New Scientist : The energy of ocean waves is beginning to be tapped as a source of sustainable energy. Wave power , distinct from the daily flux of tidal power and the steady gyre of ocean currents , is generated by wind passing over the sea surface. As more than 100 companies develop wave energy converters to harvest energy from the ocean, New Scientist takes a look at six of the most promising technologies currently being deployed: a power buoy , an attenuator , an oscillating wave surge converter , a rotational wave energy device , an oscillating wave column , and an overtopping-wave-energy device .
