So there's obvious appeal to the idea that you could turn cheap liquor into cheap gas in the time it takes you to down an ice-cold martini (made with the good stuff). Say hello to your new personal gas pump, the EFuel100MicroFueler.
Rather than waiting in line on a smoggy street corner for the privilege of being gouged mercilessly, roll right up to the EFuel100 residing in your driveway (or garage, or basically anywhere with a power outlet and a water hookup) to fill any gas-burning auto with your homemade batch of ethanol. Just pour in the mix of sugar feedstock and yeast—or the residual gin from your Bootlegger's Ball '05 gathering—and after a few days, fill 'er up. The MicroFueler makes 35 gallons a week, each gallon costs you about $1, and your car will actually enjoy a little more power (which is why IndyCar racers use ethanol).
Sure, you can brag about the purported environmental benefits of your newfound gasoline independence, but there's also a certain satisfaction in using that gas money you saved somewhere else.
Like the bar.
