(57) Abstract
An energy conversion system for converting between one form of input energy selected from a mechanical energy and electrical energy, and an output energy selected from a mechanical energy and electrical energy using a linearly displaced magnetic component interacting with an orbitally displaced magnetic component.
ROTATIONAL KINETIC ENERGY CONVERSION SYSTEM
FIELD OF THE INVENTION
This disclosure generally relates to energy conversion systems with the ability to enter either mechanical and / or electrical energy and emit electrical and / or mechanical energy. In particular, the energy conversion system is adapted to convert a form of input energy selected from mechanical energy and electrical energy to output energy selected from mechanical energy and electrical energy using an orbiting magnetic component and a reciprocating magnetic component, where the mechanical energy of the orbiting magnetic component is associated with a moving fluid.
SUMMARY OF THE INVENTION
A rotational kinetic energy conversion system is provided to convert between kinetic energy and electrical energy, wherein an orbiting magnetic component cyclically interacts with a reciprocating magnetic component, such as a magnetic piston, to transfer energy therebetween.
An exemplary system comprises a reciprocating magnetic piston along a first axis, such as a first longitudinal axis, relative to a longitudinal frame, and a drive magnet orbiting about a second longitudinal axis, to move cyclically to and away of the magnetic piston. In particular, the magnetic piston may be associated with a fixed longitudinal frame defining the first longitudinal axis, and the drive magnet may be associated with a rotating frame defining and rotating about the second longitudinal axis. The interaction of the magnetic piston and the drive magnet can be used to translate between reciprocating kinetic energy associated with the movement of the piston and rotational kinetic energy associated with the movement of the rotating frame and the drive magnet.
The first and second longitudinal axes may be arranged perpendicular to each other. The first and second longitudinal axes may not cross. The drive magnet can be displaced axially relative to the second longitudinal axis from the magnetic piston so that the orbital path of the drive magnet prevents the drive magnet from touching the magnetic piston and cyclically brings the drive magnet close and far from the piston magnetic.
Alternatively, the first longitudinal axis may be coplanar with the orbital path of the drive magnet with the magnetic piston located radially out of the orbital path.
Two or more magnetic pistons may be positioned circumferentially around the second longitudinal axis to cyclically interact with the drive magnet at different angular positions of the drive magnet in its orbital path around the second longitudinal axis. Two drive magnets can be provided that have orbital paths at different locations along with the second longitudinal axis, such as to cyclically drive the drive magnets into magnetic interaction with opposite sides of the magnetic piston. Two magnetic pistons can be provided on opposite sides of the orbital path of a drive magnet to cyclically interact with both drive magnets. Similarly, a plurality of magnetic pistons and drive magnets can be provided at various locations around and along the second longitudinal axis to create a multi-stage rotational kinetic energy conversion device.
The magnetic piston may be associated with a longitudinal frame and constrained by the longitudinal frame to reciprocate along the first longitudinal axis. In particular, the longitudinal frame can be a chamber that encloses the magnetic piston, defining the first longitudinal axis, and restricting the magnetic piston so that it does not move far from the first longitudinal axis. Alternatively, the longitudinal frame may be a shaft defining the first longitudinal axis and the magnetic piston may be positioned around the shaft constrained by the shaft so that it does not move away from the longitudinal axis. Additionally or alternatively, the magnetic piston may be restricted to reciprocate along the first longitudinal axis by one or more magnets placed in fixed positions relative to the longitudinal frame. The magnetic piston can be associated with a winding or coil placed around the first longitudinal axis to convert the energy between the kinetic energy with the movement of the magnetic piston and electrical energy associated with the current flowing through the winding or coil. The longitudinal frame may include a housing that encloses components associated with the magnetic piston.
The magnet . The actuator may be attached to a rotating frame about the second longitudinal axis. The frame may utilize blades, a propeller, or any variant based on airfoil using a horizontal or vertical axis of rotation, a water wheel, a fan, a rotary pump, or a rotary compressor, or any other rotational device with the ability to convert between the kinetic energy of a moving fluid and the rotational kinetic energy of a rotating frame. Alternatively, the frame may be associated with a rotational kinetic energy conversion device such as a rotary electric motor or generator, a rotary pump, or a rotary compressor.
