[0020] (energy conversion device) An energy conversion device according to one embodiment of the present invention will be described below with reference to the drawings. As shown in Fig. 1, the energy conversion device 1 includes a liquid tank 11, a gas receiver 12, a nozzle 13, a gas cylinder 14, an output means 3, and a recovery device 4. The energy conversion device 1 ejects compressed gas as a primary energy source into the liquid tank 11 storing a liquid 10, and converts the resulting movement energy due to buoyancy 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. The liquid tank 11 stores a liquid 10. The liquid 10 is preferably water, but any liquid can be used. The size of the liquid tank 11 is, for example, 2 to 3 m, but is not limited to this. Inside the liquid tank 11, a power mechanism 31 is installed that generates rotational motion using the buoyancy of the liquid 10. The power mechanism 31 includes a belt 31a arranged in a vertically long ring shape, two upper and lower gears 31b around which the belt 31a is wound, and the gear 31b that rotates as the belt 31a moves. Although the upper gear 31b is submerged in the liquid 10 in FIG. 1, its upper portion may protrude above the liquid surface; for example, nearly the upper half of the gear 31b may protrude above the liquid surface. The amount to be released can be determined appropriately depending on the effectiveness of the buoyancy of the gas in the gas receiving portion 12 and the resistance to the rotation of the gear 31b, for example, the resistance that the liquid 10 exerts on the gas receiving portion 12.

[0022] The gas receiving portions 12 are arranged in a ring shape on the belt 31a, and thus multiple gas receiving portions 12 are provided in the vertical direction within the liquid tank 11. The gas receiving portions 12 are movable up and down in conjunction with the movement of the belt 31a, and rotate at the upper and lower positions, performing an orbital movement between the upper and lower positions as a whole. In this embodiment shown in Fig. 1, the belt 31a and gear 31b rotate rightward, i.e., clockwise.

[0023] The nozzle 13 ejects compressed gas from below the gas receiving portion 12 located at the bottom of the liquid tank 11. The compressed gas is captured by the gas receiving portion 12 and provides buoyancy to the gas receiving portion 12. The gas receiving portion 12 is subject to buoyancy from the liquid 10, but when it moves upward, it receives a greater buoyancy due to the compressed gas ejected from the nozzle 13 than when it moves downward. Although only one nozzle 13 is shown in FIG. 1 , the number is not limited to one, and multiple nozzles may be used. For example, like an upward shower nozzle, multiple openings of the nozzle 13 may be distributed over the entire surface of the downward opening of the gas receiving portion 12, allowing gas to be ejected into the gas receiving portion 12 from a wide area.

[0024] 2(a) and 2(b), the gas receiving part 12 is configured with movable wings 12a that can be opened and closed, and is in an open state when it receives compressed gas ejected from the nozzle 13 and generates buoyancy, and is in a closed state when it does not receive compressed gas and does not generate buoyancy from the gas. This structure allows the gas receiving part 12 and belt 31a to move in an orbit more efficiently.

[0025] Gas cylinder 14 stores compressed gas as a primary energy source and delivers the compressed gas to nozzle 13. Gas cylinder 14 sprays the compressed gas from nozzle 13 via valve 14a, which is controlled to open and close. Valve 14a is controlled to open only when gas receiving portion 12 reaches a predetermined position. This allows the compressed gas to be efficiently captured in gas receiving portion 12, thereby reducing consumption of compressed gas and preventing air bubbles from mixing with liquid 10, thereby maintaining a high density of liquid 10 and making effective use of the inherent buoyancy of liquid 10.

[0026] The gas cylinder 14 is connected to a compressed gas generator 5 that generates compressed gas. The compressed gas generator 5 may be, for example, a general compressor that compresses gas by the rotational motion of an impeller or rotor or the reciprocating motion of a piston, thereby converting mechanical energy into the energy of the gas, which is a fluid. The compressed gas generator 5 is operated by power from a power source 50. Natural energy, such as wind power, geothermal power, hydraulic power, tidal power, or wave power, is preferably used as the power source 50 in order to suppress the generation of greenhouse gases.

[0027] The compressed gas generated by the compressed gas generator 5 is gas with increased pressure so that the gas can be supplied from the nozzle 13 to the gas receiving portion 12 against the water pressure of the liquid 10 in the tank 11. The gas supplied to the gas receiving portion 12 is supplied to give buoyancy to the gas receiving portion 12 by the liquid 10.

[0028] The output means 3 is a means for outputting the kinetic energy of the upward movement due to buoyancy generated in the gas receiving portion 12 as secondary energy to the outside of the liquid tank 11. In the present embodiment shown in Fig. 1, the output means 3 includes a power mechanism 31 that converts the kinetic energy due to buoyancy into rotational energy of the rotation shaft 31c of the gear 31b, and a power generation device 32 that converts the rotational energy of the rotation 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 in which the gas accumulates. The recovery device 4 sends the gas that accumulates in the gas chamber 15 to the gas cylinder 14 via the compressed gas generator 5. The gas in the gas chamber 15 includes the gas generated from the nozzle 13 and the vapor of the liquid 10.

[0030] The recovery device 4 is equipped with a three-way valve 41, a sub-cylinder 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 valves for adjusting the flow rate and closing the gas, which are controlled to open and close. These are preferably multi-function 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-cylinder 40 functions as a buffer to supplement the capacity of the gas chamber 15.

[0031] Furthermore, when the compressed gas generator 5 has the functions of the three-way valve 41, the sub-cylinder 40, and the valve 42, the recovery device 4 may be configured only with piping connecting the gas chamber 15 and the compressed gas generator 5.

[0032] Next, the operation of the energy conversion device 1 will be described. The operating gas, i.e., compressed gas, of this device will be described as air, but is not limited to air. The liquid 10 will also be described as water. Water is poured into the liquid tank 11 in which the power mechanism 31 is installed, and piping such as a gas cylinder 14 is connected to the nozzle 13. The piping of the recovery device 4 is connected to the gas chamber 15, and the compressed gas generator 5 is operated to prepare compressed gas. The gas pressure in the gas chamber 15 is adjusted with the three-way valve 41, and the compressed gas is sent to the nozzle 13 while adjusting the valve 14a.

[0033] The gas constituting the compressed gas coming out of the upward opening of the nozzle 13 is captured by the gas receiving section 12 that opens at the bottom of the upwardly moving belt 31a, and replaces the water in the space above the gas receiving section 12. Then, buoyancy due to the gas is applied to the gas receiving section 12, which creates a difference in the forces acting on the left and right belts 31a due to the buoyancy of the liquid 10, and the belts 31a gradually begin to rotate clockwise. When the gas is received by the gas receiving sections 12 that move one after another above the nozzle 13, the circular movement of the belts 31a reaches a steady state.

[0034] When the belt 31a is in a steady state of rotation, gas is released from the gas receiving section 12, which rotates together with the belt 31a in contact with the upper gear 31b. After releasing the gas, the gas receiving section 12 moves downward with the openable and closable movable wings 12a closed. When the gas receiving section 12, which rotates together with the belt 31a in contact with the lower gear 31b, reaches a position above the nozzle 13, the openable and closable movable wings 12a open, and the gas is received from the nozzle 13.

[0035] The circulating belt 31a converts the kinetic energy from the gas receiving part 12, which rises due to buoyancy, into rotational kinetic energy of the gear 31b. The rotation of the gear 31b rotates the rotation shaft 31c, and this rotational energy becomes electrical energy generated by the power generator 31 and is taken out to the outside. Of course, this energy can also be used directly to drive gears, etc., to turn the ship's screw.

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

[0037] The compressed gas generator 5 compresses the gas to a pressure P1 that is at least equal to or greater than the water pressure PW in order to obtain the required pressure P1. 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 formula is satisfied.

[0038] In this energy conversion device 1, compressed gas circulates as a working gas within the device while undergoing pressure fluctuations. In a steady state, the energy conversion device 1 forms a closed circulation circuit for the working gas. In order to adjust the pressure of the working gas, various parts such as various valves, pressure sensors, and tanks may be incorporated into the energy conversion device 1 as appropriate.

[0039] According to this energy conversion device 1, compressed gas as a primary energy source is ejected into a liquid tank 11 storing a liquid 10, the resulting movement energy due to buoyancy is converted into secondary energy, and the gas is recovered from the liquid tank 11 into a gas cylinder 14 for reuse. This makes it possible to generate and convert energy efficiently. When a special gas other than air or the like is used as the working gas, i.e., the compressed gas, the special gas can be recovered and reused. Furthermore, since the gas in the gas chamber 15 is not released into the atmosphere, for example, the gas pressure P2 in the gas chamber 15, i.e., the gas pressure energy, can be reused.

[0040] Next, another embodiment will be described with reference to Fig. 3. The energy conversion device 1 of this embodiment includes 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 Fig. 1. In this example, the liquid tank 11 is installed underground, but it is not limited to being installed underground and may be semi-underground or above ground. The same applies to the energy conversion device 1 of Fig. 1.

[0041] The transmission mechanism 30 includes a coupler 3a, such as a gear, that engages with the lower gear 31b of the power mechanism 31 to receive its rotational energy, and a shaft 3b, a coupler 3c, a shaft 3d, a coupler 3e, and a shaft 3f that are sequentially coupled to the coupler 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 located to the side of the lower gear 31b. A water seal tank 11A is provided on the side of the liquid tank 11 to surround the coupler 3c and the vertical shaft 3d. The water seal tank 11A has a communication opening 11w that communicates with the interior of the liquid tank 11 and an upper opening 11k that opens upward. The water seal tank 11A contains liquid 10, and the liquid level is open to atmospheric pressure through the upper opening 11k. The vertical relationship between the liquid level of the liquid 10 in the liquid tank 11 and the liquid level of 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-sealed 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-sealed 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 outside the energy conversion device 1 via these couplers 3a, 3c, 3e and shafts 3b, 3d, 3f and transmits it to an 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 wound around upper and lower sprockets 33a and 33b. The rotational energy extracted from the energy conversion device 1 is transmitted as rotational energy to the upper sprocket 33a via a shaft 3f.

[0046] According to this energy conversion device 1, energy based on the pressure of compressed gas can be converted into mechanical energy and output, and therefore the mechanical energy can be used as is as energy for the mechanical operation of the operating device 33.

[0047] Next, with reference to Figures 4, 5, and 6, an example of a combination in which a plurality of liquid tanks 11 are used will be described. A plurality of liquid tanks 11 may be provided in parallel or in series with respect to a 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 provided in parallel with respect to a gas cylinder 14. Compressed gas is delivered to the nozzle 13 of each liquid tank 11 via a respective valve 14. Furthermore, the gas in the gas chamber 15 of each liquid tank 11 is recovered in a sub-cylinder 40 via a respective three-way valve 41. The liquid tanks 11 arranged in parallel do not have to have the same structure, but may have different structures, and the number of liquid tanks 11 is not limited to three.

[0048] The energy conversion device 1 shown in FIG. 5 shows an example in which three liquid tanks 11 of the same structure are installed in series with respect to a gas cylinder 14. The liquid tanks 11 are arranged at the same horizontal level. Compressed gas is delivered 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 delivered from the gas chamber 15 of the first liquid tank 11 via a three-way valve 41 to the nozzle 13 of the second liquid tank 11. Gas is delivered from the gas chamber 15 of the second liquid tank 11 via a three-way valve 41 to the nozzle 13 of the third liquid tank 11. Then, gas is collected from the gas chamber 15 of the third liquid tank 11 in a sub-cylinder 40.

[0049] The valve 14a and the three three-way valves 41 are used to adjust the pressures corresponding to the above-mentioned 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 of tanks is not limited to three.

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

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

[0052] Next, an example of a compressed gas generator 5 will be described with reference to Figures 7(a) and (b). This compressed gas generator 5 generates compressed gas by pressurizing gas using a pressurizing piston 52 provided in a cylinder 51. The pressurizing piston 52 includes a piston body 52a and a seal member 52b made of a life-ring-like O-ring that can adjust the internal pressure.

[0053] A pipe for producing compressed gas is connected to an opening in the lower side wall of the cylinder 51. The pipe is connected to the gas cylinder 14 via a three-way valve 51a. The lower part of the cylinder 51 is connected to a water seal tank 11A provided outside the side wall of the cylinder 51 by a water seal structure. A chain is fastened to the underside of the pressurizing piston 52, and the chain passes through the water seal structure and is fixed to a hoist 53 located above the water seal tank 11A so as to be able to be freely wound up and unwound.

[0054] 7(a), in the pressurizing step, the internal pressure of the life-ring-shaped seal material 52b is increased to form 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 winch 53 to compress the gas inside the cylinder 51 and send the compressed gas to the gas cylinder 14.

[0055] 7(b), in the intake process, the internal pressure of the life-ring-shaped sealing material 52b is weakened to create a gap between the pressure piston 52 and the inner wall of the cylinder 51. Next, the winch 53 is loosened to pull the pressure piston 52 upward, and gas is sucked into the cylinder 51.

[0056] The mechanism and energy for pressing down the pressure piston 52 to compress the gas are not limited to those using the hoist 53, and various methods can be used. For example, instead of using the water-sealed structure and the hoist 53, a configuration in which oil pressure or water pressure is applied to the upper surface of the pressure piston 52 may be used. The intake process can be easily performed by lowering the internal pressure of the life-ring-shaped sealing material 52b, the internal pressure of which can be adjusted.

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

[0058] Next, another example of the energy conversion device 1 will be described with reference to Fig. 9. In this energy conversion device 1, a compressed gas generator 5 generates compressed gas by passing a gas pipe through a heat exchanger 54 to heat the gas, and the rest is the same as the energy conversion device 1 of Figs. 1 and 3. On the upstream side of the heat exchanger 54, i.e., on the sub-cylinder 40 side, there is a valve 42 that functions as a check valve. Furthermore, on the downstream side of the heat exchanger 54, i.e., on the gas cylinder 14 side, there is provided a three-way valve 51a for adjusting the gas pressure, etc., as needed.

[0059] In this compressed gas generator 5, a heat medium 54a that becomes high temperature is sealed inside the housing of a heat exchanger 54. The piping that guides the working gas that circulates within the energy conversion device 1 to operate the energy conversion device 1, i.e., the gas that becomes compressed gas, is surrounded by the heat medium 54a within the heat exchanger 54. The working gas inside the piping receives heat from the heat medium 54a and is gasified into a high-pressure compressed gas. The working gas does not need to be in a gaseous state at all times while circulating within the energy conversion device 1, and may be in a liquid or solid state. When a working gas in a state other than a gas is collectively referred to, it is called a working gas material.

[0060] The heat exchanger 54 may be, for example, a solar water heater, in which metallic sodium is enclosed as the heat medium 54a having a high boiling point. The heat exchanger 54 may use natural energy to heat the heat medium 54a. The natural energy may be, for example, solar energy, geothermal energy (such as heat from magma), or heat from a hot spring.

[0061] The substance that becomes the working gas may be arbitrarily selected depending on the combination with the liquid 10 in the liquid tank 11, and further depending on the operating conditions of the energy conversion device 1, such as the various pressures P1, PW, and P2, the temperature conditions of the liquid 10, and the physical properties during operation. For example, a refrigerant such as chlorofluorocarbon may be used as the working gas. Furthermore, ammonia water may be used as the liquid 10 in addition to water.

[0062] Next, referring to Fig. 10, a schematic description will be given of the circulation process of the working gas in one embodiment of the energy conversion device 1. In the energy conversion device 1 of this embodiment, the working gas is made 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 into the sub-cylinder 40, and returned to the compressed gas generator 5. The main body 11R is a collective term for the liquid tank 11 and the entire structure therein, and includes components for converting the primary energy of the compressed gas into kinetic energy and then outputting it outside the liquid tank 11 as secondary energy.

[0063] The compressed gas generator 5 of this embodiment includes a compressor 16, a heat exchanger 17, and an evaporator 18. Here, the description will be made assuming that the working gas is chlorofluorocarbon, which is used as a refrigerant in refrigerators and the like. Such a working gas can be used as a heat source when heated to a high temperature, can be used as a heat source when cooled by expanding and emitting heat of vaporization, and can also be used as a gas that provides buoyancy to the gas receiving section 12 in the energy conversion device 1 when made into a high-pressure gas.

[0064] The compressor 16 compresses the working gas using, for example, electrical energy to create a high-temperature, high-pressure state. The heat exchanger 17 releases the heat from the working gas and heats liquids or gases such as water or air. The heated liquid or gas is then guided to another location and used for heating in an air conditioner or the like.

[0065] The vaporizer 18 expands the working gas through an expansion valve and further cools it. The cooled working gas can absorb heat from its surroundings, and its heat absorption capacity is used to build air conditioning systems. The working gas that passes through the heat exchanger 17 and vaporizer 18 becomes a compressed gas with an appropriately adjusted pressure, and is sent to the device main body 11R via the gas cylinder 14 for energy conversion.

[0066] According to this circulation process, surplus energy is first input into the working gas in the compressor 16, and then the surplus energy is used for heating and cooling in the subsequent heat exchanger 17 and evaporator 18, respectively, and then energy conversion using buoyancy is performed. In an environment where surplus energy can be input, a unified system as a whole can be constructed.

[0067] Next, another embodiment of the energy conversion device 1 will be described with reference to Fig. 11. In the energy conversion device 1 of this embodiment, the power mechanism 31 in the energy conversion device 1 of Fig. 1 is replaced with a power mechanism 31A having the form of a water wheel. The power mechanism 31A has a plurality of gas receiving portions 12 provided around the outer periphery of a rotor that rotates around one axis. The gas receiving portions 12 have the structure shown in Figs. 2(a) and (b).

[0068] In this embodiment, two clockwise rotating power mechanisms 31A are installed in the liquid tank 11. Each power mechanism 31A is provided 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 body movement device) Next, a vehicle body moving device according to one embodiment of the present invention will be described with reference to the drawings. As shown in Figures 12(a) and 12(b), the vehicle body moving device 2 includes 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 a road surface 20 and having ice surfaces 2a formed by freezing a liquid to guide the sleds 22 as they slide on the ice, and a drive unit for driving the vehicle body 21.

[0070] Rail 23 has a housing 23a with a concave cross section formed with a longitudinal groove and fixed to road surface 20, and refrigerant pipes 23b arranged inside the grooves for passing a refrigerant. Water is poured into the grooves of housing 23a and cooled by refrigerant pipes 23b to form ice 2b. The surface of ice 2b becomes ice surface 2a when sled 22 slides on the ice. Rail 23 may be provided with a cover to prevent rain and other elements from entering the interior when sled 22 is not sliding on the ice, and may also be provided with a drain hole to drain water present on ice surface 2a. This cover and housing 23a of 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 car body 21 so that it travels along the rail 23. Such a guiding device may be provided between the sled 22 and the rail 23. For example, a structure on the rail 23 may be configured to enclose and surround the sled 22 so that the sled 22 does not deviate from the rail 23.

[0072] The drive device is 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, and when not driven, they are moved upward so as to move away from the road surface 20, and the vehicle body 21 travels on the ice surface 2a using sleds 22 (Fig. 12). When driven, the wheels 24 come into contact with the road surface 20 and cause the vehicle body 21 to travel (Fig. 13).

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

[0074] The car body moving device 2 may be an embodiment in which the car body 21 is moved by using a drive unit that does not have wheels 24. For example, a jet propulsion unit or a propeller propulsion unit may be mounted on the car body 21 as the drive unit. A linear motor may also be used as the drive unit. In this case, the track that forms the magnetic field of the linear motor may be covered with a frozen liquid to form an ice surface. The drive unit may also be a combination of a linear motor and wheels 24 that obtain drive force from an engine or motor mounted on the car body 21.

[0075] A braking device according to one embodiment of the vehicle body moving device 2 will be described with reference to Figures 14(a) and (b). The vehicle body 21 sliding on ice on rails 23 using a sled 22 has its kinetic energy absorbed by the braking device, causing it to slow down or stop. The vehicle body moving device 2 can be equipped with any braking device. The braking device 25 of this embodiment absorbs kinetic energy by the movement resistance of a fluid. 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 that is provided on the lower part of the vehicle body 21 and engages with the locking portion 26c. The cylinder 25a and the piston 25b have the structure and function of a shock absorber. Furthermore, pairs of cylinders 25a and pistons 25b are arranged at predetermined intervals along the rail 23. The pairs of cylinders 25a and pistons 25b may be arranged at predetermined intervals along the entire length of the rail 23, or may be arranged at predetermined intervals within a predetermined range.

[0077] Engagement portion 21b is movable up and down, and when braking, is lowered from traveling vehicle body 21 to be engaged with engagement portion 26c, pushing engagement portion 26c in the traveling direction (leftward in the figure). This pushes piston 25b to move leftward, and kinetic energy is converted into and absorbed in thermal energy by the viscous resistance of the oil, decelerating vehicle body 21.

[0078] The braking device 25 is equipped with multiple safety valves 25d for releasing pressure in the cylinders 25a to prevent breakdown. These safety valves 25d are set to function in stages according to the pressure levels. If the vehicle body 21 cannot be stopped within the movable range of the pistons 25a, the engagement between the locking portion 26c and the engaging portion 21b is automatically released, and the engaging portion 21b is engaged with the locking portion 26c of the next pair of cylinders 25a and pistons 25b in the traveling direction, and braking operation is performed by that pair. The braking device 25 is set and positioned according to predetermined rules regarding traveling speed and braking distance.

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

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

[0081] The structure 60 has a cavity 61 formed therein by connecting and communicating multiple hollow tubes 6a made of a light-transmitting material. The cavity 61 is used as an air-conditioning space or a space for installing energy exchange equipment. The structure 60 may be installed above ground when used in the presence of sunlight, for example, or underground in other cases. If installed underground, it becomes easier to use it at a predetermined constant temperature. The structure 60 is used as an enclosed 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 by leaving part of both ends open.

[0082] The pipe 62 and the circulation pump P3 are used to circulate constant-temperature groundwater stored in the underground tank T and pumped up by the 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. The fan 63 generates an air flow in the sealed cavity 61 formed by the structure 60. This airflow eliminates stagnation of air within the cavity 61. The structure 60 may be equipped with external piping from one end to the other to form a closed air passage, and the fan 63 may generate a unidirectional air flow within the structure 60.

[0083] As shown in FIG. 16 , the cavity 61 is suitable for use 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, four sides of which are maintained at the temperature of groundwater. Air is blown through the cavity 61 by a fan 63, so that the panel surface can be kept at a low temperature and power generation efficiency can be maintained. The shape of the cavity 61 in the structure 60 can be appropriately designed to optimize and efficiently control the temperature of the contents to be stored therein. For example, in the case of the solar panel 64 shown in FIG. 16 , the cavity 61 may be sealed by being surrounded by walls formed by hollow tubes 6a adjacent to the outer periphery of the panel, including the front and back surfaces, so that the panel can be stored in the smallest possible space. Alternatively, the cavity 61 may be partially open and unsealed.

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

[0085] Next, an energy utilization device 6A according to another embodiment of the present invention will be described with reference to FIG. 18. The energy utilization device 6A utilizes constant-temperature underground energy and includes a hollow pipe 65 that travels back and forth between the surface and a predetermined depth underground where the temperature is constant, and a fan 66 that sends air from the surface into the hollow pipe 65. The air sent into the hollow pipe 65 by the fan 66 undergoes heat exchange by absorbing or emitting heat at the predetermined depth underground, and is cooled or heated. The cooled or heated air can then be used for air conditioning on the surface. To facilitate heat exchange underground, the surface area of ​​the piping may be increased by providing multiple fins on the piping or by forming multiple branched piping. Although it varies depending on the latitude, in Honshu, Japan, the ground temperature is maintained at about 15 degrees Celsius at 5 meters underground throughout the year. Taking advantage of this property, for example, a tank is installed about 5 meters underground and water is stored there. The temperature is then transferred to the desired location, such as above ground, using pipes, and the water is cooled in the summer and warm in the winter. This is similar to a system constructed by connecting plastic bottles. It can also be made to flow through a structure. If a space is provided around the path of the flow of a liquid, the air there will be closer to the temperature of the surrounding flowing liquid. The path of the space can be configured to be as long and narrow as possible to ensure efficient heat exchange (Figure R1).

