CONSTITUTION: A natural energy conversion system comprises following steps. The fluid energy is converted into the linear movement of a device driven by flow force. The liner movement of the device is transmitted to the liner movement of the power convertor through a mechanical connection device. Electricity is generated or power is converted by the flow of compressed fluid because the mover of the power convertor is moved. The power is transmitted to a power consumption place through a hose or a wire(49).

Description

Natural Energy Conversion System

The present invention utilizes natural forces, ie renewable energy such as sunlight, wind, ocean currents and algae, to convert it into power such as electricity or hydraulic or pneumatic.

Fossil energy is based on photosynthesis, but it is matured at high temperatures and pressures in the earth's crust over one million to 100 million years, and is converted into physically new material. The advantages are high energy density and easy transportation (straw straw or firewood = 12 ~ 15MJ / Kg, coal = 25 ~ 30MJ / Kg, crude oil or refined oil = 42 ~ 44MJ / Kg).

Textile mills and sawmills before the Industrial Revolution were located in mountain valleys for hydropower. In addition to fossil fuels, the plant was equipped with boilers and steam engines to have independent energy sources, which started production activities independently of nature, and urbanization proceeded. Fossil fuels react rapidly with the oxidant to produce heat, which is converted into mechanical drive energy through cycles that do not deviate from the second law of thermodynamics to produce work or power. The mechanical energy conversion efficiency is around 20-30%, the rest is a waste of warming the surroundings, and it causes heat island phenomenon in the city.

Since fossil fuels come from plant and animal waste, they contain sulfur (2% for coal, 1% for oil and natural gas), contaminating air with combustion, causing global warming. Therefore, renewable natural forces (sunlight, wind power, river flow, ocean currents, and tidal currents) should be used.

Natural forces have lower energy densities than fossil fuels and lower power densities. Compared to the area of coal mine or oil field, the output of 1,000 ~ 10,000W / m ² is about 10W / m ^{2 of} hydro power, 2W / m ^{2 of} wind power, 20W / m ^{2 of} solar power, 0.45W / of sugarcane ethanol in Brazil. The low power density, such as m ² , requires a large area of land or sea.

Since 87% of the humanity's current energy (15 TW in 2004) depends on fossil fuels, natural forces must be collected and transmitted at remote sites (deserts, mountain canyons, and seas).

Natural forces (sunlight, wind, ocean currents, and algae) have low power densities, which results in lower power productivity compared to the cost of an energy harvesting device.

Winds are low in density (1.2041 kg / m ³ ), and algae are high in density (1,025 kg / m ³ ) but low in speed (Gulf currents = 2.1 m / s, woolly algae = 3.6 m / s). In order to utilize these natural forces, it is necessary to increase the power density as if the lens or mirror is focused on the sunlight. Lens firings were carried out in ancient China, and Archimedes repelled the Roman fleet with a well-polished shield.

Hydroelectric power captures rivers into dams and flows through narrow channels with different levels of water to achieve high flow rates. However, dams have a problem of destruction of ecosystems along with huge civil works. The kinetic energy P of the flow field is expressed as P = 0.5ηρＶ ³ A by the fluid density ρ, flow velocity Ｖ, and swept area A. η is the power generation efficiency, and the current horizontal axis wind turbine is 0.4 ~ 0.5, reaching 80% of Betz's theoretical maximum of 0.593. Therefore, either the fluid density must be increased or the sweep area must be increased.

The present invention is to solve the method and apparatus for obtaining power from a remote location by using a natural force, such as erecting a dam without using a natural force, to increase the density of the fluid or to increase the sweep area.

Figure 1 shows a prior art floating windmill with three blades. The area A written here is the circle 1 drawn with a dotted line. In other words, the blade is rotated and used area.

Figure 2 shows that the floating windmill is not mooring and the blade is rotated and moved from t = 0 to t = 1 perpendicular to the wind direction. In this case, the area A written per unit time is the area (2) drawn by the comb line in Fig. 3.

Figure 4 shows a typical generator with a water turbine. The configuration consists of a sail 3, a mast 4, a water wheel 5, and a generator 6. When the ship moves from the position of t = 0 to the position of t = 1 by the wind force as shown in Fig. 5, the ship absorbs the kinetic energy of the wind contained in the area covered by the sail and the mast (7). The aberration 4 and the generator 5 will produce electricity. By using the kinetic energy of the gas, the aberration generator makes relative motion with the liquid, and from the standpoint of the energy converter, it has the effect of increasing the used area and increasing the density of the fluid.

