Reliable wind turbines are important in high-wind areas or after a power failure. One such vertical-axis wind turbine (VAWT) employs the Magnus effect to operate in strong winds, using spinning cylinders and cylinder wings. With a rotation 10 times slower than a blade turbine and not as powerful, this VAWT is operable in typhoon winds and less noisy.
