Patent ID: 8841788

Claim:
A Wave Energy Converter (WEC) based on a mass-spring-damper system with different degrees of freedom (DOF), wherein said WEC comprises an inertial oscillating mass-spring-damper system lodged in a housing, said inertial system comprising: a) at least one oscillating mass ( 12 ), b) springs ( 14 ), at the ratio of at least two springs ( 14 ) for each oscillating mass ( 12 ), said springs being arranged radially relative to said oscillating mass ( 12 ), and c) at least two power take-off (PTO) devices ( 13 ) at the ratio of one power take-off energy device ( 13 ) for each spring ( 14 ), one of the ends of said PTO ( 13 ) devices i) being connected radially via universal joints ( 9 ) from one end to at least one of said oscillating mass(es) while the other end of said PTO device is connected, also via universal joints ( 9 ) to the wall of said housing ( 10 ), and ii) channeling said energy to an energy storage conventional system ( 15 ), so that the motion of external disturbances including waves and wind upon hitting the system containing said WEC ( 70 ) produces oscillations in three translational degrees of freedom and three rotational degrees of freedom which are channeled to said mass-spring-damper, the energy stored in said energy storage ( 15 ) being available for utilization.
