The Darrieus wind turbine is a type of vertical-axis wind turbine (VAWT) used to generate electricity from wind energy. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds. Gorlov proposed a similar design in 1995 • • • Darrieus's 1927 also covered practically any possible arrangement using vertical airfoils.
