Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing an outline of the present invention.
The linear power generator of the present invention fills the first passage 1 and the second passage 2 formed of two cylindrical objects, the relatively high-density fluid 5 filled in the first passage 1, and the second passage 2. The relatively low density fluid 6 and the permanent magnet 9 attached to the inside or the outside of the fluid 6 are used, and the difference between the density of the fluid filled in the first passage 1 and the second passage 2 is utilized to make the first passage 1 And a plurality of movable bodies 8 that move in order in the second passage 2, a first guide passage 3 and a second guide passage 4 that communicate with each other of the first passage 1 and the second passage 2 at their ends, and a first guide It comprises a moving means for the movable body 8 provided in the path 3 and the second guide path 4 and a dielectric coil 7 wound over the entire length of the first path 1 and the second path 2.

Both the 1st channel | path 1 and the 2nd channel | path 2 which are used for the linear electric power generating apparatus of this invention consist of a cylindrical shape thing. As long as the cylindrical shape is hollow and the movable body 8 can move inside, the cross-sectional shape may be circular, elliptical, triangular, quadrangular, or polygonal. Both the passage 1 and the second passage 2 are circular. If the cross section is circular, the movable body 8 having a cylindrical shape, a shell shape, a spherical shape, or a rugby ball shape can be smoothly passed through the first passage 1 and the second passage 2, and is attached to the movable body 8. The distance between the permanent magnet 9 and the dielectric coil 7 wound around the first and second passages 2 can be kept constant.
The lengths of the first passage 1 and the second passage 2 may be the same or different. However, as will be described later, the longer the longer the theoretical power generation amount, the larger the maximum length according to the installation space. Advantageously.

The material of the first passage 1 and the second passage 2 is not particularly limited as long as it is a non-magnetic material and has a high insulating property and can hold a fluid therein, but synthetic resin is advantageous in terms of ease of processing. It is. Further, when strength is required, a metal or ceramic without magnetism may be used. Furthermore, it may be concrete or brick in large facilities, and the exterior can be reinforced with reinforced concrete.
Examples of metals that do not have magnetism include aluminum, tin, lead, copper, and the like, but alloys such as stainless steel (such as austenitic stainless steel) and brass that do not have magnetism are also preferably used.
Examples of the ceramic used for the first and second passages 1 and 2 of the linear power generator include glass, tile, brick, and ceramic pipe (for example, earthen pipe).

Synthetic resins used for the first and second passages 1 and 2 of the linear power generator include polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl acetate, polytetrafluoroethylene, acrylonitrile butadiene styrene resin, General-purpose resins such as acrylonitrile styrene resin and acrylic resin, polyamide, nylon, polyacetal, polycarbonate, modified polyphenylene ether, polyester, polybutylene terephthalate, polyethylene terephthalate and other engineering plastics, and polyphenylene sulfide, polysulfone, poly Super engineer plastics such as ether sulfone, polyether ether ketone, thermoplastic polyimide, and polyamideimide A.
Among these, polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl acetate, acrylic resin, polyester, polybutylene terephthalate, and polyethylene terephthalate can be preferably used because of low cost.

The first passage 1 is filled with a relatively high density fluid 5, and the second passage 2 is filled with a relatively low density fluid 6. Here, the fluids having different densities filled in the first passage 1 and the second passage 2 are nonflammable and can be used in any of gas and liquid as long as the viscosity is 2 × 10 ⁻³ Pa · s or less. it can.
As the incombustible gas, helium, nitrogen, oxygen, neon, argon, carbon dioxide, or a mixture thereof, or a mixture thereof, air, which is a mixed gas of nitrogen and oxygen, is preferable. Further, the air may contain gaseous water (water vapor).

As the incombustible liquid, a liquid having a large electric resistance is preferable, and water is generally used, but this water can dissolve an inorganic compound or an organic compound. The density of the liquid can be appropriately adjusted depending on the amount of the dissolved inorganic compound or organic compound. Inorganic compounds that can be dissolved in water include sodium chloride (salt), calcium chloride, magnesium chloride, calcium chloride, sodium sulfate, calcium sulfate, magnesium sulfate, calcium sulfate, sodium nitrate, calcium nitrate, magnesium nitrate, calcium nitrate, and phosphoric acid. Examples of the salts include sodium, calcium phosphate, magnesium phosphate, and calcium phosphate.
Organic compounds that can be dissolved in water include alcohols such as methanol, ethanol, propanol, butanol and glycol, acids such as formic acid, acetic acid, butyric acid, lactic acid, malic acid and succinic acid, ketones such as acetone and methyl ethyl ketone, and fatty acid sodium And surfactants such as alkylbenzene sulfonates. Among them, ethanol, acetic acid, and fatty acid sodium are preferable because they have a small environmental load.

