| 20100237631 | Oscillating Power Generator - An electrical power generating apparatus utilizes an oscillating assembly to power at least one generator. The oscillating assembly comprises an off-balanced wheel assembly having either a partially circumferential wheel ring or a circular wheel ring with an off-balanced weight distribution, assembled to a centrally located wheel hub. The pendulum assembly is pivotally assembled to a frame via the wheel hub. A counterbalancing beam extends upwardly from the wheel hub, bisecting the wheel, placing equal mass to each side, such that the pendulum assembly is symmetric. Weights can be disposed upon each of the counterbalancing beam and the wheel assembly to aid in optimizing the teetering operation of the oscillating assembly. As the oscillating assembly operates, the motion is transferred to the at least generator which creates an electrical power output. An actuator injects energy into the oscillating motion to overcome any losses due to friction, air resistance, and such. | 09-23-2010 |
