The hydroelectric power generating system includes a reservoir for retaining a body of water and an outer vessel that surrounds a peripheral wall of the reservoir. A circumferential canal extends between an upper portion of the reservoir peripheral wall and the outer vessel. One or more penstocks extend below the canal between the reservoir and the outer vessel. Each penstock has one or more hydroelectric turbine generators installed therealong. A plurality of primary wind turbines can be disposed on a peripheral wall of the reservoir and a plurality of air columns can be disposed within the reservoir to generate auxiliary power.

A system in a water body uses buoyant force of gaseous Hydrogen and Oxygen to generate electrical power with one or more turbines that includes power resulting from the buoyant force while transporting the Hydrogen or Oxygen to a higher elevation, without loss of electrons, for conversion to electricity at the higher elevation. Conversion of Hydrogen and Oxygen to water through a Hydrogen Fuel Cell or by burning at the higher elevation may generate additional steam power, hydropower, or purified water. Portable submersible modules may transport the system below or above the water to and from the base of a plumbing portion of the system. The amount of gaseous fuel energy available at the higher elevation is not detrimentally impacted by the generation of electricity by the turbine.

This is a machine that contains a fluid loop that is utilized by using buoyancy and gravity to produce a fluid flow through a hydro turbine or other flow energy converter within the enclosed system. In one embodiment compressed gas is injected into a vessel at the underside of a piston to create a buoyant condition which forces the piston upward, thusly forcing the fluid above the piston through the hydro turbine. In another embodiment fluid or other matter fills a hollow piston at the top of the vessel and through the force of gravity descends, thusly forcing the fluid beneath the hollow piston downward and in turn upward through the adjoined vessel and then through the hydro turbine. In both referenced embodiments alternating ascent and descent cycles can be utilized within each adjoined vessel to cause fluid flow through the hydro turbine. Other embodiments are presented within as examples.

An air-driven generator for generating electric power from movement of a working fluid. Upper ends of buoyancy conduits are in fluidic communication with an upper end of a gravitational distribution conduit, and a lower end of the gravitational distribution conduit is in fluidic communication with lower ends of the buoyancy conduits. An air injection system injects air into the buoyancy conduits. A closed fluid loop is formed with working fluid flowing from the gravitational distribution conduit driving a fluid turbine system that is interposed between the lower ends of the gravitational distribution conduit and the buoyancy conduits. Flow of working fluid can be induced by an injection of air into working fluid disposed in the buoyancy conduits to achieve a generation of power by actuation of the fluid turbine system. An upper chamber can remove entrained air. A Rankin Cycle Generator can receive and be actuated by exhausted air.
