| Are Backyard Ethanol Brewers an Answer to High-Priced Gas?
Quote
A company banking on drivers' weariness of skyrocketing gasoline prices unveiled a home refinery device on Thursday offering another option: ethanol. E-Fuel Corporation says its EFuel100 MicroFueler can produce up to 35 gallons (132 liters) of ethanol a week that consumers can pump directly into their cars and trucks. There is no combustion inside the device, which runs on a standard household 110- to 220-volt AC power supply (consuming about 150 watts per day) and uses a membrane system to distill the sugar, yeast and water solution required to make ethanol rather than combustion heating elements, as commercial ethanol producers do. |
