So simple, yet so efficient: Oyster® is a simple mechanical hinged flap connected to the seabed at around 10m depth. Each passing wave moves the flap, driving hydraulic pistons to deliver high pressure water via a pipeline to an onshore electrical turbine. Multiple Oyster devices are designed to be deployed in utility-scale wave farms typically of 100MW or more. http://www.aquamarinepower.com/technologies/
This is just awesome. Talk about renewable.
