Ethanol fuel, that is. A company has produced a backyard ethanol distiller. From Scientific American:

Ethanol fuel is made from a combination of water, yeast and sugar, Tom Quinn, E-Fuel founder and CEO, said at the press conference, adding that the process was no more complicated than what is taught in "third-grade science." The adoption of ethanol has been held back because drivers do not have access to the fuel, he said, pointing out that there are only 1,200 ethanol stations in the U.S., compared with about 176,000 gas stations.

To make ethanol in the EFuel100, feedstock (consisting of sugar and yeast) or discarded liquor [my emphasis] is loaded into the device's 200-gallon (757-liter) tank. Using the LCD screen located on the front of the device (next to the pump), the operator places the EFuel100 either in ferment (for feedstock) or distillation (for liquor) mode to begin the process. The EFuel100 is hooked up to a water source—much like one's washing machine or dishwasher is—and regulates the amount of water flowing into its tank to begin the ethanol-conversion process.

Uh... "discarded liquor." Come again? :-)
