The United States of America consumes nearly 20 million barrels of oil a day, 6.6 billion per year. This depleting chemical composition, in part, ends up in our air, on our trees, on our clothing, in our lungs, in our blood streams. A large portion of this oil is imported causing a dependency on foreign countries and a significant economic burden to this country. Clean, renewable, domestic energy is a necessity, not a luxury. The Z-333 Energy Management System is an answer to this challenge. There have been many Vertical Axis Wind Turbine patents issued since Mr. Elhanan L. Stoners' patent in 1891. However it appears that none has yet manifested itself into a large scale economic reality. The Z-333 Energy Management System is the latest of a series of improved Vertical Axis Wind Turbine designs which will make that reality come to pass. The Z-333 Energy Management System includes several novel changes to previously patented designs, plus incorporates totally new accessories to make man's continuing conquest of wind an actuality. These innovations include; Aerodynamic “balanced” wings. Tightly stretched fabric-only wings strengthening the overall structure, and at the same time, drastically lower the cost of construction. Flexible photovoltaic cells cover the aforementioned fabric-only-wings. A rotating tower that is flexible and safer. A unique high winds shut off switch. A multi-generator braking system maintains the shaft at a constant RPM. Generators and gears mounted to removable panels. Rubber-like covered shaft and large ring transmission. A low cost switch that controls the angle of attack of the wing with less problems and cost. A tower made of prefabricated interchangeable modules that can be used as a home, water tank, storage room, shop, and/or a shed. A base which is also a large battery and/or a control box shell. A programmable intelligent control box, which notifies the owner by cell phone, of battery fast charge/discharge, vandalism, key energy indicators, integrates a multi-circuit station timer, plus provides an electric-fence-like shock protection from animals and vandals. Low cost, multi-pancake generator that is highly efficient. A shaft centered flywheel. A shaft centered centrifugal pump. A sea base with ballast for low cost erection. A sea base with desalinization equipment built inside. A sea base with integrated hydrogen and oxygen producing equipment.
A vertical axis wind turbine comprising a base, a vertically extending shaft rotatably mounted in said base, a plurality of vertically spaced, radially extending first arms having their inner end portions fixedly connected to said shaft at each end portion thereof, a plurality of vertically spaced, radially extending second arms pivotally connected to said first arms, a vertically extending wing fixedly connected at each axial end thereof to a respective second arm, each wing having a leading edge and a trailing edge, a fixed spindle depending from the outer end portion of each first fixed arm, each second arm being freely rotatably mounted on a respective spindle, a torsion spring having one end connected to a respective fixed arm and the opposite end connected to a respective second arm for biasing the respective wing to a first position and brake means operatively connected to the first and second arms to limit the rotation of each wing relative to the first arms.
