[0001] A gasoline engine, for example, is known as an energy conversion device. Detailed Description of the Invention

[0002] A gasoline engine, for example, is known as an energy conversion device. The present invention relates to an energy conversion device that converts primary energy into secondary energy.

[0003] However, conventional systems of this type emit carbon dioxide and are expensive to produce gasoline.

[0004] The present invention is intended to solve the above problems, and has an object to provide an energy conversion device capable of efficiently generating and converting primary energy into secondary energy.

[0005] An energy conversion device according to one embodiment of the present invention is characterized in comprising a liquid tank in which a liquid is stored, a plurality of gas receiving sections arranged vertically within the liquid tank and capable of rotating or moving up and down freely, a nozzle that sprays compressed gas from below the gas receiving section located at a lower part within the liquid tank, a gas cylinder that stores the compressed gas as a primary energy source and sends the compressed gas to the nozzle, an output means that outputs, as secondary energy to the outside of the liquid tank, kinetic energy of rotation or upward movement generated in the gas receiving section due to buoyancy generated when the gas receiving section receives the compressed gas sprayed out from the nozzle, and a recovery device that returns gas from the liquid tank to the gas cylinder.

[0006] With this configuration, compressed gas is sprayed into a liquid tank in which liquid is stored as a primary energy source, and the resulting movement energy due to buoyancy is converted into secondary energy. The gas is then recovered from the liquid tank and stored in a gas cylinder for reuse, making it possible to generate and convert energy efficiently.

[0008] With this configuration, inertial motion can be achieved by gliding on ice with little resistance, thereby improving the energy efficiency of traveling.

[0009] In addition, an energy utilization device according to one embodiment of the present invention is an energy utilization device that utilizes the energy of constant-temperature groundwater, and comprises: an underground tank that is buried in a specified underground area where a specified constant-temperature groundwater can be obtained and stores the constant-temperature groundwater; a structure formed by connecting and communicating with each other a plurality of hollow tubes made of an optically transparent material to form a hollow portion inside; a pipe and a circulation pump that circulate the constant-temperature groundwater 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 hollow portion formed by the structure, wherein the hollow portion is used as an air-conditioning space or a space for installing energy exchange equipment.

[0010] With this configuration, the energy of the constant temperature groundwater can be effectively utilized.

[0012] With this configuration, the energy of the constant temperature groundwater can be effectively utilized.

[0013] Furthermore, an energy utilization device according to yet another aspect of the present invention is an energy utilization device that utilizes sunlight energy, and includes a structure formed by connecting and communicating a plurality of hollow tubes made of a light-transmitting material to form a hollow portion therein, a pipe and a circulation pump for circulating water or hot water through the hollow tubes of the structure, and a fan for blowing air from one opening to the other opening into the hollow portion formed by the structure, the structure being installed in a location where it can receive sunlight, and seawater is passed through the bottom side of the hollow portion when viewed from above, and air is passed over the upper surface of the seawater by the fan to promote evaporation of the seawater and obtain salt.

[0014] With this configuration, sunlight energy can be effectively utilized.

[0015] Furthermore, an energy utilization device according to yet another aspect of the present invention is an energy utilization device that uses compressed air for air conditioning, and is characterized in that it comprises an air compressor powered by natural energy, and a tank buried underground for storing the air compressed by the air compressor, and the compressed air stored in the tank and temperature-controlled is sent through a pipe to an air-conditioned space.

[0016] According to such a configuration, natural energy can be effectively utilized, and the energy can be stored in the form of compressed air.

[0017] Furthermore, an energy utilization device according to yet another aspect of the present invention is an energy utilization device that generates electricity by utilizing natural energy, characterized in that it comprises a wall structure installed on a coast that simulates a ria coast where the force of ocean waves causes seawater to rise to a position higher than the sea level, a tank for introducing and storing the risen seawater through the wall structure, and a hydroelectric generator or an air compression compressor that generates electricity by utilizing the potential energy of the seawater stored in the tank.

[0018] With this configuration, the kinetic energy of seawater can be effectively utilized.

[0019] The following is an explanation of the form for implementing the invention.

[0020] (Energy conversion device) An energy conversion device according to an 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. This energy conversion device 1 is a device that ejects compressed gas as a primary energy source into the liquid tank 11 in which a liquid 10 is stored, 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 usually used in a sealed state. The liquid tank 11 stores the liquid 10. The liquid 10 is preferably water, but is not limited to water and may be any liquid. The size of the liquid tank 1 is, for example, 2 to 3 m, but is not limited to this. Inside the liquid tank 11, a power mechanism 31 is installed that generates a 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 hung, and the gear 31b that rotates due to the movement of the belt 31a. The upper gear 31b is submerged in the liquid 10 in FIG. 1, but its upper part may be above the liquid surface, and for example, nearly the upper half of the gear 31b may be above the liquid surface. The amount of gas to be discharged 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, such as the resistance that the liquid 10 exerts on the gas receiving portion 12.

[0022] The gas receiving parts 12 are arranged in a ring shape on the belt 31a, and thus a plurality of gas receiving parts 12 are provided in the vertical direction inside the liquid tank 11. The gas receiving parts 12 are movable up and down in conjunction with the movement of the belt 31a, and rotate at the upper and lower positions, so that the gas receiving parts 12 perform an orbital motion between the upper and lower positions as a whole. In this embodiment shown in Fig. 1, the belt 31a and the gear 31b rotate to the right, i.e., clockwise.

[0023] The nozzle 13 ejects compressed gas from below the gas receiving portion 12 located at the bottom in the liquid tank 11. The compressed gas is captured by the gas receiving portion 12 and gives buoyancy to the gas receiving portion 12. The gas receiving portion 12 receives buoyancy from the liquid 10, but when moving upward, it receives a larger buoyancy due to receiving the compressed gas ejected from the nozzle 13 than when moving downward. Although only one nozzle 13 is shown in FIG. 1, the number of nozzles 13 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 to eject gas from a wide area into the gas receiving portion 12.

