Sea creatures are inspiring the latest devices that harness wave power. This one called Oyster on the sea floor and opens and closes as waves pass over it. Cables attach it to generators on the shore. Since the November 2009, it’s been powering 9000 homes in the Orkney Islands. Another device looks like a snake. The anaconda is made from a rubber tube filled with water that floats just below the surface. When the swell hits the front of it. The tube squeezed above ripples done its links and power a turbine in its tail. Prototypes are currently being tested, but the full-scale version will be 2000 meters long. This system also looks like a snake. But this one is made of steel. It floats near the surface, where waves make its joints move, this rive hydraulic system that power electrical generators, like the anaconda. It’s being tested, results will prove that these devices are up to the job of supplying variable sources of green energy. Now many devices are simulating sea creatures, the first device simulates oysters, which float in the sea by using the energy from wave. The second is the anaconda device operating like snakes, which create energy by spraying water in the tube. The third is also based on snakes, but made of steel, creating electrical energy that is a kind of green power.