The drive magnet can be tangentially biased relative to its orbital path around the second longitudinal axis to present a first pole to the magnetic piston as it approaches the magnetic piston and a second pole to the magnetic piston as it retracts from the magnetic piston. The magnetic piston may have a radial bias component relative to the first longitudinal axis to present substantially the same magnetic pole to the drive magnet as the drive magnet approaches the magnetic piston and as it moves away from the magnetic piston.
The magnetic piston may have an axial bias component relative to the first longitudinal axis to interact with the axial end magnets at fixed positions at opposite ends of the longitudinal path of the magnetic piston to limit movement of the magnetic piston and to act to reset the magnetic piston to the center of its longitudinal path.
In an exemplary configuration, one or more rotational kinetic energy conversion devices are placed in proximity to one or more linear kinetic energy conversion devices with the magnetic fields aligned such that the polarity of the drive magnet is the same as the polarity. from the opposite face of the piston as the drive magnet rotates towards the piston. As the drive magnets rotate toward the piston, the drive magnetic field interacts with the moving piston's magnetic field to push the piston toward a fixed-end magnet. After the drive magnet passes the piston, the opposite axial fields of the fixed-end magnet and the piston interact, and the piston is accelerated by the fixed-end magnet in the opposite direction. At the same time that the piston is being accelerated by the drive magnet in a certain direction, the piston approaches an end magnet which increasingly exerts a force on the piston to encourage the piston and ultimately reverse its direction of movement. . This process is repeated continuously, resulting in an oscillation of the piston within a winding that generates electrical energy. The piston can be displaced at multiples of the magnetic drive frequency.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, the exemplary energy conversion devices are shown in detail. Although the drawings represent alternative configurations of power conversion devices, the drawings are not necessarily to scale and some features may be exaggerated to provide a better illustration and explanation of a configuration. The settings set forth herein are not intended to be exhaustive or otherwise limit the device to the precise forms disclosed in the following detailed description.
Referring to Figures 1 and 2 which schematically illustrate a generalized rotational kinetic energy conversion system 10, the general arrangement of the mechanical, magnetic and electromagnetic components of the energy conversion system 10 will be described. In particular, Figures 1 and 2 provide a schematic representation of the exemplary rotational kinetic energy conversion system 10 having an exemplary linear kinetic energy conversion device 100 and an exemplary rotational kinetic energy conversion device 200. The conversion devices Exemplary rotational kinetic energy and alternative kinetic energy are illustrated in other figures and described hereinafter.
Continuing with reference to Figures 1 and 2, the linear kinetic energy conversion device 100 has a fixed frame 104, which defines a first longitudinal axis 108 (see Figure 1). A complex magnetic piston
110 it is restricted by mechanical and / or magnetic means, to be reciprocating along the first longitudinal axis
108 around the central position in which it is illustrated.
Fixed frame 104 may include a housing 112 surrounding piston 110, as well as axial end magnets 114 (see figure
2) and / or radial side magnets 116 (see Figure 2) with the ability to interact with piston 110, as will be described hereinafter, to position piston 110 within housing 112. Additional configuration details and alternative configurations for the fixed frame 104 they will be described hereinafter. The fixed frame
104 it can be provided with a toroidal coil or winding 120 with the ability to interact with complex magnetic piston 110 to generate an electric current in the winding in response to oscillation of the magnetic piston along first longitudinal axis 108.
Rotational kinetic energy conversion device 200 has a rotating frame 204 mounted, for example to a stem 202 defining a second longitudinal axis
208 (see figure 2) around which the rotating frame
204 is restricted to rotate. The rotating frame 204 can be powered by hydrolysis, wind, or solar energy. The hydrolysis energy can be exploited using a river current or the action of the waves of lakes and oceans, such as using the systems illustrated in Figures 10 to 13 and described hereinafter.
Wind energy can be exploited using a squirrel cage, propeller or blade design, or cups, as variously illustrated in Figures 14 to 16 and described below. Solar power can be used as a supplemental power supply as a backup, to power control systems, or to selectively operate optional additional windings when the wind is less than optimal, as described hereinafter.
