ABSTRACT:
A windmill installation adapted to extract energy from natural wind currents is disclosed wherein a plurality of individual wind wheel modules are stacked vertically in a tower-like structure and are interconnected with one another to operate in a unitary manner. Each module has a rotor assembly which is disengageable from the rotor assemblies of other modules without interrupting the generation of power from the installation. A rotatable windshield is provided about the rotor assembly for improving output efficiency of the wind wheel and protecting the rotor assembly from damage in the event of excessively high wind speeds. The angular position of the windshield is determined by an automatic control system responsive to wind speed and direction.
