OYSTER project (UK) [11]: The OYSTER WEC has been designed to capture energy found in near shore waves (Fig. 8). It is a buoyant, hinged flap which is attached to the seabed at around 10-m depth, around half a kilometer from shore. This hinged flap, which is almost entirely underwater, sways backwards and forwards in the near shore waves. The movement of the flap drives two hydraulic pistons which push high pressure water onshore to drive a conventional hydroelectric turbine.
