Patent ID: 8039985

Claim:
A wind turbine comprising: a housing having a chamber defined in the housing and having a top opening and a bottom opening; multiple cross-flow fan assemblies mounted on the housing, communicating with the chamber and each cross-flow fan assembly having a casing being hollow, mounted on the housing and communicating with the chamber and having at least one inlet hole defined through the casing; and at least one outlet hole defined through the casing and communicating with the chamber; a cross-flow fan blade mounted rotatably in the casing and selectively providing airflow to the chamber; and a transmission shaft mounted on and protruding axially from the cross-flow fan blade and having a top end and a bottom end; a turbine generator assembly mounted in the chamber of the housing and having a generator mounted securely in the chamber of the housing and having a generator shaft mounted rotatably through the generator and having a top end and a bottom end; and a turbine blade mounted securely around the generator shaft in the chamber and selectively driven and rotated by the airflow from the chamber to drive the generator; an air guide mounted securely on top ends of the transmission shafts and selectively guiding the airflow from the chamber of the housing to transversely flow outwards; and multiple wind-driven fans securely mounted respectively around and corresponding to the transmission shafts, located adjacent to the top opening of the chamber of the housing under the air guide and driven by the airflow guided by the air guide.