[0024] 2(a) and (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 the belt 31a to move in a circular motion 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 ejects compressed gas from nozzle 13 via valve 14a, which is controlled to open and close. Valve 14a is controlled to open only when gas receiver 12 reaches a predetermined position. As a result, the compressed gas is efficiently captured in gas receiver 12, reducing consumption of compressed gas, and also reducing the mixing of air bubbles into liquid 10, thereby maintaining a high density of liquid 10, 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. The power source 50 is preferably natural energy, such as wind power, geothermal energy, hydraulic power, tidal power, or wave power, in order to suppress the generation of greenhouse gases.

[0027] The compressed gas generated by the compressed gas generator 5 is a gas with increased pressure so that the gas can be supplied from the nozzle 13 to the gas receiving part 12 against the water pressure of the liquid 10 in the tank 11. The gas supplied to the gas receiving part 12 is supplied in order to provide buoyancy to the gas receiving part 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 for converting the kinetic energy due to buoyancy into rotational energy of a rotating shaft 31c of a gear 31b, and a power generation device 32 for converting the rotational energy of the rotating shaft 31c into electrical energy as secondary energy.

[0029] The recovery device 4 is a device that returns the 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 remains. The recovery device 4 sends the gas remaining in the gas chamber 15 to the gas cylinder 14 via the compressed gas generator 5. The gas in the gas chamber 15 is the gas generated from the nozzle 13, the vapor of the liquid 10, etc.

[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 having a check valve function. The three-way valve 41 has a function of 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, in the case where 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 of this device, i.e., compressed gas, will be described as air, but is not limited to air. The liquid 10 will be described as water. Water is poured into the liquid tank 11 in which the power mechanism 31 is installed, piping such as the gas cylinder 14 is connected to the nozzle 13, 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. While adjusting the gas pressure in the gas chamber 15 with the three-way valve 41, 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 upward 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 belt 31a gradually starts 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 belt 31a reaches a steady state.

[0034] In a steady state of the rotation of the belt 31a, gas is released continuously from the gas receiving section 12 which rotates together with the belt 31a which is in contact with the upper gear 31b. The gas receiving section 12 which has released the gas moves downward with the movable wings 12a which can be opened and closed closed. When the gas receiving section 12 which rotates together with the belt 31a which is in contact with the lower gear 31b comes above the nozzle 13, the movable wings 12a which can be opened and closed open open, and receives the gas from the nozzle 13.

[0035] The rotating belt 31a converts the kinetic energy from the gas receiving part 12, which rises due to buoyancy, into the rotational kinetic energy of the gear 31b. The rotation of the gear 31b rotates the rotating shaft 31c, and the rotational energy becomes electrical energy generated by the power generation device 31 and is taken out to the outside. Of course, this energy can also be used directly to move 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 have the following relationship when the energy conversion device 1 is operating in a steady state. This formula shows the condition 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 discharge pipe extremely small when discharging 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 the pipe and the water pressure in the tank is only enough to turn the butane into gas, it will vaporize efficiently.

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

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

[0039] According to such an energy conversion device 1, compressed gas as a primary energy source is ejected into the liquid tank 11 in which the liquid 10 is stored, the resulting movement energy due to buoyancy is converted into secondary energy, and the gas is recovered from the liquid tank 11 into the gas cylinder 14 for reuse. Therefore, energy can be efficiently generated and converted. Regarding the reuse of gas, when a special gas other than air is used as the working gas, i.e., the compressed gas, the special gas can be recovered and reused. In addition, 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 pressure energy of the gas, 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 grounded. 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 further shaft 3f, which are successively 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 lateral outside of the liquid tank 11 so as to surround the coupler 3c and the vertical shaft 3d. The water seal tank 11A has a communication opening 11w that communicates with the inside of the liquid tank 11 and an upper opening 11k that opens upward. The water seal tank 11A contains liquid 10, and the liquid level is opened 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 is different from each other 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 taken out 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 manner.

[0044] The transmission device 30 extracts the energy converted and generated in the liquid tank 11 as mechanical energy via these couplers 3a, 3c, 3e and shafts 3b, 3d, 3f to the outside of the energy conversion device 1 and transmits it to an external operating device 33.

[0045] The operating device 33 is a water pump, and is configured with a chain 33c hung on upper and lower sprockets 33a and 33b, and multiple buckets 33d. The rotational energy extracted from the energy conversion device 1 is transmitted as rotational energy to the upper sprocket 33a via the 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, so that the mechanical energy can be used as it is as energy for the mechanical operation of the operating device 33.

[0047] Next, referring to Figs. 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 Fig. 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 valve 14. Also, gas in the gas chamber 15 of each liquid tank 11 is collected in a sub-cylinder 40 via a three-way valve 41. The liquid tanks 11 arranged in parallel are not limited to those having 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 arranged 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 from the side closer to the gas cylinder 14 via a valve 14a. Gas is delivered from the gas chamber 15 of the first liquid tank 11 to the nozzle 13 of the second liquid tank 11 via a three-way valve 41. Gas is delivered from the gas chamber 15 of the second liquid tank 11 to the nozzle 13 of the third liquid tank 11 via a three-way valve 41. Then, gas is collected from the gas chamber 15 of the third liquid tank 11 in the 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 Fig. 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 sent to the nozzle 13 of the upper liquid tank 11 via a three-way valve 41. The piping for introducing the gas is arranged up to the upper level of the upper liquid tank 11, and then pulled back to 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 capable of adjusting the internal pressure.

[0053] A pipe for generating compressed gas is connected to the lower side wall of the cylinder 51 through an opening. 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 through a water seal structure. A chain is attached to the lower surface of the pressurizing piston 52, and the chain is fixed to a winch 53 located above the water seal tank 11A through the water seal structure so as 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 the compressed gas is sent to the gas cylinder 14.

[0055] 7(b), in the intake process, the internal pressure of the life-ring-shaped seal 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 compressing the gas by pushing the pressure piston 52 downward are not limited to those using the hoist 53, and various methods can be used. For example, instead of the water-sealed structure and the hoist 53, a configuration in which hydraulic 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 float-shaped sealing material 52b, the internal pressure of which can be adjusted.

