Patent ID: 8013462

Claim:
A wave energy converter comprising: a primary surface-piercing floating body; a secondary surface-piercing floating body interconnected to the primary body for longitudinal oscillation of the primary and secondary bodies relative to one another; a slug mass visco-elastically connected to the primary body, the slug mass having an effective mass characteristic, a stiffness characteristic and a damping characteristic; and a generator drivingly connected between the primary and secondary bodies, the generator having a load damping characteristic; wherein; at least one of the effective mass characteristic, the stiffness characteristic, the slug mass damping characteristic and the generator load damping characteristic is dynamically controllable; the primary body comprises a pillar; the slug mass is supported inside the pillar; and the secondary body comprises at least two rigidly interconnected floats spaced-apart from one another and spaced outwardly from the pillar.