Rotating frame 204 can include one or more wheels 206, as shown in Figure 2, which extend to locations adjacent to linear kinetic energy conversion device 100. One or more drive magnets 210 are attached to portions of the rotary frame 204 away from the second longitudinal axis 208, and define circular orbital paths 212 (see Figure 1) around the longitudinal axis 208 when the rotary frame 204 is rotated about it. As shown in Figure 2, the rotating frame 204 can be provided with two drive magnets 210, one generally positioned on each side of the linear kinetic energy conversion device 100 to engage opposite sides thereof. Providing opposing drive magnets 210 provides a balanced force on the piston 110, and thus reduces potential friction between the piston 110 and the components of the fixed frame 104.
Additional drive magnets can be provided 20 at different angular positions around the second longitudinal axis to also selectively interact with piston 110. It will be appreciated that components can be dimensionally scaled and in magnetic force and weight to provide smooth reciprocation or oscillation of the piston
110 for the expected range of rotational speeds of the rotary frame 204. The oscillation frequency of the piston
110 it may be the same as or greater than the rotational frequency of the magnet 210 or magnets.
Rotating frame 204 can be rotated by a moving fluid, such as air or water, through the use of blades, or similar devices, described below, in order to capture the kinetic energy of the moving fluid. In addition it will be appreciated that the fixed frame
104 it can be fixed in position relative to the second longitudinal axis 208 and the rotary frame 204 through any convenient means. The support structure for devices 100 and 200 has been omitted from Figures 1 and 2 to provide clearer visibility of the components of these devices. In use, as rotating frame 204 rotates, drive magnets 210 orbit second longitudinal axis 208 in and out of range of complex magnetic piston 110 to cyclically interact with complex magnetic piston and cause oscillation of piston 110 relative to the fixed frame 104.
This oscillation of the piston 110 generates a current in the toroidal winding 120, thus allowing the rotational kinetic energy conversion system 10 to convert the kinetic energy of a moving fluid into rotational kinetic energy of the rotary frame 204, then into linear kinetic energy of the piston 110 and finally electrical energy in the form of electric current through toroidal winding 120.
The efficiency of the conversion of the kinetic energy of the moving fluid into electrical energy will depend on the efficiency of the energy transfer from one stage to the next stage in the rotational kinetic energy conversion system 10. This can be advanced by choosing the appropriate lightweight materials for all components, as well as scaling the magnetic components and choosing their relative polar orientations to optimize efficient system operation.
10. Therefore, it is contemplated that all of the magnets used in the energy conversion system 10 may be rare earth magnets, such as neodymium magnets to provide the desired strength combined with low weight.
Therefore, it is contemplated that the complex magnetic piston 110 be manufactured or selected to have an axial magnetic component and a radial magnetic component. The axial magnetic component can interact with the axial end magnets 114 to limit the movement of the piston 110 and to accelerate the piston 110 to return to its central position in the fixed frame 104, while the radial magnetic component can interact with the winding toroidal 120 to generate electric current. The axial magnetic component is also used to interact with drive magnets 210. The radial magnetic component can also interact with the radial side magnets
116 to help position the piston and reduce friction.
Therefore, as shown in FIG. 1, the complex magnetic piston 110 can be manufactured or selected to effectively present axial poles of identical polarity to the respective faces presented by the axial end magnets 114, as well as to present effectively radial poles of identical polarity to that presented by the radial side magnets 116. In addition, drive magnets 210 can be selected and oriented, as shown in FIG. 1, to effectively present a face of polarity identical to the radial magnetic component of piston 110 as the drive magnets approach the piston and to effectively present a face of polarity identical to the radial magnetic component of piston 110 as the Drive magnets pass and move away from the piston along their orbital paths. More particularly, as the drive magnet 210 moves toward the piston 110, the interacting faces of the piston 110 and the drive magnet 210 repel each other, causing the drive magnet 210 to impart a force on the piston 110 moving it towards an end magnet. When the drive magnet 210 passes the piston
110, the opposite faces of the piston 110 and the drive magnet 210 begin to interact and the piston 110 is pushed in the opposite direction. End magnets 114 also act on the piston to encourage and eventually reverse its direction of movement.