In the linear power generator of the present invention, typically, the first passage 1 is filled with water and the second passage 2 is filled with air. In this case, since the buoyancy and gravity are used for the movement of the movable body 8, the first passage 1 and the second passage 2 are installed in a direction perpendicular to the ground.
Furthermore, if a device capable of controlling the atmospheric pressure is attached, if the first passage 1 can be filled with a relatively high pressure gas and the second passage 2 can be filled with a low pressure gas, a pressure gradient can be created. The movable body 8 can be moved from the high pressure side to the low pressure side. In this case, since the buoyancy and gravity are not related to the movement of the movable body 8, the first passage 1 and the second passage 2 are not limited to the vertical direction, and may be installed in the horizontal direction.

A plurality of movable bodies 8 are movably accommodated in the first passage 1 and the second passage 2. The movable body 8 is provided with a permanent magnet 9 on the inner side or the outer side thereof, and the first passage 1 and the second passage 2 are moved using the difference in density of fluid filled in the first passage 1 and the second passage 2. The magnetic field generated by the permanent magnet 9 moves in order and passes through the dielectric coil 7 wound around the first passage 1 and the second passage 2 to generate a current.
In the linear power generator of the present invention, typically, the movable body 8 floats in the relatively high-density fluid 5 in the first passage 1, and the relatively low-density in the second passage 2. The fluid 6 falls. By intermittently and repeatedly circulating this intermittently, it is possible to generate electric power by using the natural energy of buoyancy and drop force to perform cyclic movement.

The shape of the movable body 8 is not particularly limited. The movable body 8 moves without any obstacle in the first guide path 3 and the second guide path 4 that communicate the first path 1 and the second path 2 and the first path 1 and the second path 2 with each other. Any structure can be used, but typically, it has a cylindrical shape, a shell shape, a spherical shape, a rugby ball shape, or the like. Movable member 8, it is necessary to determine the direction of the time progression, mounting the weight 10 as a traveling direction setting unit as the center of gravity of the movable member 8 to the portion to be the rear when traveling a relatively dense fluid 5 Medium It is good to do. In order to determine the traveling direction of the movable body 8, a tail blade or a tail fin may be attached instead of the weight 10. The weight 10 not only determines the traveling direction of the movable body 8, but also can adjust the weight of the movable body 8, that is, the specific gravity. Usually, the weight 10 is made of metal or ceramic.
As the metal used for the weight 10, iron or lead can be preferably used. As the ceramic used for the weight 10, a ceramic plate, cement or brick can be preferably used.

When the shape of the movable body 8 is a cylindrical shape, a shell shape, a spherical shape, or a rugby ball shape, the horizontal cross section with respect to the movable body 8 that floats or falls is the size of the cross section of the first and second passages 1 and 2. The size of the movable body 8 is determined as long as the movable body 8 can move through the first and second passages 1 and 2 without obstacles. That is, the outer diameter of the horizontal section of the movable body 8 is preferably 80 to 95% of the inner diameter of the first passage 1. If the outer diameter of the horizontal section of the movable body 8 is 80% or less of the inner diameter of the first passage 1, the distance between the movable body 8 and the dielectric coil 7 wound around the first and second passages 2 is increased. The power generation efficiency may be reduced. On the other hand, if the inner diameter is 95% or more, the movable body 8 is subjected to fluid resistance during the movement thereof, and the moving speed of the movable body 8 is slowed down, which may reduce the power generation efficiency.
On the other hand, the length (height) of the movable body 8 is determined by the moving means of the movable body 8 provided in the first guide path 3 and the second guide path 4. Usually, it is in the range of twice to half the diameter of the horizontal section of the movable body 8.