[0057] Next, referring to FIG. 8, another example of the compressed gas generator 5 will be described. This compressed gas generator 5 generates the compressed gas by heating solid dry ice with the heat of combustion of a mixed gas containing hydrogen and oxygen to turn it into a gas, thereby expanding the volume. The generated compressed gas is delivered to the gas cylinder 14. In general, the working gas may be a gas that generates buoyancy when delivered from the nozzle 13. For example, the working gas may be in a liquid or solid state, not a gas, during the period from the gas chamber 15 to the gas cylinder 14. After the recovery device 4, a working gas that is converted into a solid or liquid by being made into dry ice or liquefied gas may be used. For example, a substance that is 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, that is, on the sub-cylinder 40 side, there is a valve 42 having a check valve function. In addition, on the downstream side of the heat exchanger 54, that is, on the gas cylinder 14 side, a three-way valve 51a for adjusting the gas pressure, etc. is provided as necessary.

[0059] In this compressed gas generator 5, a heat medium 54a that becomes high temperature is sealed in the housing of a heat exchanger 54. A pipe that guides the working gas that circulates inside the energy conversion device 1 to operate the energy conversion device 1, that is, the gas that becomes compressed gas, is surrounded by the heat medium 54a inside the heat exchanger 54. The working gas inside the pipe is gasified into a high pressure gas by receiving heat from the heat medium 54a, and becomes a compressed gas. The working gas does not need to be in a gaseous state at all times while circulating inside 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 hot 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 heat (such as heat from magma), or heat from a hot spring.

[0061] The substance that becomes the working gas may be arbitrarily selected and used 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 freon may be used as the working gas. Furthermore, ammonia water, etc. may be used as the liquid 10 in addition to water.

[0062] Next, a circulation process of the working gas in one embodiment of the energy conversion device 1 will be described with reference to Fig. 10. 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 device main body 11R of the energy conversion device via the gas cylinder 14, and collected from the device main body 11R into the sub-cylinder 40 and returned to the compressed gas generator 5. The device main body 11R is a general 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 assumes that the working gas is freon, which is used as a refrigerant in a refrigerator or 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-retaining material when cooled by expanding and releasing 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 by being made into a high-pressure gas.

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

[0065] The carburetor 18 expands the working gas through an expansion valve and the like to further cool it. The cooled working gas can absorb heat from the surroundings, and its heat absorption capacity is used to build air conditioning systems, etc. The working gas that has passed through the heat exchanger 17 and the carburetor 18 becomes compressed gas with an appropriate pressure adjustment, 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 inputted into the working gas in advance in the compressor 16, and 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 parts 12 provided around the outer periphery of a rotor that rotates around one axis. The gas receiving parts 12 have the structure shown in Fig. 2(a)(b).

[0068] In this embodiment, two power mechanisms 31A that rotate clockwise are installed in the liquid tank 11. A valve 14a and a nozzle 13 are provided for each of the power mechanisms 31A. The rotational energy of the power mechanisms 31A is converted into electrical energy by a power generation device 32.

[0069] (Vehicle body movement device) Next, a vehicle body moving device according to an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 12(a) and (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 liquid to guide the sleds 22 sliding on the ice, and a drive unit for running the vehicle body 21.

[0070] The rail 23 includes a housing 23a having a concave cross section with a groove formed in the longitudinal direction and fixed to the road surface 20, and a refrigerant pipe 23b arranged inside the groove through which a refrigerant passes. Water is poured into the groove of the housing 23a and cooled by the refrigerant pipe 23b to form ice 2b. The surface of the ice 2b becomes the ice surface 2a when the sled 22 slides on the ice. The rail 23 may be provided with a cover to prevent rain and the like from entering the inside when the sled 22 is not sliding on the ice, and may also be provided with a drain hole to drain water present on the ice surface 2a. This cover and the housing 23a of the rail 23 are cooled by circulating underground tank water through a pipe.

[0071] Guide wheels 21a are provided adjacent 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 encase and surround the sled 22 so as to prevent the sled 22 from deviating from the rail 23.

[0072] The driving 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 freely 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 sleds on the ice surface 2a using the sled 22 (Fig. 12). When driven, the wheels 24 come into contact with the road surface 20 to cause the vehicle body 21 to wheel-travel (Fig. 13).

[0073] As shown in Fig. 13(a), two wheels 24 may be arranged in the front-rear direction between the front and rear sleds 22, or as shown in Fig. 13(b), one wheel may be arranged in the front-rear direction. The arrangement and number of wheels 24 can be set arbitrarily according to the respective roles of sled running and wheel running. For example, when the sled 22 is run 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. Also, 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 device that does not have wheels 24. For example, a jet propulsion device or a propeller propulsion device may be mounted on the car body 21 and used as the drive device. A linear motor may also be used as the drive device. In this case, the track that forms the magnetic field of the linear motor may be covered with an ice surface by freezing a liquid. Also, a linear motor may be combined with the wheels 24 that obtain driving force from an engine or motor mounted on the car body 21 to form a drive device.

[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 engagement 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 a structure and function as a shock absorber. In addition, the pairs of the cylinder 25a and the piston 25b are arranged at predetermined intervals along the rail 23. The pairs of the cylinder 25a and the piston 25b may be arranged at predetermined intervals along the entire line of the rail 23, or may be arranged at predetermined intervals within a predetermined range.

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

[0078] The braking device 25 is provided with a plurality of safety valves 25d for releasing pressure in the cylinder 25a to prevent breakdown. The safety valves 25d are set to function in stages according to the pressure stages. If the vehicle body 21 cannot be stopped within the movable range of the pistons 25a, the lock between the locking portion 26c and the engaging portion 21b is automatically released, and the engaging portion 21b is locked to the locking portion 26c of the next set of cylinder 25a and piston 25b in the traveling direction, and the braking operation is performed by that set. The braking device 25 is set and arranged according to a predetermined rule of 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 area where a specific constant-temperature groundwater can be obtained, and stores the constant-temperature groundwater. The underground tank T is placed, for example, near an underground water 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 ground by a pump P2.

