Abstract
A two-stage, omnidirectional vertical axis wind turbine includes a first chamber in which a plurality of angularly spaced horns guide wind from any side of the wind turbine into a chamber to rotate a first rotor. Wind exiting the first rotor passes through a diverter to produce laminar flow. A fan attached to the shaft intercepts this laminar flow to add additional torque to the shaft.
