If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge – a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s Risoe DTU National Laboratory for Sustainable Energy tell us that such blades can flex by up to six meters (20 feet) when subjected to strong wind gusts. Worse yet, the gust load is often not evenly distributed along the length of the blade, so it doesn’t flex evenly. Fortunately, the researchers are working on addressing this problem, by attaching flexible flaps to the trailing edges of the blades. These flaps come in the form of silicone rubber strips, which run the length of the blade. The result, we’re told, will be quieter, higher-output turbines...
