Wave Power in Portugal

Wave Power in Portugal
The world's first commercial wave farm has gone live off the coast of Portugal, Agucadoura near Porto.
Giant sea snakes tethered some three miles from the coast will generate electricity. They are made up of a series of tubes, each about the size of a train, linked together, and pointed in the direction of the waves. The waves travel down the tubes, causing them to bob up and down, and a hydraulic system harnesses this movement to generate electricity.
The aim is to construct several hundred machines generating 500MW of electricity, enough to light up 350,000 homes. The scheme has been developed by the Edinburgh-based company Pelamis.
