A generator apparatus has a main shaft with an electric generator motor in driven connection therewith. A weight element is coupled to an end of the shaft and is supported radially outward of the longitudinal axis of the shaft. Leveraged movement of the end of the shaft in a cyclical motion imparts a tangential force on the weight element creating angular momentum which carries the weight element about a generally circular path relative to the longitudinal axis of the shaft, thereby rotating the shaft. The electric generator motor is driven by rotation of the shaft to produce electric power.
Techniques and devices that use precession of at least one spinning gyroscope to drive a motor generator to produce electricity from an oscillating motion that causes the precession of the gyroscope. A buoy may be used to produce the oscillating motion from the motion of water waves so that electricity may be produced from motion of water waves. An oscillating motion caused by other sources, such as wind, may also be used to generate electricity.
