Indian students design an air-powered motorcycle

A group of Indian engineering students has invented a unique pollution free bike which runs on air pressure and does not emit carbon into the atmosphere.It takes air as fuel and emit air as exhaust.

Equipped with two compressed air cylinders, the 100cc bike currently runs at a speed of 18km per hour, but the students hope to make it faster. It's range probably is limited as well though. [via techamok].
