A wind turbine includes a rotor rotatably mounted to a vertically disposed shaft. A plurality of circumferentially spaced elongated mounting arms extends radially from the rotor. A corresponding plurality of elongated generally planar sails extends along and is pivotally connected to the elongated arms. Sails are balancingly mounted on the arms and rest in a rest position generally at a 45° angle relative to a horizontal disposition when not acted upon by wind or rotor rotation. As the sails drive the rotor, the balanced sails move effortlessly into and out of alignment with the direction of current flow of the wind.