[0081] The structure 60 has a cavity 61 formed therein by connecting a plurality of hollow tubes 6a formed of a light-transmitting material in communication with each other. The cavity 61 is used as an air-conditioning space or an energy exchange device installation space. The structure 60 may be installed on the ground when used in the presence of sunlight, for example, or may be installed underground in other cases. If installed underground, it is easy to use the structure 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 opening a portion of both ends.

[0082] The pipe 62 and the circulation pump P3 are used to circulate the 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 necessary 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 keeps the inside of the cavity 61 at a constant temperature. The fan 63 generates an air flow in the sealed cavity 61 formed by the structure 60. This air blowing eliminates stagnation of air within the cavity 61. The structure 60 may be provided with external piping from one end to the other end to form a closed wind passage, and the fan 63 may generate a unidirectional wind flow within the structure 60.

[0083] As shown in FIG. 16, the hollow portion 61 is preferably used as an installation space for a solar panel 64. The solar panel 64 is an energy exchange device that converts solar energy into electrical energy. The solar panel 64 is in the hollow portion 61 whose four sides are kept at the temperature of groundwater, and air is blown 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 hollow portion 61 of the structure 60 can be an appropriate shape that can optimize and improve the efficiency of temperature control of the contents to be stored therein, depending on the contents to be stored therein. For example, in the case of the solar panel 64 of FIG. 16, the hollow portion 61 may be a sealed hollow portion surrounded by a wall formed by a hollow tube 6a close to the outer peripheral surface including the front and back surfaces of the panel so that the panel can be stored in the smallest space, or a partially open non-sealed hollow portion 61 may be used.

[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 a plurality of underground tanks T (three in the illustrated example) and a mixer 6mx that mixes groundwater from each tank. The underground tanks T are buried individually at a plurality of depths underground so that groundwater at different temperatures t1, t2, t3 can be obtained. The mixer 6mx mixes the groundwater at different temperatures t1, t2, t3 obtained from the plurality of underground tanks T, and delivers groundwater at a constant temperature adjusted to a predetermined temperature t0 regardless of the season. Even if the temperature of each groundwater varies seasonally, the predetermined temperature can be maintained by changing the mixing ratio taking into account the temperature difference between each groundwater.

[0085] Next, referring to FIG. 18, an energy utilization device 6A according to another embodiment of the present invention will be described. The energy utilization device 6A is a device that utilizes constant-temperature underground energy, and includes a hollow pipe 65 provided between the ground surface and a predetermined depth underground at a predetermined constant temperature, and a fan 66 that sends air from the ground surface side to the hollow pipe 65. The air sent to the hollow pipe 65 by the fan 66 and cooled or heated by heat exchange through heat emission or absorption at a predetermined depth underground can be used for air conditioning on the ground surface side. In order to facilitate heat exchange underground, the surface area of ​​the pipe may be increased by providing multiple fins on the pipe or by making the pipe into multiple branched pipes at the heat exchange location. 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, and the temperature, which is cold in summer and warm in winter, is transported to the desired location on the ground using pipes, etc., and constructed by connecting plastic bottles, for example. It can also be made to flow through a structure. If a space is provided around the path along which the liquid flows, the air there will be closer to the temperature of the surrounding liquid. The path of the space can be configured to be as long and narrow as possible so that heat exchange is carried out efficiently. (Figure R1)

[0086] Next, an energy utilization device 6B according to yet another embodiment of the present invention will be described with reference to Fig. 19. The energy utilization device 6B is a device that utilizes sunlight energy, and includes a structure 60 having a cavity 61 formed therein by communicating and connecting a plurality of hollow tubes 6a formed of a light-transmitting material, 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 passed over the upper surface of 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 still another embodiment of the present invention will be described with reference to Fig. 20. The energy utilization device 6C is an energy utilization device 6C that utilizes compressed air for air conditioning, and includes an air compressor 68 powered by natural energy, and a tank Ta buried underground for storing the air compressed by the air compressor 68. In this example, a solar panel 64 is provided to use sunlight as the natural energy.

[0089] Compressed air stored in a tank Ta and regulated 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 still another embodiment of the present invention will be described with reference to Fig. 21. The energy utilization device 7 generates power by utilizing natural energy, and includes a wall structure 71 installed on a coast that simulates a ria coast where seawater rises up to a position higher than the sea level due to the force of ocean waves, a tank 72 that introduces and stores the risen seawater 70 by the wall structure 71, and a hydroelectric generator 74 that generates power by utilizing the potential energy of the seawater 70 stored in the tank 72.

[0091] Seawater waves crashing on the shore have their path 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 starts to flow toward a hydroelectric generator 74 through 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, it is possible to generate compressed air using potential energy and store it in a tank instead of generating electricity, thereby storing the potential energy as pressure energy.

