Students of an engineering college in Rajkot, Gujarat, have developed a prototype car that runs on air instead of petrol or diesel.

The four students started their endeavour about a year ago as a final-year project. Instead of the usual fuel tank, the prototype is fitted with an air tank. The students have used parts of old cars to make the vehicle at minimal cost.
The students were constantly assisted by the teaching staff as well as the principal in developing the design.
