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.

The reference frame may correspond to a video frame taken when no fire is present or a video frame immediately preceding each of the subset of the plurality of frames. At least some of the subset of the plurality of frames may be provided by a camera having a sensitivity of between 400 nm and 1000 nm that may generates 640x480 pixels per frame. At least some of the subset of the plurality of frames may be provided by a CCD camera or a CMOS camera.
