Abstract
A vertical axis wind turbine having a platform and a roof forming a housing for a vertical axis rotor and a stator. Stator vanes extend between the platform and the roof. The stator vanes and guiding surfaces on the platform and the roof define inlets and airflow paths for guiding wind into the inner chamber of the housing, where the wind powers a vertical axis rotor that is rotatably supported on the platform. The stator vanes are segmented with the trailing edges dynamically adjusting the diameter of the inner chamber in response to changing wind and rotor speed conditions. A shaft extending from the rotor can be connected to a generator connected to a power grid. The roof can support a solar panel connected to the power grid.
