastic bottles or similar containers, you can reduce the energy costs associated with artificially regulating the temperature inside the space using air conditioners or boilers by covering the container with a heat-insulating or heat-retaining material.When creating internal spaces within objects made of plastic bottles or similar materials, and the spaces are arranged in multiple levels, if sunlight cannot reach the lower spaces due to objects placed inside the upper spaces, a method can be used to concentrate sunlight at an appropriate position and transmit it to the necessary locations using optical fibers. Alternatively, reflective devices (such as mirrors) can be installed on the sides of the structure made of plastic bottles or other locations where light easily reaches, refracting the light and guiding it from areas with good light to areas with poor light. Since plastic objects like plastic bottles can be made transparent, it is possible to create an open space that allows light to pass through but is blocked, and it can be used as art if fish are kept inside. By changing the size of the space using a similar structure, it is possible to create a space that is integrated with nature by filling it with hot water or other leisure facilities. It is possible to create a relaxing hot spring that does not require worrying about rain or wind. The temperature inside the space and the temperature of the flowing water or other liquids can be controlled with sensors, and the flow rate of electric pumps can be automatically adjusted to maintain an optimal energy cost. If installed in a mountainous area, the heat generated from burning nearby timber can be effectively utilized. By minimizing costs in this way, competitive agricultural products can be produced and then given away free of charge to poor young people, or a coupon-like certificate can be issued based on a set of rules that stipulates the provision of certain services in return. The costs associated with production and services can be significantly reduced, and this can be used as a basis for building a coupon-like concept, perhaps through patent rights. The coupon can also be considered as a concrete entity of the concept. If person A owns an agricultural production site and also owns restaurants and recreational facilities, they could manage the usage fees with such coupons and use them to pay for daily service businesses, inviting participating businesses to join as part of a community-like group. Negotiations could also be made to allow the use of these coupons at restaurants and recreational facilities run by businesses other than A. Both restaurants and recreational facilities can earn money by serving or selling agricultural products as dishes.Even if recreational facilities and similar establishments incur significant labor costs, they can use this coupon if it includes services that fall under such contracts. Efforts should be made to allow the use of this coupon not only for recreational facilities but also for any service industry that normally handles payments in yen or other monetary terms. If person A were the owner and received payment in yen as usual, they would generate income, which the government might collect and distribute to the poor for welfare purposes (such as social assistance). However, by having people like A and others participating in this system handle this role, we can foster a greater understanding of the meaning of receiving services and other fundamental human needs, thereby reducing government taxes associated with such work. This system ensures the securing of food, a basic necessity for human life, allowing people to live on that foundation. If A manages this system, and farmers and service providers join, producers can alleviate concerns about only receiving relatively low-value monetary compensation in the market, and service providers can also find sufficient social significance in this coupon system to justify their participation. This system allows for the creation of a stable society by establishing a system of income redistribution. Furthermore, since this coupon is based on voluntary participation, and participation is voluntary, person A can choose whether or not to allow others to participate if they wish, and can also decide on the terms and conditions of the contract. Person A can decide whether or not to allow the coupon to be redeemed for cash. It is also possible to make it so that it can only be redeemed through person A. Whether or not person A redeems the coupon is at their own discretion. It is also possible to decide that different types of coupons can be exchanged through person A. Person A also has the right to exchange coupons and issue new coupons freely at their discretion. A coupon is a concept. Coupons can be paper-based or electronic. If digitized, the data can be encrypted with PGP encryption, centrally managed in a database, and person A can understand the connections between goods, coupons, and services. Person A is free to decide whether or not to make this data publicly available. Since it is based on trust, interference by third parties is prevented and stability is ensured. When coupons are replaced with cryptocurrency, the value of the currency can be predetermined, for example, "this many strawberries can be eaten per coupon."It is also possible to stipulate in the contract that cryptocurrency exchanges can only be conducted through person A. To cool, heat, or maintain the temperature inside a house or other structure, water is placed in a tank installed underground and then flowed down the roof or other parts of the structure. The ground temperature at a depth of about 5 meters underground is maintained at around 15°C year-round in Honshu, Japan, although this varies depending on the latitude. A tank is prepared there, and well water is first filled in. Using an electric pump or, if from a high point such as a mountain, water pressure is used to guide the water down the roof or other parts of the structure via pipes, allowing it to flow at an appropriate rate. The flowing water is collected using rain gutters or similar means and returned to the tank. The tank can be partitioned to prevent the returning water from mixing with the water in the tank until it has cooled down to a certain extent. The height of the partition inside the tank can be adjusted to control how much water accumulates before it overflows into an adjacent tank. Multiple tanks can be prepared, and the returning water can be stored in a separate tank for a certain period of time, and when that tank is full, it flows back into the original tank. If the tank capacity is large or the amount of water flowing is small, partitions may not be necessary. The amount of water flowing can also be adjusted by adjusting the output of the water pump. Similarly, flowing water on roads can provide cooling in the summer and melt snow or prevent freezing in the winter. The amount of water flowing can be programmed in advance using temperature data from weather forecasts, or the amount of water flowing can be controlled by adjusting the output of the water pump based on the actual temperature. If using spring water from mountains or well water (spring water sources and well water have stable water temperatures throughout the year), a tank may not be necessary. If you want to adjust the amount of water flowing, you can install valves on pipes that lead water to the roof, etc., and attach a device that can control the diameter of these valves, or control the amount of water flowing by using a computer to control the opening and closing of a faucet. Tanks do not necessarily have to be installed underground, but using water whose temperature is controlled by the ground temperature allows for temperature control inside houses with less water, reducing electricity costs for water pumps, etc. Making the tank long and narrow and extending to a depth of 5 meters or more underground, and circulating the water with a motor, can prevent freezing. It's also possible to install tanks underground and above ground, connect them, and mix the materials at the optimal temperature for the best results.Since the temperature varies depending on the depth underground, multiple tanks are installed at different underground depths and connected with pipes to mix the water, which is then flowed onto the roof of the house or other structures to improve efficiency. When flowing water onto the roof of a house or other structures, the water temperature and heat of vaporization are calculated to determine the most efficient flow rate. If water is guided through pipes to the highest point of the roof or other structures, gravity will cause the water to flow down the roof. Water can also be guided through pipes to flow not only on the roof but also on the sides of the house or