Could a car run on compressed air?
Yes, it could. You could compress the air at your house using an air compressor, fill a compressed-air tank in the car, and the car could run off of it. You could use an engine very similar to a steam engine (using pressurized air instead of pressurized steam) to convert the compressed air to rotational energy.

An alternative would be to use a liquefied gas like liquid nitrogen. You can think of liquid nitrogen as air that has been compressed so much it has liquefied. Liquid nitrogen is much denser than compressed air, so you could store enough in a car to give it reasonable range. You could then fill up at the liquid-nitrogen station. A compressed air car would generate no