The movable body 8 is provided with at least one permanent magnet 9 inside or outside thereof. The number of permanent magnets 9 to be mounted is usually 1 to 1000 depending on the size of the magnet, and the line connecting the N pole and the S pole with respect to the moving direction of the movable body 8 is parallel or constant (for example, ± 45). It is arranged with an inclination of °. When a plurality of magnets are mounted, it is preferable that the magnets are arranged in parallel with each other, and the S poles and the N poles are arranged in the same direction.
As the permanent magnet 9, an alnico magnet, KS steel, MK steel, a ferrite magnet, a samarium cobalt magnet, a neodymium magnet, or the like is known, and any permanent magnet 9 can be used for the movable body 8 of the present invention. Of these, ferrite magnets, samarium cobalt magnets and neodymium magnets having high magnetic flux density and strong magnetic force can be preferably used.

When a plurality of permanent magnets 9 are attached to the movable body 8, they are arranged so that the permanent magnets 9 do not contact each other and the S poles and N poles of each magnet face each other. When the permanent magnet 9 is mounted inside the movable body 8, a space for storing the magnet may be provided independently. When the permanent magnet 9 is mounted on the outer periphery of the side surface of the movable body 8, a slit for storing the magnet may be provided independently. In a typical linear power generation, the movable body 8 repeatedly passes through water or salt water and air, so that the permanent magnet 9 is likely to rust. For this reason, the permanent magnet 9 attached to the movable body 8 is subjected to a surface treatment to prevent contact with fluid and air. The surface treatment material is not particularly limited, and any surface treatment such as a general paint or plating can be used as long as the permanent magnet 9 does not cause rust.
A groove 11 serving as a fluid flow path is provided on a side surface of the movable body 8. This is provided so that when the movable body 8 moves in the first passage 1 and the second passage 2, there is no place for the fluid in the traveling direction of the movable body 8 to obstruct the movement of the movable body 8. By this groove 11, when the movable body 8 floats in the first passage 1, the fluid in the traveling direction of the movable body 8 flows to the rear of the movable body 8 through the groove 11 provided on the side surface of the movable body 8. can do.

  Further, the groove 11 provided on the side surface of the movable body 8 is a spiral groove 11 that is not parallel to the moving direction of the movable body 8 but has a certain inclination with respect to the traveling direction of the movable body 8. It is preferable. This is for applying a rotational force to the movable body 8 when the fluid passes through the groove 11 engraved in a spiral shape, and the movable body 8 can advance linearly by rotating. When the spiral groove 11 is not present on the side surface of the movable body 8, the movement of the movable body 8 proceeds with irregular changes, and it becomes difficult to perform a smooth circular movement. There is no restriction | limiting in the rotation direction of the movable body 8, and rotation may be either clockwise or counterclockwise with respect to the advancing direction.

The material for forming the movable body 8 is not particularly limited as long as it is lightweight and can provide buoyancy. However, if importance is attached to light weight, a material that can mold the hollow movable body 8 is preferable, and a non-magnetic material is preferable. Examples thereof include metals, ceramics, and synthetic resins.
Examples of the nonmagnetic metal forming the movable body 8 include titanium, aluminum, copper, brass, and stainless steel having no magnetism (such as austenitic stainless steel). Furthermore, it is good also as fiber reinforced metal (FRM) which reinforced these metals with the fibrous substance of carbon or ceramics.
Examples of the ceramic forming the movable body 8 include glass and ceramic molded bodies.

As the synthetic resin that the movable body 8 forms, general-purpose resins such as polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl acetate, polytetrafluoroethylene, acrylonitrile butadiene styrene resin, acrylonitrile styrene resin, acrylic resin, Engineer plastics such as polyamide, nylon, polyacetal, polycarbonate, modified polyphenylene ether, polyester, polybutylene terephthalate, polyethylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, polyphenylene sulfide with higher heat distortion temperature, Polysulfone, polyethersulfone, polyetheretherketone, thermoplastic polyimide Thermoplastic synthetic resin such as polyamide-imide can be used. Of these, unsaturated polyolefins such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, and polybutylene naphthalate can be preferably used.
Molding techniques for molding hollow molded bodies using these synthetic resins include vacuum pressure molding, extrusion molding, injection molding, calendar molding, blow molding, stretch blow molding, and compression molding. Existing molding techniques such as these can be used.