[0086] Next, an energy utilization device 6B according to yet another embodiment of the present invention will be described with reference to Figure 19. The energy utilization device 6B is a device that utilizes sunlight energy and includes a structure 60 formed by connecting and communicating a plurality of hollow tubes 6a made of a light-transmitting material to form a cavity 61 therein, 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 into the cavity 61 formed by the structure 60 from one opening thereof toward the other opening.

[0087] The structure 60 is installed in a place where it can receive sunlight, and seawater 9 is passed through the bottom side of the hollow portion 61 in a plan view, and air is blown over the seawater 9 by a fan 63. This promotes evaporation of the seawater 9, and salt can be obtained.

[0088] Next, an energy utilization device 6C according to yet another embodiment of the present invention will be described with reference to Fig. 20. The energy utilization device 6C utilizes compressed air for air conditioning, and includes an air compressor 68 powered by natural energy, and an underground tank Ta for storing the air compressed by the air compressor 68. In this example, solar panels 64 are provided to use sunlight as the natural energy.

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

[0090] Next, an energy utilization device 7 according to yet another embodiment of the present invention will be described with reference to Fig. 21. The energy utilization device 7 generates electricity using natural energy and includes a wall structure 71 installed on a coast that simulates a ria coast where the force of ocean waves causes seawater to rise above sea level, a tank 72 that introduces and stores the risen seawater 70 using 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] Seawater waves crashing onto the shore are narrowed by a funnel-shaped wall structure 71, and run up the slope, causing seawater 70 to flow into a tank 72. Once the seawater in the tank 72 begins to flow toward a hydroelectric generator 74 via pipes 73a and 73b and a pump 73, the flow downstream continues without the need for a pump.

[0092] By providing an air compressor instead of the hydraulic generator 74, instead of generating electricity, potential energy can be used to generate compressed air and store it in a tank, thereby storing the potential energy as pressure energy.

[0093] A substance that vaporizes under pressure, such as dry ice, is placed in an airtight container, and a fluid liquid is then placed inside. The difference in specific gravity between the two creates an upward movement of gas, which would occur on land. This energy is used to move blades or other devices set inside the container. The blades convert the energy into rotational energy, which is then extracted via gears or shafts and used as power. This technique utilizes a change in the state of matter. Vaporized dry ice (just one example; any substance with similar properties will do) is then transported through a sealed tank or other similar container to another tank. Internal pressure can be adjusted by installing an on-off valve in a sealed tank. Multiple sealed tanks can be connected. However, if too many tanks are connected, the pressure of the dry ice or other substance may not decrease, preventing it from vaporizing. The vaporized dry ice or other substance is eventually collected from the end of the tank via a pipe or other means. It is then repressurized and sent to the first tank in dry ice, vaporized, or liquid form. During this process, solids have a smaller volume per unit mass, making them easier to transport into a sealed tank. A pressurized device is installed to turn dry ice (which has vaporized) back into a solid or liquid state. This device is sealed so that work can be done without releasing dry ice or other gases outside. Therefore, dry ice does not leak outside (such as into the atmosphere). Energy can be obtained by connecting devices like this and assembling a device like this. To send dry ice or other liquids in solid or liquid form, it is easy to imagine sending dry ice in the same way as a bicycle pump. This is just one example. Imagine that when you pump air into a bicycle, you connect the tire to the pump, pack dry ice (solid, liquid, gas) into the pump in a sealed state, then send it into the tire, and the dry ice (gas, etc.) is returned from the tire to the pump. In reality, when returning the dry ice (gas, etc.) to the pump, it is first pooled in a sealed state using a pressurized device, and then gradually returned to the pump (the part corresponding to the sealed container) while adjusting the pressure. Sensors to measure pressure can be installed as needed.If dry ice or other liquids are pressurized and in a solid or liquid state, they will not suddenly disperse when exposed to the atmosphere, so you don't have to worry too much about it and can be placed in an air pump (equivalent to an airtight container) with only a small loss of air. When a light object (such as a gas) is combined with a heavier object (such as a liquid) and placed in a certain location, the difference in mass causes the object to move in a specific direction. This energy can be extracted and used as an energy source to operate other machines. A light material (for example, carbon dioxide as a gas) and a heavy material (for example, water) are prepared and placed in a sealed tank. The water is placed in the tank beforehand through a pipe from the outside. The pipe has an opening and closing mechanism, so that when the faucet is closed, the water in the tank does not leak out. Then, dry ice (solid carbon dioxide) is transferred from another pipe into the sealed tank from a separate, sealed space without coming into contact with the outside air. Once inside the tank, the pressure drops and the dry ice evaporates, and the gas moves to the top of the tank. The gas that moves to the top travels through a pipe to a second tank with a similar structure. It then travels through the tank again, going up. There are pipes at the top of the tank, through which the carbon dioxide is guided to a specific location. The pipes are then connected to a compressor, which turns the carbon dioxide into a solid or liquid again. It can then be refilled through the inlet of the first tank. Naturally, it is also possible to install openings and closing doors and various monitoring devices to measure and adjust the pressure inside the tank, and monitor it using a computer, etc. If three sealed tanks are prepared, solid carbon dioxide (you can choose to inject it as dry ice, liquid carbon dioxide, or gas) can be injected into the inlet of the first tank, and the vaporized carbon dioxide can be collected from the third tank, and then it can be pressurized again and returned to the inlet of the first tank. The key point is that the difference occurs when dry ice (or anything with similar properties) vaporizes and moves through water, and the energy obtained by capturing and extracting it as energy is compared to the energy used to turn carbon dioxide or other gases into a solid, or to return it to the tank under a certain pressure without turning it into a solid, because the difference does not include the energy from gravity. The same effect occurs when gravity is simulated. The various substances mentioned in this document do not have any particular effect on the operating principle as long as they produce similar effects in terms of their properties. The present invention is not limited to the above-described configuration, and various modifications are possible. For example, the configurations of the above-described embodiments may be combined with each other. The following is an excerpt from the basic application from which priority is claimed: For example, for transporting objects, the wheels of a train are replaced with sleds, etc. Instead of railroad tracks, a space just wide enough for a sled to pass through is provided, and water or other materials is placed in that area, and electricity or other means is used to cool and freeze the sled, thereby reducing friction and minimizing energy loss. Wheels or other materials are placed in contact with the gaps between the rails and are used during acceleration and deceleration. These wheels or other materials can also be retracted into the car body using electricity or other means to prevent them from coming into contact with the ground when the car gains speed, reducing resistance. The sled slides on frozen road surfaces, but has a rail structure with a protruding shape to prevent it from slipping off the rails sideways. Tires or other materials that come into contact with the side of the rails can be attached to the sled to reduce impact on curves, etc. The route can be designed to slope downwards gradually, using gravitational energy and other factors to provide acceleration. While it's possible to design a route with no elevation difference, even in cases where construction costs are considered and an uphill route is chosen, sleds reduce friction, allowing inertial energy to be used as the source of energy to move objects to higher ground. Even on a slight downward slope, resistance at the contact points of the vehicle body is extremely low, allowing vehicles to rapidly accelerate with only a small amount of energy provided by the tires in contact. The same is true for vehicles that are not in contact with the ground, such as linear motor cars. Air resistance can also be prevented by creating as much of a vacuum as possible inside the tube or tunnel surrounding the vehicle. Possible methods include opening hatches on the vehicle when it arrives at a station, creating a connecting passageway to the outside, or installing partition hatches or other doors within the tunnel that can be opened and closed vertically to partially inflate the air at sections such as stations, allowing passengers to enter and exit. If rainwater or other liquids get into the structures above the lane, which are cooled and kept at a temperature that minimizes resistance, hollow holes are provided at the ends of the lane, allowing them to drain quickly. A roof can be added to the top to prevent rainwater from entering, or the entire surrounding area can be shielded. To shield the structure, transparent, light-transmitting materials or strong plastic can be used, or a structure made of connected plastic bottles (or other specialized bottles) can be used to circulate water from an underground tank located about 5 meters underground in a place that is maintained at about 15°C year-round (e.g., underground in mountainous areas, there is natural gravity to allow the water to fall). This will keep the space through which vehicles travel closer to 15°C, and by adjusting the liquid flow rate, it will be possible to reduce air conditioning costs. When reducing the pressure in the space through which vehicles travel to a vacuum-like state to reduce air resistance, the perimeter of the space through which vehicles travel can be reinforced with pressure-resistant reinforced plastic or glass. When circulating water or other liquids using a pump, the pump does not have to be operated frequently because liquids such as water will not suddenly boil even when exposed to sunlight from outside, and energy costs are low.If energy is obtained from solar panels, they are installed on the roof or in open spaces such as the sides or lanes of the facility. To cool the solar panels, water maintained at a constant temperature in an underground tank like the one described above is flowed over the panels, or a pipe-like structure made of a light-transmitting material is installed nearby, through which water at about 15°C from the underground tank is flowed to control the temperature of the solar panels. Alternatively, the solar panels can be waterproofed and airtight, and attached to a tub or similar object containing shallow water. Water at about 15°C, installed about 5 meters underground, is then flowed into the tub and collected in the underground tank. If the location allows natural groundwater to flow naturally, a free-flowing system is acceptable, and the panel temperature can be controlled. For example, a structure can be constructed using plastic bottles, with the tops cut out to form rectangular cubes, glued together, into which water from the underground tank can be poured. A hollow structure filled with water can be created using a material such as plastic bottles that transmits light but blocks water. Then, the hollow part can be filled with items such as solar panels that need to be temperature controlled. This can be done by installing a similar device on solar panels installed in homes to increase the amount of electricity generated. This is because the amount of electricity generated by solar panels decreases when they get too hot. Also, to efficiently air-condition the space, water at about 15 degrees Celsius from the underground tank mentioned above is used. Since the ground temperature around the underground tank varies depending on the depth, multiple tanks can be installed at different depths, and the water can be mixed. Water, etc., which has been cooled to about 15°C by the ground temperature, is placed inside an underground tank through a pipe about 5 cm long and 5 cm wide (this is only a rough guideline; the scale can be freely adjusted). A structure with a passageway for the water is installed around the pipe, and the water from the underground tank flows through it. A fan or similar device 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, it exchanges heat with the surrounding water (thin materials such as plastic bottles conduct heat easily), gradually cooling it in the summer. If the pipe is made long enough, the temperature at the outlet will approach that of the water from the underground tank. In the summer, it will be cold, and when the air is below about 15°C, it will be warm. For example, a structure can be created by connecting plastic bottles, etc. Fans, etc., consume little power, making them energy-efficient. The pipe does not need to be straight; it can be curved to increase the distance. Thinner pipes can also be inserted inside the pipe to allow water to circulate through them, facilitating heat exchange when exposed to cold. By placing metal rods with high thermal conductivity between the pipe and the passageway through which circulating water flows, the surface area of ​​contact between the water (around 15°C) and the flowing air can be increased. Fans can also be installed not only at the pipe inlet but also at the outlet or along the way to increase heat exchange efficiency. This device can be installed indoors or in places with a constant ground temperature, such as 5 meters underground. Air is pumped in and out through pipes. By pumping air through a pipe at a depth of around 5 meters underground where the ground temperature is around 15°C, the air drawn in above ground in summer will circulate underground and exit the pipe at a temperature close to the ground temperature of 15°C, even in winter. This is the same regardless of the season. Water flows on all four sides or through a specific section of the pipe. In a two-tiered structure, the lower section can be maintained by gravity without the need for a ceiling, allowing the water to come into direct contact with the air, improving heat exchange efficiency. If the ground temperature around the pipe is around 15°C in most of the installation location, the temperature of the original air will approach 15°C. Compressed air is used when hot spring water or water artificially boiled in a boiler is used for air conditioning in homes and facilities.First, hot water is poured into a space made of plastic bottles, etc., and the above method utilizes the underground temperature of approximately 15°C to exchange heat and bring the air temperature closer to 15°C. However, instead of 15°C, hot water can be added to achieve that temperature. To keep the air warm while it is being sent, the bottles are placed inside a connected pipe, enclosed by the pipes, and the air is sent in a compressed state (or just a slight breeze, depending on the situation). The space for sending hot air can be installed underground or above ground, but if the surface is very cold, considering the cost of digging underground, an insulation system can be used, using water from a tank about 5 meters underground at approximately 15°C. Since underground tanks vary in depth depending on the season, multiple tanks can be used and water can be mixed. If necessary, the outside of the device sending the air made from plastic bottles can be covered with insulation (such as insulating material like styrofoam) to increase efficiency. Cold air can also be sent. By connecting plastic bottles, etc., a certain rectangular space is created, and then other plastic bottles are connected inside it to create a structure. Then, as mentioned above, liquids can be poured in, and items that need to be dried or moistened are placed in the space where air was blown in the above. At this time, it is possible to pack it tightly so that the air does not get delayed, or there can be some gaps so that warm air can be blown in. For example, when evaporating seawater to extract salt, etc. A space containing seawater is constructed, above which a space for hot air to flow is created. Below that, a plate-like passageway (which can be slightly inclined) made from plastic bottles or other materials is created, and above that, a space for water to flow is created. The outer perimeter can be surrounded by plastic bottles or other materials, and the entire interior can be pressurized with a compressor or other device. The evaporation of seawater is accelerated by the power of sunlight or by flowing hot water, further accelerating the process by sending in hot air or other materials. When the humidity increases, the interior pressure, which has been pressurized by the compressor, is returned to normal, and cold water from an underground tank or other source is passed through the pipes. When the humidity decreases and the nearby temperature cools, water droplets suddenly escape from the air, flowing over the installed plate and moving to the lowest point. This structure can speed up the evaporation of seawater or other materials. The outer perimeter made from plastic bottles or other materials can be covered with transparent film or plastic as needed to withstand pressure. When the air inside this device is released to the outside, filters to prevent salt damage can be installed near the outside air intake and exhaust fans. Salt damage is caused by tiny particles generated when waves break and are blown up by the wind, but this device does not generate any tiny particles in the first place, so it was simply installed as a precaution. Hatches are installed in ventilated areas to ensure that the device can withstand pressure when the inside is pressurized. By making this device out of transparent materials such as plastic bottles, the power of sunlight can be transmitted efficiently. By laying a black material (such as a black sheet) at the very bottom of the device, the energy of sunlight can be used even more efficiently. This device can be installed in a space that requires sunlight, such as a solar panel, and salt can be obtained while preventing the solar panel from overheating. The angle of the device can be adjusted by creating a base out of transparent materials such as plastic bottles at the bottom depending on the installation angle of the solar panel. When raising fish, the space should be loop-shaped to prevent the fish from accelerating in a direction close to vertical and colliding with the walls of the space containing water. As shown above, a space is created using a plastic bottle or similar and water is poured into it. A lid can also be made from a plastic bottle or similar material for the top. Then, a pump can be used to suck out the water inside and spray it out under pressure, or compressed air can be sent in one direction to rotate the water in a certain direction. The width of the loop structure where the fish swim should be about 50 to 100 centimeters (this is just a guideline). Electric compressors are typically used for industrial air compression. These compressors are powered by hydraulic gears or by windmills, which transmit their rotational energy through gears. The compressed air can be stored in a tank about five meters underground at a constant ground temperature, or it can be blown into water in a tank five meters underground to maintain a temperature close to 15°C. By using natural energy, such as hydraulic power, to power an air compressor and storing it in a tank underground, it can be extracted at will, like a battery, and used to power the gears. When compressing air with a compressor, the air can be cooled in an underground tank and then compressed to adjust humidity, or the air can be stored underground to lower humidity. Tanks containing compressed air can also be placed underground to lower their temperature. Even large tanks can be installed underground, making it easy to find a suitable location. Using the above system, compressed air can be adjusted in temperature and humidity, and then transported from the facility to homes through underground pipes, resulting in high efficiency. Rather than storing electricity, it could be stored as compressed air (which could be in gaseous or dry ice form). A waterwheel-like structure could also be installed next to a river. Since ria coastlines can send tsunamis rising to high altitudes, such structures could be artificially created, using the force of ocean waves to bring seawater up to 10 meters or so above the coastline. The water could then be stored and used to power hydroelectric turbines that use gravity to generate electricity or to power air compressors. By utilizing the energy of ocean waves to obtain the potential energy of large amounts of seawater semi-permanently, it could be beneficial to human life. Using this method, compressed air could be stored in a tank or similar and transported 20 meters underground, or the tank could be stationary with a diameter of 20 meters. An underground tank filled with water could then be prepared. A rotating wheel or similar could be installed inside the tank, and compressed air released from below, causing the wheel to rotate using the energy generated when it rises to the surface. The deeper the tank, the more wheels and other components can be installed, and buoyancy will provide the energy to rotate the water wheels and wheels.The rotational energy of the waterwheel or wheel can be used to operate a compressor to generate compressed air or power a generator, making this extremely efficient. Compressed air (gas), dry ice, and Omasa gas (HHO, HSO, etc.) are placed at a deep point under water pressure in a vertical tank filled with liquid water or other liquids. Heat is then applied, either through electricity or a chemical reaction, to ignite the Omasa gas (a mixture of hydrogen and oxygen is also acceptable). The heat causes the dry ice to expand, and the compressed air also generates upward kinetic energy against the water pressure (gravity), which is then used to power a waterwheel or other device, turning it. This energy can be recovered to power a generator. To increase the efficiency of waterwheel rotation, the waterwheel's blades can be made movable and openable. This opens when pushed by the gas, allowing the kinetic energy to be received by the liquid, minimizing the resistance and slowdown in rotation. The blades open and close, but do not close completely, leaving a small gap where air can enter and push them apart. Alternatively, plates can be attached to the blades of the tank's turbine to help the air gather. This blade shape allows a turbine-like device to be installed in a tunnel or other location where there is no energy to lift air or other gases and water pressure. When installed in such a location, the blades open when pushed by the water flow and close when the water pressure weakens. Large-scale dams and other hydroelectric power plants sometimes have heads of 100 meters and hundreds of meters of pipe. However, simply installing a hydroelectric propeller downstream cannot fully capture the energy of the water flow to turn the generator's turbine, resulting in losses. Therefore, the energy can be dispersed into thinner pipe-like tunnels or tubes with heads of around 10 meters, or water turbines or hydroelectric propellers can be installed in sections where there was previously only water flow. This allows for efficient recovery of the potential energy of the water flow. Furthermore, when compressed air or the like is sprayed from deep within where water pressure is high, and the force of the air rising to turn a water wheel or the like is used, if the water tank or tank is designed in such a way that the compressed gas or the like is sprayed at exactly 1 o'clock when the water wheel or the like is rotating clockwise, the deceleration of the propeller, water wheel, etc. due to water pressure can be prevented.Since compressed gas is also ejected from the 6 o'clock direction, etc., a constant clockwise rotational force is maintained, converting the energy of compressed air, gas, etc., and the force of buoyancy due to differences in density, into rotational energy for a water wheel, etc. When injecting compressed gas into a hollow shaft of a water wheel, etc., a stopper or similar device can be installed at the 1 o'clock or 6 o'clock position so that the hole in the shaft catches on it and a door opens, allowing the gas to eject. When the door is no longer caught, it can close with the force of a spring, etc. Alternatively, gas can be passed through the hollow part of the shaft and covered with a metal cap, etc., so that 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. Alternatively, the ejection of compressed gas can be linked to the position of the water wheel, and a valve can be controlled so that compressed gas is only released when the water wheel reaches a specific position. The shaft part that transmits the energy of a water wheel or the like can be extended horizontally to increase airtightness so that water does not leak out of the water tank or tank, and can be passed through to a part of the tank where there is no water, or it can be changed direction using gears inside the tank to transmit rotation to an upward-extending shaft, and 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 to gears again to be used as a power source. Several water wheels or the like can be installed connected vertically. There are various methods that can be considered, such as extending the tank deep underground or raising it above ground. Taking advantage of the natural law that the temperature is maintained at around 15 degrees Celsius approximately 5 meters underground in mainland Japan throughout the year, building a tube-shaped tunnel on the ground there would reduce the energy required for cooling. Alternatively, the structure could be grounded above ground and cooled by covering the outer periphery of the tube with liquid water. If the outer periphery of the tube is made of transparent plastic or glass, it would be possible to see the scenery from inside the vehicle. Similar tunnels could be filled with water and used to run sealed ships, creating a vacuum inside the tunnel and increasing energy efficiency during travel (this could be applied to anything that can travel through a tunnel). Using a similar structure for vehicles, not just large ones like trains, could reduce energy costs, increasing the reliability of autonomous driving. Cars could be connected to carts mounted on a similar platform, with their weight supported primarily by sleds, reducing rolling resistance. There are various methods, such as incorporating a motor or the like into the cart or the like to contact the road surface and transmit power, or connecting the power of the engine or motor of an automobile or the like from the tires, engine, motor, etc. of the automobile or the like to the power section of the cart or the like while the automobile or the like is mounted on the cart or the like, or equipping the cart or the like with a device to transmit the rotational force of the wheels of the automobile or the like to the road surface or the like as needed. Also, even if an existing car or the like is not used, if a four-wheeled vehicle is used, two more wheels or so can be attached to the center of the body in advance, and these parts do not come into contact with the ground or the like during normal driving, but by changing the angle or height using hydraulics or the like, a structure can be created in which they come into contact with the ground, and the four wheels can be used to ride up on the cart or the like, and the remaining two wheels (rubber, steel, etc. wheels) can be used hydraulically or the like to come into contact with the upper part of the cooling rail as needed, or the cart can be given the function of a hydraulic jack, so that after the automobile or the like has mounted on the cart, the car can be raised or lowered using hydraulics or the like to change the height of the car's tires, etc., so that it does not come into contact with the ground or the like. This bogie can be equipped with a motor or the like to provide driving force when running, or some of the bogies can be powered to pull or push and be connected to other bogies like a train, or powered bogies can be appropriately arranged to reduce installation costs.The movement of the trolley (unit) can be monitored with sensors, and cameras can be installed around the cooling lane, allowing the trolley to be controlled automatically and unmanned. Solar panels can be installed near the space where such cooling lanes are installed, and electricity from them can be transmitted from the metal parts of the lane to the motors of the trolleys, or contactless power transmission can be used so that the lane and the electrical receiving part of the trolley do not have to come into direct contact. There are several methods, such as attaching a device to the side of a vehicle's tire to connect to the tire (which can be a steel wheel) so that its rotation does not come into contact with the road surface or the ice-free top of the cooling rail on the trolley, converting the energy of the vehicle's engine, motor, etc. into propulsion energy, or attaching a device to a trolley with a roller part that rotates in response to the rotation of the tire by rotating the engine, etc., without changing the position of the car passing through during vehicle inspection, and connecting it to a wheel with a mechanism that converts the rotational energy of the roller part so that the wheels of the trolley do not come into contact with the road surface. To prevent the road surface from freezing, water stored 5 meters underground and heated to approximately 15 degrees Celsius by geothermal energy is piped to the road surface. The water is then collected by a motor pump and returned to a tank for circulation. For emergency stops, stakes are installed at the rear of the bogie, which can be lowered to the road surface as needed to quickly stop the train. Even when using technologies like linear motor cars to obtain energy in the direction of travel, cooling a portion of the magnetic field on the linear motor car's track to cover it with ice and installing a sled or other device to reduce resistance during travel can save on vertical levitation power and concentrate most of the electrical energy in the direction of travel, making it more efficient. The levitation energy and the energy used to accelerate in the direction of travel are balanced to maximize efficiency by reducing levitation energy and conserving electrical energy as much as possible by adjusting the direction of the applied magnetic energy. Even if the train does not actually float, the sled allows it to reduce resistance and travel. The linear motor car may be equipped with a sled and the powered wheels.The tunnel would be placed in a near-vacuum state, eliminating wind loss and reducing noise. The magnetic energy transfer section of the linear motor car could be installed separately from the sled. To cool the area where the sled comes into contact, a long, thin heat-absorbing plate from a freezer could be installed there, or a dedicated heat-absorbing device could be installed. Efficient temperature control could be achieved using a large compressor and constant-temperature underground water. The waste heat from the compressor could be used to power a Stirling engine. The compressor could be placed in a space where water drawn from 5 meters underground is circulated around it using pipes. Even for existing roads, to prevent freezing and lower road surface temperatures in the summer, water stored in tanks installed 5 meters underground beneath roads and walkways could be circulated 10 cm below the asphalt using pipes to prevent the road surface from freezing or overheating. Circulating water could also be piped around the sled, improving cooling efficiency in the summer. Using plastic bottles or other materials, create a space the size of a futon (the size can be adjusted to suit your needs, whether larger or smaller), keeping the space cool in the summer and above freezing in the winter. Water from a tank installed about 5 meters underground is poured into the bottles through pipes, and the bottles are connected so that the water circulates and returns to the tank. Water can be pumped using a motor, installed underground on a high mountain, or connected to a large-scale facility such as a water purification plant, and a cool tank can be maintained at a temperature of approximately 15°C even in the summer, allowing water to be pumped using only water pressure. Cooling rails (lanes) can be covered with airtight structures and circulated with water from underground tanks at around 15°C, reducing the cost of cooling towers. The top covers of cooling rails and lanes are typically closed electrically in the summer to minimize heat buildup, but they can also be automatically opened and closed by a motor when a sensor detects the passage of vehicles. When freezing liquids such as water inside a cooling lane, compressed air (carbon dioxide) or gas can be sent through pipes that run through the liquid or ice, allowing for cooling using the latent heat of vaporization. For example, for transporting objects, the wheels of a train are replaced with sleds, etc. Instead of railroad tracks, a space just wide enough for a sled to pass through is provided, and water or other materials is placed in that area, and electricity is used to cool and freeze the water, thereby reducing friction and minimizing energy loss. Wheels or other materials are placed in contact with the gaps between the rails and are used when accelerating or decelerating. These wheels or other materials can also be retracted into the car body using electricity or other means to prevent them from coming into contact with the ground, etc., in order to reduce resistance when the car gains speed. The sled slides on the frozen road surface, but has a rail structure with a protruding shape to prevent it from running off the side. Tires or other materials that come into contact with the side of the rails can be attached to the sled to reduce impact on curves, etc. The route can be designed to slope downwards gradually, using gravitational energy and other factors to provide acceleration. While it's possible to design a route with no elevation difference, even in cases where construction costs are considered and an uphill route is chosen, sleds reduce friction, allowing inertial energy to be used as the source of energy to move objects to higher ground. Even on a slight downward slope, resistance at the contact points of the vehicle body is extremely low, allowing vehicles to rapidly accelerate with only a small amount of energy provided by the tires in contact. The same is true for vehicles that are not in contact with the ground, such as linear motor cars. Air resistance can also be prevented by creating as much of a vacuum as possible inside the tube or tunnel surrounding the vehicle. Possible methods include opening hatches on the vehicle when it arrives at a station, creating a connecting passageway to the outside, or installing partition hatches or other doors within the tunnel that can be opened and closed vertically to partially inflate the air at sections such as stations, allowing passengers to enter and exit. Taking advantage of the natural law that the temperature is maintained at around 15 degrees Celsius approximately 5 meters underground in mainland Japan throughout the year, building a tube-shaped tunnel on the ground there would reduce the energy required for cooling. Alternatively, the structure could be grounded above ground and cooled by covering the outer periphery of the tube with liquid water. If the outer periphery of the tube is made of transparent plastic or glass, it would be possible to see the scenery from inside the vehicle. Similar tunnels could be filled with water and used to run sealed ships, creating a vacuum inside the tunnel and increasing energy efficiency during travel (this could be applied to anything that can travel through a tunnel).

