Abstract

A wind turbine system which includes multiple vertical or horizontal axis turbines 3 and a variable geometry nose cone 1 which opens about a pivot axis which is further away from the opening when in the expanded configuration than in the contracted configuration. Also included are side fins/flaps 7 for directing airflow through the housing for maximum venturi effect and a variable geometry rear cone 4. Each of the turbines may drive a plurality of generators which may switched in depending on the wind conditions. In another arrangement an infinitely variable drive, in the form of variable diameter cones and a belt drive is used to transmit force from the turbines to the generators. The wind turbines may be grouped together to form a wall or barrage of generators.
