Abstract: A method of increasing oxygen levels in aquaculture involves pumping water from a body of water into a temporary holding tank and storing air under pressure in a storage vessel. The method involves enriching a stream of pressurized air from the air storage vessel by the introduction of oxygen from a downstream source of oxygen and directing the oxygen enriched stream of pressurized air into water drawn from the temporary water holding tank. The method then involves passing the oxygen enriched stream of pressurized air and water through at least one mixer, whereby a mixing of the oxygen enriched stream of air into the water occurs to create oxygenated water. The oxygenated water in then introduced into water used for aquaculture at an aquaculture facility.

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.
