Abstract:
1. A machine to convert gravity to mechanical energy as the machine cycles between an un-expanded position and an expand position, the machine comprising: a) a first tank ( b) a second tank with pressurized gas and a second piston-like tank full of liquid in the second tank in the un-expanded position, the pressurized gas in the second tank being lowered as the second piston-like tank full of liquid is moved out of the second tank to the expanded position; c) a hole in a piston shaft of the first piston-like tank that allows the gas to travel between the first and second tank; d) a nose-cone full of liquid connected to the second piston-like tank full of liquid; e) a retractable stop on the first tank, f) a piston lock for each of the first and second expanded piston-like tanks full of liquid; g) a piston lock for each of the first and second un-expanded piston-like tanks full of liquid; and wherein the machine is submersed in a body of liquid and free falls in the un-expanded position; wherein the retractable stop suspends the free fall of the machine to move the machine into the expanded position; wherein the machine floats up after being expanded to do work; and wherein the retractable stop suspends the floating up of the machine to move the machine into the un-expanded position.