Figure 6 is a prior art consisting of a float (11), aberration (12), generator (13), a floating water flow generator bound to the pile (9) and the rope (10) in the middle of the river flowing in the direction of the arrow (8). The key 14 is added to the control surface. When the key is operated, the hull-shaped float changes the fluid force coefficient (lift coefficient, drag coefficient, and moment coefficient) with respect to the river and moves in the vertical direction with respect to the river flow. However, because it is constrained by the string, the pendulum moves in the section (arc) of the range allowed by the float ratio of the circle around the pile (9). Therefore, the aberration increases the waste area A in absorbing the flow energy. To increase the period of the pendulum movement, lengthen the line (10).

Figure 7 shows that when a glider-shaped underwater kite (15; paravane) moves on a river or algae indicated by an arrow (8), it pulls the generator carrier (17) through the tow line (16), and the generator carrier is a rail. By making relative motion with respect to (18), the wheel 19 rotates and the motor (permanent magnet or electromagnet) of the generator linked to the wheel rotates to generate electricity to the stator (wire coil) of the generator. Electricity can be transferred to the rails via a brush like an electric vehicle. Underwater flight posture operation of the underwater kite is connected to the two or four wire ropes like the acrobatic bands to manipulate the length of the wire ropes, or it sends the wired signal to the electric servo motor as if it sends a wireless control signal to the control plane of the model airplane. Maneuver the control surface of the underwater kite. In order to reduce the time to change the direction at both ends of the rail to store the kinetic energy of the generator carrier body as the elastic energy of the mechanical or pneumatic spring (20) to return to the kinetic energy of the generator device carrier changed direction. Or, by constructing a high altitude at both ends of the rail, the kinetic energy of the generator carrier is changed to potential energy and then returned to the changed kinetic energy.

The example in Figure 7 is based on the premise of building bridges and rails at sea or rivers, but at sea there may be a problem of impeding vessel traffic. If you try to install such a device underwater, it is difficult to transfer the generated electricity to a rail consisting of wires or conductors through a brush. In this case, use a linear generator. Like the linear motor, the linear generator has a stator composed of iron cores wound with wires, and induction electricity is generated when a mover (permanent magnet or electromagnet) moves along the stator. Therefore, the electric transmission through the brush can be omitted.

The problem here is that the speed of the algae is not so high, so the speed of the motor carrier of the generator is not high, and thus the power generation efficiency is low (the linear speed of the rotor of a general rotary generator is 40-200 m / s). Therefore, it is necessary to increase the circumferential rotational linear movement speed of the exerciser by increasing the relative speed with the stator through the gearbox interlocked with the wheel or the rotation speed doubling device such as the timing belt and the pulley or by increasing the radius from the rotational center supporting the rotational movement of the athlete. There is. In the example shown in Figure 7, the rail consists of an open circuit. In addition to having to change direction at both ends, there is a problem that only one generator is accommodated. In order to improve this, the rail is configured in a closed loop. Fig. 8 is an example of a closed loop rail composed of a stator of a linear generator composed of an iron core 21 and an electric wire coil 22, as shown in Fig. 9, showing the starting point of an upstream movement section of a river or seawater. A plurality of carriers 24 of the linear generator apparatus 25 with a vane 23 driven by absorbing the flow force of the seaweed along the rail having a high altitude is driven. In the case of vanes or blades, only the posture control on one axis is required, so the device is simple.However, in the case of river water or algae, the high velocity near the surface of the water makes the 3-axis posture control and distance control possible. A device like a bundled hydrofoil is good for speeding up and sweeping area.

The height of the track not only has the advantage of converting and storing kinetic energy into potential energy, but also the vertical motion along the height of the track is a vertical motion with respect to the flow of the fluid, so that the lift mode can be maintained across the flow of the fluid. It can be used to help increase the area used. Therefore, if the track does not cost a lot of construction cost, it is possible to incline up and down each section (ie, crossing, crossing, crossing) to increase power productivity.

The differences from the prior art in wind power generation or dam-free water generation are as follows.

