E-Fuel Corporation is developing a home ethanol system, the E-Fuel 100 MicroFueler.

It will be about as large as a stackable washer-dryer, sell for $9,995, and ship before year-end.

Using sugar as its main fuel source, it could cost as little as a dollar a gallon to make ethanol, which would produce one-eighth the carbon of the same amount of gasoline.