It will be appreciated that opposite polarities can be replaced by identical polarities in the above-described configurations for many applications such that magnet 210 attracts piston 110 and accelerates it to the axial end magnet, as long as each of the polarities is selected from so that the forces balance to produce the desired action of the piston 110.
This complex magnetic design for the complex magnetic piston 110 can be provided by, for example, constructing the piston from two concentrically placed magnets, one being axially magnetized and one being radially magnetized, to provide a complex field.
This alternatively can be provided as shown in Figure 3, constructing the complex magnetic piston 110 from a plurality of individually manufactured magnetic segments 122a-122h and then encased in a ring
124, as shown, or held together by an epoxy material. Ring 124 may be comprised of aluminum and have an outer cylindrical wall 132 and at least one annular wall 134 for engagement of the magnetic sections. The annular wall 134 may have a centrally located opening 136 for use in mounting the complex magnet 110 to other components, such as a stem, when required for some applications.
The complex magnetic piston 110 may be a radial neodymium ring magnet of the type sold by Engineered
Concepts, 1836 Canyon Road, Vestavia Hills, AL 35216, owned by George Mizzell in Birmingham, Alabama, and offered for sale under the name SuperMagnetMan, for example, as part number RR0060N, RR0090N, or RR0100S. Applicants have experimentally determined that such magnets have the property of having an axial magnetic component to effectively present a north pole on one face 126 and a south pole on an opposite face not shown, while also having a component radial having a first pole, such as a north pole on the first curved face 12 8, and an opposite pole, such as a south pole, on a second curved face surface 130.
For example, an acceptable complex piston 110 has been manufactured using eight separate N42 grade diametric magnet segments. For some applications, a weaker complex piston made of N40 grade or N32 grade diametric magnetic segments may be desirable because it is easier to assemble using weaker magnet segments. It has been experimentally suggested that such variables as the Gauss force, force and length of the magnetic field of the piston 110, as well as the speed (oscillations) of the radial magnet can be maximized. The addition of a second radial magnet also appears to be experimentally useful. However, from experiments to date, it seems that the most important variables to maximize are the Gauss force and the radial magnetic force, and therefore a piston made of an N52 grade magnet may be desirable.
Additional details and alternatives for a linear kinetic energy conversion device 100 'are shown in Figures 4 through 6. Fixed frame 104 of device 100' includes an inner tube or casing 140 formed of a suitable non-conductive material, such as plastic , supporting a toroidal winding 120 (see Figures 4 and 5) around it and a pair of axial end magnets 114 (see Figures 4 and 6) at each end of the inner casing 140.
It should be noted that a second winding can be employed, which when selectively energized, temporarily destabilizes the balance of forces acting on piston 110 in order to initiate or assist in the oscillation of piston 110. It will be appreciated that the oscillation of the Piston 110 may additionally or alternatively be initiated or assisted by mechanical action causing piston 110 to move relative to the other magnetic components.
Alternatively, a plurality of toroidal windings 120 may be provided. One or more passive toroidal windings may be provided to create an output current as a function of piston movement. One or more active toroidal windings can be provided to create a magnetic field opposite to the magnetic field of the piston. The passive toroidal winding 120 is significantly larger than the active toroidal winding. A passive winding can be operated by solar energy when the wind is less than optimal. The energy created by the piston that interacts with the passive toroidal winding can be transferred to, and stored in an electrical device such as a battery or capacitor. The active toroidal winding, not shown, can use the electrical energy previously created by the moving piston magnets interacting with the passive toroidal winding.
Inner casing 140 defines a channel 144 for piston 110. Toroidal winding 120 may be dimensioned as shown to extend only partially toward the ends of inner casing 140 to provide a gap of more than the thickness of piston 110 such that the field breaks as the piston approaches the end magnets 114, causing an electrical spike in the current generated in the toroidal winding 120.
