August 19, 2009: Running on Mountain Dew

We've all done it -- the game is too good to stop, so we power up with a highly caffeinated beverage. Turns out, an inventor in New Mexico is thinking the same thing for gas-powered engines. The new fuel delivery system still requires about 25% hydrocarbons, and a gallon of "gamer's delight" runs about $4, so the invention isn't an Exxon killer quite yet.

But next summer? We might be choosing between driving the car or staying up an extra hour.
