A research effort by professor Mahesh Bandi, head of the Collective Interactions Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) has used turbulence theory combined with experimental wind plant data to explain the statistical nature of wind power fluctuations. Its an important work not to be overlooked. Professor Bandi’s work has […]

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 […]

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 […]
