Abstract

The wind turbine generator system utilizes environmental wind to produce electricity through wind-driven rotation of a turbine generator. The system includes a housing having upper and lower portions and a main open cover mounted thereon. The main open cover is configured to direct wind through an opening formed through the upper portion and into an interior thereof. A main turbine is rotatably mounted within the upper portion, with the environmental wind directed by the main open cover driving rotation thereof. The main turbine has a central aperture formed therethrough, with rotation of the main turbine driving air flow downwardly therethrough. A secondary turbine is rotatably mounted in the lower portion of the housing, with the secondary turbine being driven to rotate by the downwardly driven air generated by the main turbine. The secondary turbine partially drives rotation of the main turbine. An electrical generator is linked to the main turbine.

Dependent claims

A wind turbine generator system, comprising:

a housing having upper and lower portions, the upper portion having an opening formed therein, the upper portion defining an interior region, the lower portion having at least one vent formed therein;
a main open cover mounted on the upper portion of the housing, the main open cover being configured to direct environmental wind through the opening and into the interior region of the upper portion of the housing;
a main turbine rotatably mounted within the upper portion of the housing, the environmental wind directed by the main open cover driving rotation thereof, the main turbine having a central aperture formed therethrough, rotation of the main turbine driving air flow downwardly through the central aperture;
a secondary turbine rotatably mounted in the lower portion of the housing, the secondary turbine being driven to rotate by the downwardly driven air generated by the main turbine and by environmental wind entering through the at least one vent formed through the lower portion of the housing, the secondary turbine being mechanically linked to the main turbine to partially drive rotation thereof;
and
an electrical generator linked to the main turbine for generating electricity.