Cars could be connected to carts mounted on a similar platform, with their weight supported primarily by sleds, reducing rolling resistance. There are various methods, such as incorporating a motor or the like into the cart or the like to transmit power by contacting the road surface or the like, or connecting the power of the engine or motor of an automobile or the like from the tires, engine, motor, etc. of the automobile or the like to the power section of the cart or the like while the automobile or the like is mounted on the cart or the like, or equipping the cart or the like with a device to transmit the rotational force of the wheels of the automobile or the like to the road surface or the like as needed. Also, even if an existing car or the like is not used, for example, if it is a four-wheeled vehicle, two more wheels or so can be attached to the center of the body in advance, and these parts do not come into contact with the ground or the like during normal driving, but by using a structure that allows them to come into contact with the ground by changing the angle using hydraulics or the like, the four wheels can be used to ride up the cart or the like, and the remaining two wheels can be used hydraulically or the like to come into contact with the ground as needed, or giving the cart the function of a hydraulic jack, so that after the automobile or the like has mounted up on the cart, the car can be raised or lowered using hydraulics or the like to change the height of the car's tires or the like to prevent contact with the ground or the like.There are several methods for converting the energy of a car's engine or motor into propulsion energy, such as attaching a device to the side of a car's tires to prevent their rotation from coming into contact with the road surface on a trolley, or attaching a roller-like device to a trolley that rotates in response to the rotation of the tires when the engine rotates on the spot without changing the position of the car passing through inspection, and connecting the roller-like device to wheels with a mechanism that converts the rotational energy of the roller into energy so that the wheels of the trolley do not come into contact with the road surface. To prevent the road surface from freezing, water stored 5 meters underground and heated to about 15 degrees Celsius by geothermal heat is piped to the road surface, and the water is then collected by a motor pump and collected in a tank for circulation. For emergency stops, stakes are installed at the rear of the trolley, and if necessary, they can be lowered onto the road surface to quickly stop the car. Even when using technologies such as linear motor cars to generate lateral energy, cooling a portion of the magnetic field of the linear motor car's track, covering it with ice, and then attaching a sled to it can reduce the vertical levitation force and concentrate most of the electrical energy on lateral energy, making it more efficient. Adjusting the direction of magnetic energy used to generate levitation energy and acceleration energy during linear motor car operation can save as much electrical energy as possible. A sled and the aforementioned powered wheels can also be attached to the linear motor car. Creating a near-vacuum inside the tunnel eliminates wind loss and reduces noise. The magnetic energy transfer section of the linear motor car and the sled can be installed separately. To cool the contact area with the sled, elongated heat-absorbing plates from a freezer can be installed there, or dedicated heat-absorbing devices can be used. Efficient temperature control using a large compressor and underground water at a constant temperature is also possible. The waste heat from the compressor can also be used to power a Stirling engine or other similar device. The compressor can be installed in a space where water drawn from about 5 meters underground is circulated using pipes, etc., to help with heat dissipation.Even for existing roads, to prevent freezing and lower road surface temperatures in summer, water stored in tanks installed 5 meters underground or so beneath roads and walkways can be circulated using pipes to prevent the road surface from freezing or overheating. Circulating water can also be piped around the sleds to improve cooling efficiency in summer. Using plastic bottles or other items, a futon-sized space (the size can be adjusted to be larger or smaller) can be created, keeping the space cool in summer and above freezing in winter. Water from a tank installed 5 meters underground can be piped inside the bottles, and the bottles can be connected to each other to circulate the water and return to the tank. Pumping water using a motor, installing underground tanks on high mountains, or using large underground tanks linked to large-scale facilities such as water purification plants to deliver cool water at a temperature of nearly 15°C even in summer to individual homes allows water to be pumped using only water pressure. Providing parking spaces near train stations and other locations for electric bicycles and other transportation modes makes it easy and convenient to travel to the desired storage location. For example, parking spaces can be equipped with a mechanism for unlocking electric bicycles. A lock can be placed on the wheels of an electric bicycle, and the bicycle can be parked in a parking space. A user who wishes to use the electric bicycle simply launches a pre-registered smartphone app, agrees to the terms of use, and clicks "Start Use." The automatically linked locking device unlocks the bicycle and allows it to be used. A wireless location notification device can be attached to the electric bicycle, allowing the bicycle's administrator to track its location when necessary. The smartphone used by the electric bicycle user and the device that tracks the bicycle's location are wirelessly linked during use, and the device attached to the bicycle can be equipped with an alarm function that notifies the user and administrator by email or other means if the bicycle moves beyond a certain distance. The location of the bicycle can also be automatically recorded and saved using the device. If an incident occurs, such as when the bicycle becomes too far from the user's smartphone, the electric bicycle's motor's current can be stopped to ensure safety. A simpler system could be used to unlock a bicycle or other device in a parking space. The user's identity could be verified via a pre-set password, caller ID, and name over the phone, and the administrator could then remotely activate the unlocking device via the Internet. Alternatively, a password valid for a certain period of time could be communicated to the user via mobile phone, and the user could enter the password within that period by pressing the unlock button on the parking space to unlock it. When locking the parking space, the user's identity could be verified by entering the unlocking password. Other methods include fingerprint or facial or eye authentication using dedicated smartphone software, or the use of a smartphone's videophone function to verify the user's face and speaking style, allowing the administrator to remotely unlock the bicycle. If the parking space locking device and the key for the electric bicycle or other device are separate, the electric bicycle's power could be set to automatically turn off if not used for a certain period of time, in case the bicycle is locked but the key to the bicycle itself is left untouched.A password is set using a computer, using RSA encryption technology or similar, and sent to the locking device. The unlock code is then transmitted via a mobile phone or other means. The locking device is equipped with a unique program that automatically recognizes passwords linked to the time of day, etc. The administrator then communicates the password, which changes randomly with each passing hour, to the user via mobile phone or email. The user is responsible for managing and using the bicycle, from the time of application to the time of use until it is locked and properly returned to the storage location, etc., and this can be determined through regulations or other means. When the locking device is unlocked or locked, it notifies the administrator and user via a signal via a server or other means. The parking space is equipped with cameras with motion detection sensors and light communication devices that record and notify the administrator. For electric bicycles, the key that locks the tire is linked to the electrical system. Users can choose to use multiple locking devices, one for the parking space and one on the bicycle itself, or to install them all on the bicycle. If the locking device is fully installed on the bicycle itself, the administrator can safely unlock and lock the bicycle while checking the status of the parking space using videophone functions, live cameras, etc. For multiple bicycles, unlocking the parking space locking device allows the key and battery of the bicycle to be removed. When locking, mechanical confirmation is provided that the key has been returned to the locking device. Once the administrator confirms via a signal that the electric bicycle's battery is fully charged, the locking device can be locked. When the locking device is locked, the key and battery of the bicycle cannot be removed. This enhances safety. Even if multiple devices are installed 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 provided, and users can authenticate it with a machine installed in the parking space as a means of identity verification, or it can be used in conjunction with the above methods. Tolls can be linked to a card key or smartphone for automatic bank withdrawals. Equipping an electric bicycle with a weatherproof roof allows for comfortable use even in the rain.By connecting plastic bottle-shaped materials, a space can be created for people to pass through, allowing for temperature regulation. Plastic bottles and other materials can be connected and a liquid (such as water) with a constant temperature throughout the year can be stored inside, approximately 5 meters underground (approximately). This liquid can then be pumped inside using an electric pump or other device to provide air conditioning for high and low outside temperatures. Groundwater temperature also fluctuates throughout the year depending on depth, but this can also be utilized to its full potential for air conditioning. If the natural outside temperature is around 5°C and the structure is sufficiently shielded, the internal air temperature will approach this over time if the water is 15°C. Therefore, if the desired temperature is around 22°C, an additional 7°C of energy is required to maintain the air temperature, which is more efficient than raising the temperature from 5°C. The same is true for lowering the temperature. Hot water from hot springs or other sources can be used to further increase the temperature, making air conditioning even more efficient. Specialized materials can also be used for plastic bottle-shaped objects if they meet the intended purpose. The installation location can be selected above ground, underground, semi-underground, or anywhere else depending on the purpose. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles and other materials are connected to allow water to flow through. To achieve this, they are secured with adhesive tape and hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. Plastic bottle-like objects can be made transparent, blocking light but creating an open space. By raising fish inside, they can be used as art. By using similar structures to change the size of the space, it is possible to fill it with hot water or other leisure facilities, creating a space that is integrated with nature. A relaxing hot spring can be created without worrying about rain or wind. The temperature inside the space and the temperature of the liquid, such as the flowing water, can be managed with sensors, automatically adjusting the flow rate of electric pumps, etc., to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to effectively utilize the heat generated by combustion. Water stored in underground tanks can be channeled through structures made of plastic bottles and then returned to the underground tank. Water is moved using electric pumps, etc. Water is reused by circulating it between underground tanks and structures such as plastic bottles.The leisure facilities mentioned above allow for the introduction of fish for viewing and fishing. Plastic bottle-shaped structures can be connected to create a space for people to pass through, allowing for temperature regulation. Plastic bottles and other materials can be connected and a liquid (such as water) with a stable temperature throughout the year can be stored inside, approximately 5 meters underground (approximately). This liquid can then be pumped inside using an electric pump to provide air conditioning for high and low outside temperatures. Groundwater temperature also fluctuates throughout the year depending on depth, but this can also be utilized to its full potential for air conditioning. If the natural outside temperature is around 5°C and the structure is sufficiently shielded, the internal air temperature will approach this temperature over time if the water flowing through is 15°C. Therefore, if the desired temperature is around 22°C, an additional 7°C of energy is required to maintain the air temperature, which is more efficient than raising the temperature from 5°C. The same is true for lowering the temperature. Hot water from a hot spring or other source can be used to further increase the temperature of air conditioning. Specialized materials can also be used for plastic bottles if they meet the intended purpose. The installation location can be selected based on the purpose, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on the temperature. Plastic bottles and other structures are connected to allow water to flow. To achieve this, they are secured with adhesive tape or hollowed out. The structural purpose is to create a temperature-maintaining barrier between the liquid and the outside air. When further liquid is added to the temperature-controlled space created using such plastic bottles and fish are kept there, the structure should be as streamlined as possible to allow the fish to swim in large circles if they swim fast. Setting the width in the direction of movement to 50 cm or so based on the size of the fish ensures safety by preventing head-on collisions. Furthermore, by creating a height difference in such structures, electric pumps can be used to move the liquid from a lower position to a higher position, creating a directional water flow within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be temporarily stopped if necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing underground heat, etc., and an efficient space is created within the structure according to the size of the plants to be grown. The plants are then placed and grown inside the structure, and the structure is transported to a work area where they are cared for, with limited and controlled air circulation between the outside world and the plant. This prevents cross-pollination and complies with the Seed and Seedlings Act. A space isolated from the outside world is constructed using plastic bottles, etc., and this is connected to the space where the plants are grown with a hatch. After people enter and confirm that the space is clean, the connecting hatch is opened and the plants in the internal space can be cared for directly by a person or mechanically using a remote camera or a magic hand. Plants transported to the work area using rails or other means can be remotely monitored by a camera, and tasks such as thinning the plants can be performed automatically using installed machines through AI learning. When circulating liquids in a space constructed using materials such as PET bottles, the temperature of the liquid in an underground tank can be used to heat or cool the space. To further cool or heat the interior of the space, the circulating liquid can be artificially heated (using equipment such as an oil boiler) or cooled (using equipment such as a refrigerator or liquid nitrogen), but objects constructed using PET bottles can also be used as solar heat storage hot water systems, thereby saving on utility costs. By concentrating sunlight around an object constructed using PET bottles, protecting it with airtight materials such as aluminum, and adding insulation, the thermal efficiency can be improved. A structure constructed using materials such as PET bottles can be provided with a suitable internal space where plants can be grown. However, PET bottles circulate liquids such as water inside, and if that water is transported via pipes from an underground tank, it will transfer the underground temperature to the interior of the space. The PET bottles provide a shield between the temperature-transferring material (such as water) and the space. If liquids that utilize underground temperatures are not poured into PET bottles or the like, covering them with heat-retaining or insulating materials can reduce energy costs that would be incurred if the temperature inside the space were to be artificially adjusted with air conditioners or boiler equipment.When creating a space inside an object made from plastic bottles or similar, and the space has several levels, if sunlight cannot reach the lower space due to an object placed inside the upper space, one method is to first concentrate sunlight at an appropriate position and transmit it to the necessary location using optical fiber, or to use a mirror or other device to install a reflector (such as a mirror) in a place where light is likely to hit, on the side of the structure made from plastic bottles or in another location, and refract the light to guide it from the area where light is likely to hit to the area where it is not. Plastic objects such as plastic bottles can be made transparent, so although they block light, an open space can be created, and if fish or other objects are kept inside, it can be used as art. If the size of the space can be changed and made larger using a similar structure, hot water can be placed inside. This allows for the creation of spaces that are integrated with nature, such as by adding other leisure facilities. It also allows for the creation of relaxing hot springs without worrying about rain or wind. The temperature inside the space and the temperature of the running water can be controlled with sensors, and the flow rate of electric pumps can be automatically adjusted to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to effectively utilize the heat generated by combustion. In this way, by minimizing costs, market-competitive agricultural products can be produced and then donated to poor young people free of charge, or a coupon-like certificate can be issued based on terms and conditions that provide certain services in return. Significant reductions in production and service costs can be achieved, and a coupon-like concept can be built based on patents and other rights. Coupons can also be viewed as a conceptual entity. Suppose that Person A owns an agricultural production facility and also owns a restaurant or recreational facility, he or she can manage the usage fees with these coupons and use them to cover daily service fees. He or she can use these coupons to form a community-like group and recruit businesses to participate. Negotiate the use of these coupons with restaurants, recreational facilities, and other businesses operated by other operators. Restaurants and recreational facilities can earn money by serving or selling agricultural produce. Even if recreational facilities have significant labor costs, they can still use this coupon if it includes the provision of such contracted services. We will strive to make this coupon available not only for recreational facilities, but also for service industries and other businesses where payment is typically made in yen or other monetary terms. If Person A is a business owner and receives payment for services in yen as is customary, income will be generated, which could be collected by the government or other organizations and distributed to the poor through welfare (such as welfare assistance). By having Person A and other participants in this system take on this role, people will be able to recognize basic human values, such as the meaning of receiving services, and the government taxes associated with such work can be reduced. We will ensure that food, the basis of human life, is secured so that people can live on it.By having farmers and service providers join this system, which is managed by Person A, farmers and other producers can be relieved of the anxiety that they will only receive a very low relative value in the market, and service providers can feel that the coupon system has social significance that is convincing enough to them. A creates a system of income redistribution and builds a stable society. Furthermore, since these coupons are voluntary, participants are free to choose whether or not to participate. Person A can also choose whether to allow participation if someone wants to participate, and can also decide on the terms of the contract. Person A can decide whether to allow coupons to be redeemed for cash. It is also possible to make them redeemable only through Person A. Whether or not Person A redeems coupons for cash is up to Person A's discretion. It is also possible to decide that coupons with different contents can be exchanged through Person A. Person A also has the right to exchange coupons and freely issue new coupons at their own discretion. Coupons are concepts. Coupons can be paper-based or electronic. By digitizing them and encrypting them using PGP or other encryption methods, and centrally managing the data in a database, Person A can understand the connections between goods, coupons, and services. Person A can freely decide whether to make this data public. Since it is based on a trust relationship, it prevents third-party interference and ensures stability. When coupons are converted into virtual currency, the value of the currency can be determined in advance, such as a certain number of strawberries per coupon. Virtual currency exchanges can also be contractually stipulated so that only Person A can exchange them. To cool, heat, or maintain the temperature inside an object such as a house, water is stored in a tank installed underground and then channeled onto the roof of the house to cool, heat, or maintain the temperature. Ground temperature approximately 5 meters underground is maintained at around 15°C year-round in Honshu, Japan, depending on the latitude. A tank can be prepared there and filled with well water, etc., and then pumped with an electric pump or, if it is from a high point such as a mountain, water can be directed to the roof via pipes using water pressure to allow it to flow appropriately. The channeled water is then collected using gutters and returned to the tank. The tank can also be partitioned to prevent the returning water from mixing with the water inside the tank until it cools to a certain degree.The height of the tank's threshold can be adjusted to control the amount of water that must be pumped into the next tank before overflowing. Multiple tanks can be installed so that returning water is stored in a separate tank for a certain period of time, and when that tank is full, it flows back into the original tank. Partitions may not be necessary if the tank is large or the amount of water flowing is small. The amount of water flowing can also be adjusted by adjusting the output of the pump. Similarly, water flowing onto roads can be used to cool them in the summer and melt snow and prevent freezing in the winter. The amount of water flowing can be programmed in advance using temperature data from weather forecasts, or the output of the pump can be controlled based on the actual temperature. If spring water or well water (such as spring water, where well water has a stable temperature year-round) is used, a tank may not be necessary. Adjusting the amount of water flowing can be achieved by installing a valve or other device to control the diameter of the pipe that leads the water to the roof, or by using a faucet that opens and closes using a computer to control the water flow. While tanks do not necessarily need to be installed underground, using temperature-controlled water using ground temperature allows for temperature control inside homes and other structures with less water, reducing electricity costs for pumps and other equipment. Installing a long, narrow tank at a depth of 5 meters or more underground, with a larger volume at the deeper end and circulating the water with a motor, can help prevent freezing. Installing tanks underground and above ground and connecting them can mix the water in the optimal ratio under optimal temperature conditions. Because temperatures vary depending on the depth underground, installing multiple tanks at different depths and connecting them with pipes can increase efficiency by distributing the mixed water to the roof or other structure. When distributing water to the roof or other structure, calculate the water temperature and heat of vaporization and then distribute the most efficient amount. Pipes can be used to direct water to the highest point on the roof or other structure, allowing it to flow down the roof due to gravity. Pipes can also be used to direct water not only to the roof but also to the sides of the house (for example, pipes can be used to direct water above a window so that it flows along the side of the window). If the roof diameter is 5 meters, the pipes on the roof should also be about 5 meters long, and water will flow over the entire roof. The pipes have holes at appropriate intervals (5 cm intervals, etc., not necessarily 5 cm), and the water comes out from there.In winter, the ground temperature about 5 meters underground is about 15°C. This water can be circulated through pipes installed under the flooring, sides, and ceilings of homes and collected in underground tanks for reuse. Even hotter liquids (hot water) can be used by utilizing hot spring water. To reduce the risk of patent holders being sued over their patents, patent holders must detail the entire process required for the patent, from start to finish, in the claims. If patent holders obtain a patent, they can minimize the risk of being sued for infringement by third parties or having to pay damages if they use the patent in a way that reproduces what is described in the patent. All manufacturing processes, materials, construction methods, and technical steps are described in detail for the patent. All phenomena occurring during the patented procedures, materials, and processes are described in writing in the claims. After a patent is granted, anyone can anonymously file an objection to the patent for six months. However, patent attorneys, etc., are also entitled to file objections based on this right and the confidentiality obligations stipulated in the patent office's regulations. In that sense, they are considered to be related parties with earlier knowledge of the patent than the general public. Since those with access to the patent's documents at the Patent Office also know the patent before it is made public, and their early investigations could potentially give them an advantage, we will convey our opinion to the relevant authorities and ask them to change the rules to stop anonymous objections. We will link plastic bottle-like materials together to create a space for people to pass through, allowing for temperature control when moving through. We will link plastic bottles and other materials together and place a liquid (such as water) about 5 meters underground (a rough guideline) inside, with a temperature that remains constant throughout the year. This liquid will be pumped inside using an electric pump and used for internal air conditioning when the outside temperature is high or low. Groundwater temperature also fluctuates depending on the depth throughout the year, but we will maximize its use for air conditioning. If the natural outside temperature is around 5°C, and if the structure is sufficiently shielded, the air temperature inside will approach that temperature over time if the water flowing through it is 15°C, so if you want to raise the temperature to around 22°C, you can maintain the air temperature with an additional 7°C of energy, which is more efficient than raising it from 5°C. The same can be said for lowering the temperature.Hot water from hot springs or other sources can be used to increase the temperature of air conditioning and other equipment more efficiently. Plastic bottle-shaped objects can also be used with specialized materials if they meet the required requirements. Installation locations can be selected based on the purpose, such as aboveground, underground, or semi-underground. Multiple underground tanks can be installed depending on the temperature. Plastic bottles are connected to allow water to flow. To achieve this, they are secured with adhesive tape or hollowed out. The structural purpose is to create a temperature-maintaining barrier between the liquid and the outside air. When further liquid is added to a temperature-controlled space created using such plastic bottle structures and fish are kept there, the structure should be as streamlined as possible, drawing large circles if the fish swim fast. Setting the width in the direction of movement to 50 cm or so to suit the size of the fish ensures safety by preventing head-on collisions. Furthermore, by creating height differences in such structures, electric pumps can be used to move liquid from lower to higher points, creating a directional water flow within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be temporarily stopped as needed. A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing underground heat, etc., and an efficient space is created within the structure according to the size of the plants to be grown. The plants are then placed and grown inside the structure, and the structure is transported to a work area where they are cared for, with limited and controlled air circulation between the outside world and the plant. This prevents cross-pollination and complies with the Seed and Seedlings Act. A space isolated from the outside world is constructed using plastic bottles, etc., and this is connected to the space where the plants are grown with a hatch. After people enter and confirm that the space is clean, the connecting hatch is opened and the plants in the internal space can be cared for directly by a person or mechanically using a remote camera or a magic hand. Plants transported to the work area using rails or other means can be remotely monitored by a camera, and tasks such as thinning the plants can be performed automatically using installed machines through AI learning.When circulating liquids in a space constructed with materials such as PET bottles, and using the temperature of the liquid in an underground tank to heat or cool the space, the circulating liquid can of course be artificially heated (using equipment such as an oil boiler) or cooled (refrigerator equipment such as liquid nitrogen), but objects constructed with PET bottles can also be used as solar heat storage hot water systems by using the heat of sunlight to heat them, which also saves on utility costs. Heat retention efficiency can be improved by concentrating sunlight around objects constructed with PET bottles, protecting the area with airtight materials such as aluminum, and adding insulation. Leave a moderate amount of space inside structures constructed with materials such as PET bottles. It is possible to create a space in which plants can grow, but if water or other liquids are circulated inside the bottles, the water, when transported via pipes from an underground tank, will transfer underground temperatures to the interior of the space. The bottles provide a shield between the space and temperature mediators such as water. If the bottles are not filled with liquids that utilize underground temperatures, covering them with a heat-retaining or insulating material can reduce energy costs compared to artificially controlling the temperature inside the space with air conditioners or boiler equipment. When creating spaces inside an object constructed from bottles or other materials, if the spaces are multi-tiered and the lower space is blocked by an object placed inside the upper space, sunlight can be concentrated at an appropriate location and then transmitted to the desired location using optical fiber. Alternatively, mirrors can be used on the sides of the bottle structure or elsewhere. Reflectors (mirrors, etc.) can be installed in areas where light is likely to reach the bottles to refract the light and guide it from areas where it is likely to reach the bottles to areas where it is least likely to reach the bottles. Plastic objects such as PET bottles can be made transparent, allowing light to pass through while still blocking it, creating an open space that can be used as art by raising fish and other creatures inside. By using similar structures to change the size of the space and enlarge it, it is possible to add hot water or other leisure facilities inside, creating a space that is integrated with nature. This allows for the creation of relaxing hot springs without worrying about rain or wind. The temperature inside the space and the temperature of the running water can be managed with sensors, and the flow rate of electric pumps can be automatically adjusted to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to heat the water around the space, and the combustion heat and exhaust gases of wood can be effectively utilized to heat the interior. Plants can be grown inside structures constructed using materials such as PET bottles. Since the interior space of the structure does not require human access, plants can be placed on pallets and pulled using wheels or rails, or connected like a train using motor power. The same goes for removing them.The outside of the structure is connected to a tank about 5 meters underground (the depth can be changed depending on the temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using a heater), and water drawn from the tank using a motor pump or similar is poured onto the outside of the structure. If the structure's exterior is constructed so that there are steps or other differences in its structure, liquid water, coolant, etc. can be poured at the highest point of the structure, and liquids of different temperatures can be maintained around it rather than falling all at once to the bottom. In this way, the structure can be cooled or heated. Pipes for conveying water can be installed at appropriate points in the structure, and water can be returned from there to an underground tank. If the structure is constructed using plastic bottles or similar materials, the water inside the bottles, which are connected vertically or horizontally, can be moved as desired by drilling holes in the sides of the bottles when connecting them. Structures constructed from PET bottles can be filled with water and circulated between tanks using a motor pump or other power source. However, instead of doing this, they can be filled with antifreeze (clear is usually better, but colored materials are acceptable in some cases) suitable for insulation, or with light-transmitting materials such as water, glass, marbles, or plastic resin (colored materials are sometimes preferable to adjust the amount of sunlight. A light-blocking cover can also be placed on the outside). As mentioned above, water from an underground tank or hot spring water can be poured outside the structure, then collected and returned to regulate the temperature inside the structure. This can sometimes reduce the construction cost and strength of the structure. Structures made from PET bottles are not limited to PET bottles, and specialized materials can of course be used. One use is to separate an interior space constructed from PET bottles from the outside air. By connecting PET bottle-shaped materials, a