other structures (for example, water can be guided through pipes above windows so that it flows down the sides of the windows). If the diameter of the roof is 5 meters, the pipes on the roof should also be about 5 meters long so that water flows across the entire roof. The pipes have holes at appropriate intervals (not necessarily 5 cm apart, but 5 cm intervals) from which the water comes out. In winter, the ground temperature at a depth of about 5 meters underground is about 15°C, and this water can be circulated through pipes under the flooring, sides, and ceiling of the house or other structures, collected in underground tanks, and reused. Using hot spring water, for example, would allow for the flow of even hotter liquids (water). To reduce the risk of patent holders being sued by others over their patents, the claims should detail the entire process necessary for the patent from start to finish when the patent is obtained. Once the patent is granted, if the patent holder uses the patent in a way that reproduces what is written in the patent, the risk of being sued by a third party for infringement or having to pay damages should be minimized. All manufacturing processes, materials, methods, and technical processes should be described in the patent. All phenomena in the procedures, materials, and processes when implementing the patent should be described in writing in the claims. After a patent is granted, anyone can anonymously file objections to that patent for six months, but patent attorneys can also file objections, as they are bound by confidentiality obligations stipulated in the rules. In that sense, they are stakeholders who know the contents earlier than the general public. Since those who can access the patent documents at the Japan Patent Office know the contents of the patent even before it is publicly disclosed, if such people conduct investigations well in advance, it could give them a one-sided advantage. Therefore, we will convey our opinion to the relevant organizations to stop anonymous objections and request that the rules be changed. By connecting materials such as plastic bottles, a space is created for people to pass through, allowing for internal temperature control as they move through. The connected plastic bottles are filled with a liquid (such as water) that maintains a stable temperature throughout the year, typically found at a depth of around 5 meters underground (this is just an estimate). This liquid is then pumped up and circulated through the structure to regulate the internal temperature when the outside temperature is high or low. While groundwater temperature fluctuates annually depending on depth, this fluctuation is also utilized to the fullest extent for climate control. Assuming a natural outside temperature of around 5 degrees Celsius, if the structure is sufficiently shielded, the internal air temperature will approximate that of 15°C water over time. Therefore, to reach approximately 22°C, only about 7°C worth of energy is needed to maintain the air temperature, which is more efficient than raising it from 5°C. The same applies when lowering the temperature. If hot water such as spring water is available, it becomes even more efficient when raising the temperature for climate control. Specialized materials can be used for the plastic bottle-like objects, provided they meet the intended purpose. Installation locations can be selected based on the application, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles are connected to allow water to flow. To do this, they are fixed with adhesive tape or similar material and the insides are hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When raising fish in a temperature-controlled space created using such a structure made from plastic bottles, if the fish swim fast, the structure should be as streamlined as possible to allow them to swim in large circles. Setting the width in the direction of travel to 50 centimeters, depending on the size of the fish, will prevent head-on collisions and ensure safety. In addition, by creating a difference in height in such a structure and moving the liquid from a lower position to a higher point with an electric pump, a water flow is created in a constant direction within the space containing the liquid that is in contact with the fish, preventing collisions. The water flow can also be stopped temporarily when necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing geothermal energy, to create a structure where plants of varying sizes are grown. Plants are then planted and cultivated within this structure, and moved to a care area using rails or wheels, maintaining limited and controlled air circulation from the outside world, thereby preventing pollination and complying with plant variety laws. A space isolated from the outside world is constructed using plastic bottles, and this is connected to the plant cultivation area with a hatch. After a person enters and confirms that the space is clean, the connecting hatch is opened, allowing humans to directly care for the plants inside, or to care for them mechanically using robotic arms and remote cameras. Plants transported to the care area via rails can be remotely monitored by cameras, and tasks such as thinning the plants can be automated through AI learning by installed machinery. When using materials such as PET bottles to construct a space, circulating liquids within it and utilizing the temperature of liquids in an underground tank for heating or cooling the space, it is possible to artificially heat (using equipment such as oil boilers) or cool (using equipment such as refrigerators or liquid nitrogen) the circulating liquids. However, it is also possible to use solar heat to heat the space, and the structure made of PET bottles can be used as a solar thermal storage water heater, saving on energy costs. By concentrating sunlight around the structure made of PET bottles, protecting the surroundings with airtight materials such as aluminum, and adding insulation, the heat retention efficiency can be improved. Structures made of materials such as PET bottles can have adequate space inside to grow plants, etc. If water or other liquids are circulated inside the PET bottles and transported via pipes connected to an underground tank, the temperature of the underground will be transferred to the inside of the space. The PET bottles act as a shield, blocking the space between the temperature-transmitting substance such as water and the surrounding space. If you are not pouring liquids that utilize underground temperatures into plastic bottles or similar containers, you can reduce the energy costs associated with artificially regulating the temperature inside the space using air conditioners or boilers by covering the container with a heat-insulating or heat-retaining material.When creating internal spaces within objects made of plastic bottles or similar materials, and the spaces are arranged in multiple levels, if sunlight cannot reach the lower spaces due to objects placed inside the upper spaces, a method can be used to concentrate sunlight at an appropriate position and transmit it to the necessary locations using optical fibers. Alternatively, reflective devices (such as mirrors) can be installed on the sides of the structure made of plastic bottles or other locations where light easily reaches, refracting the light and guiding it from areas with good light to areas with poor light. Since plastic objects like plastic bottles can be made transparent, it is possible to create an open space that allows light to pass through but is blocked, and it can be used as art if fish are kept inside. By changing the size of the space using a similar structure, it is possible to create a space that is integrated with nature by filling it with hot water or other leisure facilities. It is possible to create a relaxing hot spring that does not require worrying about rain or wind. The temperature inside the space and the temperature of the flowing water or other liquids can be controlled with sensors, and the flow rate of electric pumps can be automatically adjusted to maintain an optimal energy cost. When installed in mountainous areas, the structure can utilize nearby timber to heat surrounding water or the interior, effectively utilizing the heat generated by the combustion of wood and exhaust gases. Plants can be grown inside structures constructed using materials such as plastic bottles. Since the interior space of the structure does not need to be accessible to people, plants placed on pallets can be transported there using wheels, rails, or by connecting them like a train with motor power. The same applies when removing the plants. Pipes can be connected to a tank located about 5 meters underground (the depth can be adjusted depending on the temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using heating equipment), and water can be drawn from the tank using a motor pump and poured onto the exterior of the structure. If the structure's exterior is constructed with steps or other features, liquid water or coolant can be flowed to the highest point of the structure, preventing it from falling all at once and maintaining a balance of temperatures around it. In this way, the structure can be cooled or heated. Piping for water intake can be installed at appropriate points in the structure, allowing water to be returned to the underground tank.When constructing a structure using plastic bottles, holes can be made in the sides of the bottles when connecting them, allowing the water inside the connected bottles to be moved as desired. While structures constructed from plastic bottles can have water circulated between tanks using a motor pump, it's also possible to leave them filled with a suitable antifreeze (clear is generally better for this purpose, but colored is acceptable in some cases), water, glass, marbles, plastic resin, or other light-transmitting materials (colored materials may be better in some cases to adjust the amount of sunlight; a light-blocking cover can also be placed on the outside). This allows for temperature control within the structure by circulating water from underground tanks or hot springs to the outside, then collecting and recirculating it. This can improve the cost-effectiveness and strength of the structure. Structures using plastic bottles are not limited to plastic bottles; specialized materials can also be used. One application of structures constructed from plastic bottles is to separate the internal space from the outside air.

This allows for temperature control within the structure by circulating water from underground tanks or hot springs to the outside, then collecting and recirculating it. This can improve the cost-effectiveness and strength of the structure. Structures using plastic bottles are not limited to plastic bottles; specialized materials can also be used. One application of structures constructed from plastic bottles is to separate the internal space from the outside air. When creating multi-purpose spaces inside structures made from plastic bottles, etc., when liquids poured from above move due to gravity, gaps can be created between the plastic bottle structures, or a certain rim-like step can be added to the edges of the plastic bottle structures to control the movement of the liquid and improve the efficiency of transferring the liquid's temperature to the space created inside. If natural spring water, hot spring water, or river water is placed in multiple or single tanks installed underground at high altitudes and then transported by gravity to plastic bottle structures at slightly lower altitudes using pipes, the electricity costs for pumps etc. can be almost eliminated, making it eco-friendly (theoretically possible to use only natural energy). When putting liquids in spaces made from plastic bottles and allowing fish to swim, the swimming area of ​​the structure can be made streamlined to reduce the risk of fish colliding with obstacles. The entire structure can also be made into a large loop shape, and water pressure can be created using pumps and fans to generate water flow inside the space. Creating a space with a large circle structure that curves gently can prevent fish from coming into contact with walls etc.If the space for fish to swim is about 50 centimeters wide (this is just a guideline, and depends on the size of the fish), it will help prevent the fish from colliding with the sides. For heat control using groundwater, etc., and for the space where temperature is regulated using that, by arranging structures made of plastic bottles etc., you can put a liquid for temperature regulation inside and create a space around it where plants or people can enter, and you can freely choose the arrangement. By attaching a structure made of plastic bottles etc. with spaces of the appropriate size inside to a tank set to a certain temperature, the temperature of the liquid in the tank may affect the space inside the structure made of plastic bottles etc., and the temperature of that space can be regulated. The space can be sealed, or air can be introduced or removed through filters etc. The present invention aims to solve the above problems and to provide a constant temperature water (liquid, heat-transmitting substance) utilization device that can utilize the benefits of nature regardless of weather. To achieve the above problems, the constant temperature water (liquid, heat-transmitting substance, coolant, etc.) utilization device of the present invention is a constant temperature water utilization device that utilizes water at a constant temperature, and comprises: an underground tank buried in a predetermined underground location where a predetermined constant underground temperature is maintained and which stores water at a constant temperature; a structure formed by connecting a plurality of hollow tubes made of a light-transmitting material to form a cavity inside; pipes and a circulation pump for circulating the water at a constant temperature stored in the underground tank through the hollow tubes of the structure; and a fan for blowing air from one end to the other in the cavity formed by the structure, wherein the cavity is used as an air conditioning space or an energy exchange equipment installation space. With such a configuration, water at a constant temperature can be effectively utilized. Furthermore, another aspect of the present invention relates to a constant-temperature water utilization device, which is a constant-temperature water utilization device that utilizes water at a constant temperature, and is characterized by comprising: an underground tank buried in a predetermined underground location where a predetermined constant underground temperature is maintained, for storing water at a constant temperature; a conduit for guiding the water at a constant temperature stored in the underground tank to the vicinity of a conduit; and a plurality of pipes connected to the conduit and buried to a predetermined depth from the road surface in order to maintain the temperature on the conduit surface at a predetermined temperature with the water at a constant temperature. Geothermal energy is used to create a liquid (using water, etc.) from a tank installed underground (which may be installed at multiple points at different depths) and guide it to a target location to control the temperature of a target object or place. With such a configuration, water at a constant temperature can be effectively utilized.Furthermore, another aspect of the present invention is a constant-temperature water utilization device that utilizes water at a constant temperature, comprising: an underground tank buried in a predetermined underground location where a predetermined constant underground temperature is maintained and which stores water at a constant temperature; a wall formed by connecting a plurality of hollow tubes in a planar manner; a structure formed by creating a cavity inside using the wall; and pipes and a circulation pump for circulating the water at a constant temperature stored in the underground tank through the hollow tubes of the structure, wherein the cavity is used as an air-conditioned space. With such a configuration, water at a constant temperature can be effectively utilized. Furthermore, a trolley according to one aspect of the present invention is a trolley that transports an automobile by traveling on rails on which an ice surface of frozen liquid has been formed, and is characterized by comprising: a trolley body that supports the weight of the automobile to be transported; a plurality of sleds provided on the lower surface of the trolley body that slide on the ice surface; a drive device that moves the trolley body; a position information acquisition means that acquires position information of the trolley body along the rails; and a control device that controls the drive device based on the position information obtained by the position information acquisition means and drives the trolley body to the destination. With such a configuration, an automobile can be transported energy efficiently by inertial motion through sliding on ice with little resistance, and the driver of the automobile being transported can rest from driving during transport. (Constant temperature water utilization device) Hereinafter, a constant temperature water utilization device according to one embodiment of the present invention will be described with reference to the drawings. Next, a constant temperature water utilization device 6 according to one embodiment of the present invention will be described with