The Circular Sea Clam Wave Energy Converter
- 370 Downloads
The SEA Clam Wave Energy Generator has been developed to a prototype design suitable for supplying electricity to island communities and coastal communities. It consists of a 120 m long floating spine supporting six air bags breathing through self-rectifying Wells turbines into a common air duct. An alternative configuration of the SEA Clam has been model tested at Loch Ness and has achieved a dramatic improvement in efficiency. This paper describes the structural configuration of the Circular SEA Clam and explains the features which led to a breakthrough in performance. Predictions are made of the cost of power produced by a 60 m diameter full scale unit deployed in the North Atlantic.
