A recirculating linear generator comprises a motor, a pulley system, two series of coil structures each arranged coaxially, a positive lead, and a negative lead. The pulley system includes a driver pulley driven by the motor and a take-up pulley. A belt couples to the driver pulley and the take-up pulley, so when driven, the belt travels along the driver pulley and the take-up pulley rotates. A series of ferromagnetic couple to the belt. The belt and masses traverse through a center (i.e., an axis) of the first series and second series of coil structures, and the first series and second series of coil structures each comprise a single electrical path. The positive lead couples to positive ends of the first and second series of coil structures, and the negative lead couples to negative ends of the first and second series of coil structures.

A magnets-based generator is disclosed that comprises a stagnant-magnet anchored to a chassis; a wandering-magnet that is designated to be propelled from a first position to a second position and vice versa; an E-magnet and a J-magnet disposed adjacent to one end of the wandering-magnet; and at least one pair of buffers disposed between the stagnant-magnet and another end of the wandering-magnet. The wandering-magnet moves from the first position to the second position by joining the E-magnet and the J-magnet together and splitting the pair of buffers apart, and it moves from the second position to the first position by splitting the E-magnet and the J-magnet apart and joining the pair of buffers together. The generator further comprises an energy converter adapted to generate electrical energy from movements of the wandering-magnet from the first position to the second position and vice versa.

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.

The present invention pertains to systems and methods for controlling machines that generate electricity using a source of renewable energy, namely gravity. In overview, an electro-magnetic subsystem of the machine harvests the kinetic energy of a buoyant shuttle as it falls through air and into a bi-level tank. The shuttle is then arrested in the bi-level water tank and returned, by virtue of the shuttle's buoyancy, to its start point for a subsequent duty cycle. The return of the shuttle is made possible by a hydro-pneumatic subsystem of the machine that overcomes the potential energy needed to raise and lower the upper water level in the bi-level tank to compensate for a transit of the shuttle through the tank. The hydro-pneumatic subsystem does this by cyclically maintaining the required difference in water levels in the bi-level tank.

A system for generating electricity includes a bar and a source of a pressurized fluid. A three-way connection piece has an inlet opening connected to the source through an inlet solenoid valve and a discharge opening connected to a discharge solenoid valve. A connection line connects the three-way connection piece to a working cylinder. A shaft of the working cylinder strikes against the bar causing an oscillating motion. A first and a second rod convert the oscillating motion into a back-and-forth translational motion which a drive means converts into a cyclical drive motion. An apparatus for generating electrical energy is driven by the cyclical drive motion. During operation, the inlet solenoid valve and the discharge solenoid valve are continuously switched from a first working position to a second working position, and vice versa, at a frequency which is identical to the natural frequency of the bar.
