Air cars

An Air Car is a car that can run on compressed air, with out use of conventional fuels.
The car is powered by an air engine.
The air engine is an emission free piston engine using compressed air.
These engines are similar to steam engines as they use the expansion of externally supplied pressurized gas to perform work against a piston.