reference to Figure 1. The constant temperature water utilization device 6 is a device that utilizes water at a constant temperature. The constant-temperature water utilization device 6 comprises an underground tank T, a structure 60, pipes 62 and a circulation pump P3, and a fan 63. The underground tank T is buried in a predetermined underground space where a predetermined constant underground temperature is maintained, and stores water at a constant temperature. For example, in Japan, a depth of 5 meters underground maintains a constant underground temperature environment of about 15°C throughout the year, so the constant temperature characteristics of such an underground space can be utilized as a natural resource. The temperature of the underground space can be a constant temperature space within various temperature ranges depending on the surrounding environment in which the underground space is located, such as a hot water-containing layer like a hot spring or a groundwater layer of melted snow.By selecting such an underground space and installing the underground tank T, it is possible to store and utilize constant-temperature water at a predetermined temperature. In this invention, the term "water" in the context of the constant-temperature "water" stored and utilized in the underground tank T is a broad term encompassing water and other liquids that can be substituted for water. The constant-temperature "water" stored and utilized in the underground tank T may be, for example, a refrigerant in an air conditioning system, a heat exchange fluid, or oil. The underground tank T is placed in an underground space with a predetermined constant temperature, for example, near a groundwater layer containing groundwater at a predetermined constant temperature. Once the underground tank T is installed in the predetermined location, water is injected into it to a predetermined full volume. The water stored in the underground tank T may be groundwater at the tank's installation location, or it may be, for example, tap water injected from the surface. By injecting water close to the original temperature of the underground space in which the underground tank T is installed into the underground tank T, constant-temperature water can be made available quickly. Water stored in the underground tank T is pumped up to the surface by a water pump P2. After being used as constant-temperature water, the water stored in the underground tank T is transferred to the underground space, returned to constant-temperature water underground, and then returned to the underground tank T for reuse as constant-temperature water. The structure 60 has a cavity 61 inside, formed by connecting multiple hollow tubes 6a made of a light-transmitting material. The cavity 61 is used as an air conditioning space or an energy exchange equipment installation space. The structure 60 may be installed above ground when used in the presence of sunlight, for example, and underground in other cases. When installed underground, it is easier to use it at a predetermined constant temperature. The structure 60 is used as a sealed space by sealing both ends with walls formed by connecting the hollow tubes 6a. The structure 60 may also be used as an open space with parts of both ends open. Pipe 62 and circulation pump P3 are used to circulate constant-temperature water, stored in the underground tank T and pumped up by the water supply pump P2, through the hollow tube 6a of the structure 60. The circulation of water within this hollow tube 6a keeps the internal temperature of the cavity 61 constant. The constant-temperature water is stored in the auxiliary tank T1 as needed, circulated through the hollow tube 6a, and then returned to the underground tank T.The constant-temperature water utilization device 6 is equipped with a recovery device that returns water taken from the underground tank T and used back to the underground tank T. The recovery device consists of a pipe 69 connecting the structure 60 and the underground tank T, and recovery tanks Ts attached to the underground tank T, and a recovery pump for supplying water may be provided in the path of the pipe 69. The water that is used and recovered is at a different temperature from the temperature of the underground space in which the underground tank T is installed. Therefore, recovery tanks Ts are used to return the temperature of the recovered water to the temperature of the underground space, i.e., the constant temperature. In this embodiment, the recovery tanks Ts are attached to the underground tank T, but they may be separated from each other and connected by pipes. Also, the recovery tanks Ts may be equipped with a heat exchanger configured to allow the recovered water inside to quickly return to the temperature of the underground space. Furthermore, if the amount and temperature (i.e., heat) of the recovered water are small and negligible compared to the heat of the constant-temperature water in the underground tank T, then temperature fluctuations can be ignored, and the recovered water may be directly recovered and mixed with the constant-temperature water in the underground tank T. The configuration of the pipe 62 for circulating and utilizing the water in the underground tank T, the circulation pump P3, and the auxiliary tank T1 is an example and is not limited to the illustrated configuration. Pipes, pumps, auxiliary tanks, valves, and other control equipment may be provided as needed. The auxiliary tank T1 is also optional and may be provided as needed. The fan 63 creates airflow in the sealed cavity 61 formed by the structure 60. This airflow prevents stagnant air in the cavity 61. The heat generated in the cavity 61 is carried to the wall surface of the hollow tube 6a by the airflow from the fan 63 and absorbed. The structure 60 may be equipped with external piping from one end to the other to form a closed air passage, and the airflow from the fan 63 may create a unidirectional circulating airflow within the structure 60. The cavity 61 is suitably used as an installation space for a solar panel 64, as shown in Figure 2. A solar panel 64 is an energy exchange device that converts solar energy into electrical energy. The solar panel 64 is located in a cavity 61 where all four sides are maintained at the temperature of the groundwater, and is ventilated by a fan 63, so the panel surface can be kept at an appropriate temperature and power generation efficiency can be maintained.This mechanism allows for the maintenance of a suitable temperature not only for solar panels but for any object. The structure 60 can be shaped appropriately to optimize and streamline temperature control of the contents contained within the cavity 61, depending on the contents housed there. For example, in the case of the solar panel 64 shown in Figure 2, the cavity 61 may be sealed by surrounding it with a wall formed of a hollow tube 6a, close to the outer circumferential surface including the front and back surfaces of the panel, so that the panel can be housed in the smallest possible space. Alternatively, it may be an unsealed cavity 61 with a portion open. Next, an example of the application of the constant temperature water utilization device 6 will be described with reference to Figure 3. This constant temperature water utilization device 6 has multiple (three in the illustrated example) underground tanks T and a mixer 6mx that mixes water of known temperature from each tank. The underground tanks T are individually buried in underground spaces of multiple depths or different underground environments so that they can store constant temperature water at different temperatures t1, t2, and t3. The mixer 6mx mixes constant-temperature water at different temperatures t1, t2, and t3 obtained from these multiple underground tanks T, thereby supplying constant-temperature water adjusted to a predetermined temperature t0 regardless of the season. This embodiment assumes that the temperature of the water in each underground tank is constant in the short term, but fluctuates seasonally over the long term throughout the year. According to this embodiment, even if there are seasonal fluctuations in the temperature of each stored water, the predetermined temperature can be maintained by changing the mixing ratio considering the temperature difference of the water stored in each underground tank T. (Other embodiments of constant-temperature water utilization device) The device of this embodiment is a constant-temperature water utilization device that utilizes constant-temperature water, similar to the embodiment described above, and uses underground tanks T that are buried underground in a predetermined underground area where a predetermined constant underground temperature is maintained and which store constant-temperature water. The