It's really satisfying to see new green technology go from the concept phase to reality, and today we have something to get excited about. Ocean Power Delivery, a Scotland-based company, has just announced that they will be installing the world's first commercial wave farm off the coast of Portugal. This plan has been floating (sorry) around for a while now, but it's happening now. October 2 was supposed to be the launch date, but due to bad weather, it will have to be briefly postponed.
The machines are essentially a series of semi-submerged tubes which are linked to each other by hinged joints. It is these joints which are the trick behind the system. The joints act as a pumping system, by pushing high pressure oil through a series of hydraulic motors, which in turn drive the electrical generators to produce electricity. Needless to say the machines are moored to the ocean bed. To give you an idea of the size of each module, the 750kw prototype, is 120m long and 3.5m in diameter. Each of these modules is composed of three individual 250kw tube.
