Abstract
Curved airfoils are mounted on members attached to a vertical shaft. The ends of the airfoils point outward from the shaft. The members are attached to the upper and lower sections of the airfoils and converge as they approach the shaft. This minimizes the shaft length above the turbines upper most bearing and provides a balanced condition that distributes forces in such a manner which reduces airfoil stress.
