    Abstract: A Horizontal Axis Airfoil Turbine (HAAT) for harnessing wind power is presented. The horizontal axis airfoil turbine has an airfoil design configured for low cut-in-speed and operational speeds, and for high torque operation. Multiple airfoil blade tips depend inwardly from a structural shroud along the periphery of the shroud. A number of full airfoil blades depend inwardly from the shroud along spokes providing mechanical engagement between the shroud and a central hub. Advantages are derived from a large wind swept area distributed to maximize leverage in order to enable high torque operation.
