Patent ID: 8134252

Claim:
A system for converting wind energy to electrical energy for a building, comprising: a conduit positioned within the building, the conduit having first and second end portions open to outer wall surfaces of the building; a wind collector positioned within the conduit, the wind collector being configured to rotate as air flowing through the conduit impacts the wind collector; a wind deflector mechanism positioned at the first and second end portions of the conduit, the wind deflector mechanism having an inward position to accelerate wind towards the wind collector and an outward position to allow wind to exit the conduit; a plurality of venturi elements pivotally mounted within the conduit, the plurality of venturi elements having first and second positions to accelerate wind towards the wind collector and being configured to allow for bi-directional airflow within the conduit such that the first position accelerates wind towards the first end portion of the conduit and the second position accelerates wind towards the second end portion of the conduit; and a wind turbine device operatively connected to the wind collector to generate electrical energy for the building from the rotation of the wind collector.
