India invents car that runs on air

Why didnt we think of this first?

Actually, the idea has been kicking around since the late 19th century. Compressed air engines have been used in a variety of applications, for example, in early torpedoes. My prediction would be that this car will go the same way as every other compressed air propulsion system - nowhere. There are way too many efficiency problems to overcame.
 
they(tata) are talking about it for years..

Tata Motors

As of January 2009[update] Tata Motors of India had planned to launch a car with an MDI compressed air engine in 2011.[22] In December 2009 Tata's vice president of engineering systems confirmed that the limited range and low engine temperatures were causing problems.[23] Meanwhile any related articles or connections to MDI have been deleted from the website of Tata Motors, including in the archive

Compressed air hybrids are already in the works. In lieu of harnessing the braking energy to generate electricity for recharging, the energy is used to compress nitrogen and store it in a tank under high pressure. It is a more efficient system than the electric hybrid as the air system can recapture and store a greater percentage of the braking energy.
 
$2 for 100Km and the top of speed of 105kph. This can be real game changer and more so because the emission is clean. Awesome! :D :p :)
