Abstract
A device for efficiently extracting hydrodynamic energy from ocean waves, comprising a floating platform structure, an anchoring means which is connected to piston shafts of an array of hydraulic cylinders having pistons therein within the platform structure which act through a network of check valves as piston pumps for transferring hydraulic fluid from an air cushioned low pressure reservoir to an air cushioned high pressure reservoir, a hydraulic motor or turbine mechanically coupled to an electric generator and hydraulically connected between the two reservoir tanks which produces electricity as fluid is allowed to flow through the motor or turbine from the high pressure reservoir to the low pressure reservoir.