space can be created through which people can pass, allowing the internal temperature to be adjusted when they move through. Materials such as plastic bottles are connected together, and a liquid (such as water) that does not change temperature throughout the year is placed inside it, about 5 meters underground (this is just a guideline), and this liquid is pumped inside using an electric pump or the like to be used for air conditioning inside when the outside temperature is high or low.Groundwater temperature also fluctuates throughout the year depending on the depth, but this can be fully utilized for air conditioning and other purposes. If the natural outside temperature is around 5°C, and the structure is sufficiently shielded, the internal air temperature will approach that temperature over time if the water flowing through it is 15°C. Therefore, if you want to raise the temperature to around 22°C, you can maintain the air temperature with an additional 7°C of energy, which is more efficient than raising it from 5°C. The same is true for lowering the temperature. Hot water from hot springs or other sources makes raising the temperature even more efficient. Specialized materials such as plastic bottles can be used if they meet the required requirements. Installation locations can be selected based on the purpose, such as above ground, underground, or semi-underground. Multiple underground tanks can be installed depending on the temperature. Plastic bottles and other objects are connected to allow water to flow through. To achieve this, they are secured in place with adhesive tape or hollowed out. The structural purpose is to create a barrier between the outside air and the liquid to maintain temperature. When a temperature-controlled space made of such a structure using plastic bottles is filled with liquid and fish are kept there, the structure is made as streamlined as possible, drawing large circles when the fish swim fast. Setting the width in the direction of movement to 50 cm or so to suit the size of the fish ensures safety by preventing head-on collisions. Furthermore, such structures can be configured with different elevations, allowing liquid to be moved from a lower position to a higher position using an electric pump, creating a directional flow of water within the space where the liquid is in contact with the fish, preventing collisions. The water flow can also be stopped temporarily if necessary. Water or other liquids, utilizing geothermal heat, can be circulated within the space constructed using materials such as plastic bottles. The structure can be designed to provide efficient space depending on the size of the plants to be grown. Plants can be placed inside the structure, and the structures can be moved to a work area where they can be grown and cared for using rails or wheels with limited and controlled air circulation to prevent pollen cross-contamination and comply with the Seed and Seedling Act.A space isolated from the outside world can be constructed using materials such as plastic bottles, and connected to a space where plants are grown with a hatch. After confirming that the space is clean, the connecting hatch can be opened and the plants can be tended to either manually or mechanically using a remote camera or a magic hand. Plants transported to the work area on rails can be remotely monitored using a camera, and tasks such as thinning can be automated using AI learning. Liquids can be circulated through a space constructed using materials such as plastic bottles, and the temperature of the liquid in an underground tank can be used to heat or cool the space. To further cool the interior of the space, the circulating liquid can be artificially heated (using equipment such as an oil boiler) or cooled (using equipment such as liquid nitrogen in refrigerators), but objects constructed using plastic bottles can also be used as solar-powered heat storage hot water systems, reducing utility costs. By concentrating sunlight around an object constructed from PET bottles or other materials, protecting the surrounding area with airtight materials such as aluminum, and adding insulation, the thermal insulation efficiency can be improved. A moderate amount of space can be created inside a structure constructed using materials such as PET bottles, allowing plants to grow there. However, if water or other liquids are circulated inside the bottles, and this water is transported via pipes connected from an underground tank, the underground temperature will be transmitted to the inside of the space. PET bottles or other materials act as a shield, separating water or other temperature mediators from the space. If liquids utilizing underground temperature are not flowing inside the bottles or other materials, covering them with heat-retaining or insulating materials can reduce energy costs compared to artificially adjusting the temperature inside the space with air conditioners or boiler equipment.When creating spaces inside structures made from plastic bottles or similar materials, if the lower spaces are blocked by objects placed inside the upper spaces, methods include first concentrating sunlight at an appropriate location and transmitting it to the necessary areas using optical fiber. Alternatively, mirrors can be used on the sides of the structure or elsewhere, where light is most likely to reach. These devices refract the light and guide it from areas that are more likely to receive it to areas that are less likely to receive it. Plastic objects like plastic bottles can be made transparent, allowing for the creation of open spaces that block light but can also be used as art by raising fish or other creatures inside. By using similar structures to change the size of the space and enlarge it, it is possible to fill it with hot water or other leisure facilities, creating a space that is integrated with nature. This allows for the creation of relaxing hot springs and other facilities without worrying about rain or wind. The temperature inside the space and the temperature of the liquids, such as the water, can be managed with sensors, automatically adjusting the flow rate of electric pumps, etc., to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to heat surrounding water or other materials, effectively utilizing combustion heat and exhaust gases from wood. Plants can be grown in structures constructed using materials such as plastic bottles. Since the interior of the structure does not require human access, plants can be transported there on pallets by pulling them using wheels or rails, or by connecting them like a train using a motor. The same process is used for retrieving them. Pipes can be used to connect the exterior of the structure to a tank approximately 5 meters underground (the depth can be varied based on temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using a heater). Water drawn from the tank using a motor pump or similar can be poured onto the exterior of the structure. By constructing the structure's exterior with steps, liquid water or coolant can be poured at the highest point of the structure, maintaining different temperatures around the structure rather than having it fall all at once. This allows the structure to be cooled or heated. Pipes for conveying water can be installed in appropriate locations within the structure, and water can then be returned to the underground tank.When constructed using PET bottles, holes can be drilled in the sides of the bottles when connecting them vertically or horizontally, allowing for the water inside the bottles to be freely moved. While structures constructed using PET bottles can be filled with water and circulated between tanks using a motor pump or other power source, they can also be filled with antifreeze (clear is usually better, but colored is acceptable in some cases) suitable for insulation, water, glass, marbles, plastic resin, or other light-transmitting materials (colored materials are sometimes preferable to adjust the amount of sunlight; a light-blocking cover can also be placed on the exterior). Water from underground tanks or hot springs can be channeled outside the structure, collected, and returned, as described above, to regulate the temperature inside the structure. This can sometimes reduce the construction cost and strength of the structure. PET bottle structures are not limited to PET bottles; specialized materials can also be used. One use for these structures is to separate the interior space constructed using PET bottles from the outside air. This is useful when creating a multi-purpose space inside a structure made from plastic bottles, etc. When liquid poured from a part moves due to gravity, creating gaps between structures such as plastic bottles or creating a certain level of rise at the edge of a structure constructed with plastic bottles controls the movement of the liquid and increases the efficiency of the liquid's temperature being transmitted to the space constructed inside. Filling a single or multiple tanks underground at high altitude with natural spring water, hot spring water, river water, etc. and then using pipes to draw the water to a plastic bottle structure at a slightly lower elevation via gravity almost eliminates the electricity costs for pumps, making it eco-friendly (theoretically, natural energy alone is also possible). When filling a space constructed with plastic bottles with liquid and allowing fish to swim, streamlining the swimming space of the structure reduces the risk of the fish colliding with obstacles. A large loop can also be created overall, using pumps and fans to generate water pressure and generate water currents within the space. Creating a space with a gently curved structure constructed from a large circle can prevent fish from coming into contact with walls. Keeping the width of the space for fish to swim around 50 cm (this is only a guideline and depends on the size of the fish) can prevent them from colliding with the sides. Spaces for heat control using groundwater and spaces for temperature regulation using this can be created by arranging structures using plastic bottles, etc., inside which temperature-regulating liquids can be placed, and surrounding spaces can be placed plants that utilize the liquid, or spaces that humans can enter. The arrangement can be freely selected. By placing a structure made of plastic bottles, etc., with spaces of various sizes inside it, in an aquarium set to a certain temperature, the temperature of the liquid filled in the aquarium will affect the space in the object made of plastic bottles, thereby regulating the temperature of that space. The space can be sealed, or air can be introduced or removed through a filter. To shield the space, cover it with a transparent, light-transmitting material or strong plastic, or use a structure made of connected PET bottles (or other specialized bottles) to circulate water from an underground tank located about 5 meters underground in a location that maintains a year-round temperature of about 15°C (depending on latitude, etc.). This can be achieved by pumping the water from the tank (e.g., underground in mountainous areas, where the water naturally falls due to gravity). This allows the water temperature to approach 15°C, and by adjusting the flow rate, it is possible to reduce the cost of vehicle air conditioning. When reducing the pressure of the space through which vehicles travel to a near-vacuum state to reduce air resistance, the perimeter of the space through which vehicles travel can be reinforced with pressure-resistant reinforced plastic or glass. When circulating water with a pump, liquids like water do not boil suddenly even when exposed to sunlight, so the pump does not need to be operated frequently, reducing energy costs. If energy is to be obtained from solar panels, they can be installed on the roof or sides of the facility, or in open spaces such as lanes. To cool solar panels, water maintained at a constant temperature in an underground tank like the one described above can be flowed over the panels, or a pipe-like structure made of a light-transmitting material can be installed nearby and water at about 15°C from the underground tank can be flowed through it to control the temperature of the solar panels. Alternatively, the solar panels can be waterproofed and airtight, and attached to a tub or similar object containing shallow water. Water at about 15°C, installed about 5 meters underground, can be flowed through the tub and collected back into the underground tank. As long as the location allows natural groundwater to flow naturally, a free-flowing system can be used to control the panel temperature. For example, a structure can be constructed using plastic bottles, with the drinking spouts cut out and multiple rectangular cubes glued together to fill the space with water from the underground tank. A hollow structure can be created using a material such as plastic bottles that transmits light but blocks water. Then, items such as solar panels whose temperature needs to be controlled can be placed in the hollow space.Similar devices can be installed in homes to increase power generation. Solar panels' power output declines when they become too hot. Water from the underground tank, kept at around 15°C, can also be used to efficiently air-condition the space. Because the ground temperature around the underground tank varies depending on the depth, multiple tanks can be installed at different depths, allowing the water to be mixed. If necessary, a structure made of plastic bottles can be removed and moved. The lightweight material allows for manual operation, but the ceiling can also be pre-installed for opening and closing with a motor. Inside the underground tank, water, which has been cooled to around 15°C by the ground temperature, is installed in a pipe approximately 5 cm long and 5 cm wide (this is only a rough guideline; the scale can be freely adjusted). A structure with a passageway for water can be installed around the pipe, and the water from the underground tank flows through it. A fan or other device is attached to the end of the pipe to blow air. As the air moves through the pipe, heat is exchanged with the surrounding water (thin materials such as plastic bottles conduct heat well), gradually cooling it in the summer. By increasing the length of the pipe to a certain extent, the temperature at the pipe's outlet will approach that of the water from the underground tank. It will be cold in the summer and warm when the air temperature is below 15°C. For example, a structure can be created by connecting plastic bottles. Fans, such as electric fans, consume little power and are therefore energy-efficient. The pipe does not need to be straight; it can be curved to increase the distance. A thinner pipe can be inserted inside the pipe to allow water to circulate there, facilitating heat exchange when exposed to cold. A metal rod with high thermal conductivity can be inserted between the pipe and the passage through which the circulating water flows, increasing the contact area between the water (around 15°C) and the flowing air. Fans can also be installed not only at the pipe inlet but also at the outlet or along the way to increase heat exchange efficiency. This device can be installed indoors or in areas with a constant ground temperature, such as about 5 meters underground. Air is drawn in and out through pipes.Similarly, if air is pumped into a pipe at a depth of approximately 5 meters underground where the ground temperature is around 15°C, in summer, the air drawn in above ground circulates underground and exits the pipe at a temperature close to the ground temperature of 15°C. This is the same regardless of the season, even in winter. Water flows through all four sides of the pipe or through specific sections. In the case of a two-tiered structure, gravity maintains the water level in the lower section without the need for a ceiling, so a ceiling may not be necessary. Direct contact between the air and the water improves heat exchange efficiency. If the ground temperature around most of the pipe is around 15°C, the temperature of the original air will approach 15°C. Compressed air is used to heat hot spring water or artificially heated water in a boiler for air conditioning in homes and facilities. First, hot water is poured into a space made of plastic bottles, etc., and the above method utilizes the underground temperature of approximately 15°C to exchange heat and bring the air temperature closer to 15°C. However, instead of 15°C, hot water can be added to achieve that temperature. To keep the air warm while it is being sent, the bottles are placed inside a connected pipe, enclosed by the pipes, and the air is sent in a compressed state (or just a slight breeze, depending on the situation). The space for sending hot air can be installed underground or above ground, but if the surface is very cold, considering the cost of digging underground, an insulation system can be used, using water from a tank about 5 meters underground at approximately 15°C. Since underground tanks vary in depth depending on the season, multiple tanks can be used and water can be mixed. If necessary, the outside of the device sending the air made from plastic bottles can be covered with insulation (such as insulating material like styrofoam) to increase efficiency. Cold air can also be sent. It is also possible to circulate or temporarily store water by passing it through thin pipes near objects such as solar panels, which are more efficient when their temperature is close to a certain level, and using the ground temperature about 5 meters underground.Furthermore, after leaving the solar panels and other devices in this state, they (and any other equipment to be protected, if necessary) can be placed inside a structure made of materials such as connected plastic bottles, with the outer periphery being free from outside influences and temperature control. Water can be pumped into the structure, utilizing ground temperature from 5 meters underground, to control the temperature inside the structure and prevent the solar panels from overheating. The water can be circulated or kept still within the structure made of connected plastic bottles, and the flow rate can be adjusted by adjusting the pump. The water that passes through the bottles returns to the underground tank, where the temperature is controlled by the ground temperature. Multiple underground tanks can be installed depending on the depth. To control the temperature of the solar panels, the circulating water can be passed through finer pipes, or such pipes can be installed in advance around the solar panels and other devices. Water from the underground tank can be pumped into thin, light-transmitting pipes and placed around the solar panels to control the temperature. The pipes, solar panels, and other electrical equipment should be waterproofed to prevent water from entering the electrical machinery. Instead of using plastic bottles, it's also possible to use thinner, purpose-built materials to allow water to flow through them. For example, a thin, two-centimeter-thick wall of water can be used around the perimeter of solar panels to control their temperature. Water in an underground tank can be raised to a certain height using a pump, and gravity will allow it to flow through pipes around the solar panels and return to the underground tank. A mist of water (or other liquids) can be sprayed on top of the solar panels to lower the temperature, and the water can be collected and recycled using the water from the underground tank. Other structures, such as plastic bottles, can be constructed with multiple layers, such as those for pouring fertilizer into the space and collecting it, or for allowing water and oxygen to seep underground. Covering the top with a similar structure to create an airtight seal prevents fertilizer, pesticides, and other substances from escaping. Reusing fertilizer can also reduce costs. To let in outside air, you can attach a door to the top and open it, or use a fan to let in air, and you can also make a door for people to enter.Such barriers can also prevent fertilizers used in agriculture from spreading beyond the barrier. In the above-mentioned space constructed using plastic bottles, a tunnel-like space just large enough for a person to pass through can be created, and a cart-like structure can be pulled into the space using rails or tires. In hydroponics, the solution can be poured inside the space, or, for plant cultivation, buckets of water sized to accommodate the root growth can be placed on a cart and moved into the space. Plants can be moved using rails or pallets, so by laying rails in a sunny location or rolling them with tires, they can be moved to any desired location. When cultivating plants hydroponically, the part of the plant above the roots can be moved using an upper cart, reducing the amount of pulling force required. Similarly, plastic bottles can be used to create spaces for cars, and the temperature can be controlled using circulating water, allowing cars to park and take breaks inside. Structures made from plastic bottles can also be placed on top of these structures to grow crops. Electric compressors are typically used for industrial air compression. These compressors are powered by hydraulic gears or by windmills, which transmit their rotational energy through gears. The compressed air can then be stored in a tank about 5 meters underground at a constant ground temperature, or it can be blown into water in a tank located 5 meters underground to maintain a temperature close to 15°C. By using natural energy, such as hydraulic power, to power an air compressor and storing it in a tank underground, it can be extracted at will, like a battery, and used to power the gears. When compressing air with a compressor, the air can be cooled in an underground tank and then compressed to adjust humidity, or the air can be stored underground to lower humidity. Tanks containing compressed air can also be placed underground to lower their temperature. Even large tanks can be installed underground, making it easy to find a suitable location. Using the above system, compressed air can be adjusted in temperature and humidity, and then circulated from facilities to homes through underground pipes, resulting in high efficiency.Rather than storing electricity, the energy could be stored as compressed air (which could be in gaseous or dry ice form). A waterwheel-like structure could also be installed next to a river. Since ria coastlines can send tsunamis to high elevations, such structures could be artificially constructed to use the force of ocean waves to bring seawater up to 10 meters or so above the coastline. The water could then be stored and used to power hydroelectric turbines that use gravity to generate electricity, or to power air compressors and other power sources. By utilizing the energy of ocean waves, the potential energy of large amounts of seawater could be used semi-permanently to benefit human life. Using this method, compressed air could be stored in a tank or similar and transported 20 meters underground, or a stationary tank with a diameter of 20 meters could be used. Then, a water tank filled with water could be installed underground. A rotating wheel or other device could be installed inside the tank, and compressed air would be released from below, causing the wheel to rotate using the energy generated when it rises to the surface. The deeper the tank, the more wheels or other devices that can be installed. The resulting buoyancy generates energy to rotate the waterwheel or wheel. This rotational energy can be used to operate a compressor to generate compressed air or to power a generator, making it extremely efficient. Compressed air (gas), dry ice, and Omasa gas (HHO, HSO, etc.) are placed at a deep point under water pressure in a vertical tank filled with liquid water or other liquids. Heat is then applied, either through electricity or a chemical reaction, to ignite the Omasa gas (a mixture of hydrogen and oxygen is also acceptable). The heat causes the dry ice to expand, and the compressed air also generates upward kinetic energy against the water pressure (gravity), which is then used to power the waterwheel or other device. This energy can be recovered to power a generator. To increase the efficiency of waterwheel rotation, the waterwheel's blades can be designed to be movable and open / close. This opens when pushed by the gas, allowing the kinetic energy to be received by the liquid, minimizing the resistance and slowdown in rotation. The blades open and close, but do not close completely, leaving only a small opening. Alternatively, even if the blades are completely closed, a buoyant object can be attached to a portion of the blade, causing the buoyancy to cause the blades to open slightly when oriented in a specific direction. Water and air flow can also be controlled by introducing air or other materials to push the blades open, or by attaching plates to specific parts of the tank to facilitate air collection in the turbine blades. This turbine-shaped blade design, when installed in a tunnel or other location where gases such as air lack the energy to rise and are subject to water pressure, opens when pushed by the water flow and closes when the water pressure weakens. While hydroelectric power plants at large dams sometimes have heads of 100 meters or hundreds of meters of pipe, simply attaching a hydroelectric propeller downstream is insufficient to fully capture the energy of the water flow to drive the generator turbine, resulting in losses. Therefore, a smaller, pipe-like tunnel or tube with a head of around 10 meters could be used to distribute the energy, or a waterwheel or hydroelectric propeller could be installed in the section where there was previously only water flow. This allows for efficient recovery of the potential energy of the water flow.Furthermore, when compressed air or the like is sprayed from deep places where water pressure is high and the force of the air rising to turn a water wheel or the like is used, if the water tank or tank is designed in such a way that compressed gas is sprayed at exactly 1 o'clock when the water wheel or the like is rotating clockwise, the deceleration of the propeller or water wheel due to water pressure can be suppressed. Compressed gas or the like can also be sprayed from the 6 o'clock direction, etc., so the clockwise rotation force is always continuous, and the energy of the compressed air or gas, the force of buoyancy due to differences in density, etc. are converted into rotational energy for the water wheel or the like. When injecting compressed gas into a hollow shaft such as a waterwheel, a catch can be placed at the 1 or 6 o'clock position, causing the hole in the shaft to catch and open a door for the gas to spray out; the door can then close with the force of a spring when it is no longer caught; gas can be passed through the hollow part of the shaft and covered with a metal cap, and when a hole is opened in a specific part of the cap, the gas can be released when the gas outlet on the rotating shaft reaches a specific position; or the compressed gas release can be linked to the position of the waterwheel, controlling a valve so that the compressed gas only comes out when it reaches a specific position. The shaft that transmits the energy of the waterwheel can be extended horizontally to increase its airtightness so that water does not leak from the water tank or tank, and passed through to a part of the tank where there is no water; or the shaft can be rotated upward using a gear inside the tank, and 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 to a gear or other device to serve as a power source. Several waterwheels and the like can be connected and installed vertically. There are various methods that can be considered, such as extending the tanks deep underground or raising them above ground. In order to transmit the upward energy and buoyancy of air and other substances in water to power, it is also possible to use a structure that is connected by a belt or something and supported in some way (such as a plate that can change its angle depending on the resistance that it receives from the buoyancy, like a bicycle chain (although the angle of the plate does not necessarily have to change depending on the resistance, etc., due to installation costs)). Furthermore, the energy obtained by buoyancy in this way can be connected by a shaft and turned into upward moving energy, which can be used to lift water, etc., and pump water.These can be divided into sections of 10 meters or so, and water pressure and other factors can be adjusted by connecting multiple units vertically. Air and other materials can be reused by using pipes or other structures to flow from the lower structure to the upper structure, efficiently utilizing the upward movement energy of the injected air. The energy associated with the upward movement of air and other materials in each structure can be converted into driving energy using shafts or other means. Water and other materials can be pumped up from the point where the air and other materials in this device come into contact with the ground. Similar structures, such as bicycle chains, can be used to transport water and other materials upward along the rotation. By stacking multiple such devices vertically, the upward movement energy of air and other materials (including carbon dioxide and other materials) can be efficiently utilized and converted into energy, and water pressure can also be controlled. Air and other materials can be collected in tanks or other containers for reuse without being released to the outside. Once compressed air and other materials are introduced, covers can be attached to the surfaces that come into contact 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 compressed air and other flow paths, and valves that open and close in response to these sensors can be attached to optimally control the pressure at each point through which the air flows. The valves can be electronically controlled or analog, using springs or other devices that open and close in response to pressure. The devices can be connected horizontally rather than vertically, and can be made compact. Of course, such devices can also be installed on ships and other structures to provide propulsion. To efficiently utilize energy, water can be transported to a high location (e.g., 60 meters above ground) using a pump, elevator, vehicle, or other buoyancy-based method, as described above. Then, pipes can be oriented downward, allowing the water to fall, and the resulting kinetic energy can be used to power a propeller or other generator. Of course, this energy can be used in a variety of ways. If such a device were installed on a ship, it could generate electricity or directly reduce propulsion energy. Even without pipes, a certain amount of water falls at a limited point. This can then be pumped up using the principles of this device. Because kinetic energy increases in proportion to the square of the object's speed, energy can be efficiently obtained.At a height of approximately 60 meters, the kinetic energy is approximately 625 times greater than at a speed of 1 meter per second. Even at 40 liters per second, considerable power can be generated. Vertically falling water efficiently increases energy. The energy of material movement can be efficiently increased and used to power generators (for example, to drive hydroelectric turbines). Baseballs filled with iron are also suitable. When transferring energy from multiple balls to a power-generating turbine, for example, the balls can be arranged to roll along rails so that they fall into pipes at an elevated position, allowing them to fall regularly. The flow can also be controlled with an open / close stopper. By creating a ball-like shape and providing a slight incline, gravity can easily move the balls without power. Multiple pipes for the balls to fall through can be provided, allowing for independent transfer of energy to turbines, for example, that receive the energy. By slightly shifting the positions of the pipes, the energy of the balls can be efficiently transferred to wheels, water wheels, turbines, etc., without the need for a horizontal row of blades. The movement of the balls, controlled by the drop point above, and the rotation of the turbines below are optimized by adjusting the return device that can collect them at the upper level, such as mechanically. In the case of water at the lower level, the water can be collected in a certain location, and then a mechanically moved bucket can be moved upward, causing the water to move upward. Ball-shaped objects can also be moved to a certain location by gravity, or their direction can be controlled by a lane, allowing the balls to move upward in accordance with the movement of the machine, like a batting machine. To maintain their strength, balls can be covered with impact-resistant materials such as rubber or leather. When installing a facility, taking advantage of natural topography, such as mountains and valleys, and utilizing springs, if available, can reduce the cost of building a large-scale facility from scratch. Existing buildings can also be used, or portions of their edges can be modified. When a certain amount of spring water is bubbling up near the summit of a mountain, the water can be drawn to a specific point using pipes while maintaining its altitude. If the amount of water is small, it can be pumped up from below using power or other means and reused.Even if the difference in elevation between the summit of a mountain and the surrounding lowlands is 50 meters, the mountain's inherent elevation can be maintained at around 50 meters, reducing the need for scaffolding. Mountains are often unpopulated, making it easier to install pipes in those areas. Supports for pipes can be constructed using wooden or concrete scaffolding. Hydroelectric power plants, such as dams, collect water that flows down from surrounding mountains and then utilize the elevation difference between the waterway and the lower part to generate energy. However, by utilizing the mountain's topography, high energy production can be achieved while reducing construction costs. By digging down into the lowlands and placing generators underground, noise and other issues can be reduced and the elevation difference can be increased. When water is being forced downward through a pipe for power generation, connecting a pipe capable of delivering compressed air to the upper part of the pipe can speed the downward flow. Alternatively, a structure consisting of multiple thin pipes can be used, with multiple ventilation holes drilled into the inner pipe, allowing compressed air to be delivered from the higher part of the pipe to ensure smooth water flow. If spring water is unavailable, a certain amount of water can be transported or rainwater can be collected and used. Vehicles can also be moved efficiently using structures that slide on cooled ice, as mentioned above. By constructing rails that accelerate using gravitational energy or engines to a certain extent and then move upward, the energy required to move water to higher positions can be obtained through acceleration due to gravity, thereby reducing the energy cost required for propulsion. Of course, such devices could also be installed on ships and other vehicles to provide propulsion. Taking advantage of the natural law that the temperature around 5 meters underground in Japan remains around 15 degrees throughout the year, building a tube-shaped tunnel there would reduce the energy required for cooling. Alternatively, this structure could be grounded above ground and the outer periphery of the tube could be covered with liquid water during cooling. If the outer periphery of the tube is made of transparent plastic or glass, it would be possible to view the scenery from inside the vehicle.Similar tunnels could be filled with water and other materials, allowing ships and other objects to travel inside sealed vessels, creating a vacuum inside the tunnel and increasing energy efficiency during travel (this can be applied to anything that can