The shock-absorber comprises: a cylinder containing a hydraulic working fluid; a piston slidably arranged in the cylinder so as to split the cylinder into two variable-volume working chambers, namely a first working chamber, or extension chamber, and a second working chamber, or compression chamber; an auxiliary conduit in fluid communication on one side with the first working chamber and on the other with the second working chamber; a train of permanent magnets slidably arranged in the auxiliary conduit so as to reciprocally move along the auxiliary conduit, dragged by the working fluid flowing between the first and second working chambers through the auxiliary conduit as a result of the reciprocating motion of the piston in the cylinder; and electric energy generating device for generating electric energy by exploiting the movement of the train of permanent magnets along the auxiliary conduit.

The subject matter of the invention is a vibration-to-electric energy converter by translating reciprocating motion of vibrating elements of a vehicle to circular motion of a driveshaft of an electric generator, fitted with at least one drive unit containing a toothed gearing and at least one freewheel. The converter according to the invention has a movable element that transmits vibrations to two ends of a drive chain, finished with fixing elements with nuts used for tension adjustments and with tensioning springs, whereby the chain interacts with a small cogwheel of at least one gearing, coupled via a freewheel with a large cogwheel of that gearing, connected by means of a short chain with a drive wheel of at least one electric generator, where both the axis of the gearing and the generator are fitted to a base constituting an immovable element.

A system for employing gravity to provide electrical power for mining operations in a mine includes a battery configured to power an electric vehicle. The vehicle includes a kinetic energy capture system that can charge the battery as the vehicle conveys a loaded vehicle down a ramp from an ore face to a chamber. Traveling down the ramp produces a surplus charge in the battery due to a weight differential between a loaded vehicle traveling down a ramp producing more energy via the kinetic energy capture system than energy used by the vehicle to convey the empty vehicle up the ramp to the ore face. A discharging device disposed in the chamber is configured to discharge the surplus energy out of the battery and into the mine's power grid. One or multiple trips between the ore face and the chamber may fully charge the battery.

A device that converts linear motion into electricity using the exiting movement of a system or equipment such as electric vehicles, motorcycle, or similar equipment. This device can replace the shock absorber of an existing electric vehicle generating electricity that can be used to charge the batteries extending the range of the vehicle. The device is simple an efficient and it comprises of a screw, a plurality of gears used to amplify rotation, a rotor that has magnets, and a stator that allows the coils to produce electricity.

A magnified linear power generation system. The magnified linear power generation system may be used with a vehicle and include a mechanical magnification component and a linear power generator. The linear power generator can have a mover and a stator. The mechanical magnification component can be coupled at opposite ends to the mover and to a force receiving surface of the vehicle. When the mechanical magnification component receives a force and a velocity from the force receiving surface, the mechanical magnification component may magnify the velocity and transfer the magnified velocity to the mover. The mover may move along the stator and convert the input mechanical energy into electrical energy. The mover may be coupled to a biasing component distal from the mechanical magnification component. The biasing component can apply a biasing force to the mover to position the mover at a neutral location in the linear power generator.

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.
