Abstract

The invention is a wave energy device which optimizes energy conversion from waves with a stable submerged platform coupled to compliant chain of floats ("pods") which are connected to the platform by piston pumps. Wave action drives pumps to deliver pressurized water to a hydro turbine coupled to an electric generator for delivery of electric power to shore via a submarine cable. Alternatively, the pressurized water may be delivered to shore through pipes on the ocean floor, to generate electric power, also as input flow for reverse osmosis potable water production and for cooling applications.
