Air is n not actually the source of energy, it is the storage medium. An air powered car is surprisingly cheap to run. Without the need for a cooling system, ignition and no internal combustion these engines can be produced much more cheaply than conventional car engines.
The big advantage of MDI technology is its efficiency. This is because the MDI engines have much less variation in efficiency across its operating range than internal combustion engines. ot actually the source of energy, it is the storage medium.