[0093] 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, a vehicle that transports objects, such as a train's wheels replaced by a sled, etc. Instead of rail tracks, a space just wide enough for a sled to pass through is provided, and water or other items are placed there, and electricity or other means are used to cool and freeze the sled, reducing friction and minimizing energy loss. Wheels or other items are placed in contact with the gaps between the rails and are used when accelerating or decelerating. These wheels or other items can also be retracted into the car body using electricity or other means so that they do not come into contact with the ground when the train gains speed, reducing resistance. The sled slides on the frozen road surface, but has a rail structure with a protruding shape to prevent it from going off the rails sideways. Tires or other items that come into contact with the side of the rails can be attached to the sled to reduce shock when going around curves. The route is designed to go down gradually, and the acceleration force is generated by gravity energy. The route can be designed without any elevation difference, but even if the cost of construction is calculated and an uphill route is created, friction is reduced by sleds, so the inertial energy can be used as the source of energy to move objects to higher ground. Even with a slight downward slope, the resistance of the contact parts of the car body is extremely small, so the vehicle can accelerate rapidly even with only a small amount of energy provided by the tires that are in contact. The same can be said for linear motor cars and other vehicles that are not in contact with the ground. In addition, air resistance can be prevented by creating as much of a vacuum as possible inside the tube or tunnel that surrounds the vehicle. Possible methods include opening the hatch on the vehicle when it arrives at the station and creating a connecting passage with the outside, or installing a hatch or other partition that opens and closes at the top and bottom inside the tunnel, and partially letting air in at the station section so that passengers can enter and exit there. If rainwater or the like gets into the structures on the lane, which are cooled and kept at a temperature where the liquid in contact with them has little resistance, a hollow hole is provided at the end of the lane so that it can quickly drain out, and the structure on the passage allows the rainwater or the like to flow out. A roof is attached to the top to prevent rainwater or to make the structure capable of shielding everything around. When shielding, it is covered with a transparent, light-transmitting material or strong plastic, or a structure made of connected PET bottles (or other specialized ones) is used to make a PET bottle where juice was originally contained, and water or the like is pumped from an underground tank installed in a place where the temperature is kept at about 15 degrees throughout the year about 5 meters underground using a pump (if it is underground in a mountain area, there is natural energy that falls due to gravity pressure) and circulated, so that the space where cars pass through is close to 15 degrees Celsius, and by adjusting the flow rate of the liquid, the cost of air conditioning can be saved. When the pressure is reduced to make the space where cars pass through close to a vacuum in order to reduce air resistance, pressure-resistant reinforced plastic, glass, etc. can be installed on the outer periphery of the space where cars pass through to reinforce it. When circulating water or other liquids using a pump, liquids such as water will not suddenly boil even when exposed to sunlight from outside, so the pump does not have to be operated frequently, and energy costs are low.When obtaining energy from solar panels, etc., solar panels, etc. are installed on the roof of this facility, or in an empty space on the side or lane. In order to cool the 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 the underground tank is flowed there to control the temperature of the solar panels, or the solar panels are made waterproof and airtight, and the panels are attached to a tub or the like that contains shallow water, and water of about 15°C installed about 5 meters underground is flowed there and collected in the underground tank. If the position is such that natural groundwater flows naturally, it is acceptable to let the water flow freely, and the temperature of the panels is controlled. For example, a structure is constructed by cutting out the drinking spout of a plastic bottle, etc., and gluing multiple rectangular cubes together to fill the space with water from the underground tank. A structure filled with water, etc., and hollow inside is created using a material such as a plastic bottle that transmits light, etc. but does not transmit water, etc. Then, in the hollow part, you can put things like solar panels or things you want to control the temperature. By installing a similar device in solar panels installed in your home, you can increase the amount of electricity they generate. If the solar panels get too hot, the amount of electricity they generate will decrease. Also, to efficiently air-condition the space, water at about 15 degrees from the underground tank mentioned above will be 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. Inside the underground tank, water that has been cooled to about 15°C by the ground temperature is placed in a pipe about 5 cm long and wide (this is only a rough guideline and can be changed freely), and a structure with a passageway for the water to flow around it is set up, 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. When the air moves through the pipe with the force of the fan, it exchanges heat with the surrounding water (for example, thin materials such as plastic bottles conduct heat easily), and in summer it gradually cools down. If the length of the pipe is made long enough, the temperature at the outlet of the pipe will be close to the temperature of the water from the underground tank. In summer it will be cold, and if the air is lower than about 15°C it will be warm. For example, a structure can be made by connecting plastic bottles. Fans such as electric fans consume little electricity, so they are energy-efficient. The pipe does not have to be straight, so it can be curved to increase the distance. It is also possible to pass a thinner pipe through the pipe so that the water can circulate there as well, making it easier to exchange heat when exposed to wind. It is also possible to increase the contact area between the flowing air and the water at a temperature of around 15°C by passing a metal rod with high thermal conductivity between the pipe and the passage through which the circulating water flows. It is also possible to increase the heat exchange efficiency by installing a fan not only at the entrance of the pipe but also at the other exit or in the middle. This device can be installed indoors, but it can also be installed in places with a constant ground temperature, such as about 5 meters underground. Air is pumped in and out using a pipe. If air is pumped into the pipe through a pipe at a depth of about 5 meters underground where the ground temperature is about 15°C, in the summer, the air sucked in above ground will travel underground and when it leaves the pipe outlet, its temperature will be close to the ground temperature of 15°C, and this is the same regardless of the season, even in winter. Water flows on all four sides or in a specific part of the pipe, but in the case of a two-tiered structure, the water will be maintained by gravity even if the ceiling part of the lower part is not sealed, so there are cases where it is not necessary to install a ceiling part, and the water will come into direct contact with the air, improving the heat exchange efficiency. If the ground temperature around the pipes is around 15°C, the original air temperature will approach 15°C. Compressed air is used when hot spring water or water artificially heated in a boiler is used for air conditioning in homes and facilities.First, hot water is poured into a space made of PET bottles, etc., and in the above method, the temperature of the underground is about 15 degrees, and heat is exchanged to bring the temperature of the air, etc. closer to 15 degrees. However, if you put hot water instead of 15 degrees, the temperature will be that temperature. Then, in order to keep it warm when sending it, you put it in a pipe made of connected PET bottles, etc., and send it in a compressed state (or just a little ventilation, depending on the situation) in the space enclosed by it. The above-mentioned space for sending hot air, etc. can be installed underground or above ground, but if the ground is very cold, etc., considering the cost of digging underground, you can use an insulation system using water, etc. in a tank about 5 meters underground at about 15 degrees. Since the depth of underground tanks, etc. varies depending on the season according to the depth, multiple tanks can be prepared and water, etc. can be mixed. If necessary, the efficiency can be increased by covering the outer periphery of the device that sends the air, etc. made from this PET bottle with insulation material (such as styrofoam, which has an insulating effect). Cold air, etc. can also be sent. Plastic bottles are connected together to create a rectangular space, and then plastic bottles are connected together to create a structure. Then, as described above, liquids can be poured in, and items that need to be dried or humidified 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 it is possible to leave some gaps so that warm air can be blown in. For example, when evaporating seawater to extract salt, A space filled with seawater, a space above it where hot air can flow, and below that, a plate-shaped passage (which can be slightly inclined) made from PET bottles, etc., is made, and a space above that where water can flow is made. The outer periphery can be surrounded by PET bottles, etc., and the entire inside can be pressurized with a compressor, etc. The evaporation of seawater is accelerated by using the power of sunlight or by flowing hot water, and further accelerated by sending hot air, etc. When the humidity becomes high, the inside pressurized by the compressor is returned to normal pressure, and cold water from an underground tank, etc. is flowed through the pipe. When the humidity decreases and the temperature nearby is cooled, water droplets that come out of the air all at once flow through the installed plate and move to the lowest position. By adopting this structure, the speed at which seawater evaporates can be increased. The outer periphery constructed from PET bottles, etc. can be covered with transparent film, plastic, etc. as necessary to withstand pressure. When the air inside this device is released to the outside, a filter to prevent salt damage can be installed on the outside air intake or exhaust fan, etc. 