In the case of windmills or aberrations (prior art), the turbine blade absorbs the flow force and performs linear motion, but cannot move indefinitely, so it is constrained by the rotation axis (hub) and turns into a rotation movement about the rotation axis, and the blade absorbs the flow force. The drive speed of the blade near the rotational axis is slowed down, and the speed near the tip blade is increased by being acted on at the same time. Therefore, the length of the blade in order to increase the sweep area is subject to the constraints of sound velocity or cavitation. In the case of the vertical shaft turbine (H-rotor, Bosch Schneider propulsion), there is a separate arm for transmitting the movement of the blade does not have to twist the blade, but in the end, the improvement in the constraint is not so large as to transmit the rotational movement as it is.

In the present invention, a mechanism (eg, a generator carrier) receiving linear movement by a mechanism (eg, a sail) that absorbs a flow force and performs a linear movement (eg, a mast) and a linear movement of the mechanism (eg, a mast) has a density. It generates electricity by driving the generator of the generator through mechanisms such as wheels and aberrations while doing relative movement with high water, ground or rigid structures (eg rails). By dividing a role into a mechanism driven by absorbing a flow force and a linear movement of the mechanism, the area used can be easily increased because it is relatively free from the above constraints. It is possible to select the location of power generation equipment widely and to change the density of the fluid, and at the same time limit the damage caused by obstacles such as logs, rope fragments, etc. in river stones, algae, etc. to a mechanism that absorbs the flow force. .

Looking back at the case of Figure 6, the traction line 10 bears both the flow force experienced by the float 11 and the drag along the rotation to develop the aberration 12. Thus, the range in which the aberration 12 can be moved is the arc 26, which is part of the circumference of which the length of the traction line 10 is the radius and the pile 9 is the center of rotation, or the actual effective sweep area is perpendicular to the fluid flow (river). The length of the string 27, which is one component, is multiplied by the diameter of the aberration 12. The effective string 27 of the path where the aberration 12 travels is placed close to the center of rotation 9 of the tow line to increase the effective sweep area within the range of the wire or tow line of a given length. To this end, a mechanism capable of receiving aerodynamic forces, such as a sail, is installed on the float 11 to generate a force (lift in air force) perpendicular to the string 27, which is an effective movement path of the float and aberration, to the river 8. To offset the drag caused by float and aberration. The advantage of this method is that the wind and water flows can be converted into a single device.

Figure 10-1 shows the relative velocity V _relative as the float (11) moves to V _float to the right in the figure where the stream (8) flows at the velocity of V _water . And the resulting drag L _float and drag D _{float on the float} , and the drag D _turbine derived from the rotation of the aberration, the lift L _a and drag D _a generated by aerodynamically energized mechanisms such as sails. The figure above shows the balance of. Figure 10-2 shows a view of the float in the direction of travel, in which the direction of the flow of water (28) is the balance between the forces of the forces of the air force (27) and the forces in the flow of the river. ). In order to endure these moments, the weight of the ballast is used to put the weight center below the buoyancy center to have stability or to cater for the catamaran and the multi copper line to put the buoyancy center on the center of gravity. This method has the advantage of continuing stability even when going or stopping, but there is a problem that the weight of the structure increases and the resistance occupied by the hull is large.

Figure 11 is an example of minimizing the rotation moment by constructing a structure that supports the bending moment of the mechanism driven by aerodynamic force such as sail or airfoil and the mechanism driven by water current such as hydrofoil. Since the rotation moment is generated only when traveling by pneumatic or water flow force, it can be generated only when the force to offset it is advanced. When the sail 30 is inclined toward the center of the structure, the moment of action of the lift force applied to the sail passes near the center of mass of the structure, thereby giving a rotation moment generated by reducing the moment arm.

In the structural design, if the structure is able to support only tensile force rather than the structure that must withstand the bending moment, most of the weight is reduced to 1/5. Figure 12 shows the rotational moments generated by the wind on the sails and masts (31). The hydrofoil (32) (aka Hapa: HAPA: acts as an independent keel, unlike conventional keels attached to the hull). It is offset by the tension force through the rope 33. Here, in order to ensure that the hydrofoil is always in the water, a mechanism 36 for adjusting the angle of attack of the water is used in conjunction with a float 34 or a surface sliding vane 35 capable of detecting the position of the water surface (eg, UP3762353). , WO86 / 05757).

