A federal permit for a test of up to 10 wave-powered generators off the Oregon coast came last month, enough, according to New Jersey-based manufacturer Ocean Power Technologies, to power about 1,000 homes. No sunshine? Wave energy could produce twice as much electricity—2 million mw—as the world currently produces.
“Wave energy is essentially an accumulation of wind energy,” Charles F. Dunleavy, the chief executive at Ocean Power Technologies, said in a telephone interview. In the northern Pacific, he said, consistent winds fuel consistent waves, and the distance they travel in their rolling line creates a huge area of wave energy, or fetch, that a bobbing buoy can capture. Other places with good fetch include some areas off the coasts of Western Europe and South America.
It would be great to power EV's like the Volt with with ocean waves as well as sunshine!
