Abstract: An ocean powered Rankine cycle turbine includes a loop in which is circulated a working fluid. A first heat exchanger effects a phase change of the working fluid from liquid to gas. The gas expands to power a turbine. Gas exiting the turbine is condensed by a second heat exchanger to effect a phase change from gas back to liquid. A piston assembly is used to compress air. A wave energy converter uses ocean wave energy to reciprocally move the piston. As the wave goes down, the piston is extends drawing air into the piston housing. As the wave goes up, the piston compresses the air. Heat generated as the piston compresses air, is used to as a heat source for the first heat exchanger. Cold compressed air is used as a cold source for the second heat exchanger.

Abstract: The present invention relates to a way of pressurizing a fluid to power a load, by initially pressurizing the fluid in a series of stages to yield a low-pressure fluid and further pressurizing the low-pressure fluid concurrently in parallel stages to yield a high-pressure fluid for supply to the load.
