SYSTEM FOR GENERATING ELECTRICITY BY USING GRAVITATIONAL MASS AND/OR MOMENTUM OF MOVING VEHICLE
A mechano-electrical energy generation system generates electrical energy from the passage of a vehicle over an inclined ramp assembly. This assembly includes an incline ramp that is rotatable about an axis proximate a vehicle roadway surface, and a safety decline ramp hinged with and rotatable with the incline ramp. The incline ramp is coupled via a roller assembly to a gravity wheel that drives a flywheel coupled to an electrical generator. As a result, passage of the vehicle over the incline ramp rotates the wheel via the roller assembly and drives the flywheel so that the electrical generator outputs electrical energy. When the vehicle exits the safety decline ramp, a counterweight rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their original inclined positions above the roadway surface.
The present application claims the benefit of co-pending U.S. Patent Application Ser. No. 60/642,953, by F. Ghassemi et al, entitled: “Energy Recovery System,” filed Jan. 7, 2005, and the disclosure of which is incorporated herein.
FIELD OF THE INVENTIONThe present invention relates in general to mechano-electrical energy generation systems, and is particularly directed to a ‘kinetic energy/gravity power plant’ (KGPP) method and apparatus for generating electrical energy from the passage of a vehicle over an inclined and rotatable ramp assembly. The ramp assembly includes an incline ramp that is rotatable about an axis proximate a roadway surface on which the vehicle travels, and a safety decline ramp hinged with and rotatable with the incline ramp. The incline ramp is coupled via a roller assembly to a gravity or ‘G’ wheel that drives a flywheel coupled to an electrical generator. As a result, passage of the vehicle over the incline ramp causes the roller assembly to rotate the wheel and reduce inclinations of the incline ramp and the safety decline ramp above the roadway surface. As the incline ramp is rotated downwardly toward the road, it rotates the wheel to drive the flywheel and cause the electrical generator to produce electrical energy. Once the vehicle exits the safety decline ramp, a counterweight coupled to the wheel urges the roller assembly against the bottom surface of the incline ramp, and rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their original inclined positions above the roadway surface.
BACKGROUND OF THE INVENTIONThe consumption of electrical power has undergone a relatively rapid increase in recent years. For example, in the United States and in developed countries, the increase in the application and usage of computers, as well as hybrid/electric cars, has created a demand for more electric power plants. The present invention is considered to fall into the general category of renewable electric power sources, such as, but not limited to, wind-power systems, hydro-electric power systems and solar-power generation systems, and gravity-based power plants, where the source of energy is basically free. In the context of mechano-electric power systems, the gravitational mass and kinetic energy/momentum of moving road vehicles (e.g., automobiles and trucks) constitute a free source of energy, especially on downhill slopes where cars and trucks are urged in the downhill direction by their gravitationally pulled masses. The basic concept involved in kinetic energy/gravitational power plant (KGPP) or kinetic energy/gravitational electricity generation involves the translation of a moving mass that is pulled by gravity into mechanical and rotational motion, which is used to drive a standard electrical generator.
SUMMARY OF THE INVENTIONIn accordance with the present invention, advantage is taken of the components of kinetic energy/gravitational electricity generation; in particular, the kinetic energy/momentum and gravitational mass of a moving vehicle are used to create a linear or semi-linear mechanical motion. This motion, in turn, is translated into rotation, which turns an electrical generator, the output of which is electrical power. More particularly, as described briefly above, the present invention is directed to a mechano-electrical energy generation system for generating electrical energy from the passage of a vehicle over a ramp assembly, that is mechanically biased to be inclined above the roadway as it is approached by a moving vehicle. The ramp assembly includes an incline ramp that is rotatable about an axis proximate a roadway surface on which the vehicle travels, and a safety decline ramp hinged with the incline ramp. The incline ramp is coupled via a roller-bearing assembly to a wheel, such that passage (weight and movement) of a vehicle onto and over the inclined ramp causes the ramp to rotate downwardly, and rotate the wheel in a direction that drives a flywheel coupled to an electrical generator. This action continues until the inclinations of the incline ramp and the safety decline ramp above the roadway surface have decreased such that the ramp assembly is essentially parallel to the roadway surface. Once the vehicle exits the safety decline ramp, a counterweight coupled to the wheel urges the roller assembly against the bottom surface of the incline ramp, and rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their inclined positions above the roadway surface.
