A floating wind turbine that its makers claim could significantly boost the renewable energy sector was officially launched at a trade show in the German capital. Wind turbines at sea are nothing new, but until now they have had to be sited in shallow waters so the bases could be fixed to the seabed. This not only means complicated and costly construction but also visual pollution, as the rotating blades can be seen from the shore. Unlike normal offshore wind turbines it does not need to be anchored to the seabed and can be used in waters deeper than 50 meters (164 feet), depths at which installation costs for fixed turbines become exorbitant. It will soon go into operation off the coast of Puglia in southern Italy.
