  • Hybrid wave energy plant for electricity generation
    Patent number: 8511078
    Abstract: The innovation herein proposed describes a plant to produce electricity by the sea waves. The plant is designed to be installed on shore, near shore and offshore scenarios: on the coast line, in shallow waters and in deep waters. The plant is operated by action of the sea waves on a series of floaters (A). The resultant force on each floater (A) acts on a mechanical load amplifier (B) which moves two vertical high pressure piston pumps (C). These pumps (C) send pressurized fresh water to a hyperbaric system (E). The hyperbaric system (E) supplies an outflow water jet through a controlled valve that moves a conventional turbine (G). This turbine (G) connected to the electric generator (H) produce electricity.

  • Wave energy plant for electricity generation
    Patent number: 8099955
    Abstract: The invention herein proposed describes a plant operated by the movement of floaters (A) connected to horizontal arms (B). These arms (B) move hydraulic pumps (C), which inject water into the hyperbaric chamber (E). This chamber (E) supplies water through an outflow control valve, to set in motion a conventional turbine (G) that connected to electric generator supplies electricity.
