DEEP SEA FLOATING WIND FARMS


As Shell Oil gets closer to risking the Arctic habitat to drill [for a projected measly supply of 4 years domestic energy], here's better news in energy development:

From The Guardian: 
Six miles off south-west Norway, the first full-scale demonstration of a floating wind turbine heaves and sways in the North Sea. The depth of water, at 200 metres, rules out driving piles into the seabed, or mounting the turbine on a submersible tower. Instead, it sits on a buoyant steel cylinder, kept upright with ballast, and tethered (not too tightly) to the seabed by a three-point mooring. With floating platforms, wind could be tapped over the deeper seas of the Mediterranean, and off Japan and off both coasts of the US, says Peter Jamieson, of energy consultants GL Garrad Hassan, the author of Innovation in Wind Turbine Design.