The fixed frame 104 may further include an outer casing 142 enclosing the inner casing 140, the toroidal winding 120, and the end magnets 114. The outer casing 142 may include a cylindrical wall 148 closed at each end by a wall 150 (see figure 4) to form an enclosure for the magnetic components of the kinetic energy conversion device 100 '. Axial end magnets 114 can be attached to, or hit walls 150. It should be noted that in Figures 4-6, the piston 110 is shown separate from the inner casing 140 to avoid energy loss for friction between components. However, piston 110 may be provided with a diameter large enough relative to the inside diameter of toroidal winding 120 to restrict air flow between the sides of piston 110. To prevent air pressure build-up on either side of piston 110 from inhibiting piston movement
120, the housing 112 can be provided with the openings
146 (see Figures 4 and 6) allowing air flow to the respective sides of the piston 110. The openings 146 can also provide some cooling of the internal components of the linear kinetic energy conversion device 100 '.
As shown in Figure 4, cables 154 (see Figure 4) for taking power from toroidal winding 120 extend through openings 156 in cylindrical wall 148 to an electrical load 160, such as an external powered device, an energy grid, or an energy storage device. Cables 162 to connect toroidal winding 120 to a power source
164, selectively operated by a switch 166, automatically activated, such as by a microprocessor, or manually activated, can be provided when it is desired to introduce a temporary magnetic imbalance to the piston 110 to initiate piston oscillation for applications where priming is required. The microprocessor can be operated by solar energy when the wind is less than optimal. Alternatively, cables 154 and 162 can be replaced by a wireless power transmission system.
The linear energy conversion device 100 'may be configured to provide either an alternating current or direct current output. Electric charge
160 It may be one or more electrical devices with the capacity to consume energy, one or more storage devices used to store energy for later use, or a power distribution system.
Exemplary storage devices for electric charge 160 include batteries, compensating circuits, capacitors, and other devices with the capacity to store energy using electrical, chemical, thermal, or mechanical storage systems. Exemplary electrical devices for electric charging 160 include electric motors, fuel cells, hydrolysis conversion devices, battery charging devices, lights, and heating elements. The electrical load of the exemplary power distribution system 160 includes a residential circuit breaker panel, or an electric power grid. Electric charge 160 may also include an intermediate electrical energy conversion device or devices with the ability to convert energy into a form usable by electric charge 160 such as an inverter.
Although the power source 164 and electric charge 160 are illustrated schematically as independent of the linear kinetic energy conversion device 100 ', either or both may be integrated with a linear kinetic energy conversion device 100' or connected to the 100 'linear kinetic energy conversion in some way.
In particular, one or both may alternatively be attached to the outer shell 142 or mounted within a compartment formed in the outer shell 142. Furthermore, although the power source 164 and the electrical load 160 are illustrated schematically as being tangentially located relative to the first longitudinal axis 108, either or both may be conveniently located along the longitudinal axis 108 for some implementations.
In this way, for example, although not illustrated, the outer shell 142 can extend beyond one of the end magnets 114 to provide a compartment for storing a power source 164 or electrical charge.
160 such as batteries, a radio, or a light. Additionally or alternatively, a removable cover, not shown, may be provided at one end of the outer shell
142 with a compartment or connecting feature for a power source or electrical charge or for replacement of its components. The radio or light can be operated on solar power, batteries, or power from a power grid when the wind is less than optimal.
Outer casing 142 may be provided with appropriate legs or mounting points to selectively mount linear kinetic energy conversion device 100 'on a stationary structure, such as a tower for a rotary wheel based on airfoil.
It should be noted that the exemplary linear energy conversion device 100 'does not include a radial magnetic source such as the radial side magnets 116 shown in Figures 1 and 2, since its use is optional depending on the application.
Referring now to Figures 7 to 9, another exemplary linear kinetic energy conversion device 100 is illustrated. Device 100 is similar to device 100 'except as described below.

100, the complex magnetic piston 110 is positioned outside a toroidal winding 12 0 and a pair of ring-shaped axial end magnets 114 (see Figures 7 and 9) is provided to act on the complex magnetic piston
110 .
Having previously described alternative examples of the linear kinetic energy conversion device 100, attention is now drawn to Figures 10-16 illustrating alternative examples of the rotational kinetic energy conversion device 200.