Underwater hydrofoils that interlock with devices that can detect the position of the water surface, such as floats and surface sliding wings, have the advantage of automatically maintaining a constant depth with a simple structure, but are sensitive to intermittent conditions such as waves. If you move on the windy side and move to the windy side, the mechanisms associated with the hydrofoil hapa are inverted, so if you want to use only one, you have to use a very complicated mechanism or two on the left and right. On the other hand, the harmonic resistance of fast-moving objects on the surface of the water is proportional to the weight of the object, so it is important to reduce the weight and to reduce the surface area of the object moving in the water near the water surface.

Another way to keep the hydrofoil always submerged is shown in Figure 13. In Figure 13, the hydrofoil hap 36 is the main hydrofoil 38 for bearing the tensile force due to the aerodynamic force transmitted to the rope 37, the subsidiary fin 39 for adjusting the depth, and the attitude of the hydrofoil lower wave. The control surface 40 is comprised. In order to know the depth of the hydrofoil, a water gauge 41 capable of measuring the depth of water is mounted on the center or the fuselage 42 of the main hydrofoil 38. On the other hand, another depth gauge 43 is mounted on one side (left or right) of the main hydrofoil so as to know the posture of the hydrofoil (either straight or upside down). (Fig. 13 is the case installed at the center and left side of main hydrofoil.) You can know the attitude of hydrofoil by comparing the depth of water depth gauge (41) and another depth gauge (43). If not, it is commanded to the control surface 40 to control the posture of the secondary wing 39 to meet him.

The technology of sails for harnessing the power of wind has been improved for over thousands of years.In the early days, the use of animal skins led to the development of textiles, from synthetic natural fibers to light and unstable synthetic fabrics such as nylon, dark and aramid fibers. Write Sails have the advantage of being rolled up and bloomed, but the sails themselves do not offer very good aerodynamic performance (such as high lift ratios). Therefore, some wings sails (wingsails or airfoils) are used, such as those used in aircraft. Wing sails have a rigid structure consisting of aluminum ribs and aluminum skins like aircraft wings, or a flexible structure in which only the mast is rigid and surrounded by fabric skin with ribs and bartons made of flexible materials around them. Shall be. Wing sails have improved aerodynamic performance but do not bloom, which is accompanied by a complex mechanism. Therefore, they also use rotorors. Rotary wing sails allow windmills, such as vertical windmills or horizontal windmills, to be mounted on the mast and auto-rotate. Instead of gaining power by turning the windmill or gaining the thrust of the screw, the free-wheeling windmill can be fixed with a brake to fold the sails, or the pitch angle of the windmill's wings can be adjusted to provide a finer footprint for the effective sweep area of the rotor blade sail. Adjustment is possible. Conventional sails, wing sails, rotary wing sails are limited in size because they use a mast that bears the bending moment in transmitting wind force or motion accordingly.

By omitting the mast in Figure 12, a mastless sail (eg UP4497272), ie a flexible kite or flexible wing, is one way.

It was used thousands of years ago and was initially used with silk or paper on one or more skeletons (spas) made of bamboo. In 1951, the self-inflating flexible kite (UP2546078) of the Logallo couple showed the possibility of a kite-free kite with a single canopy and bridle line, and a double-layered canopy. It is divided into a number of cells with a rib shaped rib, and it is inflated by a ram air that is introduced through an opening in the front part, and the wing that is inflated by Salber's ram air (UP3285546) maintains the shape of a wing without any skeleton control. And improved stability. After that, the inflated bladder in front of the Genu Brothers is filled with compressed air by a hand pump or the like, which inflates itself and supports structural forces such as bending moments on the wings, that is, leading edge inflatable kite. (UP4708078), kitesurfing developed while being able to fly again on the water.

Wind speed is generally proportional to altitude. The flow force is proportional to the square of the velocity and the flow energy is proportional to the third power of the velocity. Since the bending moment is the distance multiplied by the force, it can be considered that it is approximately proportional to the third power of the speed. Therefore, if the wind is transmitted by the mast, there is no technical benefit of the enlargement. However, if the tensile force is transmitted by the traction line like kites, the cost of the structure is proportional to the square of the speed, but the energy produced is proportional to the third power of the speed.

The use of asymmetric airfoils on wing sails requires the addition of complex mechanisms (e.g. UP 711456), but the kite is free to control the distance and posture, so that the aerodynamic performance is optimal even when the wind direction changes due to reversing or turning. You can take a stance to make a difference.