Furthermore, fiber reinforced plastics (FRP) obtained by reinforcing these synthetic resins with glass fibers, carbon fibers, or strong resin fibers can be preferably used. Among these, glass fiber reinforced plastic (GFRP) and aramid fiber reinforced plastic (AFRP) can be preferably used from the viewpoint of strength.
The fiber reinforced plastic (FRP) molding method includes hand lay-up method and spray-up method in which reinforcing fiber is laid on the mold and the resin mixed with curing agent is defoamed and laminated, and reinforcing fiber and resin are pre-bonded. There are the SMC press method in which the mixed sheet-like material is compression-molded with a mold, the RTM method in which resin is injected into a mating die in which reinforcing fibers are laid like injection molding, etc. What is necessary is just to select suitably according to a shape.
In order to increase the buoyancy of the formed hollow movable body 8, the hollow portion may be filled with helium. As a method of filling helium, a balloon filled with helium may be inserted into the hollow portion of the movable body 8.

On the other hand, from the viewpoint of ease of processing, a foamed synthetic resin containing many bubbles in it can be preferably used. Examples of the foamed synthetic resin include polyurethane, polystyrene, polyolefin, phenol resin, polyvinyl chloride), urea resin, silicone, polyimide, and melamine resin. Among these, polyolefins including polyethylene and polypropylene, polyurethane, and polystyrene can be preferably used.
There are various known techniques for producing a molded body from a foamed synthetic resin, such as cast foam molding, melt foam molding, solid phase foam molding, and the like. These molding techniques can be widely used for manufacturing the movable body 8 of the present invention.
If the molded foamed synthetic resin has closed cells, these bubbles may be filled with helium in order to increase buoyancy.
When the movable body 8 is manufactured, manufacturing cost and functionality are emphasized, and the material may be appropriately selected from the above materials.

A first guiding path 3 and a second guiding path 4 are provided to communicate the first path 1 and the second path 2 with each other at their end portions, and a movable body 8 is provided in the first guiding path 3 and the second guiding path 4. The moving means is provided. Since there are various methods for moving the movable body 8, it is important to devise the shapes of the first guide path 3 and the second guide path 4 so as to match the system.
For example, as a means for moving the movable body 8 provided in the first guide path 3, there is a method in which a down slope bypass 20 is provided in the first guide path 3 and the movable body 8 is slid down using the bypass 20.
This sets the upper end portion of the first passage 1 to a position higher than the upper end portion of the second passage 2, and the first guide passage 3 is inclined from the upper end portion of the first passage 1 toward the upper end of the second passage 2. It is formed as a downward slope, and the tip of the slope is connected to the second passage 2.
With this structure, the movable body 8 that has floated up the first passage 1 jumps out of the water surface, enters the upper first guide passage 3, slides down the down slope, reaches the second passage 2, and falls through the second passage 2. be able to.

The force by which the movable body 8 jumps out of the water surface may be the inertia force of the buoyancy of the movable body 8 or may be due to the magnetic force generated by the coil wound around the upper end portion of the first passage 1. When the magnetic force is generated by applying an instantaneous current to the coil wound around the upper end of the first passage 1 to form a magnetic field, the permanent magnet mounted on the movable body 8 reacts to this and the movable body 8 moves to the water surface. The existing technology used in linear motor cars can be used.
Further, a technique using this magnetic force can be used to guide the movable body 8 protruding from the water surface to the slope of the first guide path 3.
Alternatively, a guide plate may be provided on the extension of the first passage 1, and the movable body 8 protruding from the water surface may be guided to the slope. The guide plate is a plate having a flat surface provided directly above the first passage 1 and higher than the upper end portion, and is installed with an inclination so that the movable body 8 jumping out of the water surface moves to the slope after the collision.
Further, the movable body 8 may be guided to the bypass 20 by the momentum of the fluid 5 to be replenished from a replenishment pipe 18 described later.
Furthermore, an extension portion extending upward is formed in the first passage 1, an opening / closing device is provided between the extension portion and the bypass 20 formed in the first guide path 3, and the supply pipe 18 is closed with the opening / closing device closed. Alternatively, after the fluid 5 is replenished, the opening / closing device is opened at once and the movable body 8 is allowed to flow to the bypass 20 together with the fluid 5.

