Patent ID: 7375436

Claim:
A method for using a gyroscope to generate electricity, comprising: engaging a crank arm to an electromagnetic motor-generator to be rotatable in full revolutions around a motor rotation axis of the electromagnetic motor-generator that is perpendicular to the crank arm; fixing a gyroscope onto the crank arm at a location away from an interception between the motor rotation axis and the crank arm so that the gyroscope moves with the crank arm and to align a spinning axis of a gyroscope wheel in the gyroscope along a radial direction of a rotation of the crank arm around the motor rotation axis; providing a base, on which the electromagnetic motor-generator is mounted at a fixed position, to interact with an external oscillating motion so as to cause the spinning gyroscope to precess and to cause rotation of the crank arm around the motor rotation axis so as to convert the external oscillating motion into a continuous rotation motion of the crank arm around the motor rotation axis; and controlling a spinning speed of the gyroscope wheel of the gyroscope in response to an oscillating frequency of the external oscillating motion to sustain the continuous rotation motion of the electromagnetic motor-generator to generate electricity.