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 fine particles in the first place, so it was simply installed just in case. Hatches are installed in areas that can ventilate so that the device can withstand pressure being applied inside. 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 spaces that require sunlight, such as solar panels, to prevent the solar panels from heating up while obtaining salt. For the lower part, a base is made out of transparent materials such as plastic bottles, and the angle of the device can be adjusted depending on the angle at which the solar panels are installed. When raising fish, the space should be made into a loop structure so that the fish do not collide with the walls of the space filled with water by accelerating in a direction close to vertical. As shown above, a space is made using a plastic bottle or the like and water is poured into it. A lid can also be made from a plastic bottle or other material for the top. A pump can then be used to suck out the water inside and spray it out under pressure, or compressed air can be sent in one direction to give the water a fixed rotation. The width of the loop structure where the fish swim should be about 50 to 100 cm (this is just a guideline). Usually, electric compressors are used to compress air industrially, but the energy of hydraulic gears or the rotational energy of a windmill is used to power the compressor. A tank that stores compressed air is installed at a constant ground temperature about 5 meters underground, or the temperature is brought close to 15°C by blowing it into water in a tank installed 5 meters underground. By using natural energy such as hydraulic power as the power source for an air compressor and storing it in a cylinder installed underground, it can be taken out at any time like a battery and used to move the gears. When compressing air with a compressor, it can be cooled in an underground tank and compressed to adjust the humidity, or the air can be stored underground to lower the humidity. The temperature can also be lowered by placing a tank containing compressed air underground. Even if the tank is large, there is no problem with the installation location if it is underground. Using the above mechanism to adjust the temperature and humidity of compressed air and flow it from the facility to general households through underground pipes, etc., is highly efficient. Instead of storing electricity, it is stored as compressed air (which can be in gaseous or dry ice form). It is also possible to install a waterwheel-like structure next to a river. If the ocean waves are in a ria coast, tsunamis will surge up to high places, so such a structure is artificially created and the force of the ocean waves is used to bring seawater up to 10 meters or so higher than the coastline. The water is then stored and used to turn a hydroelectric turbine that uses gravity to generate electricity or to power an air compressor. By using the energy of ocean waves to obtain the potential energy of a large amount of seawater semi-permanently, it can be used to benefit human life. Using this method, compressed air can be stored in a cylinder or the like and the cylinder can be moved to a location 20 meters underground, or the cylinder can be fixed with a diameter of 20 meters. Then, prepare a tank filled with water, etc., installed underground. A rotating wheel or the like is installed there and compressed air is released from below, and the energy generated when it rises will cause the wheel to rotate. The deeper the tank, the more wheels etc. can be installed, and buoyancy will provide the energy to rotate the water wheels.The rotational energy of the waterwheel and wheels can be used to operate a compressor to create compressed air or to run a generator, which is very efficient. Compressed air (gas), dry ice, and gas (Oomasa gas, HHO, GAS, etc.) are placed at a deep point where water pressure is applied to a vertical tank filled with liquid water, etc., and heat is added from electricity or chemical reactions to ignite the 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 used to turn the waterwheel, etc. This energy is recovered and used to run a generator. In order to increase the efficiency of the waterwheel when it rotates, the blades of the waterwheel are made movable and can be opened and closed. In this way, when it is pushed by the gas, it opens and receives the kinetic energy, and it is possible to prevent the rotation speed from decreasing as much as possible when the blades of the waterwheel hit the liquid and create resistance. The blades open and close, but do not close completely, leaving them slightly open so that air can enter and push them apart, or plates can be attached to make it easier for air to gather in the blades of the tank's waterwheel. If a waterwheel of this shape is installed in a tunnel or other place where there is no energy for air or other gases to rise and water pressure is applied, the blades will open where they are pushed by the water flow and close when the water flow pressure weakens. In hydroelectric power generation at large dams, there are some with a head of 100 meters and hundreds of meters of pipes, but if the hydroelectric power generation propeller is only attached to the downstream part, the energy of the water flow cannot be fully recovered to turn the turbine of the generator, resulting in loss, so the head is about 10 meters and the energy is dispersed in a thinner pipe-like tunnel or tube, or a waterwheel or hydroelectric power generation propeller is installed in the section where there was only water flow until now. In this way, the potential energy of the water flow can be efficiently recovered. Furthermore, when compressed air, etc. is sprayed from deep within where water pressure is high, and a water wheel, etc. is turned by the force of the air rising upwards, if the water tank or tank is designed in such a way that the compressed gas, etc. is sprayed exactly at around 1 o'clock when the water wheel, etc. is rotating clockwise, the deceleration of the propeller, water wheel, etc. due to water pressure can be prevented.Compressed gas is also ejected from the 6 o'clock direction, etc., so the force of clockwise rotation is always continuous, and the energy of compressed air, gas, etc., and the force of buoyancy due to differences in density, etc., are converted into the rotational energy of a water wheel, etc. When the shaft of a water wheel, etc. is made hollow and compressed gas is injected into it, a catch is placed at the 1 o'clock or 6 o'clock position, and the hole in the shaft is caught by it, opening the door through which the gas is ejected. When the door reaches a position where it is not caught, it closes with the force of a spring, etc., or a structure can be used in which gas is passed through the hollow part of the shaft and the cover is covered with a cap made of metal, etc., so that when a specific part of the cap has a hole, gas can be ejected when the gas ejection port of the rotating shaft reaches a specific position, or a method can be considered in which the ejection of compressed gas is linked to the position of the water wheel, and a valve is controlled so that compressed gas is ejected only when the water wheel reaches a specific position. The shaft part that transmits the energy of the waterwheel, etc. can be extended horizontally to increase airtightness so that water does not leak out of the tank, etc., 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 the shaft that extends upward, and when 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, etc. Several waterwheels, etc. can be installed vertically, linked together. Various methods are possible, such as extending the tank deep underground or raising it above ground. The temperature of about 5 meters underground in mainland Japan is kept at about 15 degrees all year round. By using this natural law and grounding a tube-shaped tunnel there, it is possible to save energy required for cooling. Alternatively, when this structure is grounded on the ground and cooled, the outer periphery of the tube can be covered with liquid water, etc., and if the outer periphery of the tube is made of plastic, glass, or other light-transmitting material, the scenery can be seen from inside the vehicle. It is also possible to fill a similar tunnel with water, etc. and run a sealed ship inside, and by creating a vacuum inside the tunnel, the energy efficiency during travel can be increased (this can be applied to anything that can run inside a tunnel). By using a similar structure for cars, etc., not just large things like trains, energy costs can be reduced. It increases the reliability of automatic driving of cars. Cars, etc. are connected to carts, etc. installed on a similar platform, and the weight of the car, etc. is mainly