Electricity from Beer

The brewing process produces millions of gallons of waste water. Australian scientists have developed a microbial fuel cell that contains sugar-consuming bacteria that “clean” the water and produce energy in the process. A pilot power plant is being built at Fosters Brisbane brewery. Using only a small portion of Fosters waste water, the plant hopes to be able to produce enough power to power a small home. If successful, these power generating plants could be built at other wineries and breweries. The best part is, that the process of microbes eating the starch, sugar and alcohol uses far less electricity than traditional water treatment methods. That alone would be great benefit, but these plants would instead generate electrity, and the water coming out at the end of the process would be good enough to drink.

Is there nothing that beer can't do?
