Are Backyard Ethanol Brewers an Answer to High-Priced Gas?

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.
Interested drivers in the U.S. can put in their orders now for their own EFuel100 MicroFueler at the company’s Web site with a $3,000 down payment toward the total $10,000 tab; the first units are expected to ship some time this fall. The company, which has plants in Los Gatos and Paso Robles, Calif., as well as Hong Kong, also plans to sell MicroFuelers in Brazil, China and the U.K.

The prototype rolled out at a press conference in New York City yesterday is 72 inches (1.8 meters) high, 42 inches (1.1 meters) wide and 72 inches long, but the company says the consumer units are likely to be a bit smaller.