Wings that are inflated by ram air are used for paragliding, and fore-wing blades are used for kite surfing, but there are points to improve each. The ram air wing has good aerodynamic performance because it maintains the wing shape by the pressure of ram air drawn through the open hole in the front part, but the pressure is weak so that it does not endure the bending moment in the span direction and the cord direction. Because of the need to spread the bending moment by attaching the bridle, the drag caused by the bridle will increase, and the bridle may be tangled. Instead of installing the bridle line at the both ends of the span in front of the wing extension, the entire wing forms a semi-circular shape because the bending moment in the span direction is distributed by the lift force of the compressed air tube and the wings at both ears. Therefore, the effective wing area is smaller than the actual wing area, and when the tube is enlarged, the diameter of the tube is increased, thereby degrading the aerodynamic performance of the wing. Therefore, it is necessary to combine these advantages.

Combined rigid frame to ram air wing or composite frame that inserts rigid frame bearing span moment and code direction bending moment in one layer of canopy wing in the way that is frequently used in hang glider solves most of the above problems. However, when the size of the rigid frame is large, there is a problem associated with management and transportation during non-operation. Frames can be folded in two- or three-stage folding umbrellas, or lighter, lighter, and inflated to facilitate the automation or mechanization of the defendant.

In Fig. 14-1, the rigid structure (cantilever beam) is a stress applied to the cross section of the member in response to the bending moment, and compressive force is applied below and tensile force is applied above. Figure 14-2 illustrates the stress on the bending moment on the air tube beam, which is an inflated structure. Supports the bending moment to the limit of the tensile force that the skin of the upper part of the air tube bears, so long as the compressive force applied to the lower part of the air tube beam does not exceed the internal pressure of the air tube. It is strictly the ultimate tensile strength per unit area multiplied by the actual area and ultimately the ultimate tension per unit thickness multiplied by the actual thickness. Therefore, in order to increase the bending moment strength without increasing the diameter of the air tube, the fabric is reinforced with carbon fiber or Dinima fabric that is stronger than the raw material (e.g. Ripstop Nylon) in the longitudinal direction of the beam along the top of the air tube circumference. Alternatively, the reinforcing tape is bonded after processing, or the same material or thick cloth as the raw material is used, or the reinforcing tape of the same material is bonded after processing. In order to increase the bending moment strength of the air tube beam with the reinforcement member 44 in the enlarged circle of Fig. 15, the skin of the upper part of the air tube beam, which is mainly subjected to the tensile force due to the bending moment, is made of the same material. Reinforce with fabric of different material which is bigger.

Since electricity has been put into practical use, power transmission through electric wires has become commonplace, but in the case of power generation using natural forces, large-capacity power storage means (e.g. batteries) are not yet economical as a countermeasure against supply timing and demand timing. When storing energy with water pumped up from compressed air or pumping dam, rotary pumps such as pneumatic pumps or hydraulic pumps and axial pumps are used to transfer the pressurized fluid through internal pressure hoses, rather than direct power generation. It may be desirable to.

It is common to transmit power through wires in three-phase or single-phase exchange.However, in remote areas where a power line network is not established, single-phase or direct current is transmitted by two or single wires or wireless power transmission. This may be desirable. Wireless power transmission shoots a microwave beam and receives DC power with a rectenna ( rec tifying an tenna ). In single-line power transmission, the pole with single-phase alternating current or direct current power is transmitted by one conductor wire, and the other pole is grounded to ground or seawater (eg UP0593138). If the generator is in a fixed position, erect a conventional cable pole and allow the wire to hang over the wire poles through the insulator. Moving power generators use a cord reel, but for fast-moving power generators it is necessary to alleviate the overwhelming task. In order to maintain a constant distance between the generators, it is necessary to synchronize the speed change of each generator or to make the speed of the generator moving all the time uniform. In order to synchronize the speed change, the flight timing of the transverse sections and the transverse sections is synchronized between the respective generators so as to perform the flight operation. In order to make the driving speed of the generator regular, the spare power can be stored and supplemented in the section where the speed drops, or it can be supplemented by the power support from the generator in the section with the spare power. By controlling the pitch of the aberration, it can act as a propeller, and in the case of a fixed pitch aberration, use a separate propeller. Unlike fossil fuel engines, most generators and pumps act as motors when powered back. By sharing the spare power among the power produced by each power converter, the running speed of each power converter can be kept constant while omitting or reducing the energy storage device.