constant-temperature water utilization device of this embodiment includes, in addition to the underground tank T, a conduit that guides the constant-temperature water stored in the underground tank T to the vicinity of the conduit, and a plurality of pipes connected to the conduit, which are buried to a predetermined depth from the road surface in order to maintain the temperature on the conduit surface at a predetermined temperature with the constant-temperature water.According to this embodiment, even on existing roads, in order to prevent freezing and lower the temperature of the road surface in summer, an underground tank T is installed 5 meters underground beneath or near roads and walkways, and the constant-temperature water stored in the underground tank T is transported using pipes, etc., and the constant-temperature water is circulated 10 centimeters below the asphalt of the road, thereby preventing the road surface from freezing or becoming excessively hot. (Further Embodiments) The apparatus of yet another embodiment is a constant-temperature water utilization apparatus that utilizes constant-temperature water, similar to the embodiments described above, and uses an underground tank T that is buried in a predetermined underground area where a predetermined constant underground temperature is maintained and stores constant-temperature water. The constant-temperature water utilization apparatus of this embodiment includes, in addition to the underground tank T, a wall formed by connecting a plurality of hollow tubes in a planar manner, a structure that forms a cavity inside using the wall, and pipes and a circulation pump that circulate the constant-temperature water stored in the underground tank through the hollow tubes of the structure, with the cavity serving as an air-conditioned space. This device includes pipes, a recovery pump, a recovery tank, and a valve for pumping water from underground tank T and recovering it after use. Lubricants and other control devices may be provided. The hollow tube may be transparent or not, and a part of the wall of the cavity may be made transparent to serve as a window for light, so that the optimal air-conditioned space can be configured according to the application. According to this embodiment, a space the size of a futon (the size of the space may be changed, and it may be larger or smaller) can be created as an air-conditioned space, and the temperature inside the space can be kept cool in the summer and warm enough not to freeze in the winter. Furthermore, if water is pumped using a motor or the like, or installed underground in a high mountain, or if a large underground tank linked to a large-scale facility such as a water treatment plant is used to send water that is cold even in the summer, close to 15℃, to each household, then the water in the underground tank T can be used at a constant temperature using only water pressure. (Cart that moves on a sled) Next, a cart according to one embodiment of the present invention will be described with reference to the drawings. As shown in Figures 4 and 5, the cart 8 is a cart that travels on a pair of left and right rails 23 on which an ice surface 2a of frozen liquid is formed to transport an automobile 90. The trolley 8 comprises a trolley body 80 that supports the weight of the automobile 90 to be transported, a plurality of sleds 81 provided on the underside of the trolley body 80 for sliding on the ice surface, and a drive device (traveling wheels 85) for moving the trolley body 80. In this embodiment, the trolley 8 further comprises transport sleds 84 on which the rear wheels 9b of the automobile 90 are placed and which slide on the ice surface 2a. The trolley body 80 is used to share the weight of the automobile 90 with the rails 23, so the front wheels 9a on the side not placed on the transport sleds 84 are placed on it. Whether to place the front wheels 9a or the rear wheels 9b on the trolley body 80 can be arbitrarily selected according to the characteristics of the automobile 90. The trolley 8 further comprises a position information acquisition means 82 for acquiring position information of the trolley body 80 along the rails 23, and a control device 83 that controls the drive device based on the position information obtained by the position information acquisition means 82 and drives the trolley body 80 to the destination transport location. The bogie 8 is equipped with a braking device for controlling its movement. The pair of left and right rails 23 are rails that guide the ice-sliding sled 81, and an ice surface 2a is formed by freezing liquid. The rails 23 consist of a housing fixed to the road surface 20 with a concave cross-section having grooves formed in the longitudinal direction, and a refrigerant pipe that carries a refrigerant placed inside the grooves. Water is placed in the grooves of the housing and cooled by the refrigerant pipe to form ice.The surface of the ice becomes the ice surface 2a when the sled 81 slides on the ice. The rail 23 may be equipped with a cover to prevent rain from entering the interior when the sled 81 is not sliding on the ice, and may also be provided with drain holes to discharge water present on the ice surface 2a. It is desirable to improve cooling efficiency by configuring the cover and the housing of the rail 23 to circulate water from an underground tank through pipes, for example. Guide wheels close to the outer surface of the rail 23 may be provided on the lower part of the bogie body 80. The guide wheels guide the bogie body 80 so that the bogie 8 runs along the rail 23. Such a guiding device may be provided between the sled 81 and the rail 23. For example, the structure on the rail 23 may be configured to enclose and surround the sled 81 so that the sled 81 does not deviate from the rail 23. The drive device is a running wheel 85 powered by an engine or motor mounted on the bogie body 80. The running wheels 85 are configured to move up and down relative to the bogie body 80, and when not driven, they are moved upward so as to move away from the road surface 20. When moved upward, the bogie body 80 skids on the ice surface 2a by the skid 81. In addition, when driven, the running wheels 85 contact the road surface 20 to make the bogie body 80 run on wheels. The running wheels 85 are also used as a braking device. The bogie 8 may also be an embodiment in which the bogie body 80 is moved using a drive device that does not have running wheels 85. For example, a jet propulsion device or a propeller propulsion device may be mounted on the bogie body 80 as the drive device. Alternatively, a linear motor may be used as the drive device. In this case, the track that forms the magnetic field of the linear motor may be covered with a liquid that freezes to form an ice surface. Alternatively, a linear motor and running wheels 85 that obtain driving force from an engine or motor mounted on the bogie body 80 may be combined as a drive device. The position information acquisition means 82 may be configured, for example, using a sensor that successively detects position indicators or markers installed along the rail 23 to acquire position information, or it may be configured to acquire position information using GPS functionality, or a combination of these. The braking device may be configured as a braking device for a normal tire-driven vehicle that brakes the running wheels 85 that constitute the drive device by placing them on the road surface 20.The braking device is a braking device that does not use running wheels 85 and may be a device that brakes by interaction with the rails 23. For example, it may be a device configured to clamp a brake plate provided on the side wall of the rails 23 with a brake shoe provided on the lower part of the bogie body 80. Alternatively, braking may be applied non-contact by electromagnetic interaction between a coil arranged along the rails 23 and a coil placed on the lower part of the bogie body 80. Furthermore, as a device that brakes without direct interaction with the rails 23, a wind-receiving plate may be placed on the bogie body 80, and braking may be performed by the wind pressure when the wind-receiving plate is extended. The control device 83 controls the running of the bogie body 80 using the braking device described above and runs the bogie body 80 to the target transport destination based on the position information obtained by the position information acquisition means 82. Based on the position information obtained by the position information acquisition means 82, the control device 83 also selects an appropriate route and controls the running, even when the rails 23 branch. With the trolley 8 of this embodiment, the driver of the automobile can entrust the transport of the automobile to the trolley 8 and take a break or do something