A cam phaser is described for selectively engaging in a torque transmitting mode or an angle control mode. In the torque transmitting mode, torque from a camshaft is transmitted to an e-motor, which functions as a generator and provides electrical energy.

An electromagnetic generator comprises one or more flux assembly having at least one coil and at least one magnetic field source separated by a gap. An interference drum has a sidewall at least partially positioned inside the gap and comprising at least one magnetic field permeable zone and at least one magnetic field impermeable zone. The interference drum is movable relative to the at least one coil and to the at least one magnetic field source to alternatively position the at least one magnetic field permeable zone and the at least one magnetic field impermeable zone of the sidewall inside the gap. When the interference drum is moved, magnetic flux is created in the coil, and induces electrical current to flow into the coil. The coil may be connected to an external circuit, such that the electrical current may flow through the external circuit.

A torque amplification device for amplifying torque of a power transmission shaft and transmitting the amplified torque to a driven shaft according to an embodiment includes one or more eccentric amplification parts including a first rotation part, to the center portion of which a shaft in the power transmission shaft direction is connected and which is eccentrically connected to a shaft facing the driven shaft in a driven shaft direction; and an output end amplification part which is connected to the eccentric amplification part through a rotary shaft in the power transmission shaft direction, includes a second rotation part connected to the outside of the rotary shaft, and transmits the torque of the rotary shaft, transmitted from the eccentric amplification part, to one side of the second rotation part so as to drive same, thereby transmitting the torque of the second rotation part in the driven shaft direction.

An energy facility that generates energy using ballistic optimized hydro-electricity. The facility sends a plurality of specialized balls from a lower storage reservoir to an upper storage reservoir. The balls fall through a drop-down system and into a power generation system with a generator and a turbine. Ballistic impacts of the balls on the turbine generate electricity before the balls are returned to the lower storage reservoir.

An electrical generator is provided. The electrical generator can include a generator, an electric motor, and a battery. The generator has a rotatable shaft and stationary component and be operatively coupled via a drive belt to the motor, which provides torque to the rotatable shaft of the generator The battery is operatively coupled to the motor. The generator can be operatively coupled to a utility grid via a transformer/invertor that can import current from the utility grid to charge the battery when the utility grid is operating and export current from the generator to a grid connector when the utility grid is not operating.

A generator unit to be attached to a traveling vehicle that has a prime mover and a PTO shaft to transmit power from the prime mover, includes: a generator; an input shaft having: a first connector portion configured to be connected to the PTO shaft; and a second connector portion configured to be connected to a working device to be connected to the traveling vehicle; a transmitter mechanism to transmit, to the generator, power supplied from the PTO shaft, the power being inputted from the first connector portion to the input shaft; and an attachment frame having: an attachment portion to which the generator, the input shaft, and the transmitter mechanism are attached; and a mounting portion configured to be mounted to the traveling vehicle.

Provided is a toroidal continuously variable transmission that can create a jet of oil resistant to the influence of wind generated by rotation of a power roller, thereby feeding a sufficient amount of oil to the power roller to cool the power roller with the oil; and a drive mechanism-integrated electricity generation apparatus for an aircraft, the electricity generation apparatus including the toroidal continuously variable transmission. The toroidal continuously variable transmission includes a discharge structure including an outlet that discharges an oil. The discharge structure includes first and second oil passages connected with each other inside the discharge structure, and arranged such that the oil flowing through the first oil passage and the second oil passage collide with each other in the vicinity of the outlet and that a jet of oil discharged from the outlet forms a flattened shape extending along a rotational direction of the power roller.

A regenerative energy system comprises a power source driving a motor that rotates a drive gear about an axis, the drive gear rotating a driven gear about an axis. The drive and driven gears each comprise radially extending teeth projecting from respective gear peripheries, the teeth meshing when the drive gear drives the 5 driven gear. Permanent magnets are disposed in at least some of the drive and driven gear teeth such that the magnetic poles of the drive gear teeth repel the poles of the driven gear teeth. When magnetic repulsive forces between the drive and driven gear teeth are overcome, the drive gear and driven gear teeth can engage one another. A coil is located in proximity to the permanent magnets. The 0 coil can form part of a solenoid. Electrical current is generated in the coil by a movement of the permanent magnets relative to the coil.
