A bi-level tank includes a transfer tank and a return tank containing a volume of water, including transfer and return components in the transfer and return tanks, respectively, and a transition component. A bellows couples an upper surface of a piston in the transfer tank to the return component that exerts pressure on the upper surface, while a lower surface of the piston is under pressure from a pressured fluid supplied by a source thereof, producing a pressure differential on the piston. Actuation of a force-applying mechanism on the piston sufficient to overcome the pressure differential displaces the piston for exchanging respective volumes of the return component and the fluid from the source. An extensible and retractable constant-volume boot holds the transition component around the bellows and has valves configured to open and close for equalizing pressure between the boot and the transfer tank.

An gas-driven generator system for generating electric power from movement of a working liquid. The system includes a gas-driven generator that includes a liquid turbine system fluidically interposed between the lower end of an elongated gravitational distribution conduit and the lower ends of plural elongated buoyancy conduits. A heavy working liquid flows from the upper ends of the buoyancy conduits and is fed into the upper end of the elongated gravitational distribution conduit. Working liquid flows down the elongated gravitational distribution conduit to actuate the liquid turbine system. An injection of refrigerant gas into the working liquid in the plural elongated buoyancy conduits induces upward flow of the working liquid. The system includes a solar thermal heating system fluidically coupled to heat exchangers that transfer heat collected by the solar thermal heating system to the working liquid through a thermal transfer fluid circuit.

A capillary action propulsion system includes an absorbent material, at least one compression member, and a fluid. The absorbent material forms an endless path. At least one compression member compresses a portion of the absorbent material at a compression location. A fluid is disposed within the absorbent material in an unequal distribution with a first side of the absorbent material having more fluid than a second side. The absorbent material is configured to continuously rotate due to the at least one compression member compressing the portion of the absorbent material at the compression location causing the fluid to continuously remain unequally distributed within the absorbent material creating a weight imbalance in the absorbent material and a resulting moment. The fluid is configured to continuously rise, due to capillary action, within the absorbent material along the endless path from the compression location on the first side of the absorbent material.

A system and method for harvesting electric energy from the earth's gravitational field includes a pneumatic, potential energy (PE) system which cumulatively generates a volume of compressed air with an energy equal to PE, during a predetermined duty cycle. This energy can then be released as an instantaneous burst of energy in the next consecutive duty cycle. Also included is an electro-magnetic system which continuously generates kinetic energy (KE) as a shuttle falls under the influence of gravity during each duty cycle. An interface between the two systems is provided by a water column that separates the two systems yet allows them to be interactive. Specifically, the burst of PE manipulates the water column to maintain its integrity as the shuttle uses the water column as a water pathway for a return to the shuttle's start point under the influence of its buoyancy.