other than drive during transport. The trolley 8 of the present invention is not limited to a configuration that includes the transport sled 84 described above, and may be configured to place the entire automobile 90 on the trolley body 80. Furthermore, the drive device is not limited to one that uses running wheels 85, and may be configured to use a rocket propulsion device, propeller propulsion device, or jet propulsion device. (Trolleys of other embodiments) Next, with reference to Figure 6, a trolley 8 of another embodiment will be described. The trolley 8 of this embodiment is configured to place the entire automobile 90 on the trolley body 80 and to run by the driving force of the automobile 90, and is otherwise the same as the trolley 8 of the above embodiment. The drive device of the trolley 8 of this embodiment includes a rotation transmission device 86 that receives the rotational force of the drive wheels (front wheels 9a in this example) of the automobile 90 placed on the trolley body 80 and transmits it to the running wheels 85. The rotational transmission device 86 includes a rotatable roller that supports the front wheel 9a, which is driven and rotated by the engine of the automobile, from below, and a transmission mechanism that transmits the rotational energy of the roller to the traveling wheel 85. According to this embodiment of the trolley 8, it can move using the power of the transporting automobile 90 without the need for a motor or engine to drive the traveling wheel 85.The driver of the car can move along with the car 90 by letting the trolley 8 move on its own. (Note) (Movement: sled, trolley) By using the natural principle that the temperature around 5 meters underground in mainland Japan is maintained at about 15 degrees Celsius throughout the year, and by grounding a tubular tunnel there, energy required for cooling can be saved. Alternatively, this structure can be installed above ground, and when cooling, the outer circumference of the tube can be covered with liquid water, etc. If the outer circumference of the tube is made of a light-transmitting material such as plastic or glass, the scenery can be seen from inside the car. A ship or the like can be run with the inside sealed by filling a similar tunnel with water, etc., and by creating a vacuum inside the tunnel, the energy efficiency during movement can be increased (anything that can travel inside a tunnel can be applied). Energy costs can be reduced by adopting a similar structure for cars, not just large vehicles like trains. It can also improve the reliability of autonomous driving of cars. Cars can be connected to trolleys etc. installed on a similar platform, and the weight of the cars can be mainly supported by sleds to reduce rolling resistance, etc. This trolley may incorporate motors or other devices to transmit power by contacting the road surface, or it may connect the power from the engine or motor of an automobile to the trolley's power unit while the automobile is mounted on the trolley, or the trolley may be equipped with a device to transmit the rotational force of the automobile's wheels to the road surface as needed. There are various methods. Alternatively, even without using existing automobiles, if it is a four-wheeled vehicle, two extra wheels may be attached to the center of the vehicle body, so that this part does not come into contact with the ground during normal driving. However, by using hydraulics to change the angle or by changing the angle, the structure can be made so that the four wheels are used to drive onto the trolley, and the remaining two wheels (rubber, iron, etc.) can be used hydraulically to make contact with the upper part of the cooling rail as needed. Alternatively, the trolley may be equipped with a hydraulic jack function so that after the automobile is mounted on the trolley, the vehicle on the trolley can be raised or lowered using hydraulics, thereby changing the height of the automobile's tires and preventing them from coming into contact with the ground. Motors or other devices to provide driving force during operation can be installed on this bogie, or a portion of the bogie can be powered to pull or push it, or it can be coupled with other bogies like a train, or powered bogies can be appropriately placed to reduce installation costs.It is also possible to monitor the movement of the trolley (unit) with sensors or install cameras around the cooling lane so that the trolley can be controlled automatically and unmanned. Solar panels can be installed near the space where the cooling lane is installed, and the power from them can be used to guide the motor of the trolley from the metal part of the lane, or contactless power transmission can be used so that the electrical receiving part of the lane and the trolley do not have to come into direct contact. There are several ways to convert the energy of the car's engine and motor into driving energy by connecting it to tires (even iron wheels) that can be attached to the side of the tires of a car, etc., so that their rotation does not come into contact with the road surface or the upper part of the cooling rail where there is no ice, etc., on the trolley, etc. Another method is to attach a device to the trolley that rotates rollers underneath when the engine etc is rotated in place without changing the position of the car passing through inspection, and connect it to wheels with a mechanism that converts the rotational energy of the rollers so that they do not come into contact with the road surface on the trolley wheels. To prevent the road surface, which transmits the driving energy, from freezing, water heated to about 15 degrees Celsius by geothermal energy stored 5 meters underground is guided through pipes to the vicinity of the road surface. The water is then collected in a tank by a motor pump and circulated. For emergency stops, stakes or similar objects are installed at the rear of the bogie, and these can be lowered to the road surface as needed to bring the train to a quick stop. Even when obtaining energy in the direction of travel using technologies such as linear motor cars, if a portion of the magnetic field of the linear motor car track is cooled and covered with ice, and skids or other objects that reduce resistance during movement are attached, the force that would otherwise be used for vertical levitation by electricity can be saved, and most of the electrical energy can be concentrated into energy in the direction of travel, making it more efficient. The direction of the magnetic energy acting on the levitation energy and the energy that accelerates in the direction of travel of the linear motor car is adjusted to conserve electrical energy as much as possible, such as keeping the levitation energy low, in order to balance power consumption and speed during movement to the most efficient extent. In practice, even if it is not levitating, the skids or other objects reduce resistance and allow it to move. From the perspective of ride comfort, etc., it is also possible to lightly sprinkle water on frozen surfaces.A maglev train may be fitted with a skid and the aforementioned powered wheels. The tunnel can be made to a near-vacuum state to eliminate wind-induced losses and reduce noise. The magnetic energy transmission section and the skid mechanism in the maglev train may be installed separately. Wings may be attached to the top of the vehicle for lifting. By gaining power and controlling air resistance, friction with the cooling lane can be reduced or adjusted to lessen the frictional force on the vehicle's skids against the cooling lane, or conversely, push the vehicle down towards the cooling lane. To prevent skids from derailing from the cooling lane, the cooling lane can be made into a zipper-like shape to secure the skids in place. The direction of the wings can be changed, and the balance of lift can be adjusted on the left and right sides to make it easier to turn corners. When decelerating, the flaps can be adjusted to increase air resistance. In case of emergency stops, a parachute can be deployed from the vehicle. To prevent the parachute from getting entangled, the device with the parachute attached can be detached from the rear of the vehicle and moved along the lane, allowing for a safe stop while utilizing the parachute's effect. The parachute device is connected by wires through a device that moves along the cooling lane, and the device and the vehicle are also connected by wires. Various energy sources can be considered for the movement of such vehicles, such as wheel drives, jet engines, or propellers attached to the sides or rear of the vehicle. After accelerating considerably, the vehicle can take off with its direction of travel facing the sky, and from there it can glide, or use jet engines or