supported by a sled, reducing rolling resistance, etc. There are various methods, such as incorporating a motor or the like in order to contact the road surface and transmit power, connecting the power of the engine or motor of an automobile or the like from the tires, engine, or motor of the automobile to the power unit of the automobile or the like while the automobile or the like is mounted on the automobile or the like, or equipping the automobile or the like with a device for transmitting the rotational force of the wheels of the automobile or the like to the road surface or the like as necessary. Also, even if an existing car or the like is not used, it is possible to attach two more wheels to the center of the body of a four-wheeled vehicle in advance, and have the structure so that the part does not come into contact with the ground during normal driving, but can come into contact with the ground by changing the angle or height by hydraulic pressure or the like, and use the four-wheel part to ride on the automobile or the like, and the remaining two wheels (rubber, iron, etc. wheels, etc.) can be brought into contact with the upper part of the cooling rail as necessary by hydraulic pressure or the like, or by giving the automobile or the like the function of a hydraulic jack to the automobile or the like so that the height of the automobile's tires can be changed after the automobile or the like has climbed onto the automobile or the like, and the automobile or the like can be raised or lowered by hydraulic pressure or the like to prevent it from coming into contact with the ground or the like. This bogie can be equipped with a motor to provide driving force when running, or part of the bogie can be powered to be pulled or pushed and connected to other bogies like a train, or powered bogies can be appropriately positioned to reduce installation costs.The movement of the trolley (unit) can be monitored by sensors, and cameras, etc. can be installed around the cooling lane so that the trolley can be controlled automatically without human intervention. Solar panels, etc. can be installed near the space where the cooling lane is installed, and electricity from the solar panels can be transmitted from the metal parts of the lane to the motors of the trolleys, etc., or non-contact power transmission can be used so that the lane and the electric 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 the tires of a car, etc., and connecting it to tires (which can be iron wheels, etc.) that can prevent the rotation from coming into contact with the road surface installed on the trolley, or the ice-free upper part of the cooling rail, etc., and converting the energy of the engine, motor, etc. of the car into driving energy, etc., or attaching a device to the trolley, etc. for the roller part that rotates according to the rotation of the tire by rotating the engine, etc. on the spot without changing the position of the car passing through during vehicle inspection, and connecting it to the wheels with a mechanism that can convert the rotational energy of the roller part so that the wheels of the trolley do not come into contact with the road surface. In order to prevent the road surface from freezing, water stored 5 meters underground at about 15 degrees Celsius due to geothermal heat is piped to the road surface, and the water is collected by a motor pump and collected in a tank so that it can be circulated. For emergency stops, piles are installed at the rear of the cart, and if necessary, they can be lowered to the road surface to stop it quickly. Even when using linear motor cars and other technologies to obtain energy in the direction of travel, if the magnetic field of the linear motor car's tracks is partially cooled and covered with ice, and a sled or other device is installed to reduce resistance during travel, the vertical levitation force can be saved and most of the electrical energy can be concentrated in the direction of travel, making it efficient. The levitation energy during travel and the energy accelerating in the direction of travel are adjusted to be as low as possible to save electrical energy by adjusting the direction of the magnetic energy applied, so that the levitation energy is kept low, and the balance between power consumption during travel and speed is maximized. Even if the car is not actually floating, the sled reduces resistance and allows it to run. A linear motor car may be equipped with a sled and the powered wheels.The inside of the tunnel is made close to a vacuum state, eliminating losses due to wind and reducing noise. The magnetic energy transfer part of the linear motor car and the sled device can be installed separately. To cool the part where the sled is in contact, a long and thin heat absorbing plate from a freezer can be installed there, or a dedicated heat absorbing device can be used, or efficient temperature control can be achieved by using a large compressor and water at a constant temperature underground. The exhaust heat from the compressor can be used to run a Stirling engine. The compressor can be installed in a space where water drawn from 5 meters underground is circulated around it using pipes, etc., to take measures against exhaust heat. In the current roads, water can be circulated in a tank installed 5 meters underground under the road or passageway to prevent freezing and to lower the temperature of the road surface in summer, and the road surface can be prevented from freezing or excessive heat can be prevented by circulating water 10 cm below the asphalt using pipes. The cooling efficiency can also be improved in summer by making it possible to flow circulating water around the sled part using pipes. Using plastic bottles, etc., create a space the size of a futon (it can be larger or smaller, the size can be changed) and keep the temperature inside the space cool in the summer and not freezing in the winter. Water from a tank installed about 5 meters underground is placed inside the plastic bottles through pipes, and the plastic bottles are connected so that the water circulates and returns to the tank. Water can be pumped using motors, installed underground on high mountains, or sent to each home using a large underground tank connected to a large facility such as a water purification plant, with a temperature of about 15°C even in the summer, allowing water to be pumped using only water pressure. A sealed cover can be placed on the top of the cooling rails (lanes), and water from the underground tank at about 15°C can be circulated there, reducing the cost of cooling towers. The top covers of the cooling rails and lanes are closed electrically in the summer, etc., to prevent heat from accumulating as much as possible, but they can be opened and closed automatically by a motor, etc., when a sensor detects the passage of vehicles, etc. When freezing liquids such as water inside a cooling lane, etc., compressed air (carbon dioxide) or gas can be sent through pipes passing through the liquid or ice, and cooled using the latent heat of vaporization. For example, a vehicle that transports objects, such as a train's wheels replaced by a sled, etc. Instead of rail tracks, a space just wide enough for a sled to pass through is provided, and water or other items are placed there and cooled and frozen using electricity or other means to reduce friction and minimize energy loss. Wheels or other items are placed in contact with the gaps between the rails and are used when accelerating or decelerating. These wheels or other items can also be retracted into the car body using electricity or other means so that they do not come into contact with the ground when gaining speed, reducing resistance. The sled slides on the frozen road surface, but has a rail structure with a protruding shape to prevent it from going off the rails. Tires or other items that come into contact with the side of the rails can be attached to the sled to reduce shock when going around curves, etc. The route is designed to go down gradually, and the acceleration force is generated by gravity energy. The route can be designed without any elevation difference, but even if the cost of construction is calculated and an uphill route is created, friction is reduced by sleds, so the inertial energy can be used as the source of energy to move objects to higher ground. Even with a slight downward slope, the resistance of the contact parts of the car body is extremely small, so the vehicle can accelerate rapidly even with only a small amount of energy provided by the tires that are in contact. The same can be said for linear motor cars and other vehicles that are not in contact with the ground. In addition, air resistance can be prevented by creating as much of a vacuum as possible inside the tube or tunnel that surrounds the vehicle. Possible methods include opening the hatch on the vehicle when it arrives at the station and creating a connecting passage with the outside, or installing a hatch or other partition that opens and closes at the top and bottom inside the tunnel, and partially letting air in at the station section so that passengers can enter and exit there. The temperature of about 5 meters underground in mainland Japan is kept at about 15 degrees all year round. By using this natural law and grounding a tube-shaped tunnel there, it is possible to save energy required for cooling. Alternatively, when this structure is grounded on the ground and cooled, the outer periphery of the tube can be covered with liquid water, etc., and if the outer periphery of the tube is made of plastic, glass, or other light-transmitting material, the scenery can be seen from inside the vehicle. It is also possible to fill a similar tunnel with water, etc. and run a sealed ship inside, and by creating a vacuum inside the tunnel, the energy efficiency during travel can be increased (this can be applied to anything that can run inside a tunnel).

