Compressed air cars are powered, in short, by air. Air is compressed and then it is released which is the source of propulsion. These air cars have been in the developmental stages for many years and are very, very close to reaching wide commercial markets.
How do air cars work?
Compressed air cars use an electric pump to compress air into a tank at high pressures, effectively storing energy like a battery. That air is allowed to escape and, in a way similar to a combustion engine, it presses on the vehicle’s pistons , producing work.
The electric pumps of the compressed air car can typically be recharged using a standard electrical outlet. Keep in mind, the use of this pump and outlet do not make them hybrid vehicles, just like conventional gasoline vehicle is not hybrid simply because it requires a battery.