rockets attached to the vehicle as propulsion, or the lift generated by wings to move at high speed, or launch satellites and place them into orbit while saving fuel. One method is to accelerate sufficiently on a cooling rail and launch it upwards, separating only the satellite (for example, by separating it with compressed gas pressure), and then using jet engines to further accelerate it. Alternatively, jet engines or rockets can be used from the beginning to accelerate on the cooling rail. To cool the parts that the skids are in contact with, long, narrow heat-absorbing plates from freezers can be installed, or a dedicated heat absorption device can be used, or efficient temperature control can be achieved using a large compressor and water at a constant temperature underground. The waste heat from the compressor can be reused to power a Stirling engine or similar. Water drawn from 5 meters underground can be circulated around the compressor using pipes, etc., and heat exchange can be performed where needed to help with heat dissipation.To cool the water in the cooling lane, a pipe is installed nearby and a dry gas is placed in it. Then, the cold air, such as dry ice, can be circulated using a fan, or a tank filled with low-pressure carbon dioxide can be used at the pipe's outlet to draw it in. Once the carbon dioxide is collected at the end, the cooling gas can be circulated in the reverse direction using another pipe, thus saving storage space for the carbon dioxide. Fans can also be installed in the middle of the pipe as needed. The carbon dioxide collected through the pipe can be reused as dry ice. It is also possible to obtain carbon dioxide gas by heating dry ice in a vacuum and introduce it into the pipe. When sending it through the pipe, compression can be used to increase the speed. In current roads, to prevent freezing and lower the road surface temperature in summer, water is circulated through pipes in tanks installed 5 meters underground beneath the road or walkway to a depth of approximately 10 centimeters below the asphalt, preventing the road surface from freezing or overheating. By circulating water through pipes around the sled section, cooling efficiency can be improved, especially in summer. Using plastic bottles, a futon-sized space (it can be larger or smaller, the size can be changed) can be created to maintain a temperature that is cool in summer and warm enough to prevent freezing in winter. Water from a tank installed about 5 meters underground can be placed inside plastic bottles using pipes, and these bottles can be connected to circulate the water back into the tank. Water can be pumped using motors, installed underground in high mountains, or connected to large-scale facilities such as water treatment plants. If the water is kept cool, close to 15°C even in summer, and delivered to each household, pumping can be done using only water pressure. By attaching a sealed cover or similar structure to the top of the cooling rails (lanes), and circulating water at around 15°C from the underground tanks through it, the cost of the cooling tower can be reduced. Cooling rails and lanes are designed to minimize heat exchange, and in the summer, the upper covers are closed electrically, but when vehicles pass, sensors should be used to detect their presence and allow the covers to open and close automatically with motors. (Note) (Movement: Sled) To make emergency stops for trains, pipes should be installed under the train tracks and oil (or a gas, considering viscosity, etc.) should be poured into them.Then, a hole is made in the top of the pipe, and stakes or similar objects are dropped from the train or other vehicle and hooked into it. Where the stakes or other objects fall, they come into contact with a round plate or similar object made close to the edge of the pipe to prevent pressure from escaping, similar to an air gun, increasing the pressure inside the pipe and slowing down the train. If multiple pipes are installed and there are multiple stakes or similar objects on the train, the braking force on the train can be adjusted by first hooking one stake (a rod-shaped object used to hook the vehicle or other vehicle to the outside), and then adding a second, third, and so on. Holes are made in various places in the pipe to release pressure, and when a certain pressure is reached, the plugs or similar objects will come off, preventing the pipe from breaking due to excessive pressure. To reduce the air resistance of the train, the train doors are made to be hinged so that passengers can board and alight from there, lowering the height of the train. A valve or dedicated hole in an adjacent section can be installed to allow liquids or gases to pass through. This valve can be used in brakes, etc., and is designed to release when the pressure in the pipes containing liquids or gases exceeds a certain level. This valve can be removed when the pressure in the pipes exceeds a certain level (or the valve can be mechanically removed, such as by a device that can remotely open and close doors or other openings designed to allow liquids or gases to pass through the inside of the pipes). Alternatively, a hole can be made in another pipe to allow liquids or gases to pass through, and this can be connected to a section with a plate that transmits pressure to the adjacent section. By installing a pressure-reducing valve or a dedicated hole in the adjacent section and connecting them, when pressure is applied, the liquid or gases will move to that section, thereby increasing braking power. Under normal circumstances, the pipes contain an appropriate proportion of liquid, gas, etc., to prevent sudden shocks to the vehicle. Furthermore, a dedicated device (such as a hydraulic pump) can be prepared to supply liquid, gas, etc., to the pipes as needed, allowing for the rapid supply of oil, liquid, solid, etc., to the required sections at the required time. When connecting a vehicle to a stake or similar structure (such as a mounting post), shock absorbers such as springs or hydraulic shock absorbers can be installed between the vehicle and the stake to mitigate impacts to the vehicle. When freezing liquids such as water in the cooling lanes, gases such as carbon dioxide can be filled into the pipes, and compressed or blown dry ice-like vapor can be pressurized and supplied through them.The material is then collected at the end of the pipe and reused by returning it to a dry ice state or a very low temperature state before it solidifies, and then returning it to its original direction using another pipe. (Note) (Movement: Sled) When using cooling rails, etc., to slide vehicles using sleds, etc., the lanes can be coated with a rough material, the wheels can be covered with rubber, etc., or rubber tires can be used to ensure that the wheels that transmit power have a secure grip. Superconducting magnets, magnets, etc. can also be installed on the sides or underside of the vehicle, and coils can be installed on the sides or center of the lanes to generate electricity. Coils can also be installed on the vehicle side and magnets on the lanes side. Batteries can be mounted on the vehicle to power the drive motors or to charge the electricity generated. Electromagnetic force can also be used to balance the sides, similar to a linear motor car, and the cooling rails can be used in conjunction with a linear motor car, with the electricity generated by the vehicle using the cooling rails driving the linear motor car as well. (Note) (Underground Tank) To cool solar panels, etc., water kept at a constant temperature in an underground tank with a circulation system as described above is flowed over the panels, or a pipe-like structure made of a light-transmitting material is installed nearby, and water at about 15°C from an underground tank (located 5m underground and kept at a nearly constant temperature year-round, such as in Honshu, Japan. The temperature varies depending on the well, so the same effect can be obtained by changing the depth) is flowed through it to control the temperature of the solar panels. Alternatively, the solar panels can be made waterproof and airtight, and placed in a bucket or similar container filled with shallow water, and water at about 15°C, such as that installed at about 5m underground, is flowed through it and then collected back into the underground tank. At this time, in order to maintain the target object (there are no particular restrictions, other materials or objects can also be used) at an appropriate temperature, the temperature can be controlled by arranging pipes or similar structures to surround the target object. In this case, it is not always necessary to use a fan to blow air. To control the temperature of an object or substance that needs to be kept at a suitable temperature, the constant