A first exemplary rotational kinetic energy conversion device 200 'is illustrated in Figures 10 through 12 using a rotary wheel 220 to convert the flowing kinetic energy of water to rotational kinetic energy. In particular, rotary wheel 220 has two separate disc-shaped walls 222 mounted to a shaft
224 and a plurality of fluid resistant surfaces, such as vanes, blades, or vanes 226 extending between walls 222 radially from shaft 224. When rotary wheel 220 is partially submerged in moving water, water will act on vanes 226 to cause rotation of the water wheel. The drive magnets 228a may be mounted to the face of each blade. Alternatively, the drive magnets 228b (see Figures 11 and 12) may be mounted on one side of one of the walls 222. A linear kinetic energy device
100 it can be mounted in a fixed position adjacent to one of the walls 222. As shown in Figure 11, as the water wheel 220 rotates, the drive magnets 228a and 228b interact with the piston 110 in the linear kinetic energy 100 in the manner previously described to generate electrical energy. As shown, the linear kinetic energy device
100 It can be mounted between two adjacent water wheels 5 220 and receive power from both wheels.
An alternative exemplary rotational kinetic energy conversion device 200 is illustrated in FIG.
13. Device 200 is similar to device 200 except as described below. In particular, the kinetic energy conversion device 200 has a rotating wheel 220 designed to interact with a linear kinetic energy device 100 positioned in the same plane as the rotating wheel. In this case, then, drive magnets 228c may be located at the edges of blades 226. An additional rotary wheel, not shown, may be provided flat with the illustrated rotary wheel on the other side of the linear kinetic energy device 100. The wind may also drive this rotary wheel.
Another alternative exemplary rotational kinetic energy conversion device 200 '' 'is illustrated in Figures 14 and 15. Device 200' '' comprises a post 232, in turn mounted to the fluid resistance device
238, and attached, for example, to a building 234. The device has a rotary frame 23 rotatably mounted to the pole
232. The device 200 '' 'has a plurality of blades, eg, cups 23 8, mounted at the ends of the arms 240 extending radially from the post 232. A pair of linear kinetic energy devices 100 are fixedly mounted to the post 232 adjacent to rotating frame 236 at opposite radial locations around the post. As shown in Figure 15, a plurality of drive magnets 242 are mounted to arms 240 so as to cyclically sweep through linear kinetic energy device 100 and thus interact with the piston
110 in the linear kinetic energy device 100 in the manner previously described to generate electrical energy.
Another alternative exemplary rotational kinetic energy conversion device 200 is illustrated in FIG.
16. Device 200 comprises a wind resistance blade 250 mounted to a shaft 252 that extends generally perpendicular from a vertical pole 254, which in turn can be mounted to the ground.
Device 200 has a plurality of blades or blades 256 mounted at the ends of arms 258 extending radially from shaft 252. As shown in Figure 16, arms 258 may be cylindrical rods. Alternatively, arms 258 may be shaped to capture a portion of the wind, such as being shaped like propellers or turbine blades or any airfoil configuration. Three linear kinetic energy devices 100 are fixedly mounted to pole 254 at separate curved locations around shaft 252. A plurality of drive magnets 260 are mounted to arms 258 for cyclical sweeping by linear kinetic energy device 100 and so on. interact with piston 110 in linear kinetic energy device 100 in the manner previously described to generate electrical energy.
Referring now to Figures 17 and 18, alternative rotational kinetic energy conversion systems 10 ', 10' 'and 10' '' are illustrated, respectively, where multiple linear kinetic energy conversion devices 100 and conversion devices of Rotational kinetic energy 200 are used to capture the energy of a moving fluid.
In the 10 'and 10 rotational kinetic energy conversion systems, shown in Figures 17 and 18, respectively, the linear kinetic energy devices
100 and rotational kinetic energy devices 200 are alternated such that linear devices obtain energy from two adjacent rotational devices and rotational devices provide energy to two adjacent linear devices. In the rotational kinetic energy conversion system 10 ', the rotational devices are coaxial, while in the rotational kinetic energy conversion system 10, the rotational devices have the parallel axis and the linear devices are copied to the rotational devices. The choice between these orientations may depend on the nature and direction of the fluid flow and the geometry of the space available for mounting the system.
In rotational kinetic energy conversion systems 10 '' ', as shown in Figure 19, each linear kinetic energy device 100 is positioned between a pair of rotational kinetic energy devices
200, but comprises an independently rotating subsystem around a shaft 280.
