Abstract
A wind driven power generator has a rotational shroud assembly for maximizing wind input and a turbine assembly with a shaft that rotates within the shroud assembly. The shaft end extends through the base of the shroud assembly. The turbine assembly has elongate arms attached to the top portion of the shaft of the turbine assembly. Each arm is essentially perpendicular to the shaft and has a vertical wind blade attached to each of the arm ends and spaced equidistance apart around the shaft of the turbine assembly. The shroud assembly covers approximately half of the turbine assembly during rotation and maintains a windward direction for maximum wind on the blade fronts while shielding the back sides of the blades from the incoming wind.
