IPC: F03B13/24
Filed: 2006-06-21
Abstract: The apparatus for converting sea wave energy into mechanical energy is a device that uses sea wave energy to rotate a wind turbine. The system consists of an arrangement of interconnected underwater air chambers and, through the action of the sea waves and the assistance of a pair of throttle valves, via each air chamber, the air contained in the inside thereof is circulated in one direction through a central turbine. Its simple design, with no moving parts in contact with the water, and the fact that it is underwater reduce its impact on marine life and shipping routes. Its modular nature makes it easier to handle in general during manufacture and installation, which makes it attractive in terms of cost. Applications include: generation of electricity, generation of hydrogen and oxygen and desalination of sea water.
