The Vertical Axis Wind Turbine is a wind power generation design that puts the main rotor shaft transverse to the wind. The main components of the system are located at the base of the tower on which the vertical blades sit. This differs from the more common Horizontal Axis Wind Turbine (HAWT), where the blades attached at the horizontal rotor shaft.
