Patent ID: 7003955

Claim:
An enhanced pumped storage power system comprising: an upper reservoir in the form of a man-made lake for containment of water, a lower reservoir at a location lower than the upper reservoir, wherein said upper reservoir is at an elevation of about 20 feet to about 50 feet above said lower reservoir, at least one reversible turbine and generator unit, a first conduit extending from the upper reservoir to said at least one reversible turbine and generator unit, located in proximal relation to said lower reservoir, wherein downward flow of the water through said first conduit serves to engage and rotate said at least one turbine and generator unit for the purpose of generating electrical power, and wherein, during periods of low energy demand, said at least one turbine and generator unit is reversed so that it functions as a pump powered by conventional means, thereby directly pumping water upwardly through a second conduit to return the water to said upper reservoir.
