The first cars on compressed air used in the 19th century, mostly in mines.

Compressed air also powered trams and locomotives. Various pneumatic tools are also started today with compressed air.

Compressed air accumulates energy produced at one time, and it is used at another time. Compression can be done by means of an electrically powered turbocharger and expansion by means of a turboexpander, or by a compressed air motor running the power generator.

Compressed air systems are a very inexpensive and long-lasting way of accumulating energy. By economics, they can be measured with reversible hydropower. They are long-lasting and after use there is no harmful waste.

The biggest problem with compressed air vehicles is the energy density.

One liter of oil has usable energy as 6 liters of compressed air. That's why the ordinary car should have a tank of 300 to 400 liters. Such a reservoir would take up the whole luggage space, which is impractical. Some car manufacturers such as Tata in India have tried to solve this problem but failed.

However, this problem is very easy to solve.

As a compressed air storage facility, it is possible to use a supporting structure of the vehicle. A sturdy construction of the vehicle can be made from a tube of 25 to 30 centimeters in diameter. Such a construction could store 300 to 400 liters of compressed air. Such compressed air is less hazardous to storing natural gas, or hydrogen.

Car charging could be done at night when electricity is cheaper. This could also be done at home using an electrically powered turbocharger. Compression releases a lot of heat energy. That heat energy could be used to heat the house in winter.

In driving electric energy would be generated by turboexpanders, or by a compressed air motor that drives the power generator. Electricity would drive electromotors at each point of the vehicle. And all other vehicle systems would be powered by electricity.

The air coming out of the system has a temperature of about -15 degrees, and it could be used in the summer to cool the car's space.
