"Oyster" Device Harnessing Near Shore Wave Power

Ovidiu Sandru — Sat, 14 Mar 2009 19:04:23 +0000

The Oyster is basically a steel oscillating wave surge converter. It is fitted with double-direction water pistons, deployed near-shore at depths of 10 to 12m. As waves activate it, the pump delivers high pressure water through a sub-sea pipeline straight to the shore, as seen in the picture above.
