Abstract
A wind power extraction device has a rotor with a hub and a rim coupled to the hub through a plurality of blades. The blades rotate the rotor about an axis of rotation passing through the hub in response to a wind moving generally parallel to the axis of rotation. A mount coupled to the rotor extends and retracts the rotor between a first configuration aligning the rotor axis of rotation substantially horizontally, and a second configuration aligning the rotor axis of rotation substantially vertically. The device may have components of an electric generator mounted in or near the rim.
