Abstract
Several embodiments that enhance and improve the efficiencies of vertical axis wind turbine generators by expanding their normal range of useful operations. Stationary vanes provided external to the rotor blades provide directional control of wind/air flow into the blades for decreased drag and increased differential wind pressure. Control scenarios for adjusting stationary wind vanes and additional ducting of air to increase efficiencies.
