Abstracts: AIR POWERED CAR is a pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries, ranging in size from hand held turbines up to several hundred horsepower, some type rely on piston and cylinders. It is hard to believe that compressed air can be used to drive vehicles. However that is true, and the “AIR CAR” as it is popularly known, has caught the attention of researchers worldwide. It has zero emissions and is ideal for city driving conditions. MDI is one company that holds the international patents for the compressed air car. Although it seems to be environmental- friendly solution, one must consider its well to wheel efficiency. The electricity requirement for the compressing air has to be considered while computing overall efficiency. Nevertheless, the compressed air vehicle will contribute to reducing urban air pollution in the long run.
