Compressed-air vehicle is the solution to urban pollution and urban mobility. It is a real breath of fresh air in cities and the prelude to travel without pollution. A compressed-air vehicle is an electric vehicle using compressed air as storage.
A compressed-air vehicle is powered by an air engines, using compressed
air, which is stored in a tank. Instead of mixing fuel with air and burning in
the engine it to drive pistons with hot expanding gases, compressed-air vehicle
(CAV) use the expansion of compressed air to drive their pistons. The use of
that air in the engine is 90% efficient.
Compressed air propulsion may also be incorporated in hybrid system,
e.g. battery electric propulsion and fuel tanks to recharge the batteries. This
kind of system is called a hybrid-pneumatic electric propulsion. Additionally,
regenerative braking can also be used in conjunction to this system.
How
the Air vehicle Works
The laws of physics dictate that uncontained gases will fill any given
space. The easiest way to see this in action is to inflate a balloon. The
elastic skin of balloon holds the air tightly inside, but the moment you see a
pin to create a hole in the balloon’s surface, the air expands outward with so
much energy that the balloon explodes.
Compressing a gas into a small space is a way to store energy. When the
gas expands again, that energy is released to do work. That’s the basic
principle behind what makes an air car go.
