Surfers and bodyboarders know just how powerful a big wave can be, and scientists are onto the scent as well. So far, the Pelamis Wave Converter is the most developed technology for converting waves into electricity. The 600 foot long red machine is made up of cylindrical sections linked together floating on the ocean's surface. Waves make the sections flex and bend, generating power.
In May of 2010, Pelamis launched the device off the shores of Scotland, and is hoping to have hundreds more in seas around the world in the next decade. More recently, an even more impressive technology has been proposed: British designer Phil Pauley is working on marine solar cells, connected by a web, that would collect both solar and wave power.