Mechanism driven by flow force (sail, kite, underwater) to increase the economics of converting natural forces such as wind, river water, and seaweed, which have low flow rate or low fluid density, into mechanical drive energy or electricity. The linear motion of the kite, etc. is transmitted to a mechanical link such as a string, push rod, lever, or mast to drive the rotating part of the fixed power converter, or the linear motion is transmitted to the power converter so that the power converter As the relative motion with respect to the ground or the ground causes the rotation of the motion conversion mechanism attached to the power converter to drive the power converter. Since the linear motion of the power converter cannot continue indefinitely, the reciprocating motion or the closed loop circular infinite or eight-way trajectory is drawn. Since the mechanism driven by the flow force is driven along the flow of the fluid (the drag mode) unless the action is taken otherwise, it must be driven in the direction of the flow across the flow of the fluid (lift mode) and the reciprocating or circular trajectory or Proceed along a pre-made trajectory or means for adjusting the direction of travel of the power converter (e.g. steering) to draw the 8-way trajectory.

In addition to rivers, algae and wind are dominant in the horizontal direction. If the axis of the orbit is horizontal, the device moving along the closed loop can continuously cross the flow of fluid. However, horizontal closed loops are usually expensive to install. In the case of a vertical axis circuit, an open circuit is configured to induce a reciprocating motion, or a closed circuit is required, but a preparation for a section that opposes or follows a fluid flow is required. In order to go back in time, the means of relying on a different power source or the free power (kinetic energy) in the cross section can be used for non-kinetic energy (elasticity, position, power, electrochemistry, pressure, etc.) or kinetic energy (e.g. flywheel). Reserve it for use as the inertial energy of the carrier). If multiple power converters are operated, the extra power from the power converter in the section across the flow of fluid can be supplemented by the power converter in the section crossing or following the flow of the fluid.

Figures 16-1 and 16-2 show two sails 46, two or four hydrofoils 47, horizontal axles and rotary generators, with the wind relative to water in the direction of the symbol (45). (48), two rows of wires (49), a power converter consisting of masts, strings and beams that connect them mechanically. The hydrofoil shown in Figure 16-1 is connected to the beam and ball socket structure 50 to have three degrees of freedom. One gimbal instead of a ball socket has one degree of freedom, and two gimbals have two degrees of freedom. The hydrofoil shown in Figure 16-2 has tension and equilibrium in the traction line, leading to a bridle line 51 connected to the traction line, and having five degrees of freedom. In order for the hydrofoil to act as a hapa to maintain a given degree of freedom and to remain stable to external disturbances, the hydrofoil itself has a static stability, or an operation command on the control surface to maintain a stable state by reading a state variable from the sensor. From the control unit. Even if there is a control device, it is common to make the hapa have static stability in case of breakage or failure of the control device. The form in which the mechanism driven by the flow force has a static stability to the posture itself is clearly described in Wright Brother's Flying Machine UP821393.

Figures 17-1 and 17-2 show that externally disturbing or power-transformers are in equilibrium with a statically stable mechanism driven by a fluid flow force, constrained by a bridle string connected to the tow line, and positive tension on the tow line. If the hydrofoil 47 moves up and down from the check according to the change of state, the surface sliding wing 35 or float tries to stay on the water surface, so there is a change in the angle of attack to offset it in proportion to the up and down movement, thus maintaining a certain depth. do.

Fig. 18-1 shows a hydrofoil 47 for controlling posture by manipulating the length of a control surface (not shown) and a leash by a servomotor (not shown) driven by a remote control, a horizontal axle and a rotary generator 48, It is in operation as a power converter unit consisting of one line of wires 49, a kite 53 for posture control by adjusting the length of a bridle line by a servomotor driven by remote control, and a tow line 54 connecting them. to be.

Figure 18-2 shows that the kite is waiting on the water with its tow-line wound (not shown). Figure 18-3 shows that the kite is suspended in the air by a lighter device (filled with hydrogen or helium) 55 than the air. Auxiliary stimulants, such as the balloon or airship, are helpful when there is no wind or when they are weak, but when the kite rises to a high altitude, devices for adapting the pressure difference are likely to be burdened. Detachable and adjustable straps should be used to connect the auxiliary buoyant material.

