Abstract: This relates to an electric power generating system particularly adapted for use in locals where there is an absence of a water supply with sufficient elevation to supply the required power for an electrical energy generating system, or the water supply is insufficient for the required generating system. The deficiency is overcome in part by providing an elevated water supply reservoir and a system of gravity actuated water powered pumps for utilizing the discharge of the generating system to pump at least a portion of the discharge to the elevated reservoir. It is further proposed to utilize a pumping system of the wave motor type for pumping relatively available water at sea level to the elevated water reservoir. It is also proposed to provide a split stream of water from an elevated water supply to two generators at different elevations with the discharge from the uppermost generator being recombined with the other portion of the split stream for introduction into the generator at the lower level.
