Queen of England Buying the World's Largest Wind TurbineWe don't know how much it cost her, but word is that the Queen of England has put down some mega-bucks to buy the world's largest wind turbine. The 10-megawatt monster machine built by Clipper Windpower of Carpinteria, California will have a wingspan larger than two soccer fields and will stand 574 feet tall when completed. The windmill is expected to displace two million barrels of oil as well as 724,000 tons of CO2 over its lifetime. It will also serve as the flagship for Clipper's Britannia Project, an effort to produce massive new turbines on deep-sea floating platforms. If all goes as planned, the Queen's windmill will light up thousands of British homes starting in 2012. [CNN]
