2100 tons of steel were put in the ocean 3 miles off Portugal yesterday. Don’t worry this is a good thing. Three steel snakes, each over 450ft long, will slither on the surface. The articulation of the four sections of each snake by the waves will be converted into power, enough currently for 1,000 homes. Plans are to add 25 more to the area to generate up to 21MW of power. The idea and construction comes from Pelamis, a British-owned company.
