BUOYANT ACTUATOR FOR WAVE POWER GENERATOR WITH VARIABLE RESPONSE AREA

摘要

576872 A buoyant actuator (10) for a wave energy conversion system is disclosed. The buoyant actuator (10) comprises a body (21) defining a chamber (23) for accommodating matter. A hydrodynamic property of the body is selectively variable during operation of the buoyant actuator by changing the volume or shape of the body (21) to vary the response area.
