Wind Power’s Next Hope: Blades as Long as Two Football Fields

Inspired by the way palm trees move in high winds, a group of researchers at the University of Virginia and Sandia National Laboratory are developing an extremely long wind turbine blade that could make it possible to construct 50-megawatt turbines–far beyond the power of today’s, which tend to produce just two megawatts. The blades, designed under a program funded by the U.S. Department of Energy’s ARPA-E program, would be 200 meters long, 2.5 times the length of the longest blades commercially available today.
