ABSTRACT:
The invention provides a device for extracting energy from waves on a liquid upon which the device is adapted to float. The device is allowed to move in response to the waves, and has a shape below the surface of the liquid, position of center of gravity, and value of radius of gyration about the center of gravity, in a vertical plane aligned in the direction of propagation of the waves, adapted so that the device in response to the waves inhibits to a substantial extent the transmission and/or reflection of waves by the device itself.
