An Irish university has launched the world’s largest hydro-electric wave energy converter off the coast of northern Scotland.
The so-called Oyster is a mechanically-hinged flap that is embedded into the sea floor — at a depth of about 32 feet (10 meters) — and moves with the motions of the waves. That wave energy pumps high-pressure water to a shore-based electric turbine.
Power will be fed into the national grid and provide electricity to homes in the Orkney islands. Researchers say a farm of 20 Oysters could eventually provide enough electricity to power 9,000 three-bedroom homes.
