Vertical-axis wind turbine
Videos
A vertical-axis wind turbine is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allow

The Darrieus wind turbine is a type of vertical-axis wind turbine used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft

…need to be pointed into the wind, which removes the need for wind-sensing and orientation mechanisms. Major drawbacks for the early designs (Savonius, Darrieus and giromill) included the significant torque ripple during each revolution and the large bending moments on the blades. Later designs addressed the…