travel inside a tunnel). A similar structure could be used with cars and other objects, reducing energy costs and other costs, even for objects as large as trains. This would increase the reliability of autonomous driving. Cars and other objects could be connected to a cart or other platform, with the weight of the car mainly supported by the sled, reducing rolling resistance and other factors. Even on existing roads, to prevent freezing and lower road surface temperatures in summer, water stored in tanks installed 5 meters underground beneath roads and walkways could be circulated through pipes to a depth of 10 cm (approximately) below the asphalt of the road, preventing the road surface from freezing or generating excessive heat. Circulating water could also be circulated around the sled using pipes. This can also be used to increase cooling efficiency in the summer. Using plastic bottles or similar, a futon-sized space (the size can be adjusted to be larger or smaller) is created, maintaining a temperature cool in the summer and above freezing in the winter. Water from a tank installed about 5 meters underground is poured into the plastic bottles through pipes, and the bottles are connected so that the water circulates and returns to the tank. To make an emergency stop for a train, a pipe is installed below the train's track and oil (or a gas, such as clay) is poured into it. A hole is then drilled in the top of the pipe, and a stake or similar object is dropped from the train or similar object to hook it. The point where the stake falls can be contacted with a round plate placed as close to the pipe as possible to prevent pressure from escaping, like an air gun, increasing the pressure inside the pipe and slowing the train or similar object. If multiple pipes are installed and there are multiple train posts, you can first hook one post (a rod-shaped object used to attach a vehicle to the outside) and then add the second and third posts, adjusting the braking force on the train. Holes can be drilled in various locations along the pipe to release pressure, and when a certain pressure is reached, a stopper or other device will be removed, preventing the pipe from breaking due to sudden excessive pressure. Similar to cooling solar panels, a series of connected plastic bottles can be placed on a residential roof, allowing water to flow in and accumulate there, allowing temperature control inside the building. Water can be circulated through tanks installed about 5 meters underground, where the ground temperature is around 15°C year-round. Water can also be stopped for periods of time, such as on roofs, during temperature changes. Structures made of plastic bottles (not necessarily plastic bottles) can also be designed to be buried under roof tiles. It is possible to prepare multiple underground tanks and connect them to different depths to finely adjust the temperature, or if natural cold spring water or hot spring water is available, it can be pumped directly. In winter, this can prevent snow from accumulating on the roof. Also, by running water over the structure, the exterior of the structure can be cleaned.This system takes advantage of the fact that temperatures are maintained at around 15°C year-round at around 5 meters underground and the fact that temperatures change depending on the depth underground. On mountain slopes, for example, a depth is determined based on the required ground temperature, such as 5 meters underground or a shallower depth. A tank made of PET bottles or other materials is filled with water and a structure is constructed to control the temperature of the air created using the PET bottles mentioned above. Spaces are provided inside the PET bottles that allow air to pass through, allowing the air to flow through and control the air temperature. This air is then connected to a space for growing plants, also made of PET bottles, installed above ground via pipes made of PET bottles or other materials. Outside air is taken in through a specific intake port and circulated to the underground space and the space for growing plants. It is possible to block outside air and circulate dedicated gases, or purify the air using an air filter or other device in the outside air intake. Multiple underground tanks can be installed, some higher and some lower, relative to the structure used for plant cultivation, taking advantage of differences in mountain elevation. This allows for natural convection, utilizing the temperature difference with the outside air, reducing air circulation costs. Motor-driven fans can be installed as needed to direct air into the plant cultivation space. Plant cultivation spaces can be designed so narrow that it's impossible for a person to stand through, maximizing space utilization. Pallets containing plants can be placed on carts and moved in and out of the cultivation space using tires or rails. Instead of sunlight, LEDs or heat-to-light conversion elements (as announced by Kyoto University and others) can be used, or sunlight can be drawn into the plant space using mirrors or optical fiber. If the heat applied to the conversion elements affects the plants, a pipe-like device can be installed between the conversion elements and water can be circulated through it to cool the cultivation space. Since the plant cultivation space is already constructed using plastic bottles or other materials, circulating water at a constant temperature (e.g., five meters underground) can prevent excessive temperature fluctuations.In systems that utilize underground temperatures, air conditioned by the underground temperature can be circulated from the underground space to the plant cultivation space. Water stored about 5 meters underground can also be circulated, as it is kept at about 15 degrees Celsius. The plant cultivation space can be large enough for humans to enter, and 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 to control the temperature and humidity within, air conditioned by the underground structure, which utilizes the soil temperature, is transported through pipes to the plant cultivation space. It is possible to transport only air at this time, or to transport water along with the air and pour that water into the plastic bottled juice storage area, thereby also controlling the temperature of the plant cultivation space. In some cases, it is possible to circulate only water, or only air. Designing the plant cultivation space so narrow that humans cannot enter, allows for efficient use of space, and multiple plant cultivation spaces can be stacked on top of each other. From the plant cultivation space to the work area where humans can care for the plants, a long, narrow tunnel made of similar materials like plastic bottles can be constructed underground or above ground, with the plants placed on a cart and pulled by an electric tow truck or winch on rails or some other structure. The work area can also be sealed to allow work to be performed isolated from the outside world, preventing the intrusion of bacteria from outside and the cross-pollination of seeds. The size of the plant cultivation space can be adjusted to accommodate humans, and a solar power generation system can be installed in the space to control the temperature of the solar panels and generate electricity efficiently. These inventions will contribute to a society where goods and services can be exchanged through communication. In order to build a rational society, using inventive technology as a basic security, services can be shared between parties, and those who agree to the inventor's operation of the service network can be entrusted to the inventor under contract to ensure the continuity of those services, with the inventor managing the network.As an application of the method of dropping water or other materials vertically to power a generator or other device below, instead of water, a magnet or other material modified to roll could be dropped, and coils could be placed around the path of the falling lane to generate electricity. The lane could then be used to roll the magnet to a certain location using gravitational energy, and then the gears, shafts, etc., driven by compressed air, as mentioned above, could be used to move the magnet back up to the upper position. Once it reaches the upper position, it could roll down the top of the lane using gravitational energy, go downward to the connecting lane, and then fall again. A certain amount of space could be set up above or near the point where the magnet or other material would be stored, and it could be left waiting there, controlled by a stopper that opens and closes electrically, etc., and when it is released, it would begin rolling again using gravity, etc., along the rails. This can also be done with the device shown above, which drops water vertically and transmits the energy to the blades of a generator below to generate electricity. Water can be stored in tanks at the top or bottom and then dropped as needed to generate energy. Natural water or spring water can also be stored there. Various methods, such as a water pump, can be used to power the water. When connecting plastic bottles and supplying temperature-controlled water from an underground tank to control the temperature of a space inside, arranging the bottles in a multi-tiered structure, such as an upward one, increases the space per unit area. This space can be used as a plant cultivation space, or a workshop (for example, if manual work such as thinning is performed below the space) can be connected to the bottom using a spiral rail or other device. Elevators can be used to move plants and the carts carrying them from higher to lower levels. Elevators and other structures also have rails that can be easily changed in direction, and the rails' course and direction can be easily changed, or they can be rearranged freely like a puzzle.Elevators and other devices can reach the edge of the cultivation space, or chairs can be placed on the elevator and stopped at each floor. Rails on the elevator can be connected to rails in the cultivation space, allowing plants to be moved around chairs and other structures using carts. People can also work while seated. This tall, multi-level structure can also be enclosed with light-transmitting vinyl or other materials to seal the interior. A simple, single-level structure can easily be sealed by surrounding it with a vinyl or other structure, and multiple airlocked doors can be installed at the entrance to isolate it from the outside world. The interior of a structure made from plastic bottles or other materials can be sealed by sealing it to prevent outside air from entering. Elevators and other devices can also be installed inside the space of an enclosed structure. Since the plants and other structures inside are isolated from the outside world, seeds do not mix and insects do not come. When creating a space inside a structure made of connected plastic bottles and other materials to grow plants, the structure can be surrounded by light-transmitting plastic to block out the outside world. When a person approaches the structure to work, parts of the structure, such as plastic bottles, can be moved to allow access to the interior of the space. After work is complete, the structure (parts, etc.) made from the processed plastic bottles can be returned to its original position. If the interior of a structure made of plastic bottles is isolated from the outside atmosphere and used to grow plants, carts for moving the plants can be placed inside. These carts can be connected like a train with chains and tires or rails to power winches or some of the carts can be motorized. To efficiently capture sunlight into the space, methods such as transmitting sunlight using sunlight collectors (such as Himawari) or optical fiber can be used, or the light can be linked to the desired space using movable mirrors that can be adjusted to any angle, or a combination of these methods can be used. There is a device called R, which is shown in the drawing as a concept that includes at least the functions "1" to "7" below, as well as other functions in part, in whole, or in part. "1" Water (liquid, etc.), liquid metal, liquid mercury, etc. can also be used."2" The upward energy generated inside the tank is generated by using the difference in gravity between the air (gas, etc.). This device converts the upward energy generated inside the tank into rotational energy by connecting a device with a spring or other element that can be opened and closed, essentially a bicycle chain-like device and a crank-like device. "3" This rotational energy transmission device is installed inside the tank (supported by a support or other element to prevent it from wobbling). "4" Water or other liquids are introduced into the tank from the outside using pipes or hoses. "5" Compressed air (gas, etc.) is introduced into the tank, and while the pressure is controlled by a sensor, it is ejected through pipes so that it hits the blades of the rotational energy transmission device. 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 or other elements. This energy can be used to power a generator (to turn gears, etc.) or other energy sources. The energy of this water or other liquids can also be used to power devices that compress air, etc. This energy can also be used to power electrolysis devices to produce hydrogen, etc. "7" Water that went down. Liquids, etc., are stored in a tank or similar device and then transported upwards using rotational energy, which converts the difference in gravity between the liquid and gas into rotational energy. Liquid metal, mercury, etc., can also be used as the liquid to be dropped, such as water. The entire device can be sealed with strong walls or other materials to create a vacuum, eliminating air resistance. To efficiently generate compressed gas, a cylindrical tube and a device acting as an efficient stopper are used, moving from top to bottom within the tube and compressing the air without leaking. This linear device is surrounded by a rubber-like, life-ring-like section that seals tightly to the cylinder using air pressure. The air pressure inflates the life-ring section, preventing air leakage. To improve slippage, a nozzle extending from the inside of the stopper can be used to spray lubricating oil around the area where the life-ring-like rubber seals. A tank or other device can be placed above the stopper-acting device, and a heavy object, such as water, can be placed there and moved downward by its weight. A hoisting wire or winch can also be installed to move the stopper-acting device upward. A chain can also be connected downward, and in a situation where gas cannot enter or exit through water or other fluids, it can be connected to an external gear or the like, and water or other liquids can be dropped into it from above through a pipe or the like, which uses the energy to turn the gear and pull the device that acts as a stopper downward. To move this stopper or other device upward, the air can be released from inside a rubber float or the like, causing it to deflate and break contact with the cylindrical tube, allowing it to be smoothly pulled up, or the water or other weight can be drained by opening a tank door or valve below and moved to another tank or the like through a pipe or the like. The water can be reused by converting the difference in gravity between the liquid and gas into rotational energy and bringing it upward, or by returning it to an upper tank or the like. To eliminate air resistance, the pipe through which the liquid, water, liquid metal, etc. falls can also be depressurized or created into a vacuum. For this reason, if there is a device that uses the power of the flow inside a pipe through which a liquid or the like passes to power a turbine or the like of a power generation device to generate electricity, the device itself can be covered with a strong material, such as steel, so that it is maintained in a vacuum or reduced pressure state, and the movement of the liquid or the device itself, for example the generator device, can also be maintained in a vacuum or reduced pressure state.A structure isolated from the outside, like a submarine, is created, and piping and power generation equipment are installed inside it, followed by a single ventilated pipe. Air is then sucked out through this pipe using a compressor, creating a vacuum or reduced pressure in the area where people and internal equipment reside. Of course, a refrigerant (such as the chlorofluorocarbons used in air conditioners or their substitutes, such as HFCs) can be used for the gas (the principle is to use the difference in gravity between gas and liquid to generate rotational force for blades installed inside a tank, using a bicycle chain-like mechanism). For example, the refrigerant can be compressed and then piped directly to the blades, which convert the energy into rotational energy, or the compressed refrigerant can be passed through a pipe into a tank filled with water or other liquid, where the heat is exchanged with water (any shape as long as it can transfer heat) using the principle of a heat pump, or with air guided from the outside through a separate pipe. The pressure of the compressed refrigerant, which has released a certain amount of thermal energy, is then released, controlled by a control valve, below the blades, etc., to convert it into rotational energy, obtaining rotational energy. As a preliminary process, the refrigerant's heat of vaporization can be used, as in a cooler, by piping outside air near the refrigerant-filled pipes, for example. When the refrigerant's compression rate decreases, heat exchange with the surrounding air occurs, lowering the temperature of the surrounding objects. If the tank containing the rotational energy conversion device contains water (liquid, etc.), its temperature will decrease due to the action of the refrigerant. Therefore, if the device is installed at a depth of about 5 meters underground in mid-latitudes where the annual ground temperature is stable at around 15°C, the water (liquid, etc., of any shape or form that does not react easily with refrigerants, etc.) that has lost heat due to the heat from the ground can be balanced by the addition of geothermal heat from the surrounding area.When the temperature inside the device extracting rotational energy drops significantly due to heat exchange with the refrigerant, for example, a tank can be installed 5 meters underground at a point maintained at about 15 degrees Celsius year-round, and water (liquid, any shape or form as long as it does not react easily with the refrigerant) can be placed inside, and the temperature of the water inside can be controlled using geothermal energy (ground temperature fluctuates with depth, but underground, it is inversely proportional to changes in outside air temperature, so the depth at which the tank is installed can be freely changed to ensure a stable intake of thermal energy). A pipe can then be installed inside the tank to connect the cooled water to another tank installed underground, or the replaced water can be placed in a tank installed about 5 meters underground and maintained warm by geothermal energy. Pipes can be installed inside the tank containing the cooled water to introduce warm outside air to raise the temperature of the water inside the tank, or the cooled outside air can be piped to a space above ground using a pressurized fan for use in air conditioning. If water, etc., whose temperature is maintained by the above-mentioned ground temperature, is circulated around a tank or other device containing a rotational energy extracting device using pipes or other means, the heat replenishes the heat lost by the refrigerant. The refrigerant (gas, etc.) that reaches the top of the tank or other location passes through pipes, with the pressure regulated by control valves and pressure sensors, and moves sequentially through pipes to the next device equipped with a device that converts the refrigerant into rotational energy. The refrigerant then returns to the first compressor through pipes and is recycled. Using the same principle as a solar water heater, which collects solar energy using a concentrator and converts it into thermal energy such as water, water (liquid, etc.) heated to the highest possible temperature can be introduced through pipes into a tank or other device containing a rotational energy extracting device, and a refrigerant (carbon dioxide, etc.) whose temperature has been increased by compression can be introduced there. This boils the water (liquid, etc.) in the tank, and the resulting power can be used to power the impellers of the rotational energy extracting device. Heat can also be obtained from sources such as solar energy (such as sunlight), heat from magma, and geothermal heat from naturally occurring hot springs.Similar to a solar water heater, which uses solar heat to heat bathwater, water can be heated to a high temperature, or a substance with a high boiling point, such as sodium, and used to power a device (such as the circled R in Figure 8) that converts the heat into rotational energy. When guiding thermal energy to a device like the circled R using this mechanism, the sodium can first be heated to a high temperature and the energy transferred to water passing through a pipe, or sodium (a substance with a high boiling point) can be moved directly through a pipe. High-temperature sodium (a substance with a high boiling point) can be guided (moved) through a pipe into a space containing water (a liquid) in a tank of a device like the circled R, causing the surrounding water (a liquid) to boil. Heat-transferring substances like sodium can be collected in a tank through a pipe and reused. This can be done using a pump powered by a motor. The vaporized water (a liquid) can also be transported through a pipe to a tank and then returned to the tank inside the device like the circled R. Placing a tank somewhere underground, such as 5 meters, where the temperature can be maintained at around 15 to 17 degrees Celsius year-round, can make it easier to control the temperature. The refrigerant can also be used as energy for a device like the one shown in Figure R surrounded by a circle. The high-temperature refrigerant can be passed through pipes to a device like the one shown in Figure R, using pressure sensors and valves to guide or recover the gas. Alternatively, the high temperature of the refrigerant can be used to heat and boil the water in a device like the one shown in Figure R, which can then be converted into rotational energy. By utilizing the relationship between heat and the state of matter in the three states of matter, a pathway can be created in a material that can be transformed using natural energy, which can then be used to power a device like the one shown in Figure R, which converts the energy into rotational energy, or to cool or heat other things (such as a cooler or heater), or to heat water using a heat pump.A device like the circled R generates rotational (driving) energy and uses it to pump water or other liquids from below to above (rotational energy can be used to move a belt or other device, which then pumps or moves materials by placing water or other liquids in an attached bucket). Water or other liquids can also be moved in the opposite direction of gravity, from below to above. When water or other liquids are dropped, gravity causes the kinetic energy to rise, which can be used as a source of energy for hydroelectric generators or for various other purposes. When an air conditioner is operating as a heater, heat exchange by the refrigerant becomes difficult in cold outdoor temperatures, such as midwinter. Therefore, liquids (water, etc.) stored in tanks installed underground, typically 5 meters underground and maintained at a constant temperature of 15 to 17 degrees Celsius year-round, can be circulated through pipes around the air conditioner's outdoor unit or heat exchanger. This allows the refrigerant to exchange heat at a temperature higher than the cold outdoor air in winter. Pipes for water can be installed around the pipes carrying the refrigerant, and the water can be collected and reused in tanks installed 5 meters underground (several tanks can be connected with pipes, allowing the temperature inside to be adjusted. Tanks can also be installed at different depths). Water can be moved using natural elevation changes or pumps. It is said that a battery level of 20-80% is optimal for smartphones and other devices, so a control device with a function that can automatically set the timing for charging can be used within this range. This device can be linked to a smartphone or other device via Bluetooth (registered trademark) or a USB cable, and data such as remaining battery power can be read from a control program on the smartphone, allowing the start and stop of the device, linked to the freely adjustable remaining battery power, to be controlled automatically. Electric assist bicycle batteries may not be able to generate enough power in the cold winter weather, so a heat generating device such as an electric heater is attached around the battery and the heater's heat source is turned on and off according to the temperature of the battery.The circuit is set up so that the power of this device is cut off when the battery of the assisted bicycle is low. When cows or other animals are kept in a space inside a storage facility made from materials such as plastic bottles, as shown in Figure 1, methane gas emitted from the cows' burps can be separated and collected. If the cows or other animals are in the lower part of the space, the space can be made into a multi-stage structure, with pipes connecting the spaces and separating and collecting methane gas accumulated in the upper spaces. The inside of the space is sealed, so it does not naturally mix with the outside air. In a space like ▲R▼, which can let in outside air through a pipe with a circulation valve or air filter, compressed air (gas, etc.) or refrigerant (such as chlorofluorocarbon or something with similar properties) can be passed through a pipe into a tank or something containing water or other liquid (even if there is no liquid inside, if a high-pressure gas or something similar is blown in a certain direction, the force can be converted into rotational energy, like the blades of ▲R▼. When converting the heat energy into rotational energy, for example, by using the same principle as a cooler or heater, where a refrigerant (such as chlorofluorocarbon or a similar substance) can heat up or cool down due to pressure changes, or conversely, its volume can suddenly increase and it can become cold, depending on its properties. Such devices can generate electricity while providing a heat source, or they can be used to cool the surroundings. A substance that is difficult to vaporize, such as sodium, can be sent through a pipe to the inside of a ▲R▼ to boil water in a tank, which can then be converted into rotational energy. To lower the velocity of a downward-moving chain with rotating blades, for example, by passing cold water (approximately 15°C) through a pipe around the chain and passing it through a tank, the temperature around that part can be reduced, allowing the chain to move smoothly. Of course, it's also possible to store water in a tank about 5 meters underground where the temperature remains at about 15°C year-round, and then pipe it into a device like ▲R▼ without it mixing with the water in the tank. If a tank like ▲R▼ is filled with water and air is pumped into it, a filter with a function that can separate materials that pass through based on the properties and characteristics of the material can be installed at the point where the air and water meet, allowing the air to pass through the pipe to the water more stably. For example, a filter placed between pipes can allow materials to move from left to right but prevent materials on the right from moving left, or a filter with a function that allows air to pass through but not water, depending on the properties and fineness of the material that can pass through the filter, can also be used. For example, filters can be attached to the ▲F▼ location (Diagram 8). ▲F▼ can be placed wherever necessary on pipes, etc. The letters surrounded by ▲ and ▼ in ▲F▼ mean that they are surrounded by a circle. In this case, it means an F surrounded by a circle. The same goes for others.Heat can also be obtained from sources such as solar energy (e.g., sunlight), the heat of magma, and geothermal heat from naturally occurring hot springs. This can be used to power a device (such as ▲R▼ in Figure 8) that converts water into rotational energy, or it can be used to power a device similar to a solar hot water heater that uses the heat of the sun to heat bathwater. When guiding thermal energy into a device like ▲R▼ using this system, sodium or other substances can first be heated to a high temperature and the energy transferred to water passing through pipes, or sodium can be placed in the pipes and allowed to flow. When high-temperature sodium or other substances are guided through pipes into a space containing water or other liquids in a tank like ▲R▼, the heat will boil the water. Heat-transmitting materials like sodium can be passed through pipes and collected in a tank or other container for reuse. This can be done using a motor-driven pump. Vaporized water can also be transported through pipes to a tank or other container and then returned to the tank of a device like ▲R▼ using pipes. It may be easier to control the temperature of a tank by placing it 5 meters underground, where it remains constant at around 15 to 17 degrees Celsius year-round. The refrigerant can also be used as energy for a device like ▲R▼. High-pressure refrigerant can be passed through pipes to a device like ▲R▼ containing water or other liquids, using pressure sensors and adjusting valves to guide or recover the gas. Alternatively, the high temperature of the refrigerant can be used to heat and boil the water in a device like ▲R▼, which can then be converted into rotational energy. By using the relationship between the three states of matter and heat, pathways can be created that allow a substance to change state using natural energy, and this can be used to operate a device like ▲R▼ that converts the state into rotational energy, or to cool other things (such as a cooler) or heat other things (such as a heater), or to boil water using a heat pump.A device like ▲R▼ can generate rotational energy and use it to pump water from below to above (for example, by using rotational energy to move a belt or similar device and pouring water into an attached bucket). It can also move water from below to above, counter to gravity. When water is dropped downwards, the kinetic energy rises due to gravity, and this energy can be used as a source of energy for a hydroelectric generator or for various other purposes. When an air conditioner is operating as a heater, the refrigerant is less able to exchange heat in cold winter weather. Therefore, water stored in tanks located underground, typically 5 meters below ground and kept at a constant temperature of 15-17°C year-round, can be transported through pipes around the air conditioner's outdoor unit or heat exchanger. This allows the refrigerant to exchange heat at a temperature higher than the outside air in winter. Pipes for water can be installed around the pipes through which the refrigerant flows, and the water can be collected and reused in tanks installed 5 meters underground (several tanks can be connected with pipes, and the temperature inside the tanks can be adjusted. Tanks can also be installed at different depths). Water can be moved using natural elevation changes or pumps. It is said that a battery level of 20-80% is good for the battery life of smartphones and other devices, so a control device with a function that can automatically set the timing for charging at this level is used. This control device is linked to a smartphone or other device via Bluetooth or USB cable, and data such as remaining battery capacity is read from a control program on the smartphone, etc., and the start and stop of the control device, which is linked to the freely set remaining battery capacity, can be controlled automatically. Electrically assisted bicycle batteries can sometimes not produce enough power in the cold winter weather, so a device such as a heat-generating electric heater is attached around the battery and the heater's switch is turned on and off according to the battery's temperature. The circuit is set up so that when the battery of the assisted bicycle is low on power, the power of this device is cut off.When cows are kept in a space inside a building constructed from materials such as plastic bottles, as shown in Figure 1, methane gas emitted from cow burps can be separated and collected. If the cows are in the lower part of the space, the space can be made into a multi-tiered structure with pipes connecting the spaces, and methane gas accumulated in the upper spaces can be separated and collected using a device. The inside of the space is sealed, so it does not naturally mix with outside air. Outside air can be introduced through a ventilation valve or pipes with air filters. The symbol ▲R▼ means an R surrounded by a circle, as used in Japanese patents. As explained in Figures 10 and 11, a rotating ring-like shape is created using parts such as bicycle cranks and gears and the function of a chain or other device that transmits rotation (a belt or other device with equivalent functionality would also be acceptable). The chain and bucket are connected, so that when the chain moves, the bucket also moves. Suppose the difference in elevation between the high and low parts of such a structure is about 60 meters. When a bucket approaches the high point, it is tilted by touching the bucket slightly, causing the water, mercury, or other fluid substance inside it to fall out and be stored in a tank or other container. The device's crank or gear can then be rotated using an electric motor, waterwheel, or other power source to apply rotational force. A tank for storing water, mercury, or other fluids (liquids with high fluidity) can be installed at the bottom of the device, and the buckets can be filled with water or mercury as they pass through it. Alternatively, a pipe can be used to transport water, mercury, or other fluids (anything with a high specific gravity) somewhere along the rotating path, and the water, mercury, or other fluids can be replenished in the same way as water from a faucet is poured into the bucket. The structure can also allow water, liquid mercury, or other fluids to fall downward from the tank or container at the top using a pipe, allowing them to be collected in a bucket or container. The bucket or other object has downward kinetic energy, which is given by gravity depending on the distance it falls. The distance it falls from the tank above can be changed by changing the distance to the bucket or other object that catches it.Assuming this rotation speed is approximately 2.2 meters per second, there are 60 buckets attached at roughly equal intervals, and the chain is approximately 132 meters long, then the buckets will deposit water, liquid mercury, etc. into the upper tank every second. Assuming that water, liquid mercury, etc. is added to the buckets from the lower tank or a supply device so that the buckets hold approximately 40 liters, 40 liters of water, liquid mercury, etc. will move to the upper tank every second. If 10 liters of water is dropped from the upper tank into the buckets every second and the buckets receive it, assuming the distance from the upper tank to the buckets is 15 meters, then the kinetic energy is calculated to be 2,250 joules. This roughly translates to a downward force acting on the chain. Even if the power of the drive motor that initially rotated this device is reduced, the downward kinetic energy of the water, liquid mercury, etc. is transmitted to the chain, allowing the rotating device to continue operating even as the power of the drive motor is gradually reduced. Since kinetic energy is 1 / 2 x mass x velocity squared, a tenfold increase in velocity results in a 100-fold increase in