Harnessing Ocean Wave Power Provides Cheap Electricity

An often overlooked renewable energy resource is the power of ocean waves.  Scientists in California say harnessing energy from the regular movement of large amounts of water could provide cheap electricity and drinking water for coastal communities. The relentless line of waves breaking along a coastline represents a steady stream of energy. The problem is that the water in waves actually goes up and down, a motion which is hard to convert into a force pushing only one way, like a...
