US lab develops gigantic turbine blades to capture vast wind energy
US researchers at Sandia National Laboratories say they are working on a design for gigantic wind turbine blades that are longer than two football fields which could support 50-megawatt-- more than six times the power output of the largest current turbines --offshore wind farms in the future.+More on network World: Energy Dept. wants big wind energy technology in all 50 states+Sandia researchers said most US wind turbines produce power in the 1- to 2-MW range, with blades about 165 feet (50 meters) long, while the largest commercially available turbine is rated at 8 MW with blades 262 feet (80 meters) long. A 50-MW turbine requires a rotor blade more than 650 feet (200 meters) long, two and a half times longer than any existing wind blade, the researchers stated.To read this article in full or to leave a comment, please click here