BRIEF DESCRIPTION OF THE DRAWINGS
Attention is initially directed to
Coupled to a second location 53 of the wheel, that is preferably generally diametrically opposed to the first location 51 (as shown by the lines 55 and 56), is a counter-weight bearing 70, from which hangs a counter-weight 72. The effect of gravity on the mass of the counter-weight 72 is sufficient to cause the wheel 50 and its associated roller assembly 60 to rotate in a counter-clockwise direction and urge the roller assembly 60 into contact with the bottom surface of the incline ramp 11, and rotate the wheel so as to bring the incline ramp 11, and the safety decline ramp 30 hinged thereto, to their respective inclined positions above the roadway surface in the absence of a vehicle engaging the ramp assembly. The counter-weight 72 comes to rest against a stop 74, so that the ramp assembly cannot move higher than a pre-designated ‘up’ orientation. However, in response to engagement of a vehicle 23 with the incline ramp 11, the counter-weight 72 allows the roller assembly 60 to rotate the wheel 50 (clockwise, as viewed in
From the foregoing description of the various components of the invention, operation of the overall energy conversion system is straightforward. In the following discussion, attention may be directed to the diagrammatic side views of
Repeated engagements with the ramp assembly by additional vehicles will cause an oscillating (clockwise and counter-clockwise) rotation of the wheel 50 which, in turn, results in repeated (clockwise) rotation of the flywheel 80. As noted above, the flywheel's crankshaft is at the center of a free wheel hub mechanism where a ratchet gear system allows only forward (clockwise) rotation of the flywheel. Moreover, as shown in
As shown in
As described in the foregoing, the linear up-down motion of the ramp assembly 10 results in an oscillating rotation of the wheel 50. This oscillating rotation is transferred to flywheel 80 which has a ratchet and freewheeling hub system. The flywheel rotates in clockwise motion which causes the electric generator to spin rapidly and generate electricity. Deterministic calculation of a ramp with an up inclination angle of seven degrees and a height of ten feet shows that a constant flow of trucks on such ramp can produce up to megawatts of power.
Non-limiting examples of locations for installing the mechano-electrical conversion system of the present invention include truck stops, where trucks are forced to slow down, go over possible bumps and then go on a route off of the highway. The best efficiency and most power are generated by installing the system on a downward slope, although it is to be understood that the system may alternatively be installed on a generally horizontal roadway. For example, installing the system at multiple (e.g., ten to twenty) locations as diagrammatically illustrated in
Once a truck driver has slowed down his truck, so that it can go downhill, then, as the truck moves over the ramp assemblies, the incline ramps are sequentially rotated downwardly with it, due to the flatness of the road. Therefore, there is no danger or possibility for the travel of the truck to be diverted by the edge of the ramp assembly unless the ramp assembly is jammed in its up orientation. The system of the invention is designed for ease of use with trucks. Trucks need to be able to move smoothly on and over the ramp assembly.
It is recommended that safety measures be considered at each installation of the invention. To this end, it is considered expedient to have barriers installed on both sides of the system to prevent people or animals form falling into gaps and free spaces of the system. Again, it should be emphasized that with the invention, a vehicle (e.g., truck) driver may not ever feel as though his vehicle is going over a bump. When the vehicle goes over the ramp assembly, because of the fact that the incline ramp rotates downwardly to a flat position, the driver will feel as though he is driving on smooth road. A ramp grade of seven degrees or a even a few degrees higher or lower will provide a comfortable ride. Although the design of the system prevents the ramp assembly from jamming or getting stuck in its up position, warning signals may be employed to prevent vehicles from falling off the ramp, in case the ramp assembly becomes stuck in its up position.
It should be noted that component-intercoupling arrangements and reciprocating motion assemblies other than those described above may be used to translate the ramp assembly's up-down motion into rotation, such as that shown in
As will be appreciated from the foregoing description, pursuant to the invention, the inertial energy of a moving vehicle and the gravitational weight of a downwardly moving vehicle may be readily converted into mechanical rotation which can turn an electric generator. The primary functions of the system are those of the ramp assembly where a moving vehicle causes a linear or semi-linear motion. The linear motion is translated by a roller assembly mechanism into a full rotation or a partial rotation of a wheel. The rotation of the wheel is transferred to rotate an electric generator by means of chains, belts and gears, and the like.
To this end,

We therefore do not wish to be limited to the details shown and described herein, but intend to cover all such changes and modifications as are obvious to one of ordinary skill in the art.
