An energy company says its ducted wind turbine produces six times more energy than traditional, vertical turbines seen around the world. It recently announced the ability to install multiple turbines in a single unit, a first for the industry
I tried to come up with something to bring wind to the turbine and generator instead of taking the generator to the wind,” says Daryoush Allaei, founder, SheerWind Chaska, Minn. and creator of the wind turbine system he calls INVELOX. He adds that the US Department of Energy (USDOE) asked him, in 2009, to look into a wind turbine design that had no noise, radar or optical-flickering issues. “We started asking basic questions like, ‘why are turbines 20 meters in the sky and why are they so big?’” says Allaei.
