Method and device for harvesting energy from ocean waves

Номер: US20120001427A1
Принадлежит: Individual

A method and device for generating electricity from ocean waves. The device includes at least one magnetostrictive element and one or more electrically conductive coils or circuits. When the magnetostrictive element is deployed in a body of water, the motion of the body of water, including wave motion, causes changes in the strain of the magnetostrictive element. The electrically conductive coil or circuit is within the vicinity of the magnetostrictive element. A corresponding change in magnetic field around the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit.

This invention discloses the efficient, non-polluting generation of electricity through the construction and use of an electric power generating system wherein electricity is generated by utilizing the powerful subsurface undercurrents present near an ocean shoreline. The undercurrent water is caused to cycle internally through a conical shell housing assembly constructed in an upwardly narrowing configuration to produce a nozzle effect within the shell housing. The nozzle effect generates a combined water and air power piston that alternates in a vertical direction within the shell assembly. In both the upward and downward cycles, the power piston impacts a fan blade component that causes the shaft of an electricity generating turbine to rotate and produce electricity.
