The Pelamis absorbs the energy of ocean waves and converts it into electricity. The machine floats semi-submerged on the surface of the water and is made up of a number of cylindrical sections joined together by hinged joints. As waves pass down the length of the machine these sections flex relative to one another. The motion at each hinged joint is resisted by hydraulic cylinders which pump fluid into high pressure accumulators allowing electrical generation to be smooth and continuous. Control of the resistance applied by the hydraulic cylinders allows generation to be maximised when waves are small, and the machine response to be minimised in storms. All generation systems are sealed and dry inside the machines and power is transmitted to shore using standard subsea cables and equipment.Locations:Europe-Orkney Islands-Scotland-United KingdomDate:29 Sep, 2011Credit:© Steve Morgan / GreenpeaceMaximum size:4213px X 2809pxKeywords:Climate (campaign title)-Day-KWCI (GPI)-Oceans (topography)-OutdoorsShoot:Wave and Tidal Power on Orkney IslandsTidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity.As tides are more predictable than wind energy and solar power, tidal power has potential for future electricity generation. Scotrenewables Tidal Power Ltd is a renewable energy research and development business based in the Orkney Islands.The Scotrenewables Tidal Turbine is a unique floating tidal technology designed to minimise installation and operational costs. The system has been extensively trialled through scale model testing and a 250kW prototype -the SR250- is currently generating power in a two-year test programme in Orkney.
