The disclosure is directed to an apparatus or a system for generating energy in response to a vehicle wheel rotation. The apparatus or the system may include a roller configured to be positioned in substantial physical contact within a groove of a wheel of the vehicle. The roller may be configured to rotate in response to a rotation of the wheel. The apparatus or the system may further include a flexible arm rotatably couplable to the roller such that rotation of the roller causes the flexible arm to rotate. The flexible arm may be configured to exert a downward force on the roller to increase the friction between the roller and the groove of the wheel. The apparatus or the system may further include a first generator operably coupled to the flexible arm and configured to generate an electrical output based on the rotation of the flexible arm shaft and convey the electrical output to an energy storage device or vehicle motor.

A one-way power conversion device (24) and a power system having the one-way power conversion device are provided. The one-way power conversion device (24) includes a one-way gearbox (18), a first transmission shaft (15), a second transmission shaft (16), and a swing rotation component (19). The device includes a combination of one or more one-way power conversion devices (24), which can absorb swinging powers coming from different directions and convert the swinging powers into an available one-way rotation power. The device can absorb the swinging power in any direction, and has the advantages of a high absorption and conversion efficiency, a stable power output, low costs of construction and maintenance, a high stability, and a wide application range.

A system and method for generating, leveraging, and storing electrical energy are disclosed. The system comprises one or more walking beams having a track and at least two protective end stops located on opposite ends of the track. A plurality of counterweights is attached to the walking beams, adjacent the axle, via one or more connecting rods. An electric vehicle (EV) chassis is positioned on top of the track and allows back-and-forth movement. The back-and-forth movement makes the walking beam move up and down, which then converts into rotational movement of a flywheel via a rack and pinion arrangement, capturing an alternately falling force of counterweights, thereby rotating the flywheel for generating constant electrical output. Further, an apparatus is adapted for generating artificial fluid lift by utilizing back and-forth movement of the EV chassis.

A roadways power and energy mechanical road captures and harnesses energies imparted to the roadway by the tires of vehicles driven on the roadway. Pistons, crank shafts, and additional mechanical interconnections mounted in a housing installed beneath the surface of the roadway are connected to generators adjacent to the roadway to convert linear mechanical motion to rotational mechanical motion to generate electrical power.

A regenerative shock absorber that include a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.

A continuous push electricity generation device integrated with a loaded rotating member, comprising three or more transmission modules, each of which comprises a receiving member which is pushed in conjunction with the loaded rotating member's portion being in contact with a surface against which the loaded rotating member rolls, while being in a closed relationship with a delivering member, which is connected to a generator rotor shaft. When the receiving member and delivering member correspondingly move, the rotor shaft rotates in an opposite direction to the loaded rotating member's rotation. The device also comprises one electricity generation module, comprising a power generation rotor being in connection with the rotor shaft, and a stator. The stator is fixedly connected to the loaded rotating member's shaft and to the rotating member. The rotor shaft's rotation in an opposite direction to the loaded rotating member's rotation results with a relative rotation of the power generation rotor with respect to the stator, thereby generating electricity.

A vehicle incorporates a gravity-assist energy harvesting suspension system including one or more gravitational positive displacement pumps. The positive displacement pump has a cylinder and a reciprocating piston inside the cylinder. The piston is adapted for movement along a compression stroke and an opposite extension stroke in response to a gravitational bounce of the vehicle when in motion. A turbine comprising a rotor shaft and attached blades is mounted relative to a distal end of a fluid outlet hose connected to the pump. Fluid discharged through the outlet hose acts on the blades, thereby moving and imparting rotational energy to the rotor shaft. A generator is operatively connected to the turbine, and is adapted for converting the rotational energy generated by the rotor shaft to electrical energy.

An energy harvesting apparatus may include a housing having fluid disposed therein and a piston assembly configured to move within the housing in one of an extension stroke and a compression stroke. The piston assembly may include a bidirectional rotor configured to rotate responsive to the piston assembly moving in either of the extension stroke and the compression stroke.
