Over at the BBC there's a great video story on a car that runs on air.

The car, well, a small van actually, has a tiny engine that runs on compressed air and uses other fuels for longer journeys. That means that during the urban cycle the vehicle makes absolutely no emissions at all. Except, for now, a bit of noise.

Inventor Guy Negre, an ex Formula 1 engineer, said that:

"The first buyers will be people who care about the environment"

Which is highly likely as the vehicle is reported to be capable of up to 140 MPG.

Monsieur Negre has been promising to deliver this concept for about 10 years now, but with the backing of Tata, the Indian manufacturing giant, the concept is close to completion.

Tata's backing helped MDI Enterprise S.A. to put the finishing touches to their Compressed Air Technology (CAT) engines.
