Abstract: Device for storing energy, using a physical object, such as a mass or buoyant object floating in fluid. A mass is repositioned to greater altitude in a gravitational field to a position of higher potential energy. A buoyant object is forcibly submerged into a fluid, displacing fluid, to a position of higher potential energy. The stored potential energy may be recovered with extremely low loss regardless of the state of charge of the system, or length of time of the storage. Maintaining the charge is indefinitely lossless.

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.

Abstract: Device for storing energy using a physical object, such as a mass of greater than 10,000 kg, or buoyant object, floating in fluid, capable of displacing 10,000 kg. A mass is repositioned to greater altitude in a gravitational field to a position of higher potential energy. A buoyant object is forcibly submerged into a fluid, displacing greater than 10,000 kg of fluid, to a position of higher potential energy. The stored potential energy may be recovered with extremely low loss regardless of the state of charge of the system, or length of time of the storage.

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 via the fluid, 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.
