The MDI Air Car - the world's cleanest car.: "After twelve years of reserch and development, Guy Negre has developed an engine that could become one of the biggest technological advances of this century. Its application to CAT vehicles gives them significant economical and environmental advantages. With the incorporation of bi-energy (compressed air fuel) the CAT Vehicles have increased their driving range to close to 2000 km with zero pollution in cities and considerably reduced pollution outside urban areas."

Any chance they'll actually take off?

I watched the video clip from the BBC but it was disappointing, they seem to have just taken a tiny clip from a full review. And I'm guessing they chose the positive bit...!

Still though, wouldn't it be great?

According to Wired the project is floundering a bit due to lack of investment... the prototypes in existence need work before they deliver on MDI's full promises, but investment is needed to do the work but investors want to see it working before investing and so on and so on...

God I hope somebody gives them money.
