Carbon nanotube-reinforced polyurethane could make for bigger and better wind turbines

Carbon nanotube-reinforced polyurethane could make for bigger and better wind turbines:

"In the effort to capture more energy from the wind, the blades of wind turbines have become bigger and bigger to the point where the diameter of the rotors can be over 100 m (328 ft). Although larger blades cover a larger area, they are also heavier, which means more wind is needed to turn the rotor. The ideal combination would be blades that are not only bigger, but also lighter and more durable. A researcher at Case Western Reserve University has built a prototype blade from materials that could provide just such a winning combination."