Also, even if an existing car or the like is not used, it is possible to use a method in which, for a four-wheeled vehicle, two more wheels are attached to the center of the vehicle body in advance, and this part does not come into contact with the ground or the like during normal driving, but is structured so that it comes into contact with the ground if the angle is changed by hydraulic pressure or the like, and the four-wheeled part is used to ride up the dolly or the remaining two wheels are made to come into contact with the ground as necessary by hydraulic pressure or the like, or the dolly is given the function of a hydraulic jack, and after the automobile or the like rides up on the dolly, the height of the automobile's tires can be changed to prevent it from coming into contact with the ground or the like.There are several methods to convert the energy of the engine, motor, etc. of a car into driving energy, etc., by attaching a device to the side of the tires of a car, etc., and connecting it to the tires, etc. that can prevent the rotation from touching the road surface installed on the cart, etc., or by attaching a roller part device to the cart, etc. that rotates when the engine, etc. rotates on the spot to rotate the tires without changing the position of the car passing through during vehicle inspection, and connecting it to the wheels with a mechanism that changes the rotational energy of the roller part so that the wheels of the cart do not come into contact with the road surface. In order to prevent the road surface part that transmits the driving energy from freezing, water that has been kept at about 15 degrees by geothermal heat stored 5 meters underground or so is led to the vicinity of the road surface by pipes to prevent this, and the water is collected in the tank part by a motor pump and circulated. For emergency stops, etc., a stake is installed at the rear of the cart, etc., and if necessary, it can be lowered to the road surface to stop it quickly. Even when horizontal energy is obtained using technology such as linear motor cars, if a part of the magnetic field of the track of the linear motor car is cooled and covered with ice, and a sled is attached, the vertical levitation energy by electricity is saved and most of the electrical energy can be concentrated in the horizontal energy, which is efficient. The levitation energy when the linear motor car is running and the energy accelerating in the direction of travel are adjusted to save as much electrical energy as possible. A sled and the above-mentioned powered wheels may be attached to the linear motor car. The inside of the tunnel is made close to a vacuum state to eliminate loss 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. To cool the part where the sled is in contact, a long and thin heat absorbing plate from a freezer can be installed there, or a dedicated heat absorbing device can be used, or efficient temperature management using a large compressor and underground water at a constant temperature can be considered. The exhaust heat from the compressor can be used to run a Stirling engine, etc. 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 in the current roads, water in tanks installed 5 meters underground under roads and passageways is circulated using pipes to prevent freezing and excessive heat from the road surface. Circulating water can also be made to flow around the sleds using pipes to increase cooling efficiency in summer. Using plastic bottles, etc., create a space the size of a futon (it can be larger or smaller, the size can be changed) to keep the space cool in summer and not freezing in winter. Water from a tank installed about 5 meters underground is placed inside the plastic bottles through pipes and the plastic bottles are connected so that the water circulates and returns to the tank. Water can be pumped using motors, installed underground in high mountains, or sent to each home using large underground tanks linked to large facilities such as water purification plants, with a temperature close to 15°C even in summer.