temperature of an underground tank (around 15°C) can be utilized by using water or other liquids (coolant, etc.) as a medium, and then moving it through pipes or similar means.To maintain an object (such as a solar panel) at an optimal temperature, a system can be constructed where a liquid, water, or coolant, pre-configured to fit the dimensions of the object, moves through pipes while retaining heat, and is collected in a tank located 5 meters underground. There, the temperature is adjusted by the ground temperature, becoming lower than the ambient temperature in summer and warmer in winter, thus enabling temperature control. If the location allows for natural groundwater flow, a continuous flow system can be used to control the panel temperature. A structure can be constructed by cutting off the opening of a plastic bottle, for example, and gluing together multiple rectangular cubes to create a structure into which water from the underground tank can be placed. Using materials that allow light to pass through but not water, such as plastic bottles, a hollow structure can be created that holds water. The solar panel or other object whose temperature needs to be controlled can then be placed in this hollow section. This same device can be used to increase the power generation of solar panels installed in homes, as solar panels reduce power generation when they become too hot. Furthermore, to efficiently air-condition the space, water at approximately 15 degrees Celsius from the underground tanks mentioned above is used. Since the ground temperature around the underground tanks varies with depth, multiple tanks can be installed at different depths, and the water from these tanks can be mixed. (Note) Even on existing roads, to prevent freezing and lower the road surface temperature in summer, water from tanks installed 5 meters underground beneath roads and walkways is circulated through pipes to about 10 centimeters below the asphalt of the road, preventing the road surface from freezing or overheating. Circulating water can also be routed around the sled section through pipes to improve cooling efficiency, especially in summer. Using plastic bottles, a futon-sized space (it can be larger or smaller; the size can be changed) can be created to maintain a temperature that is cool in summer and warm enough to prevent freezing in winter. Water from tanks installed about 5 meters underground is routed through pipes into plastic bottles, and the bottles are connected so that the water circulates and returns to the tanks.By using motors to pump water, installing large underground tanks in high mountains, or linking them to large-scale facilities such as water treatment plants, and sending cool water (around 15°C even in summer) to each household, water can be pumped using only water pressure. To reduce the cost of cooling towers, a sealed cover or similar structure can be attached to the top of cooling rails (lanes), and the 15°C water from the underground tanks can be circulated through it. To minimize heat exchange, the top covers of the cooling rails and lanes are closed electrically, especially in summer, but sensors can be used to detect vehicle traffic and automatically open and close them with motors. The wheels of trains and other vehicles are replaced with sleds or similar vehicles. Instead of rails, a width just wide enough for the sleds to pass is created, and water or other liquids are placed in this area and cooled using electricity or other means to freeze it, thereby reducing friction and minimizing energy loss. Wheels or similar vehicles are used to contact the gaps between rails for acceleration and deceleration. When speed is achieved, these wheels or similar vehicles can be retracted into the vehicle body using electricity or other means to reduce resistance and prevent contact with the ground. The sled portion slides on frozen surfaces, but the rail structure has protruding shapes to prevent sideways derailment. Tires or similar vehicles can be attached to the sides of the rails to reduce impact on curves. The route is designed to descend slightly, using gravitational energy for acceleration. The route can also be designed without elevation changes, but even if it is an uphill route, the friction is reduced by the sleds, so the energy of inertia can be used as an energy source to move the object to higher ground. Even on a slight downhill slope, the resistance at the contact points of the vehicle body is extremely low, allowing the vehicle to accelerate rapidly with only a small amount of energy supplied by the tires. The same applies to linear motor cars and other vehicles that do not make contact with the ground. Furthermore, air resistance can be prevented by creating as much of a vacuum as possible inside the tunnel, such as a tube surrounding the vehicle. Possible methods include opening hatches on the vehicle to create a passage to the outside when it arrives at a station, or installing partitions or doors that open and close from above and below within the tunnel, allowing air to be partially introduced at stations to allow passengers to enter and exit. Holes can also be made on the sides to allow rain to escape if it enters the cooled road surface, or rain covers can be installed. By utilizing the natural principle that the temperature at a depth of around 5 meters underground in mainland Japan is maintained at about 15 degrees Celsius throughout the year, the energy required for cooling can be saved by grounding a tubular tunnel there. Alternatively, when this structure is grounded and cooled, it is possible to cover the outer circumference of the tube with liquid water or the like. If the outer circumference of the tube is made of a light-transmitting material such as plastic or glass, it is possible to see the scenery from inside the vehicle.Similarly, a ship could be run in a tunnel filled with water or similar material to create a vacuum inside the tunnel, increasing energy efficiency during travel (this can be applied to anything that can travel through a tunnel). Even vehicles like cars, not just large trains, can use a similar structure to reduce energy costs. This would also improve the reliability of autonomous driving in vehicles. A vehicle could be connected to a trolley or similar platform, with the weight of the vehicle primarily supported by the sled, reducing rolling resistance. Motors could be incorporated into this trolley to transmit power by contacting the road surface, or the power from the vehicle's engine or motor could be connected to the trolley's power unit while the vehicle is mounted on it. There are various methods, such as equipping the trolley with devices to transmit the rotational force of the vehicle's wheels to the road surface as needed. Furthermore, even without using existing vehicles, a four-wheeled vehicle can have two extra wheels attached to the center of the vehicle body, so that these parts do not normally come into contact with the ground during normal driving. However, by changing the angle using hydraulics, etc., the vehicle can come into contact with the ground. This allows the four wheels to be used to drive onto a trolley, and the remaining two wheels to come into contact with the ground as needed using hydraulics. Alternatively, the trolley can be equipped with a hydraulic jack function, allowing the vehicle to be raised and lowered using hydraulics after it has driven onto the trolley, thereby changing the height of the vehicle's tires and preventing them from coming into contact with the ground. There are several methods for converting the energy of the vehicle's engine or motor into driving energy by attaching a device to the side of the vehicle's tires, etc., to prevent the rotation from coming into contact with the road surface on which the trolley is placed. Another method involves attaching a device to the tires, etc., so that the rotation of the tires does not come into contact with the road surface on which the trolley is placed, while keeping the vehicle's position unchanged during vehicle inspections. This device involves attaching a roller part that rotates in response to the rotation of the tires to the trolley, etc., and connecting it to wheels with a mechanism that converts the rotational energy of the roller part into a mechanism that prevents the trolley's wheels from coming into contact with the road surface. To prevent the road surface, which transmits driving energy, from freezing, water heated to about 15 degrees Celsius by geothermal energy stored 5 meters underground is guided through pipes to the vicinity of the road surface. The water is then collected back into a tank by a motor pump and circulated.For emergency stops, stakes or similar objects may be installed at the rear of the bogie and lowered to the road surface as ...