kinetic energy. The amount of water or liquid mercury dropping from the upper tank to the bucket below can be adjusted using a valve, and the circumference of the device itself can be freely adjusted, allowing for optimal performance by adjusting the various parameters. Resistance that impedes rotation, such as transferring water or liquid mercury from the lower tank to the bucket, can be minimized to maximize efficiency. The water or liquid mercury in the upper tank can then be dropped down a distance of 60 meters using a pipe, and the resulting energy can be transferred to a water wheel or other device to power a generator. The device can also be enclosed in a shield and the air removed using a suction device, creating a vacuum or low-pressure environment inside, eliminating or reducing air resistance as the water or liquid mercury falls. Such a device will serve to transfer gravitational energy to rotational energy via water, liquid mercury, etc. Of course, the upper tank can also be used to move water, liquid mercury, etc. using the energy of a water pump or a water wheel that rotates by receiving the flow of a river, as in the past.To control the time and drop water or liquid mercury (or even iron balls) from the upper tank at regular intervals, a shishiodoshi (a type of bamboo found in Japanese gardens that can be made stronger out of metal) can be installed between the valve c1 and the upper tank, and the shishiodoshi will tilt when 10 liters have accumulated, or a device can be installed by modifying a water wheel so that it will perform a certain action when a certain weight is reached. By applying a certain load to the water wheel, the rotation speed can be controlled. It is possible to construct a device that operates more efficiently than a conventional power device. The device shown in Figures 11 and 12 is an application of the device that appears in Figures 4 and 6. The force acting on materials with different masses per volume. This difference can be used as a power source to drive gears, etc., and the energy can be converted into rotational energy or other energy sources for other purposes. Even if such a device were placed in a zero-gravity environment (e.g., in space), the rotation of the base would cause the fixed tank containing liquid, dry ice, or gas to rotate, thereby giving the liquid mass a fixed direction. In principle, this device can generate rotational energy and other energy in the same way as under gravity. Temperature changes inside and outside the tank can also be controlled by surrounding the tank with a liquid or other substance to maintain or regulate its temperature. Magnets and coils can be placed around the rotating base, utilizing the power generation principles of motors, to generate electricity. By introducing a liquid (such as water, mercury, a gas delivered through a pipe, or a substance with a lighter specific gravity than dry ice and more fluidity) into the tank and a solid substance (such as dry ice or a substance with a volatile chamber) or gas that vaporizes due to a pressure difference, for example, dry ice will vaporize into carbon dioxide, which moves in a fixed direction within the liquid, and this energy can be utilized. Multiple tanks can be connected, and at certain points, carbon dioxide (gas) or other substances can be repressurized and turned into dry ice or liquid. This can then be re-flowed (moved) into the tank using pipes or other devices. If necessary, external pressure can be applied to force the substance into the tank. If a solid substance is being forced into the tank, the tank can be connected to a certain space that can be sealed off from the outside, and the force can be used to physically force the substance in. Even in the case of a liquid, the liquid can be placed in a certain space, sealed off from the outside, and then pushed in using a pressure pump or other device. For example, if water is used as the liquid in a tank and dry ice is added, the dry ice will turn into carbon dioxide gas within the tank, and this gas can then be passed through several tanks. It can then be collected using pipes or other devices, and re-pressurized, either in a single tank or to turn into dry ice or liquid. It can then be placed back into the inlet of the first tank. The process then repeats.As shown in Figure 4, by arranging wood and other materials tightly in a shape similar to the three great pyramids of Egypt, or by freely leaving spaces between them, it is possible to create spaces useful for daily life in valleys in mountainous areas. This creates a large flat area above, creating a vast, usable space. Storing wood that has absorbed carbon dioxide also helps combat global warming. Please note that these diagrams of invention examples are merely examples, and can be freely combined according to the size and purpose. Providing parking spaces near train stations and other locations for electric bicycles and other transportation modes makes it easy and convenient to travel to the desired storage location. For example, parking spaces can be equipped with a mechanism for unlocking electric bicycles. A lock can be placed on the wheels of an electric bicycle, and the bicycle can be parked in a parking space. A user who wishes to use the electric bicycle simply launches a pre-registered smartphone app, agrees to the terms of use, and clicks "Start Use." The automatically linked locking device unlocks the bicycle and allows it to be used. A wireless location notification device can be attached to the electric bicycle, allowing the bicycle's administrator to track its location when necessary. The smartphone used by the electric bicycle user and the device that tracks the bicycle's location are wirelessly linked during use, and the device attached to the bicycle can be equipped with an alarm function that notifies the user and administrator by email or other means if the bicycle moves beyond a certain distance. The location of the bicycle can also be automatically recorded and saved using the device. If an incident occurs, such as when the bicycle becomes too far from the user's smartphone, the electric bicycle's motor's current can be stopped to ensure safety. A simpler system could be used to unlock a bicycle or other device in a parking space. The user's identity could be verified via a pre-set password, caller ID, and name over the phone, and the administrator could then remotely activate the unlocking device via the Internet. Alternatively, a password valid for a certain period of time could be communicated to the user via mobile phone, and the user could enter the password within that period by pressing the unlock button on the parking space to unlock it. When locking the parking space, the user's identity could be verified by entering the unlocking password. Other methods include fingerprint or facial or eye authentication using dedicated smartphone software, or the use of a smartphone's videophone function to verify the user's face and speaking style, allowing the administrator to remotely unlock the bicycle. If the parking space locking device and the key for the electric bicycle or other device are separate, the electric bicycle's power could be set to automatically turn off if not used for a certain period of time, in case the bicycle is locked but the key to the bicycle itself is left untouched.A password is set using a computer, using RSA encryption technology or similar, and sent to the locking device. The unlock code is then transmitted via a mobile phone or other means. The locking device is equipped with a unique program that automatically recognizes passwords linked to the time of day, etc. The administrator then communicates the password, which changes randomly with each passing hour, to the user via mobile phone or email. The user is responsible for managing and using the bicycle, from the time of application to the time of use until it is locked and properly returned to the storage location, etc., and this can be determined through regulations or other means. When the locking device is unlocked or locked, it notifies the administrator and user via a signal via a server or other means. The parking space is equipped with cameras with motion detection sensors and light communication devices that record and notify the administrator. For electric bicycles, the key that locks the tire is linked to the electrical system. Users can choose to use multiple locking devices, one for the parking space and one on the bicycle itself, or to install them all on the bicycle. If the locking device is fully installed on the bicycle itself, the administrator can safely unlock and lock the bicycle while checking the status of the parking space using videophone functions, live cameras, etc. For multiple bicycles, unlocking the parking space locking device allows the key and battery of the bicycle to be removed. When locking, mechanical confirmation is provided that the key has been returned to the locking device. Once the administrator confirms via a signal that the electric bicycle's battery is fully charged, the locking device can be locked. When the locking device is locked, the key and battery of the bicycle cannot be removed. This enhances safety. Even if multiple devices are installed 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 provided, and users can authenticate it with a machine installed in the parking space as a means of identity verification, or it can be used in conjunction with the above methods. Tolls can be linked to a card key or smartphone for automatic bank withdrawals. Equipping an electric bicycle with a weatherproof roof allows for comfortable use even in the rain. By connecting plastic bottle-shaped materials, a space can be created for people to pass through, allowing for temperature regulation. Plastic bottles and other materials can be connected and a liquid (such as water) with a constant temperature throughout the year can be stored inside, approximately 5 meters underground (approximately). This liquid can then be pumped inside using an electric pump or other device to provide air conditioning for high and low outside temperatures. Groundwater temperature also fluctuates throughout the year depending on depth, but this can also be utilized to its full potential for air conditioning. If the natural outside temperature is around 5°C and the structure is sufficiently shielded, the internal air temperature will approach this over time if the water is 15°C. Therefore, if the desired temperature is around 22°C, an additional 7°C of energy is required to maintain the air temperature, which is more efficient than raising the temperature from 5°C. The same is true for lowering the temperature. Hot water from hot springs or other sources can be used to further increase the temperature, making air conditioning even more efficient. Specialized materials can also be used for plastic bottle-shaped objects if they meet the intended purpose. The installation location can be selected above ground, underground, semi-underground, or anywhere else depending on the purpose. Multiple underground tanks can be installed depending on temperature and other factors. Plastic bottles and other materials are connected to allow water to flow through. To achieve this, they are secured with adhesive tape and hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. Plastic bottle-like objects can be made transparent, blocking light but creating an open space. By raising fish inside, they can be used as art. By using similar structures to change the size of the space, it is possible to fill it with hot water or other leisure facilities, creating a space that is integrated with nature. A relaxing hot spring can be created without worrying about rain or wind. The temperature inside the space and the temperature of the liquid, such as the flowing water, can be managed with sensors, automatically adjusting the flow rate of electric pumps, etc., to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to effectively utilize the heat generated by combustion. Water stored in underground tanks can be channeled through structures made of plastic bottles and then returned to the underground tank. Water is moved using electric pumps, etc. Water is reused by circulating it between underground tanks and structures such as plastic bottles.The above leisure facilities have fish available for viewing and fishing. By connecting plastic bottle-shaped materials, a space can be created for people to pass through, allowing for temperature regulation. Plastic bottles and other materials can be connected and a liquid (such as water) with a constant temperature throughout the year can be stored inside, approximately 5 meters underground (approximately). This liquid can then be pumped inside using an electric pump or other device to provide air conditioning for high and low outside temperatures. Groundwater temperature also fluctuates throughout the year depending on depth, but this can also be utilized to its full potential for air conditioning. If the natural outside temperature is around 5°C and the structure is sufficiently shielded, the internal air temperature will approach this over time if the water is 15°C. Therefore, if the desired temperature is around 22°C, an additional 7°C of energy is required to maintain the air temperature, which is more efficient than raising the temperature from 5°C. The same is true for lowering the temperature. Hot water from hot springs or other sources can be used to further increase the temperature, making air conditioning even more efficient. Specialized materials can also be used for plastic bottle-shaped objects if they meet the intended purpose. The installation location can be selected above ground, underground, semi-underground, or anywhere else depending on the purpose. Multiple underground tanks can be installed depending on the temperature. Plastic bottles and other structures are connected to allow water to flow through them. To achieve this, they are secured with adhesive tape or hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When further liquid is added to a temperature-controlled space created using such plastic bottles and fish are kept there, the structure should be as streamlined as possible to allow the fish to swim in large circles if they swim fast. Setting the width in the direction of movement to 50 cm or so based on the size of the fish ensures safety by preventing head-on collisions. Furthermore, by creating a height difference in such structures, electric pumps can be used to move the liquid from a lower position to a higher position, creating a directional water flow within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be temporarily stopped if necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing underground heat, etc., and an efficient space is created within the structure according to the size of the plants to be grown. The plants are then placed and grown inside the structure, and the structure is transported to a work area where they are cared for, with limited and controlled air circulation between the outside world and the plant. This prevents cross-pollination and complies with the Seed and Seedlings Act. A space isolated from the outside world is constructed using plastic bottles, etc., and this is connected to the space where the plants are grown with a hatch. After people enter and confirm that the space is clean, the connecting hatch is opened and the plants in the internal space can be cared for directly by a person or mechanically using a remote camera or a magic hand. Plants transported to the work area using rails or other means can be remotely monitored by a camera, and tasks such as thinning the plants can be performed automatically using installed machines through AI learning. When circulating liquids in a space constructed using materials such as PET bottles, the temperature of the liquid in an underground tank can be used to heat or cool the space. To further cool or heat the interior of the space, the circulating liquid can be artificially heated (using equipment such as an oil boiler) or cooled (using equipment such as a refrigerator or liquid nitrogen), but objects constructed using PET bottles can also be used as solar heat storage hot water systems, thereby saving on utility costs. By concentrating sunlight around an object constructed using PET bottles, protecting it with airtight materials such as aluminum, and adding insulation, the thermal efficiency can be improved. A structure constructed using materials such as PET bottles can be provided with a suitable internal space where plants can be grown. However, PET bottles circulate liquids such as water inside, and if that water is transported via pipes from an underground tank, it will transfer the underground temperature to the interior of the space. The PET bottles provide a shield between the temperature-transferring material (such as water) and the space. If liquids that utilize underground temperatures are not poured into PET bottles or the like, covering them with heat-retaining or insulating materials can reduce energy costs that would be incurred if the temperature inside the space were to be artificially adjusted with air conditioners or boiler equipment.When creating spaces inside structures made from plastic bottles or similar materials, if the lower spaces are blocked by objects placed inside the upper spaces, methods include first concentrating sunlight at an appropriate location and transmitting it to the necessary areas using optical fiber. Alternatively, mirrors can be used on the sides of the structure or elsewhere, where light is most likely to reach. These devices refract the light and guide it from areas that are more likely to receive it to areas that are less likely to receive it. Plastic objects like plastic bottles can be made transparent, allowing for the creation of open spaces that block light but can also be used as art by raising fish or other creatures inside. By using similar structures to change the size of the space and enlarge it, it is possible to fill it with hot water or other leisure facilities, creating a space that is integrated with nature. This allows for the creation of relaxing hot springs and other facilities without worrying about rain or wind. The temperature inside the space and the temperature of the liquids, such as the water, can be managed with sensors, automatically adjusting the flow rate of electric pumps, etc., to keep energy costs just right. If a facility is set up in a mountainous area, nearby timber can be used to effectively utilize the heat generated by combustion. In this way, by minimizing costs, market-competitive agricultural products can be produced and then distributed free of charge to poor young people, or a coupon-like certificate can be issued based on terms and conditions that provide certain services in return. Significant reductions in production and service costs can be achieved, and a coupon-like concept can be built based on patent rights or other assets. Coupons can also be viewed as a conceptual entity. Suppose Person A owns an agricultural production facility and also a restaurant or recreational facility, he or she can manage the usage fees with coupons and use them as fees for daily service businesses, exercising a community-like group to recruit participating businesses. Negotiate the use of these coupons with restaurants and recreational facilities run by other operators. Restaurants and recreational facilities can also earn payment by serving or selling agricultural products.Even if recreational facilities and other facilities require significant labor costs, these coupons can be used if they include the provision of such contracted services. We will strive to make these coupons available not only for recreational facilities but also for service industries and other businesses where payment is typically made in yen or other monetary terms. If Person A is a business owner and receives payment in yen for services, as is customary, this generates income, which could be collected by the government and distributed to the poor through welfare programs (such as welfare assistance). By having Person A and others participating in this system take on this role, we can raise awareness of basic human values, such as the meaning of receiving services, and reduce the government taxes associated with such work. We can ensure food, the foundation of human life, and enable people to live on it. By having farmers and service providers participate in this system, under Person A's management, farmers and other producers can be relieved of the anxiety of receiving only a very low relative value in the market, and service providers can feel the social significance of the coupon system, which is sufficient to justify their acceptance. We can create our own income redistribution system and build a stable society. Furthermore, since this coupon exists at the discretion of the individual, whether or not they participate is up to them. Therefore, if someone wants to participate, Person A can choose whether or not to allow them to do so, and can also decide on the terms and conditions of the agreement. Person A can decide whether to allow the coupon to be redeemed for cash. It can also be made so that redemption is only possible through Person A. Whether or not Person A redeems is at Person A's discretion. It can also be decided that coupons with different contents can be exchanged through Person A. Person A also has the right to exchange coupons and freely issue new coupons at their own discretion. Coupons are concepts. Coupons can be paper-based or digitized. By digitizing and encrypting them using PGP encryption or similar, and centrally managing the data in a database, Person A can understand the connections between goods, coupons, and services. Person A is free to decide whether to make this data public. Since it is based on a relationship of trust, it prevents interference by third parties and ensures stability. When coupons are replaced with virtual currency, the value of the currency can be determined in advance, such as the number of strawberries that can be eaten per coupon.It is also possible to stipulate in the contract that virtual currency exchange can only be done through person A. To cool, heat, or maintain the temperature inside a house or other object, water is stored in a tank installed underground or elsewhere and then channeled onto the roof of the house or other structure. Ground temperature approximately 5 meters underground is maintained at approximately 15°C year-round in Honshu, Japan, depending on latitude. A tank is installed there and filled with well water, etc., and then water is channeled to the roof or other structure using an electric pump or, if it is from a high point such as a mountain, water pressure is used to channel the water to the roof or other structure. The channeled water is then collected using gutters or other devices and returned to the tank. Tanks can also be partitioned to prevent the returning water from mixing with the water inside the tank until it cools to a certain extent. The height of the tank's threshold can be adjusted to control the amount of water that must accumulate before overflowing to the next tank or other location. Multiple tanks can be installed, with the returning water stored in a separate tank for a certain period of time, and then flowing back into the original tank when it becomes full. Partitions may not be necessary if the tank capacity is large or the amount of water being channeled is small. The amount of water flowing can also be adjusted by adjusting the output of the pump. Similarly, flowing water on roads can be used for cooling purposes in the summer and for melting snow and preventing freezing in the winter. The amount of water flowing can be programmed in advance using temperature data from weather forecasts, or the output of the pump can be controlled based on the actual temperature. If spring water or well water (such as spring water or well water, which maintains a stable temperature year-round) is used, a tank may not be necessary. To adjust the amount of water flowing, a valve or other device can be installed on the pipe leading to the roof, allowing for the diameter to be controlled, or a faucet can be used to control the amount of water flow by opening and closing it via a computer. While tanks do not necessarily need to be installed underground, using temperature-controlled water using ground temperature allows for temperature control inside homes with less water, reducing electricity costs for pumps and other equipment. Building a long, narrow tank at least 5 meters underground, with a larger volume at the deeper end, and circulating the water with a motor can help prevent freezing. Tanks can be installed underground and above ground and connected to mix the materials in the ratio that best suits the temperature conditions.Because temperatures vary depending on the depth underground, installing multiple tanks at different depths and connecting them with pipes to distribute the mixed water onto the roof of a house or other structure increases efficiency. When distributing water onto a roof, the water temperature and heat of vaporization must be calculated before distributing the most efficient amount. By piping water to the highest point on the roof, gravity will allow it to flow down the roof. Pipes can also be used to distribute water not only to the roof but also to the sides of the house (for example, pipes can be installed above windows to allow water to flow along the sides of windows). If the roof diameter is 5 meters, pipes on the roof of approximately 5 meters will allow water to flow across the entire roof. The pipes have holes at appropriate intervals (5 cm apart, but not necessarily 5 cm apart) from which the water will escape. Taking advantage of the fact that the ground temperature about 5 meters underground is around 15°C in winter, pipes can be installed under the flooring, on the sides, and in the ceiling of a house or other structure to circulate the water, collecting it in an underground tank for reuse. Hot spring water, for example, can be used to create even hotter liquids (hot water). To reduce the risk of patent holders being sued over their patents, patent holders must detail the entire process required for the patent, from start to finish, in the patent claims. If patent holders obtain a patent, they can minimize the risk of being sued for infringement by third parties or having to pay damages by using the patent in a manner that reproduces what is described in the patent. The patent must include a complete description of all manufacturing processes, materials, methods, and technical steps. The patent's implementation procedures, as well as all phenomena occurring in the materials and processes, must be described in writing in the claims. After a patent is granted, anyone can anonymously challenge the patent for six months. Patent attorneys, however, are also entitled to challenge this right and the confidentiality obligations stipulated in the patent rules. In this sense, they are considered to be involved parties who know the patent details earlier than the general public. People who have access to documents relating to the patent at the Patent Office will also know the contents of the patent before it is made public, so if such people start investigating long in advance, it could potentially give them an advantage. Therefore, we will convey our opinion to the relevant authorities to stop anonymous objections and ask them to change the rules. By connecting plastic bottle-shaped materials, a space can be created for people to pass through, allowing for temperature regulation. Plastic bottles and other materials can be connected and a liquid (such as water) with a constant temperature throughout the year can be stored inside, approximately 5 meters underground (approximately). This liquid can then be pumped inside using an electric pump or other device to provide air conditioning for high and low outside temperatures. Groundwater temperature also fluctuates throughout the year depending on depth, but this can also be utilized to its full potential for air conditioning. If the natural outside temperature is around 5°C and the structure is sufficiently shielded, the internal air temperature will approach this over time if the water is 15°C. Therefore, if the desired temperature is around 22°C, an additional 7°C of energy is required to maintain the air temperature, which is more efficient than raising the temperature from 5°C. The same is true for lowering the temperature. Hot water from hot springs or other sources can be used to further increase the temperature, making air conditioning even more efficient. Specialized materials can also be used for plastic bottle-shaped objects if they meet the intended purpose. The installation location can be selected above ground, underground, semi-underground, or anywhere else depending on the purpose. Multiple underground tanks can be installed depending on the temperature. Plastic bottles and other structures are connected to allow water to flow through them. To achieve this, they are secured with adhesive tape or hollowed out. The structural purpose is to create a barrier between the liquid and the outside air to maintain temperature. When further liquid is added to a temperature-controlled space created using such plastic bottles and fish are kept there, the structure should be as streamlined as possible to allow the fish to swim in large circles if they swim fast. Setting the width in the direction of movement to 50 cm or so based on the size of the fish ensures safety by preventing head-on collisions. Furthermore, by creating a height difference in such structures, electric pumps can be used to move the liquid from a lower position to a higher position, creating a directional water flow within the space containing the liquid in contact with the fish, preventing collisions. The water flow can also be temporarily stopped if necessary.A space constructed using materials such as plastic bottles is circulated with water or other liquids, utilizing underground heat, etc., and an efficient space is created within the structure according to the size of the plants to be grown. The plants are then placed and grown inside the structure, and the structure is transported to a work area where they are cared for, with limited and controlled air circulation between the outside world and the plant. This prevents cross-pollination and complies with the Seed and Seedlings Act. A space isolated from the outside world is constructed using plastic bottles, etc., and this is connected to the space where the plants are grown with a hatch. After people enter and confirm that the space is clean, the connecting hatch is opened and the plants in the internal space can be cared for directly by a person or mechanically using a remote camera or a magic hand. Plants transported to the work area using rails or other means can be remotely monitored by a camera, and tasks such as thinning the plants can be performed automatically using installed machines through AI learning. When circulating liquids in a space constructed using materials such as PET bottles, the temperature of the liquid in an underground tank can be used to heat or cool the space. To further cool or heat the interior of the space, the circulating liquid can be artificially heated (using equipment such as an oil boiler) or cooled (using equipment such as a refrigerator or liquid nitrogen), but objects constructed using PET bottles can also be used as solar heat storage hot water systems, thereby saving on utility costs. By concentrating sunlight around an object constructed using PET bottles, protecting it with airtight materials such as aluminum, and adding insulation, the thermal efficiency can be improved. A structure constructed using materials such as PET bottles can be provided with a suitable internal space where plants can be grown. However, PET bottles circulate liquids such as water inside, and if that water is transported via pipes from an underground tank, it will transfer the underground temperature to the interior of the space. The PET bottles provide a shield between the temperature-transferring material (such as water) and the space. If liquids that utilize underground temperatures are not poured into PET bottles or the like, covering them with heat-retaining or insulating materials can reduce energy costs that would be incurred if the temperature inside the space were to be artificially adjusted with air conditioners or boiler equipment.When creating spaces inside structures made from plastic bottles or similar materials, if the lower spaces are blocked by objects placed inside the upper spaces, methods include first concentrating sunlight at an appropriate location and transmitting it to the necessary areas using optical fiber. Alternatively, mirrors can be used on the sides of the structure or elsewhere, where light is most likely to reach. These devices refract the light and guide it from areas that are more likely to receive it to areas that are less likely to receive it. Plastic objects like plastic bottles can be made transparent, allowing for the creation of open spaces that block light but can also be used as art by raising fish or other creatures inside. By using similar structures to change the size of the space and enlarge it, it is possible to fill it with hot water or other leisure facilities, creating a space that is integrated with nature. This allows for the creation of relaxing hot springs and other facilities without worrying about rain or wind. The temperature inside the space and the temperature of the liquids, such as the water, can be managed with sensors, automatically adjusting the flow rate of electric pumps, etc., to keep energy costs just right. When installed in mountainous areas, nearby wood can be used to heat surrounding water or other materials, effectively utilizing combustion heat and exhaust gases from wood. Plants can be grown in structures constructed using materials such as plastic bottles. Since the interior of the structure does not require human access, plants can be transported there on pallets by pulling them using wheels or rails, or by connecting them like a train using a motor. The same process is used for retrieving them. Pipes can be used to connect the exterior of the structure to a tank approximately 5 meters underground (the depth can be varied based on temperature, and water from tanks of different depths can be mixed. The water itself can also be heated using a heater). Water drawn from the tank using a motor pump or similar can be poured onto the exterior of the structure. By constructing the structure's exterior with steps, liquid water or coolant can be poured at the highest point of the structure, maintaining different temperatures around the structure rather than having it fall all at once. This allows the structure to be cooled or heated. Pipes for conveying water can be installed in appropriate locations within the structure, and water can then be returned to the underground tank.When constructed using PET bottles, holes can be drilled in the sides of the bottles when connecting them vertically or horizontally, allowing for the water inside the bottles to be freely moved. While structures constructed using PET bottles can be filled with water and circulated between tanks using a motor pump or other power source, they can also be filled with antifreeze (clear is usually better, but colored is acceptable in some cases) suitable for insulation, water, glass, marbles, plastic resin, or other light-transmitting materials (colored materials are sometimes preferable to adjust the amount of sunlight; a light-blocking cover can also be placed on the exterior). Water from underground tanks or hot springs can be channeled outside the structure, collected, and returned, as described above, to regulate the temperature inside the structure. This can sometimes reduce the construction cost and strength of the structure. PET bottle structures are not limited to PET bottles; specialized materials can also be used. One use for these structures is to separate the interior space constructed using PET bottles from the outside air.