At the connection position of the bypass 20 and the second passage 2, the direction of the movable body 8 supplied to the second passage 2 is determined. That is, the direction of the N pole and the S pole of the movable body 8 falling through the second passage 2 is preferably opposite for each movable body, and the movable body falling next to the movable body 8 having dropped the N pole downward. 8 should drop the south pole down.
By moving the N pole and the S pole of the movable body 8 falling in the second passage 2 in the opposite directions for each movable body, the movable body 8 that has dropped first and the movable body that has fallen next at the exit of the second passage 2 are provided. A repulsion of magnetic force occurs between the body 8 and the movable body 8 can escape from colliding with the bottom of the second passage 2. Thereby, generation | occurrence | production of a noise and a vibration can be suppressed.
Further, the magnetic forces repelling each other also serve as a propulsive force for moving the movable body 8 that has been dropped to the hermetic chamber 12 described later.

A second guide path 4 is connected to the exit end of the second passage 2, and a moving means for moving the movable body 8 to the first path 1 is provided in the second guide path 4.
For example, the moving means of the movable body 8 provided in the second guide path 4 is the airtight chamber 12 provided at the entrance or exit of the second guide path 4. The hermetic chamber 12 is a device provided immediately below the first passage 1 or the second passage 2, and an introduction port 15 for introducing the movable body 8, a delivery port 14 for sending the movable body 8, and a relatively high-density fluid 5. Has a discharge port 17 for discharging water. Each of the introduction port 15, the delivery port 14, and the discharge port 17 is equipped with an opening / closing unit composed of a sliding double shutter.

The conceptual diagram for demonstrating the airtight chamber of this invention in FIG. 2 was shown. (1) is an airtight chamber provided directly below the first passage, and (2) is an airtight chamber provided immediately below the second passage.
When the hermetic chamber 12 is provided at the outlet of the second guide path 4, the hermetic chamber 12 is directly connected to the lower end of the first passage 1 as shown in FIG. One end of the second guide path 4 is connected to the second passage 2, and the other end is connected to the airtight chamber 12. The second guide path 4 forms a gentle downward slope from the connecting portion of the second passage 2 toward the hermetic chamber 12.
An introduction port 15 for introducing the movable body 8 into the hermetic chamber 12 is provided at a connection portion between the second passage 2 and the hermetic chamber 12 on the side surface of the hermetic chamber 12. An opening / closing part 19 is provided. A delivery port 14 for delivering the movable body 8 is provided at a connection portion between the upper surface of the hermetic chamber 12 and the first passage 1. A second opening / closing part 13 is provided at the delivery port 14 so as to be freely opened and closed. A discharge port 17 for discharging a relatively high-density fluid 5 is provided on the lower surface or lower side of the airtight chamber 12. A third opening / closing part 16 is installed at the discharge port 17.

On the other hand, when the hermetic chamber 12 is provided at the entrance of the second guide passage 4, as shown in FIG. 2 (2), the hermetic chamber 12 is directly under the second guide passage 4, and the lower end of the second passage 2 is the air passage. It communicates directly with the closed room 12. One end of the second guide path 4 is connected to the airtight chamber 12, and the other end is connected to the first passage 1. The second guiding path 4 forms a gentle upward slope toward the connecting portion with the first passage 1.
An inlet 15 for introducing the movable body 8 into the hermetic chamber 12 is provided at the connecting portion between the upper portion of the hermetic chamber 12 and the second passage 2, and the first opening / closing portion 19 is openable and closable at the inlet 15. Provided. On the surface of the hermetic chamber 12 facing the first passage 1, a delivery port 14 for sending out the movable body 8 is provided, and the second guide path 4 is communicated. A second opening / closing part 13 is provided at the delivery port 14 so as to be freely opened and closed. A discharge port 17 for discharging a relatively high-density fluid 5 is provided on the lower surface or lower side of the airtight chamber 12.

