US Patent 9163606 Hydro-electric tube generation

Disclosed is a hydro-electric energy system comprised of an inner and outer tube designed to contain and distribute water such that failing water powers hydro-electric turbines located in the inner tube. The system may be located in a body of water taking in and distributing the surrounding water, or on and utilizes natural or/constructed/water sources. A number of different pump types are utilized at the bottom of the inner tube to maintain water levels and water flow within the system. In certain embodiments the pumps are driven by pressure and gravitational forces. In other embodiments supplemental power sources drive the pumps either power generated from the system's turbines or power sources external to the system.
