Abstract
A system for converting the kinetic energy of the ocean into electrical energy. There is presented a water-filled pipe extending from the shore into the ocean. The sunken end opens into a water-filled piston sleeve standing upright on the ocean floor. The sleeve contains a buoyant piston extending either to the ocean surface or into an internal wave field. Since the end of the pipe located ashore ends into either a Bourdon Tube or Cartesian Diver then passing waves or tide action will vary the pressure of the water in the Bourdon Tube or Cartesian Diver. Machinery is presented that can convert the elastic potential energy of a Bourdon Tube and Cartesian Diver into kinetic energy to operate an electric generator. There is no complicated and expensive electrical machinery offshore, there is no significant movement of mechanical or hydraulic parts offshore and there are no significant friction losses in bringing the energy ashore.
