Whatever your view on carbon emissions from cars, you have to admit that it would be nice if they didn't cause so much pollution. As much as I love Phoenix, without wind or rain in the summer the air gets kind of gross from several millions cars driving around.

There are lots of plans to do away with gasoline and diesel by replacing it with electricity, hydrogen fuel cells, biofuels, air power and even aluminum. But so far nothing can beat the convenience, cost or infrastructure of gas.

Carmaker Audi is taking a different approach and making its own fuel. Dubbed "e-diesel," Audi's fuel is made from water and carbon dioxide. It can be mixed with existing diesel to make it cleaner, or it could eventually be used on its own.

Because of the way e-diesel is made it doesn't release sulfur, aromatic hydrocarbons and several other pollutants. But it runs just as well as diesel and can be used in diesel-powered cars and trucks.