This can sometimes reduce the construction cost and strength of the structure. PET bottle structures are not limited to PET bottles; specialized materials can also be used. One use for these structures is to separate the interior space constructed using PET bottles from the outside air. When creating a multi-purpose space inside a structure using plastic bottles or other materials, if liquid poured from above moves due to gravity, gaps can be created between the bottles or by creating a certain height difference at the edge of the structure to control the movement of the liquid and increase the efficiency of the liquid's temperature being transmitted to the space inside. By filling multiple or single tanks underground at high altitudes with natural spring water, hot spring water, river water, etc. and then using pipes to transport the water via gravity to a plastic bottle structure at a slightly lower elevation, electricity costs for pumps and other equipment can be almost eliminated, making it eco-friendly (theoretically, renewable energy alone is also possible). When filling a space constructed using plastic bottles with liquid and allowing fish to swim, streamlining the swimming area of ​​the structure reduces the risk of the fish colliding with obstacles. A large loop can also be created overall, using pumps and fans to generate water pressure and generate water currents within the space. Creating a space with a gently curved structure constructed from a large circle can prevent fish from coming into contact with walls.Keeping the width of the space for fish to swim around 50 cm (this is only a guideline and depends on the size of the fish) can prevent them from colliding with the sides. Spaces for heat control using groundwater and spaces for temperature regulation using this can be created by arranging structures using plastic bottles, etc., inside which temperature-regulating liquids can be placed, and surrounding spaces can be placed plants that utilize the liquid, or spaces that humans can enter. The arrangement can be freely selected. By placing a structure made of plastic bottles, etc., with spaces of various sizes inside it, in an aquarium set to a certain temperature, the temperature of the liquid filled in the aquarium will affect the space in the object made of plastic bottles, thereby regulating the temperature of that space. The space can be sealed, or air can be introduced or removed through a filter. The present invention aims to solve the above-mentioned problems by providing a constant-temperature water (liquid, heat-transmitting substance) utilization device that can utilize the benefits of nature regardless of the weather. To achieve the above-mentioned problems, the constant-temperature water utilization device of the present invention (which may be a liquid, heat-transmitting substance, coolant, or other substance) utilizes constant-temperature water and includes: an underground tank buried underground where a predetermined constant underground temperature is maintained and stores constant-temperature water; a structure formed by communicating and connecting multiple hollow tubes made of a light-transmitting material to form a cavity inside; a pipe and a circulation pump that circulate the constant-temperature water stored in the underground tank through the hollow tubes of the structure; and a fan that blows air from one end to the other end of the cavity formed by the structure, wherein the cavity is used as an air-conditioning space or a space for installing energy exchange equipment. This configuration allows for effective use of constant-temperature water, etc. Another aspect of the present invention is a constant-temperature water utilization device that utilizes constant-temperature water, comprising: an underground tank buried in a predetermined underground location where a predetermined constant underground temperature is maintained and storing constant-temperature water; a conduit that conducts the constant-temperature water stored in the underground tank to the vicinity of a conduit; and a plurality of pipes connected to the conduit and buried at a predetermined depth from the road surface to maintain the temperature at the conduit surface at the predetermined temperature with the constant-temperature water. The geothermal energy is liquefied (using water, etc.) in a tank installed underground (which may be installed at multiple points at different depths) and transported to a target location to control the temperature of a target object, location, etc. This configuration allows for effective use of constant-temperature water.Another aspect of the present invention is a constant temperature water utilization device that utilizes constant temperature water, comprising: an underground tank buried underground where a predetermined constant underground temperature is maintained and stores constant temperature water; a wall formed by connecting a plurality of hollow tubes in a planar shape; a structure formed by using the wall to form a cavity; and a pipe and a circulation pump that circulate the constant temperature water stored in the underground tank through the hollow tubes of the structure, wherein the cavity is used as an air-conditioning space. With this configuration, the constant temperature water can be effectively utilized. Another aspect of the present invention provides a trolley for transporting automobiles by traveling on rails on which an ice surface of frozen liquid is formed. The trolley comprises: a trolley body supporting the weight of the automobile to be transported; a plurality of sleds attached to the underside of the trolley body for sliding on the ice surface; a drive unit for driving the trolley body; a position information acquisition means for acquiring position information of the trolley body along the rail; and a control device for controlling the drive unit based on the position information acquired by the position information acquisition means to drive the trolley body to the destination. This configuration allows automobiles to be transported energy-efficiently through inertial motion by sliding on the ice with little resistance, and also allows the driver of the automobile to rest during the transport. (Constant Temperature Water Utilization Apparatus) A constant temperature water utilization apparatus according to one embodiment of the present invention will now be described with reference to the drawings. Next, a constant temperature water utilization apparatus 6 according to one embodiment of the present invention will be described with reference to FIG. 1. The constant temperature water utilization apparatus 6 utilizes constant temperature water. The constant-temperature water utilization device 6 includes an underground tank T, a structure 60, a pipe 62, 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 constant-temperature water. For example, in Japan, an underground space 5 meters underground has a constant underground temperature environment of about 15°C throughout the year, and the constant-temperature characteristics of such underground spaces can be utilized as a blessing from nature. The temperature of the underground space can be a constant temperature space within various temperature ranges depending on the surrounding environment, such as a hot water-containing layer such as a hot spring or a groundwater layer of meltwater.By selecting such an underground space and installing an underground tank T, constant-temperature water at a predetermined temperature can be stored and used. In this invention, the term "water" in the constant-temperature "water" stored and used in the underground tank T is used as a broad, general term that encompasses any other liquid that can be substituted for water. The constant-temperature "water" stored and used 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 constant temperature, for example, near a groundwater layer containing constant-temperature groundwater at a predetermined temperature. Once installed in a predetermined location, the underground tank T is filled with water to a predetermined full capacity. The water stored in the underground tank T may be groundwater at the tank installation site, or, for example, tap water may be injected from above ground. By injecting water close to the original temperature of the underground space where the underground tank T is installed into the underground tank T, the constant-temperature water can be used more quickly. Water stored in underground tank T is pumped from underground tank T to the surface by water pump P2. The water stored in underground tank T is used as constant-temperature water, then transferred to the underground space, where it is returned to constant-temperature water. It is then returned to underground tank T and reused as constant-temperature water. Structure 60 has a cavity 61 formed by connecting and communicating multiple hollow tubes 6a made of a light-transmitting material. Cavity 61 is used as an air-conditioning space or a space for installing energy exchange equipment. Structure 60 may be installed above ground when used in sunlight, or underground in other cases. Installing it underground facilitates use at a predetermined constant temperature. Structure 60 is used as an enclosed space by sealing both ends with walls formed by connecting hollow tubes 6a. Structure 60 may also be used as an open space with portions of both ends open. The pipe 62 and the circulation pump P3 are used to circulate constant-temperature water stored in the underground tank T and pumped up by the water 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 required amount of constant-temperature water is stored in the auxiliary tank T1, circulated through the hollow tube 6a, and then returned to the underground tank T.The constant-temperature water utilization device 6 includes a recovery device that returns used water extracted from the underground tank T to the underground tank T. The recovery device includes a pipe 69 connecting the structure 60 and the underground tank T and a recovery tank Ts attached to the underground tank T. A water recovery pump may be provided along the pipe 69. The recovered water has a temperature different from the temperature of the underground space in which the underground tank T is installed. Therefore, the recovery tank Ts is used to return the temperature of the recovered water to the temperature in the underground space, i.e., a constant temperature. In this embodiment, the recovery tank Ts is attached to the underground tank T, but they may also be separate and connected by a pipe. The recovery tank Ts may also include a heat exchanger configured to allow the recovered water to quickly return to the temperature in the underground space. Furthermore, if the amount and temperature of the recovered water, i.e., the heat content, are small and negligible compared to the heat content of the constant-temperature water in the underground tank T, the recovered water may be directly mixed with the constant-temperature water in the underground tank T, since temperature fluctuations are negligible. The configuration of the pipe 62, circulation pump P3, auxiliary tank T1, and other components for circulating and utilizing water from the underground tank T is merely an example, and is not limited to the illustrated configuration. Pipes, pumps, auxiliary tanks, valves, and other control devices may be included as needed. The auxiliary tank T1 is not required, but may be included as needed. The fan 63 generates airflow in the sealed cavity 61 formed by the structure 60. This airflow eliminates stagnation within the cavity 61. Heat generated in the cavity 61 is carried to and absorbed by the wall surface of the hollow tube 6a by the airflow from the fan 63. The structure 60 may be provided with external piping from one end to the other to form a closed air passage, and the airflow from the fan 63 may generate a unidirectional circulating airflow within the structure 60. The cavity 61 is preferably used as an installation space for a solar panel 64, as shown in FIG. 2. The solar panel 64 is an energy exchange device that converts solar energy into electrical energy. The solar panel 64 is placed in a cavity 61 whose four sides are maintained at the temperature of the groundwater, and air is blown by a fan 63, so that the panel surface can be kept at an appropriate temperature and power generation efficiency can be maintained.This mechanism can be used to maintain an appropriate temperature for any object, not just solar panels. The structure 60 can be shaped so that the cavity 61 can be optimized and efficiently controlled depending on the contents to be contained therein. For example, in the case of a solar panel 64 shown in FIG. 2, the cavity 61 can be sealed by surrounding the outer periphery of the panel, including the front and back surfaces, with a wall formed by a hollow tube 6a, so that the panel can be contained in the smallest possible space. Alternatively, the cavity 61 can be partially open rather than completely sealed. Next, referring to FIG. 3, an application example of the constant-temperature water utilization device 6 will be described. This constant-temperature water utilization device 6 includes multiple (three in the illustrated example) underground tanks T and a mixer 6mx that mixes water of known temperatures from each tank. The underground tanks T are individually buried at multiple depths underground or in different underground environments so that they can store constant-temperature water at different temperatures t1, t2, and t3. The mixer 6mx mixes the constant-temperature waters at different temperatures t1, t2, and t3 obtained from the multiple underground tanks T to deliver 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 varies seasonally over the long term throughout the year. According to this embodiment, even if the temperature of each stored water varies seasonally, the predetermined temperature can be maintained by changing the mixing ratio in consideration of the temperature difference between the water stored in each underground tank T. (Another Embodiment of the Constant-Temperature Water Utilization Device) Like the above embodiment, this device utilizes constant-temperature water and uses an underground tank T buried in a predetermined underground location where a predetermined constant underground temperature is maintained to store constant-temperature water. In addition to the underground tank T, the constant temperature water utilization device of this embodiment is equipped with a conduit that leads 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 that are buried at a predetermined depth below the road surface to maintain the temperature at the conduit surface at a predetermined temperature with the constant temperature water.According to this embodiment, even in existing roads, in order to prevent freezing and lower the road surface temperature in summer, an underground tank T is installed 5 meters underground or below or near a road or walkway, and constant-temperature water stored in the underground tank T is transported using pipes or the like and circulated 10 centimeters below the road's asphalt, thereby preventing the road surface from freezing or emitting excessive heat. (Further Another Embodiment) A device in yet another embodiment is a constant-temperature water utilization device that utilizes constant-temperature water, similar to the above embodiments, and uses an underground tank T that is buried underground in a predetermined area where a predetermined constant underground temperature is maintained and stores constant-temperature water. In addition to the underground tank T, the constant-temperature water utilization device of this embodiment includes a wall formed by connecting multiple hollow tubes in a planar manner, a structure formed by using the wall to form a cavity inside, and pipes and a circulation pump that circulate the constant-temperature water stored in the underground tank through the hollow tubes in the structure, with the cavity being used as an air-conditioned space. In this device, a pipe, a recovery pump, a recovery tank, and a tank are provided for pumping out the water from the underground tank T and recovering it after use. The hollow tube may be transparent or non-transparent, and a portion of the hollow wall may be transparent to provide a skylight. The optimal air-conditioning space can be configured depending on the application. According to this embodiment, a futon-sized space (the size of the space can be changed, even larger or smaller) can be created as an air-conditioning space, maintaining a cool temperature in the summer and above freezing in the winter. Furthermore, by using a motor to pump water, installing it underground on a high mountain, or using a large underground tank connected to a large-scale facility such as a water purification plant to deliver cold water at a temperature close to 15°C even in the summer to each household, the constant-temperature water in the underground tank T can be utilized solely through water pressure. (Cart Traveling by Sled) Next, a cart according to one embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 4 and 5, cart 8 travels on a pair of left and right rails 23 on which a frozen liquid ice surface 2a is formed, transporting a cart 90. The dolly 8 includes a dolly body 80 that supports the weight of the automobile 90 to be transported, multiple sleds 81 that are attached to the underside of the dolly body 80 and slide on the ice surface, and a drive unit (traveling wheels 85) that moves the dolly body 80. In this embodiment, the dolly 8 further includes a transportation sled 84 on which the rear wheels 9b of the automobile 90 are placed and which slide on the ice surface 2a. To share the weight of the automobile 90 with the rail 23, the dolly body 80 is placed with the front wheel 9a that is not placed on the transportation sled 84. Whether the front wheel 9a or the rear wheel 9b is placed on the dolly body 80 can be selected arbitrarily depending on the characteristics of the automobile 90. The dolly 8 further includes a position information acquisition means 82 that acquires position information of the dolly body 80 along the rail 23, and a control device 83 that controls the drive unit based on the position information acquired by the position information acquisition means 82 to cause the dolly body 80 to travel to the destination. The carriage 8 is equipped with a braking device for controlling travel. A pair of left and right rails 23 guide the ice sled 81 as it slides on the ice, and the ice surface 2a is formed by freezing a liquid. The rails 23 have a housing with a concave cross section with a groove formed in the longitudinal direction and are fixed to the road surface 20, and a refrigerant pipe arranged inside the groove for passing a refrigerant. Water is poured into the groove of the housing and is 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 provided with a cover to prevent rain and other elements from entering the interior when the sled 81 is not sliding on the ice, and may also be provided with drain holes to drain water present on the ice surface 2a. The housing for this cover and the rail 23 is preferably configured to circulate water from an underground tank through pipes, for example, to improve cooling efficiency. Guide wheels may be provided on the lower part of the bogie body 80, close to the outer surface of the rail 23. The guide wheels guide the bogie body 80 so that the bogie 81 runs along the rail 23. Such a guiding device may be provided between the sled 81 and the rail 23. For example, a structure on the rail 23 may be configured to encase and surround the sled 81 to prevent it from deviating 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 be able 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 moving upward, the bogie body 80 sleds on the icy surface 2a using the sleds 81. When driven, the running wheels 85 contact the road surface 20, causing the bogie body 80 to travel. The running wheels 85 also serve as a braking device. The bogie 8 may be configured to move the bogie body 80 using a drive unit that does not have running wheels 85. For example, a jet propulsion unit or a propeller propulsion unit may be mounted on the bogie body 80 as the drive unit. A linear motor may also be used as the drive unit. In this case, the track that forms the magnetic field of the linear motor may be covered with a frozen liquid to form an ice surface. A linear motor may also be combined with running wheels 85 that obtain driving force from an engine or motor mounted on the bogie body 80 to form a drive unit. The position information acquisition means 82 may be configured, for example, using a sensor that acquires position information by successively detecting position signs or markers provided along the rail 23, or may be configured to acquire position information using a GPS function, or may be configured as a combination of these. The braking device may be configured as a braking device for a normal tire-driven vehicle, in which the running wheels 85 that constitute the drive device are installed on the road surface 20 to brake.The braking device may be a braking device that does not use traveling wheels 85, but rather a device that applies braking by interaction with the rail 23. For example, a device configured to sandwich a brake plate provided on the side wall of the rail 23 between brake shoes provided on the lower part of the bogie body 80 may be used. Alternatively, non-contact braking may be applied by electromagnetic interaction between a coil arranged along the rail 23 and a coil arranged on the lower part of the bogie body 80. Furthermore, as a device that applies braking without direct interaction with the rail 23, a wind receiving plate may be provided on the bogie body 80, and braking may be performed by wind pressure when the wind receiving plate is expanded. The control device 83 controls the travel of the bogie body 80 using the above-described braking device, and causes the bogie body 80 to travel to the destination based on position information obtained by the position information acquisition means 82. The control device 83 selects an appropriate route and controls travel based on the position information obtained by the position information acquisition means 82, even when the rail 23 branches. According to the bogie 8 of this embodiment, the driver of the automobile can leave the transportation of the automobile to the bogie 8, and can take a break or do something other than driving during the transportation. The bogie 8 of the present invention is not limited to a configuration including the above-mentioned transportation sled 84, but may be configured so that the entire automobile 90 is mounted on the bogie main body 80. Furthermore, the drive device is not limited to one using the running wheels 85, but may be configured to use a rocket propulsion device, a propeller propulsion device, or a jet propulsion device. (Bogie According to Another Embodiment) Next, with reference to FIG. 6, a bogie 8 according to another embodiment will be described. The bogie 8 of this embodiment is configured so that the entire automobile 90 is mounted on the bogie main body 80 and travels using the driving force of the automobile 90, and is otherwise similar to the bogie 8 of the above embodiment. The drive device of the bogie 8 of this embodiment is equipped with a rotation transmission device 86 that receives the rotational force of the drive wheels (front wheels 9a in this example) of the automobile 90 mounted on the bogie main body 80 and transmits it to the running wheels 85. The rotation transmission device 86 includes a rotatable roller that supports from below the front wheel 9a, which is driven and rotated by the automobile engine, and a transmission mechanism that transmits the rotational energy of the roller to the traveling wheels 85. According to the dolly 8 of this embodiment, it is possible to travel using the power of the automobile 90 that is being transported, without having to include a motor or engine for driving the traveling wheels 85.The driver of the car can move along with the car 90, relying on the cart 8 to move. (Note) (Movement: sled, cart) Taking advantage of the natural law that the temperature around 5 meters underground in mainland Japan remains at around 15 degrees throughout the year, building a tube-shaped tunnel on the ground there can save energy required for cooling. Alternatively, this structure can be installed above ground and the outer periphery of the tube can be covered with liquid water for cooling. If the outer periphery of the tube is made of transparent plastic or glass, the scenery can be viewed from inside the car. A similar tunnel could be filled with water or other liquids to run a sealed ship, creating a vacuum inside the tunnel and increasing energy efficiency during travel (this can be applied to anything that can travel through a tunnel). Using a similar structure for cars, not just large vehicles like trains, can reduce energy costs, etc. This increases the reliability of autonomous driving. By connecting a car to a cart installed on a similar platform, the weight of the car would be primarily supported by the sled, reducing rolling resistance. There are various methods, such as incorporating a motor or the like in the cart to contact the road surface and transmit power, or connecting the power of the engine or motor of an automobile or the like from the tires, engine, motor, etc. of the automobile to the power section of the cart while the automobile or the like is mounted on the cart, or equipping the cart with a device to transmit the rotational force of the wheels of the automobile or the like to the road surface as needed. Also, even if an existing car or the like is not used, if a four-wheeled vehicle, two more wheels or so can be attached to the center of the body in advance, and these parts do not come into contact with the ground during normal driving, but can be structured so that they come into contact with the ground by changing the angle, etc. using hydraulics, etc., and using the four wheels to ride on the cart, and the remaining two wheels (rubber, steel, etc.) can be brought into contact with the upper part of the cooling rail using hydraulics, etc. as