ABSTRACT:
A vehicle compressed air energy converter has been developed for use along vehicular roadways, railways and airfield runways to collect wind pressure developed by the vehicles, trains and aircraft moving through the atmosphere and convert such air motion to other useful forms of energy. The converter is activated by the force of the compressed air movement entering the converter and pushing the retractable air fins of the converter in a circular motion. That circular motion is transferred to a central shaft set in bearings at either end of a housing. As the multiplicity of air fins held in place by hinges on a circular rotating base move within the converter housing, the fins move into a retracted posture so as to offer less air resistance as they circulate within the portion of the converter not subject to movement of air from the exterior of the housing. As the fins rotate to the position wherein exterior compressed air enters the converter the fins then extend to a position to maximize the resistance to the incoming wind pressure. The air pressure causes rotation of the fins and central shaft of the converter thereby transmitting torque energy to the belt pulleys on the shaft. The wheels attached to the outer edge of each air fin travels on elliptical shaped band tracks thereby causing the fins to retract and extend as rotation occurs.
