  • Patent number: 7932620
    Abstract: A windmill apparatus includes tower, a tower-mounted hydraulic pump driven by windmill blades, and hydraulic lines connected to a ground storage tank and to a number of separate generator units. Each generator unit includes a hydraulic pump and an electrical generator. In operation, upon startup, as the wind propels the propeller-driven pump the hydraulic fluid circulates freely until a pre-set pressure is achieved, upon which a diverter valve diverts all the fluid pressure to the first generator unit. When the first generator unit is powered sufficiently to achieve a stable output voltage, a subsequent one of the remaining generator units is powered up until its output voltage is stabilized, with this process continuing as long as there is a surplus of hydraulic power available to power up additional units to take full advantage of all of the available wind power.

  • Publication number: 20090273191
    Abstract: A power producing device apparatus includes a combustion engine and an electric motor connected to a dual drive transmission, and a housing. The dual drive transmission has opposing shafts, with the electric motor and the combustion engine acting on the dual drive transmission so as to drive the transmission. The entire assembly is enclosed by an enclosure which is a waterproof and sound reducing structure that can be custom designed to fit an environment it is to be used in. Examples of such an enclosure can include a log cabin for use at mountain resorts or municipalities, mini casino design, fiberglass or metal container for placement on the roof tops of high rise office and apartment complexes.
