Progress For Extreme Scale Wind Turbine Blades
February 2, 2016 | 1 Comment
Sandia National Laboratories are showing new design for 650 foot wind turbine blades in an effort to bring offshore 50-MW wind turbines to the United States and the world. Sandia National Laboratories’ research on the extreme-scale Segmented Ultralight Morphing Rotor (SUMR) is funded by the Department of Energy’s (DOE) Advanced Research Projects Agency-Energy program. The […]

Dense Wind Turbine Farms Shown to be Less Efficient
September 2, 2015 | Leave a Comment
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 […]

Owl Based Study Shows How to Make Silent Wind Turbines
June 25, 2015 | 6 Comments
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 […]

Meet The Wind Generator Without a Turbine
May 12, 2015 | 1 Comment
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 […]
