University of Cambridge researchers have devised a new material that mimics the wing structure of owls which could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics. Because wind turbines are heavily braked […]

Researchers at Fraunhofer-Gesellschaft have built a new type of steel blade for wind turbines formed from a 1.0 mm steel sheet and featuring integrated, folded reinforcement. Today’s wind turbines use very large rotor blades made with fiber-reinforced plastics that are almost impossible to recycle. But steel blades recycling ability exceeds 90 percent. Plus they cost […]
