Presently, the whole world exists on the use of fossil fuel for transportation purposes. A lot of research had been going on to find alternatives to this problem so as to free people from use of fossil fuels.

This dream has now come true as Guy Negre of France, the CEO of MDI Group; he has been successful in manufacturing a car that would solely be driven by air. Guy Negre is a mechanical engineer by profession who has the distinction of designing nearly one hundred engines. This mega achievement by MDI will bring about a revolution in the world auto industry!

Approximately, 10,000 air cars will be produced per year which would cost around US $ 17,800 a piece. The USA will be the first country to use this car. All these issues necessitated the manufacture of a car that should be cost-effective, efficient and environment-friendly which has now been achieved!

An air car basically runs on compressed air. We cannot use air in its existing form, available all around us. This air has to be compressed so as to store energy. This is done squeezing this air tightly in a robust container of the car with the help of a mechanical air compressor. Once the compressed air is released, it expands. This expanded air is used to drive pistons and turn the crankshaft that powers an engine which results in the movement of the car. We can say that the engine converts the compressed air stored in the tank of the car to rotational energy. The power thus produced runs the car at an approximate speed of 55 kilometers per hour. When the car exceeds that speed, a motor comes into action and the car's internal air compressor kicks in. It compresses more air and provides extra power to the engine thus making the car cruise at higher speeds.

The air car doesn't use any battery; instead, it uses compressed air to store its energy. The tank of the car can be filled with compressed air from a pump station in about three minutes' time. At home, it will take nearly three and a half hours to fill.

It doesn't involve complicated technology as it is all mechanical. Any country can venture into the manufacture of this car. But, as it has already been developed, it wouldn't be advisable for any country to re-invent the wheel. Rather, it should sign a deal with MDI to co-produce this vehicle as has been done by many countries like Germany, Israel, South Africa, etc. Research, however, could be undertaken side by side for further development and refinement of the car by involving talent from the country's local universities and the auto industry.

The cost of vehicle production will be reduced by about 20 per cent, as there would be no need to manufacture items like cooling systems, Ignition systems, silencers, etc. The mechanical design of the engine is simple and easy to maintain. The time taken to refill the tank is much less than the time required for recharging the batteries. The price of fueling these cars is much cheaper as compared to the current fuels. At service stations, a tank will be filled by paying only two dollars, approximately Rs.160.00, which would take the car for another 200-300 km.
