Wave power generator wins UK James Dyson Award

A multi-axis wave energy converter that can harvest energy no matter which way the sea is running has won the UK leg of the James Dyson Award.

The Renewable Wave Power (RWP) generator relies on loosely coupled pistons to absorb forces from the peaks and troughs of waves in any given direction. Inventor Sam Etherington, a mechanical engineering graduate from Brunel University, says it can convert external movements into hydraulic pressure much more efficiently than conventional linear devices. He will now receive £2,000 from the James Dyson Foundation to conduct more tests and enrol his device in European trials for fledgling tidal power systems. His project also goes through to the international final where a cash prize of £30,000 is up for grabs.
