<p>A wave energy extraction device comprises a hull and at least one driving mass, supported on the hull by a horizontal pivot, such that the driving mass has no significant tendency to harmonic motion, and at least one energy conversion device, operatively associated with the hull and the driving mass. The vertical velocity of a wave produces a vertical velocity of the hull, this vertical velocity passing to the driving mass via the energy conversion device, the energy conversion means further extracting energy from periodic differences in the velocity of the hull and the velocity of the driving mass, at different phases of the wave cycle.</p> |
