Patent ID: 8806865

Claim:
A system for extracting long wavelength ocean wave energy and for extracting rotational wave energy; comprising, a plurality of boom elements extending in a longitudinal axis; at least one hinge element; said plurality of boom elements connected to said at least one hinge element for movement about said hinge element in a direction of the vertical force of a wave or for movement about said hinge element in a direction of the transverse force of a wave; and wherein, said hinge element includes a shaft transverse said boom elements longitudinal axis; and at least one blade mounted to said shaft for rotational movement of said shaft in the direction of the rotational force of a wave; including a cable connected to said hinge element to at least two points on said hinge; a first hydraulic transducer including a first hydraulic cylinder, a first hydraulic piston and a first hydraulic piston rod; a second hydraulic transducer including a second hydraulic cylinder, a second hydraulic piston and a second hydraulic piston rod; said cable is connected to said first and said second hydraulic piston rods; and wherein said rotational movement about said hinge element in a direction of the vertical force of a wave or in the direction of the transverse force of the wave is adapted to rotate said cable about said hinge element and to alternatively pull said first and second hydraulic piston rod and said first and second hydraulic piston in a reciprocal motion.