Power conversion systems operating at sea or in rivers are preferred to have a frame that is folded and bloomed for maintenance, wind-free or harmless algae, soaked with a flexible material, or floated or hulled with a swollen structure, such as a rubber boat. .

Figure 19 shows a cable 56 or rail laid in the air in a mountain valley, with the generator 48 suspended through a pulley, driven by wind 45 and the kitty (Kytoon = Kit e + Ball oon ) and kite ( 53 is towed by the power generation, the power is transmitted through the wire (not shown).

Figure 20 shows that the coupling mechanism box 59 attached to the chain for the track of the open circuit consisting of the chain 57 and the sprocket wheel 58 reciprocates by the flow force of the wind 45 by the wing sail 60 In turn, a generator connected to the sprocket wheel produces electricity in rotational motion. Wing sail (60) has a rotating shaft in the 25% portion of the cord is free yawing 61 around the mast attached to the coupling mechanism (59). The wing sail is fixedly equipped with a jig 62 which provides two stable positions and the rest of the unstable positions, and a boom 63 and a vertical wing connected to a pitchable gimbal (rotating up and down on a horizontal line). The control surface 64 was provided. Therefore, the boom 63 is located to be deflected to either the left or the right in the rear direction of the wing sail. In the figure, the boom is located on the right side of the wing sail, whereby the wing sail is yawing forward to the left and the wing sail is driven to the left to move in the direction of the arrow (65). When the wagon and wing sails continue to the left and the boom touches the attachment 66, the boom shifts to the left of the wing sail, the wing sail yawing to the right and the wing sail and wagon move to the left. You get When moving to the left and the boom touches the device (67) is again positioned to the right, the wing sails and wagon moves to the right and repeats the reciprocating motion. In this case, the detection of the turning point of the reciprocating motion was dependent on the externally mounted devices 66 and 67. However, the position of the turning point is determined by comparing its position with the stored position coordinates using a satellite navigation receiver such as GPS. It is a control device composed of a servo device that can change the shape of a wing sail or manipulate a control surface.

Figure 21 shows a three-wing 60 with a jig connected to a pitchable gimbal with a jig providing two stable positions as previously described, mounted on an arm that rotates about an axis of a fixed generator. It is a vertical wind wheel. It is an example of applying the technology of the present invention to the prior art and applying it to a small system. From the windy side (ψ = 0 °) to the windy side (ψ = 180 °) as one reference line, go to the right and start to the left (ψ = 90 °). The point (ψ = 270 °) that proceeds to the left and proceeds to the right is represented by the devices 66 and 67 in conjunction with the wind vane. In a practical implementation, the controller reads the azimuth from the wind, and compares the azimuth from which the vanes rotate about the generator axis from a sensor measuring a rotational angle, such as a potentiometer or encoder, to give the command to manipulate the control plane.

Fig. 22 shows a control panel 64 connected to a boom 63, with a skeleton kite 68 supported by levitation by means of the instrument 55 with two bridles 69 on the connector box 59. It is bound. The coupling mechanism box 59 is attached to the chain, and the chain 57 constitutes a closed circuit having a horizontal axis as in the wind 45 direction. Running along a track of a closed loop with a horizontal axis allows continuous traversal of the wind, allowing several to run on a single track.

 Figure 23 shows that the kitoon and the kite 53 are constrained by the wagon 70 and are driven by the wind 45, and the wagon 70 drives the generator and motor 72 fixed through the tow line 71. do. If the kite 53 omits the cart and tow the tow line 71 directly, the kite is driven along the wind, and as a result, the relative wind speed is less than 1/2 of the wind speed. However, the movement confined by the cart can have a relative wind speed of up to 2-3 times the wind speed. Therefore, the energy productivity is 64 to 216 times higher than when the cart is omitted.

Figure 24-1 consists of a wheel 75 with a mast 73 and a wing sail 74 steering, a generator linked to the wheel (not shown in the wagon), an electric wire 76 and rotating on the mast. It is a power inverter unit that adds a wagon to disperse the moment, and Fig. 24-2 shows that several power inverter units constitute a flight formation and are driven by wind (45). However, by maintaining a certain distance between each unit to reduce the work of wire take-up.

The reciprocating system is easy to manage, but to increase energy productivity, each power converter shares the power produced, allowing each power converter to draw an eight-way trajectory while maintaining the movement speed. When viewed from above, these systems appear to be sinusoidal, as seen in ribbon dance or waves.
