University of Kansas scientists report a slowdown effect triggered by wind turbines is substantial for large wind farms and results in proportionally less renewable energy generated for each turbine versus the energy that would be generated from an isolated wind turbine. Renewable wind energy is experiencing a boom, with more wind turbines popping up across […]

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 […]

Vortex, founded in Spain by three men whose co-founder scientist David Yáñez, has developed a wind power generator without a turbine with wing blades. The Vortex generator uses vorticity, a word formed from the activity potential of a vortex. A vortex can be seen where water twists around going down a drain, in the air […]

A University of Texas at Arlington (UTA) research associate and electrical engineering professor have designed a micro-wind turbine that generates electrical energy.  Their target looks to be an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large wind turbines are not possible. Smitha Rao and J.-C. Chiao […]