Therefore, it will be appreciated that an energy conversion system can be configured as a single stage, as shown in Figures 1 to 16, multiple independent stages, as shown in Figures 17 and
19, or as coupled multiple stages, as shown in Figure 18. When built with multiple stages, the individual stages may share components, such as outer or inner housings or electrical devices.
Multiple linear energy conversion devices of one or more stages may be electrically or mechanically connected in parallel or in series or operate independently.
It will be understood that the above description is intended to be illustrative and not restrictive. Many different configurations and applications than the examples provided would be apparent to those skilled in the art upon reading the above description.
For example, although in the exemplary structures described above, rotational kinetic energy conversion device 200 received energy from a moving fluid, and linear kinetic energy conversion device 100 received that energy and converted it to electrical energy, the components of the rotational kinetic energy conversion system 100 can be modified to provide an alternative category of energy inputs or outputs for any of the devices 100 and 200. For example, the linear kinetic energy device 100 could be energized, so that the toroidal winding 120 drives a piston 110 to interact with the drive magnets in a rotating frame to drive a fan. Power conversion devices 100 and
200 They can alternatively be used as a generator, motor, pump, compressor, motor, or electric power transformer.
The relative movement between the piston 110 and the toroidal winding 120 can be caused by any mechanical action such as a wind, hydrolysis (wave, current or vertical drop energy) input, or mechanical from moving or oscillating objects. Alternatively, the energy conversion device can transmit power to a device or devices with the ability to use the electrical output of the toroid without using intermediate storage. These devices include, but are not limited to, electric motors, fuel cells, hydrolysis conversion devices, battery charging devices, lights, and heating elements. Alternatively, the piston can be directly displaced by a fluid acting directly on one face of the piston, such as moving air or water, a fuel that expands against a face of the piston, or a fluid that expands or contracts in response to a change in temperature.
It will be appreciated that the energy storage device described above may be acting in conjunction with and providing an input, either primary or secondary, to an individually circuited system such as a residential home fuse panel powered by a commercial energy grid or a hydrolysis grid, nuclear, wind, solar, swell or any other type of electric power generation grid as used for public and / or private energy consumption. The device can be a single entity or multiple entities combined as serial, parallel, or independently units to provide increased output.
The device may have the ability to act in conjunction with an electrical device that has the ability to calculate and regulate input power to the active toroid so that piston movement is maintained. The device can, acting in conjunction with an electrical device with the ability to calculate and regulate input power to the active toroidal winding, for example, an electronic control module with the ability to be programmed, reading input signals and generating input signals. output based on input signals so that piston movement is slowed down, stopped, and reversed with minimal input power to the active toroidal winding.
Control algorithms can be provided with the ability to derive the deceleration and acceleration of the piston and calculate the required toroidal energy needed to accelerate the piston to its required speed and generate a current and voltage input signal for the active toroidal winding. The algorithm would minimally require consistent input signals of piston displacement to three different positions, for example, using Hall effect sensors, each detected position is passing the piston median displacement point along the longitudinal axis towards a horizontal magnet , calculating the time between the three impulses to derive the speed and deceleration for two time periods, calculating the deceleration rate as a function of the position of the piston, calculating the point at which the piston will stop, determining the force necessary to accelerate the piston to the desired initial speed, calculating the required toroidal winding force, generating a current command signal (for a fixed voltage) and measuring acceleration as the piston moves in the opposite direction along its longitudinal axis and adjusting the toroidal power level to maintain the required target piston speed at measure the time required to make the journey between the three points.
The power conversion device may be adapted to minimize input power to the active toroidal winding in conjunction with the control algorithms. The control algorithm can maintain the following relationship: F<sub>t</sub>i<sub>n</sub>> F<sub>p</sub>-F<sub>M</sub>h where F<sub>t</sub>i<sub>n</sub> is the active toroidal winding force in a direction opposite to that of the piston force 110 provided to the input voltage and current, F<sub>p</sub> is the force of the piston, and F<sub>Mh</sub> is the horizontal magnet force opposite to the piston force F<sub>p </sub>such that a piston moving along its longitudinal axis is decelerated as it approaches a horizontal magnet, stops instantly, and is then accelerated by toroidal winding 120, at a predetermined rate, empirically developed by force. applied F<sub>t</sub>in, acting in conjunction with the repellent force of the end magnets.
