An electricity generator powered by air flowing from an air conditioner exhaust having a grill housing attached, the grill housing made of wind turbines connected to movable magnets freely movable clockwise or counter-clockwise to function whether the air flows in a first direction or opposite the first direction, thereby arranged to generate electromotive electricity as the turbines move, the turbines being oriented transverse to the air flow and a plurality of screws attaching the grill containing the wind turbines in a fixed transverse orientation relative to the air flow direction of the air conditioner exhaust wherein the wind turbine has a cage-like propeller with at least one flattened blade having a 180 degree twist located about mid-point and connected to a shaft, the shaft being connected to a generator and driving the generator creating electricity by moving conductors in a magnetic field. The grill holds the wind turbine so the blades are turned by exhaust air from the air conditioner and electricity is generated by moving conductors through alternating north and south magnetic fields.

1. An air flow energy recovery system for recovering energy from air flowing out of a unit having at least one exhaust face with at least one exhaust location wherein a fan fixed in proximity to the unit circulates air from the unit comprising: (a) an electrically powered air blower having a propeller mounted on a motor, whereby the air blower produces an air flow, the air flow being blown in a selected direction;(b) a grill attachable to one exhaust location, the air flow having at least one outlet location constrained by the grill, the grill containing at least one oblong squirrel cage having rotable blades, a shaft supported at each end by bearings, wherein the air flow from within the housing is expelledout of the housing as directed air flow directed through the grill covering at least one exhaust location; andat least one squirrel cage circulatable independent to any other when air flow is directed in the vicinity of the squirrel cage fan structures, the squirrel cage fan structures each being exterior to the housing and inside the grill, each squirrel cage fan structure being spaced a selected distance from the housing to allow the squirrel cage fan to rotate freely, each such squirrel cage fan structure having: a rotatable shaft; a plurality of vanes attached to said rotatable shaft, wherein the air flow acts on at least one of said vanes, rotating said rotatable shaft; and an electrical generator connected to said rotatable shaft. 2. The energy recovery system of claim 1 wherein electrical energy from said electrical generator is directed to a converter and converted to alternating current. 3. The energy recovery system of claim 1 wherein the electrical energy from said electrical generator is directed onto an electrical grid connected to the air conditioner. 4. The energy recovery system of claim 1 further comprising a feed from the electrical generator to an electrical system for providing a supply of electrical power to the unit. 5. The energy recovery system of claim 4 further comprising a device for connecting the electrical generator to a power system and means for selectably connecting the electrical generator to either the unit or the public power system. 6. The energy recovery system of claim 5 wherein each blade of each squirrel cage fan is a flattened elongated rectangular piece of durable material, each blade being formed into a semi-circle with an apex and having a first end and a second end, the first end being connected at a first location on the shaft, the second end being connected at a second location on the shaft, each blade being gradually twisted to one hundred and eighty degrees at its apex whereby capture of air currents by each blade is improved. 7. The energy recovery system of claim 6 wherein each said shaft has a middle section contiguous to the first location and contiguous to the second location and located in between the first location and the second location, the first end of the shaft extending through a bearing having a round opening for receiving the first end of the shaft, the second end of the shaft extending through another bearing having another round opening for receiving the second end of the shaft, the shaft having a variable diameter, the variable diameter of the shaft being largest at the middle of the shaft and substantially tapered at each end sufficient for the shaft to maintain its position wherein the first and second ends remain retained in their respective bearing openings. 8. The energy recovery system of claim 1 further comprising a feed for connecting the electrical generator to a public power system.
