Abstract

This specification describes a completely new and different concept, method, mechanization, apparatus configuration and sequencing procedure for obtaining commercially useful energy and power, namely: the use of a gyroscope to generate output power from the earth'"'"'s stored inertial rotational (flywheel) energy by fixing the housing of the gyroscope to the earth and using the rotation of the earth relative to the gyroscope'"'"'s spatially stable rotor/gimbal assembly to rotate the input shaft(s) of a power transducer(s). This provides a power-output stroke over a near 180° precession excursion (near pole-to-pole alignment) until the rotor spin axis of the gyroscope is nearly aligned with the polar axis of the earth. Re-precession torques are then created on the inner gimbal within the gyroscope to re-orient the rotor spin axis vector direction by re-precessing the rotor spin by somewhat more than 180° to the near polar alignment direction required for the resumption of power output in a manner requiring essentially zero energy and power to provide relatively continuous, but intermittent, power output generation along with a multi-unit assembly for producing continuous uninterrupted power output.

An "Advanced Concept" based on rate gyro characteristics showing promise of enhanced performance is included.
