Abstract
A vertical axis wind turbine is disclosed which includes an upstanding tower. A plurality of radially spaced-apart airfoil supports are rotatably mounted on the tower which extend outwardly therefrom. A generally vertically disposed airfoil blade is pivotally secured, about a vertical axis, to the outer end of each of the airfoil supports. A wind vane is secured to each of the airfoil blades which causes pivotal movement of the associated airfoil blade relative to the associated airfoil support in response to wind direction. A mechanism interconnects each of the airfoil blades to the associated wind vane which causes pivotal displacement of the airfoil blade with respect to the associated wind vane and wind flow with the pivotal displacement being of a magnitude and direction to cause a forward thrust to the airfoil blade from wind acting on the airfoil blade.