needed, or giving the cart the function of a hydraulic jack so that after the automobile or the like rides on the cart, the car can be raised or lowered using hydraulics, etc., to change the height of the car's tires, etc., so that it does not come into contact with the ground, etc. This bogie can be equipped with a motor or the like to provide driving force when running, or some of the bogies can be powered to pull or push and be connected to other bogies like a train, or powered bogies can be appropriately arranged to reduce installation costs.The movement of the trolley (unit) can be monitored with sensors, and cameras can be installed around the cooling lane, allowing the trolley to be controlled automatically and unmanned. Solar panels can be installed near the space where such cooling lanes are installed, and electricity from them can be transmitted from the metal parts of the lane to the motors of the trolleys, or contactless power transmission can be used so that the lane and the electrical receiving part of the trolley do not have to come into direct contact. There are several methods, such as attaching a device to the side of a vehicle's tire to connect to the tire (which can be a steel wheel) so that its rotation does not come into contact with the road surface or the ice-free top of the cooling rail on the trolley, converting the energy of the vehicle's engine, motor, etc. into propulsion energy, or attaching a device to a trolley with a roller part that rotates in response to the rotation of the tire by rotating the engine, etc., without changing the position of the vehicle passing through inspection, and connecting it to a wheel with a mechanism that converts the rotational energy of the roller part so that the wheels of the trolley do not come into contact with the road surface. To prevent the road surface from freezing, water stored 5 meters underground and heated to approximately 15 degrees Celsius by geothermal heat is piped to the road surface. The water is then collected by a motor pump and collected in a tank for circulation. For emergency stops, stakes are installed at the rear of the bogie, and if necessary, they can be lowered to the road surface for quick stopping. Even when using technologies such as linear motor cars to obtain energy in the direction of travel, cooling the magnetic field of the linear motor car's tracks to cover them with ice and installing sleds or other devices to reduce resistance during travel can save on vertical levitation power and concentrate most of the electrical energy in the direction of travel, making it more efficient. The levitation energy and acceleration energy in the direction of travel are balanced to maximize efficiency by reducing levitation energy to conserve as much electrical energy as possible by adjusting the direction of the applied magnetic energy. Even if the car does not actually float, the sleds reduce resistance and allow it to travel. For the sake of ride comfort, it is also possible to sprinkle a small amount of water on the frozen surface.A sled and the above-mentioned powered wheels may be attached to the linear motor car. The tunnel may be made into a near-vacuum state to eliminate losses due to wind and reduce noise, etc. The magnetic energy transmission part of the linear motor car and the sled device may be installed separately. Wings may be attached to the top of the vehicle to lift it. By gaining power and controlling air resistance, it is possible to further reduce and adjust friction with the icy lane, thereby reducing the frictional force acting on the vehicle's sleds against the cooling lane, or conversely, pushing the vehicle down the cooling lane. To prevent sleds from derailing from the cooling lane, the cooling lane can be shaped like a zipper, allowing the sled to fit into it. The direction of the wings can be changed or the balance of lift can be adjusted left and right to make it easier to turn. Flaps can also be adjusted to increase air resistance when decelerating. In emergency stops, a parachute can be deployed from the vehicle. To prevent the parachute from getting tangled, a device with a parachute attached can be detached from the rear of the vehicle and moved along the lane, allowing the vehicle to safely stop while still receiving the parachute's effects. The parachute device is connected to a device moving on the cooling lane by wires, and the device and the vehicle are also connected by wires. Various energy sources for such vehicles can be considered, such as wheel drive, jet engines, or propellers attached to the sides or rear of the vehicle. After accelerating considerably, the sled could then head skyward and launch itself into orbit, gliding or using a jet engine or rocket attached to the vehicle or lift from wings to move at high speeds. It could also be used to launch satellites into orbit while saving fuel. One method would be to accelerate the sled sufficiently on a cooling rail and launch it upward, then detach the satellite (using compressed gas pressure, for example) and further accelerate it using a jet engine. It would also be possible to use a jet engine or rocket to accelerate it on a cooling rail from the start. To cool the contact points of the sled, elongated heat-absorbing plates from a freezer could be placed there, or a dedicated heat-absorbing device could be used, or efficient temperature control could be achieved using a large compressor and underground water at a constant temperature. The waste heat from the compressor could also be used to power a Stirling engine. Water drawn from a depth of 5 meters or so underground could be circulated around the compressor using pipes, allowing for heat exchange where needed, thereby reducing heat dissipation.To cool the water in the cooling lane, pipes are installed nearby and non-humidified gases are introduced into them. Cooled 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 outlet to suck in the gas. After collecting the carbon dioxide at one end, another pipe can be used to flow the cooling gas in the opposite direction, saving storage space for carbon dioxide. Fans can also be installed midway along the pipe as needed. Carbon dioxide collected through the pipe can be reused as dry ice. Carbon dioxide can also be obtained by heating dry ice in a vacuum, which can then be introduced into the pipe. The speed can be increased by compressing the gas before sending it to the pipe. Even on existing roads, to prevent freezing and lower road surface temperatures in the summer, water stored in tanks installed 5 meters underground beneath roads and walkways can be circulated through pipes approximately 10 cm below the asphalt to prevent the road surface from freezing or overheating. Pipes can be used to circulate circulating water around the sled, improving cooling efficiency in the summer. Plastic bottles or similar items can be used to create a futon-sized space (the size can be larger or smaller, and can be adjusted) to maintain a cool temperature in the summer and above freezing in the winter. Water from a tank installed about 5 meters underground can be placed inside the bottles through pipes, and the bottles can be connected so that the water circulates and returns to the tank. Water can be pumped using a motor, installed underground on a high mountain, or connected to a large-scale facility such as a water purification plant. A cool tank can be installed to send water to each home at a temperature of approximately 15°C, even in the summer, allowing water to be pumped using only water pressure. Sealed covers can be attached to the top of cooling rails (lanes) and water from underground tanks at around 15°C can be circulated through these, reducing the cost of cooling towers. In order to minimize heat exchange, cooling rails, lanes, etc., the top covers are closed electrically, especially in the summer, but when vehicles pass, they are detected by sensors and can be opened and closed automatically by a motor, etc. (Additional Note) (Movement: Sled) In order to make an emergency stop of a train, etc., pipes are installed under the train tracks and oil, etc. (or gas, etc., with viscosity taken into consideration) is poured into them.A hole is then drilled in the top of the pipe, and a stake or similar object is dropped from the train or other vehicle to hook it into place. The point where the stake falls can be contacted with a round plate or similar object placed as close to the pipe as possible to prevent pressure from escaping, like an air gun, and this increases the pressure inside the pipe, slowing the train or other vehicle's speed. If multiple pipes are installed and there are multiple stakes on the train or other vehicle, one stake (a rod-shaped object used to hook a vehicle to the outside) can be hooked first, followed by a second or third stake, adjusting the braking force applied to the train. Holes or similar objects can be drilled in various places along the pipe to release pressure, and when a certain pressure is reached, a plug or similar object is released, preventing the pipe from breaking due to sudden excessive pressure. To reduce the train's air resistance, the train's doors can be made to lift up, allowing passengers to board and disembark through them to lower the vehicle height. When the pressure in a pipe filled with liquid or gas, such as a curved one used for braking, exceeds a certain level, it is released (or the stopper is removed mechanically (a device that can remotely open and close a door installed to allow the passage of liquid or gas inside the pipe, etc.)), or by creating a hole in another pipe, a pipe that can pass liquid or gas is connected, and a pressure reducing stopper or another dedicated hole is created in the adjacent section, and when pressure is applied, the liquid or gas moves to that section, thereby increasing the braking force. Normally, pipes contain a moderate amount of liquid or gas, preventing sudden shocks to vehicles. If necessary, a dedicated device (such as a hydraulic pump) can be prepared to pump liquid or gas into the pipes, allowing oil, liquids, or solids to be quickly pumped to the required sections as needed. When connecting a vehicle to a stake or other object (the hooking structure) to reduce the impact on the vehicle, shock absorbers such as springs or hydraulic shock absorbers can be installed between the vehicle and the stake. When freezing water or other liquids in the cooling lane, gases such as carbon dioxide can be filled into the pipes, and compressed or blown dry ice vapor can be pumped in under pressure.The ice is then collected at the end of the pipe, rehydrated into dry ice or at a very low temperature before solidifying, and then returned to its original position via another pipe for reuse. (Note) (Movement: Sled) When using cooling rails and sleds to slide vehicles, the lanes can be coated with a rough material, or the wheels can be covered with rubber or rubber tires can be used to ensure a secure grip on the wheels that transmit power. Superconducting magnets or magnets can also be installed on the sides or underside of the vehicle, and coils can be installed on the sides or center of the lane to generate electricity. Coils can also be installed on the vehicle, and magnets can be installed on the lane. Batteries can also be installed on the vehicle to power the drive motor and charge the generated electricity. Electromagnetic force, like in a linear motor car, can also be used to balance the sides. A vehicle using this cooling lane and a linear motor car can be operated together, and the electricity generated by the vehicle using the cooling lane can be used to power the linear motor car. (Note) (Underground tank) In order to cool solar panels, etc., water kept at a constant temperature in an underground tank like the one mentioned above is flowed over the panels, or a pipe-like structure made of a light-transmitting material is installed nearby and water of about 15°C from an underground tank (such as in Honshu, Japan, which is kept at a nearly constant temperature all year round at 5 meters underground. The temperature varies depending on the well, so a similar effect can be achieved by changing the depth) is flowed into it to control the temperature of the solar panels, or the solar panels are made waterproof and airtight and attached to a tub or similar filled with shallow water, and water of about 15°C installed about 5 meters underground is flowed into the tub and then collected back into the underground tank. In this case, in order to keep the target object (there are no particular restrictions, it can be any other substance or object) such as a solar panel at an appropriate temperature, pipes or the like can be placed around the target object to control the temperature. In this case, it is not necessary to use a fan to blow air, and the underground tank's constant underground temperature of about 15°C can be used to control the heat around the object or substance that needs to be kept at an appropriate temperature by using water or other liquid (coolant is also acceptable) as a medium, and then transporting the water through pipes or other means.To maintain an appropriate temperature for a target object (such as a solar panel), a system can be constructed in which liquids, such as water or coolants, flow around the object (such as a solar panel) in a way that retains heat and is tailored to the object's dimensions. The liquid then travels through pipes and is collected in a tank located 5 meters underground, where it cools down compared to the outside air temperature in summer and warms up in winter due to ground temperature. A system can be constructed to control the temperature of the panel. Using a plastic bottle or similar object, for example, cut out the top of the bottle and glue multiple rectangular cubes together to create a structure that can hold water from an underground tank. Using a material like a plastic bottle that allows light to pass through but not water, a hollow structure can be created filled with water. The hollow space can then be used to place items such as solar panels or other items whose temperature needs to be controlled. This system can also be used to increase the power generation of solar panels installed in homes, as power generation decreases when the solar panel becomes too hot. In addition, water at approximately 15°C from the underground tanks mentioned above is used to efficiently air-condition the space. Because the ground temperature around the underground tank varies depending on the depth, multiple tanks can be installed at different depths, and the water can be mixed. (Note) Even in existing roads, to prevent freezing and lower road surface temperatures in the summer, water stored in tanks installed 5 meters underground or so beneath roads and walkways can be circulated through pipes to 10 cm below the asphalt to prevent the road surface from freezing or overheating. Circulating water can also be piped around the sleds to improve cooling efficiency in the summer. Using plastic bottles or other materials, a futon-sized space (the size can be adjusted to be larger or smaller) can be created to maintain a cool temperature in the summer and above freezing in the winter. Water from a tank installed about 5 meters underground can be piped inside the bottles, and the bottles can be connected to allow the water to circulate and return to the tank.Water can be pumped using motors, installed underground on high mountains, or sent to homes in large underground tanks linked to large-scale facilities such as water purification plants, where the temperature is close to 15°C even in the summer, allowing water to be pumped using only water pressure. The cost of cooling towers can be reduced by attaching a sealed cover to the top of cooling rails (lanes) and circulating water at about 15°C from underground tanks. The top covers of cooling rails and lanes are closed electrically, especially in the summer, to minimize heat exchange, but when vehicles pass by, they can be detected by sensors and opened and closed automatically by a motor. Objects, for example. For transportation, the wheels of trains and other vehicles are replaced with sleds. Instead of railroad tracks, a space wide enough for the sleds to pass through is provided, and water or other materials are placed in that space, cooled and frozen using electricity or other means, to reduce friction and minimize energy loss. Wheels are placed in contact with the gaps between the rails and used during acceleration and deceleration. These wheels can also be retracted into the car body using electricity to prevent contact with the ground when the vehicle gains speed, reducing resistance. The sleds slide over frozen road surfaces, but have a rail structure with a protruding shape to prevent them from running sideways. To reduce impacts on curves, the sleds can be fitted with tires that contact the side of the rails. The track can be designed to slope slightly downward, with gravitational energy providing acceleration. While the track can be designed without elevation changes, even if construction costs are considered and an uphill track is chosen, the sleds reduce friction, allowing inertial energy to be used as a source of energy to move objects to higher ground. Even on a slight downward 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 provided by the tires in contact. The same is true for linear motor cars, which are not in contact with the ground. Air resistance can also be prevented by creating as much of a vacuum as possible inside the tube-like tunnel that surrounds the vehicle. Possible methods include opening hatches on the vehicle when it arrives at a station, creating a connecting passage with the outside, or installing partition hatches or other doors that open and close vertically within the tunnel, allowing air to enter sections such as stations, allowing passengers to enter and exit through them. In case rain gets into the cooled road surface, holes can be opened on the sides or rain shelters can be installed. Taking advantage of the natural law that the temperature about 5 meters underground in mainland Japan remains at around 15 degrees Celsius throughout the year, building a tube-like tunnel on the ground there would save energy required for cooling. Alternatively, when this structure is placed on the ground to cool it, the outer periphery of the tube can be covered with liquid water or the like, and if the outer periphery of the tube is made of a light-transmitting material such as plastic or glass, the scenery can be seen from inside the vehicle.It is also possible to fill similar tunnels with water and run sealed ships inside, creating a vacuum inside the tunnel and increasing energy efficiency during travel (this can be applied to anything that can travel through a tunnel). A similar structure can be used with cars and other vehicles, even if they are not as large as trains, to reduce energy costs. It can also increase the reliability of autonomous driving. A car or other vehicle can be connected to a cart or similar platform, with the weight of the car mainly supported by a sled, reducing rolling resistance. This cart or similar vehicle can be equipped with a motor that comes into contact with the road surface to transmit power, or the power of the car's engine or motor can be connected from the car's tires, engine, or motor to the power section of the cart or similar vehicle when the car is mounted on the cart, or the cart can be equipped with a device that transmits the rotational force of the car's wheels to the road surface as needed. Furthermore, even if an existing vehicle is not used, for example, if it is a four-wheeled vehicle, two more wheels can be attached to the center of the vehicle body, and this part will not come into contact with the ground during normal driving, but can come into contact with the ground if the angle is changed using hydraulics, etc., by using the four wheels to mount on a cart, etc., and the remaining two wheels can be brought into contact with the ground as needed using hydraulics, etc., or the cart can be given the function of a hydraulic jack, so that after the cart is mounted on the cart, the height of the car's tires can be changed using hydraulics, etc., to prevent contact with the ground, etc. There are several methods, such as attaching a device to the side of the tires of a car, etc., and connecting it to the tires, etc., so that their rotation does not come into contact with the road surface on the cart, etc., and converting the energy of the car's engine, motor, etc. into driving energy, etc., or attaching a roller part device to a cart, etc., which rotates in response to the rotation of the tires by rotating the engine, etc., without changing the position of the car passing through inspection, and connecting it to wheels with a mechanism that converts the rotational energy of the roller part so that the wheels of the cart do not come into contact with the road surface. To prevent the road surface, which transmits the driving energy, from freezing, water stored 5 meters underground and heated to about 15 degrees by geothermal heat is piped to the vicinity of the road surface. The water is then collected by a motor pump and collected in a tank so that it can be circulated.For emergency stops, stakes can be installed at the rear of the bogie, and if necessary, they can be lowered into the road surface to quickly stop the train. Even when using technologies such as linear motor cars to obtain lateral energy, cooling a portion of the magnetic field on the linear motor car's tracks and covering it with ice, and then attaching a sled, can save the vertical levitation force and concentrate most of the electrical energy on lateral energy, making it efficient. By adjusting the direction of the magnetic energy used to levitate the linear motor car and the energy used to accelerate in the direction of travel, electrical energy can be saved as much as possible. A sled and the above-mentioned powered wheels can also be attached to the linear motor car. A tunnel can be created in a near-vacuum state to eliminate wind loss and reduce noise, etc. The magnetic energy transmission part of the linear motor car and the sled device can also be installed separately. To cool the area where the sled comes into contact, efficient temperature control could be achieved by installing elongated heat-absorbing plates from a freezer, using dedicated heat-absorbing devices, or by using large compressors and underground water at a constant temperature. The waste heat from compressors could also be used to power a Stirling engine. Installing the compressor in a space where water drawn from 5 meters underground is circulated using pipes could be used to address heat issues. Even in existing roads, to prevent freezing and lower road surface temperatures in summer, water stored in tanks installed 5 meters underground beneath roads and walkways could be circulated using pipes to prevent the road surface from freezing or overheating. Pipes could also be used to circulate circulating water around the sled, improving cooling efficiency in summer. Plastic bottles could be used to create a futon-sized space (the size could be larger or smaller, and the size can be adjusted) that would maintain a cool temperature in summer and above freezing in winter. Water from a tank installed about 5 meters underground is passed through pipes into plastic bottles, etc., and the plastic bottles are connected so that the water circulates and returns to the tank.Water can be pumped using motors or installed underground in high mountains. Large underground tanks linked to large-scale facilities such as water purification plants can keep water at a temperature of nearly 15°C even in summer, allowing water pressure to be circulated and costs reduced. Roofs or covers can be installed at heights higher than vehicle height to provide protection from rain and sun. They can be opened and closed automatically by motors when vehicles pass through. For transporting objects, such as trains, the wheels of trains are replaced with sleds. Instead of tracks, a space wide enough for the sleds to pass through can be created, and water or other materials placed in that space can be cooled and frozen using electricity, reducing friction and minimizing energy loss. Wheels can be placed in contact with the gaps between rails and used during acceleration and deceleration. These wheels can also be retracted into the vehicle body using electricity to prevent contact with the ground when the vehicle gains speed, reducing resistance. The sleds can slide on frozen roads but have a protruding rail structure to prevent them from sliding sideways off the rails. To reduce impacts on curves, sleds can be fitted with tires that contact the rails. The track can be designed to slope slightly downward, allowing for acceleration through gravitational energy. While a track can be designed without elevation changes, even in cases where construction costs dictate an uphill track, sleds reduce friction, allowing for inertial energy to be used to move objects to higher ground. Even on a slight downward slope, the resistance at the contact points of the vehicle body is extremely low, allowing vehicles to rapidly accelerate even with only a small amount of energy provided by the contacting tires. The same is true for linear motor cars, which do not have contact with the ground. Air resistance can also be prevented by creating as much of a vacuum as possible inside the tube or tunnel surrounding the vehicle. Possible methods include opening hatches on the vehicle when it arrives at a station, creating a connecting passageway to the outside, or installing partition hatches or other doors that open and close vertically within the tunnel, allowing air to enter and exit sections of the station. When rainwater or the like enters into the structure on the lane which is cooled and kept at a temperature where the liquid or the like in the contact part has little resistance, a hollow hole is provided at the end of the lane so that the rainwater or the like can quickly escape, and the structure on the passage is made so that the rainwater or the like can flow out.A roof can be added to the top to prevent rainwater from entering and the structure can be completely shielded from the surrounding area.
