Abstract
An improved wind turbine 10 is described having a swivel head 18 mounted at an upper end of a support tower 12 for pivoting about a substantially vertical axis Y. A radial blade rotor assembly 48 is mounted to the swivel head 18 for pivotal movement about a substantially horizontal pivot axis X that is offset and spaced downwind of the vertical axis Y. The rotor assembly 48 has a rotor shaft 50 that rotates about a rotor axis Z that is spaced from the horizontal pivot axis X. The rotor assembly has a plurality of airfoil blades 64 that are attached to and extend radially outward from the rotor axis. The blades 64 rotate with a shallow inward conical path about the rotor axis Z in the blades 64 extending radially outward at an inclined angle from perpendicular of between 0 and 5 degrees. An electrical alternator 80 is connected to the rotor shaft 50 for generating electrical power directly from the rotor assembly 48.
