![]() ![]() “If you have all those advantages, why would anyone build a conventional wind turbine?”īut to become a widespread source of electricity, airborne wind energy, as it’s also called, needs to overcome a number of technological and commercial hurdles, as Bauer and colleagues describe in an upcoming paper in the 2022 Annual Review of Control, Robotics and Autonomous Systems. The carbon footprint is also much smaller, he says. ![]() “It’s cheaper to manufacture, cheaper to transport and also has higher efficiency,” says Florian Bauer, co-CEO and chief technology officer of Kitekraft, a Munich-based company developing a kite power system. Kites might also be a better choice for offshore wind power, and one day could even replace at least some anchored towers now in use. If they succeed, kites could make it possible to build wind farms on land that isn’t windy enough for conventional wind turbine towers. Flying massive kites 200 meters or more above the ground, companies are using the wind they find there to generate electricity.Īt least 10 firms in Europe and the United States are developing variations of this kind of kite power. Any kid who’s ever flown a kite has learned the lesson: Once you can get the kite off the ground and high into the air, you’re more likely to find a steady breeze to keep it aloft.Ī fledgling wind power industry is taking that lesson to heart. ![]()
