A wave energy converter 100 comprises a heaving buoy 120 coupled to an adjustable reference mass 125 comprising a volume for accommodating sea water. The heaving buoy 120 and the adjustable reference mass 125 move together in response to passing waves. A chamber 105 within the heaving buoy is in fluid communication with the sea for trapping a volume of air above an enclosed column of water. The height of the enclosed column of water varies as the point absorber 122 reacts against its surface via an adjustable air-spring. A power take off turbine is driven by a stream of vented air from the chamber 105 as the point absorber reacts against the trapped volume of air. The reference mass is adjustable by opening valves 150 at either end of vertically orientated cylinders 146 to trap sea water. The resistance of the turbines may be varied e.g. using switched reluctance generators. |