Acting in conjunction with an end magnet, the longitudinal axis of this device, including these magnets, can be oriented from 0-90 degrees relative to a horizontal plane, offset by a finite distance from the vertical midpoint whose primary force fields are oriented 90 degrees of the radial magnets, said magnets located so that their fields interact with the radial magnets along the vertical axis of the radial magnets, in those applications where a radial magnet is provided.
This magnet or magnets can be placed either internal to the stationary radial magnets (as illustrated) or external to the stationary radial magnets, i.e. the magnet has an inner diameter larger than the diameter

described having a linear kinetic energy conversion device with an oscillating magnetic piston surrounded by a toroidal winding which is provided in a fixed location (deviated from the axis of rotation of a rotary wheel having a drive magnet radially positioned so that, at As the wheel is rotatably driven by a moving fluid, the magnet cyclically passes through the piston and causes the piston to oscillate, thus inducing a current in the winding. The wheel may be, for example, a rotating wheel or rotating blades driven by moving water or air. In another exemplary system, a pair of wheels is placed on opposite sides of the linear kinetic energy conversion device, each provided with a drive magnet or multiple magnets to provide a balance of magnetic forces on the piston as the wheels rotate. . In yet another exemplary system, a plurality of angularly spaced drive magnets are provided on one or more wheels. In yet another exemplary system, a plurality of linear kinetic energy conversion devices are fixedly mounted at angularly spaced positions relative to one or more rotating wheels to provide balanced power drawn against the rotating wheel or wheels.
Importantly, the system can be operated efficiently at smaller scales than traditional wind turbines, making them an important power option for homeowners and small businesses.
Additionally, the system can be scaled for larger installations, for example, by making larger linear and rotational kinetic energy devices, coupling multiple stages of the kinetic devices to a single rotational device powered by wind or water, or putting multiple units, each one with a single pole or shaft kinetic energy conversion system.
It will be appreciated that each linear kinetic energy conversion device described above will have an optimal speed range inherent in its design. It is contemplated that a rotational kinetic energy system can be tunable to respond to different moving fluid speeds. For example, the rotary frame 200 that rotates directly by the moving fluid can be connected, via a gear system 290 such as a continuously variable speed transmission, as shown in Figure 20, to a frame or wheel secondary 292 rotating at an optimum speed for the operation of the linear kinetic energy conversion device. The drive magnets 294 can be mounted to the secondary wheel 292 such that the linear kinetic energy conversion device 100 experiences an oscillation at a desired speed. Alternatively, the blades can be rotatable to present a more or less effective surface area for the wind as the wind speed changes. Similarly, the number and arrangement of linear kinetic energy conversion devices associated with a water wheel or windmill can be varied, for example, by providing a mechanism to move the linear kinetic energy devices into or out of the region of the drive magnet.
Alternatively, the shaft or pole that supports the units can be provided with a speed regulation system, such as a clutch or braking system to limit their rotational speed. Such clutch movement, blade turn, gear and / or device systems can be automated and microprocessor driven and can be programmed to either optimize system efficiency or to maximize power output, depending on needs. from the owner. The microprocessor can be operated by solar energy when the wind is less than optimal.
Alternatively, the system may be designed to self-adjust to changing wind conditions.
For example, the cups or blades may be designed to bend in response to a change in wind conditions to provide a non-linear response to increases in wind speed to reduce the effect of gusts of wind or excessive wind. As an example, the cups can face down 1 to 3 or 5 degrees or the propeller aerodynamic surfaces can be designed to create a slight lift so that when they catch the wind and start to turn, they will rise slightly, decreasing friction in the bottom but not creating enough lift to blow it off. The blades can alternatively be designed at various angles, so that the lower turbine is at 1/2 degree, the next one at 1 degree, above that 1.5 degrees or 2 degrees, etc. so that, as they rotate, each blade separates from the upper and lower blades, decreasing friction and decreasing wear while increasing speed.
