Guy Negre

There's no shortage of alternative fuels contending to augment or displace gasoline in cars: ethanol, biodiesel, hydrogen, and so on. To that mix you can now add compressed air. European automaker Motor Development International is working on a line of cars that won't drive all that fast, but that are expected to be easy on the atmosphere.

The gent in this picture is Guy Negre, founder and president of MDI, and that car is the MiniCat. (The "Cat" part is short for, you got it, "compressed air technology.") The company's headquarters are in Luxembourg, and the factory where the cars are produced is in Carros, France. But there's a New Delhi angle as well.
