Gravity field energy storage and recovery system

Abstract

Invention defines a method and apparatus for storing energy where a power source is used to reposition a mass in a gravitational field to a position of higher potential energy where the stored potential energy may be recovered with extremely low loss, where the force of gravity may be allowed to accelerates the mass, where the resulting kinetic energy is converted to shaft horsepower. Said shaft horsepower may be converted to pneumatic, electrical, or hydraulic power. A variation defines a method where a power source is used to submerge a buoyant object in a fluid, where the submerged object represents a potential energy, where the force of gravity displaces the submerged buoyant object, where the kinetic energy resulting from the displacement is converted to shaft horsepower. Said shaft horsepower may be similarly converted to pneumatic, electrical, or hydraulic power. Invention defines a process where available energy can be used to do work to raise a massive object against a planetary gravitational field, to a position of high potential energy which can be maintained indefinitely. On demand the mass can be accelerated by the gravitational field and converted to kinetic energy, which is harnessed and converted to shaft horsepower, allowing the desired energy recovery from the energy storage system.
