Abstract
A power producing spinner () for a wind turbine (), the wind turbine () having a plurality of blades () interconnected about an axis of rotation () by a hub (). The power producing spinner () includes an aerodynamic shape () extending radially outward from the axis of rotation () to define an upwind airfoil portion () disposed upwind of an inboard portion () of each blade () of the wind turbine (). The power producing spinner () is effective to extract energy from an air flow () flowing over the spinner () and to increase an aerodynamic efficiency of the blades ().
