Wave energy generator pumps power to Scotland
Published: 25 Nov 2009 09:57 GMT
Wave energy received a boost with the connection of the Oyster hydro-electric device to the electricity grid in Scotland last Friday.
Aquamarine Power activated the connection of the Oyster in the waters off Orkney, marking one of the few ocean power devices to be producing electricity.
The device is a hydraulic pump operated by a 'hinged flap', where a large metal piece moves back and forth from the motion of the waves. The movement moves a hydraulic piston that pumps water underground to a hydro-electric turbine that drives a generator to make electricity.
