FloWind: The World’s Most Successful VAWT

Though no longer extant, FloWind at one time was the world’s most successful manufacturer and developer of Vertical Axis Wind Turbines. FloWind manufactured two models of Darrieus wind turbines during the early 1980s and developed two prototype turbines during the mid to late 1980s. FloWind’s Darrieus turbines generated nearly 1 TWh (972 million kWh) during nearly two decades of operation. No VAWT has ever come close to that performance since and it’s unlikely that any ever will.