The roles of the opening / closing sections 13, 16, and 19 are to block between the first passage 1 and the second passage 2 to prevent the mixing of the respective fluids 5, and to open and close at a predetermined timing to move the movable body 8. And to temporarily release the relatively high-density fluid 5 in the hermetic chamber 12.
In order to enable this operation, for example, the structure of the opening / closing part is as follows.
The opening / closing part has a double structure of a lattice shutter that maintains strength and a flat shutter that maintains airtightness. The lattice shutter and the flat shutter release the flow of relatively high-density fluid 5 by slightly shifting the opening and closing timing. By making the one tempo faster, the pressure applied to the flat shutter can be reduced.
These opening / closing sections are slidable, and the opening / closing timing is controlled by computer control, whereby the structure of the opening / closing section can be simplified.

The relatively high-density fluid 5 discharged from the hermetic chamber 12 can be discharged downstream as it is, but can also be recovered and used.
There are various methods for recovering the discharged relatively high-density fluid 5, but it is only necessary to uniformly provide a recovery tank and return the recovered fluid to the first passage 1 via the supply pipe 18. .
Or you may make it flow in into the airtight chamber 12 from a collection tank. As a method for returning the fluid 5 from the recovery tank to the hermetic chamber 12, transfer by a pump, transfer by compressed air, and a method of moving the recovery tank together with the recovered fluid 5 to a higher position and pouring it into the hermetic chamber 12 using a drop. Etc. are considered.

On the outside of the inner walls of the first passage 1 and the second passage 2, windings are wound along the circumference of the cross section of the cylindrical structure to form a dielectric coil 7. There is no restriction | limiting in particular in the coil | winding wound, The coil | winding used for a generator can be used normally. The winding is generally a copper wire, and the thickness and length of the winding can be appropriately selected according to the scale of power generation. The winding is preferably tightly wound over the entire length of the first passage 1 and the second passage 2.
The dielectric coil 7 may be installed by dividing the length direction of the first passage 1 and the second passage 2 into a plurality of pieces. It is preferable that the dielectric coil 7 is divided for each length according to the length of the movable body 8 in the moving direction. By dividing the dielectric coil 7 in accordance with the length of the movable body 8, each energy of the movable body 8 can be recovered.

FIG. 3 is a schematic diagram for explaining the energy balance when one movable body 8 of the present invention performs one cycle.
A plurality of movable bodies 8 equipped with permanent magnets 9 are intermittently levitated sequentially from the bottom of the first passage 1, and current can be generated in the dielectric coil 7 in this process. Next, a current can be generated in the dielectric coil 7 by dropping the second passage 2.
When the effect of the present invention is calculated, for example, when the relatively high-density fluid 5 is water and the relatively low-density fluid 6 is air, the movable body 8 has the first passage 1, the first guide passage 3, The energy obtained from the buoyancy and the drop force is theoretically equal to the potential energy of the makeup water when the two passages 2 and the second guiding path 4 (hereinafter referred to as a twin pathway) are moved for one cycle.

落下エネルギーをＥｄとすると、落下エネルギー（Ｅｄ）は〔式２〕で表される。

That is, when the buoyancy energy is Eu, the buoyancy energy (Eu) is expressed by [Equation 1].

When the drop energy is Ed, the drop energy (Ed) is expressed by [Equation 2].

補給水の位置エネルギーをＥｗとすると、補給水の位置エネルギー（Ｅｗ）は〔式４〕で表すことができ、浮力エネルギー（Ｅｕ）と落下エネルギー（Ｅｄ）を合計したエネルギー（Ｅｕ＋Ｅｄ）は補給水の位置エネルギー（Ｅｗ）と同一になる。

The energy (Eu + Ed) obtained by adding the buoyancy energy (Eu) and the fall energy (Ed) can be expressed by [Equation 3].

When the potential energy of makeup water is Ew, the potential energy (Ew) of makeup water can be expressed by [Equation 4], and the energy (Eu + Ed) obtained by adding the buoyancy energy (Eu) and the falling energy (Ed) is the makeup water. It becomes the same as the potential energy (Ew).

可動体８がツインパスウェイを１周するときに補給する水の位置エネルギーは、〔式６〕となり〔式５〕で発生した電気エネルギーと一致する。

The theoretical value of the electric energy generated when one of the movable bodies 8 makes one round of the twin pathway of the present application is expressed by [Equation 5] by combining the floating and the falling. However, efficiency is 1 and friction and resistance are not included.

The potential energy of water to be replenished when the movable body 8 makes one round of the twin pathway is [Equation 6], which coincides with the electric energy generated in [Equation 5].
