Engineers at Moteur Developpment International (MDI, Luxembourg City, Luxembourg) have designed a prototype car that is powered by compressed air. The vehicle has a tubular chassis that is glued together, a fiberglass body, and uses wireless communication between its components. The engine weighs less than half that of a standard car. Ninety cubic meters of air is stored in carbon fiber tanks at high pressure. The expansion of the air stored in the tanks pushes against pistons to create movement.
The car is built to integrate with external electronic systems such as voice recognition, Internet connectivity, telephone connectivity, or a GPS. A hybrid model is also under development -- gasoline would be used to run a generator to supply compressed air. It is estimated that one tank of fuel would be enough for a cross-country trip.
