Tata Motors, the company responsible for the world’s cheapest car (and the owner of Jaguar Land Rover, as an aside), is developing a car that runs on compressed air. Imagine that. Tata owns the licence to develop a compressed air engine created by Motor Development International (MDI), a company formed in 1991 in Luxembourg.

The MDI engine has been in development for years, and had originally been scheduled for public release in a Tata air car in 2010 – Tata bought the licence for the engine five years ago.
