ABSTRACT:
Power is generated by subjecting a body of water in an evacuated chamber alternately to pressure corresponding to the vapor pressure of water at the surface of a body of water, such as tropical sea water, and pressure corresponding to the vapor pressure of subsurface water. The body of water falls and rises in correspondence with the changing pressures and the pressures are alternated in synchronism with the natural period of oscillation of the body of water so as to increase the amplitude of its oscillation. Power is withdrawn from the oscillating body of water either by feeding overflow water to water turbines or by anemometer type turbines within the chamber. Apparatus details are disclosed.
