A subterranean energy storage system configured to store and subsequently release potential energy. Storage of potential energy is achieved by the transfer of a pseudo fluid from a first storage tank to a second storage tank located above the first storage tank, and is subsequently released by the transfer of the pseudo fluid from the second storage tank to the first storage tank. To transfer the pseudo fluid between the first and second storage tanks, the subterranean energy storage system comprises at least one continuous conveyor mechanism extending through at least one transport shaft, wherein the at least one continuous conveyor mechanism comprises a plurality of vessels arranged along a length of the continuous conveyor mechanism. The subterranean energy storage system further comprises an energy transfer means operably connected to the at least one continuous conveyor mechanism to transfer power to and from the subterranean energy storage system.

An electric generating precipitation collection system comprising a collection tank, a plurality of pipes, a plurality of valves, a piston assembly, and an outlet. The system is configured to collect a liquid, direct the liquid through the pipes and valves to pressurize the liquid with the piston assembly, and eject the pressurized liquid at the outlet.

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.
