  • Generator device for use with a ventilating turbine
    Patent number: 7839010
    Abstract: A generator device is arranged for use with a roof ventilator including a base arranged to be supported in a roof opening in a roof and a ventilating turbine rotatably supported on the base so as to be arranged for ventilating a space below the roof through the roof opening when rotated. The generator device includes a generator having an input shaft and being arranged to produce electricity when the input shaft is rotated and a coupling mechanism arranged to couple the input shaft of the generator to the turbine. A roof top ventilating turbine can thus be readily converted for capturing wind energy at low cost using existing equipment.
