Foster's beer cell battery

Australia's University of Queensland, along with Foster's beer's Yatala brewery, have joined to test out a microbial fuel cell to generate electicity.

"The fuel cell is essentially a battery in which bacteria consume water-soluble brewing waste such as sugar, starch and alcohol.

The battery produces electricity plus clean water, said Prof. Jurg Keller, the university's wastewater expert.

The complex technology harnesses the chemical energy that the bacteria releases from the organic material, converting it into electrical energy.

"It's not going to make an enormous amount of power - its primarily a waste water treatment that has the added benefit of creating electricity," Keller said. "

The predict the 660 gallon fuel cell will produce 2 kilowatts of power. Definitely a guilt lowering idea, but I wonder how much it actually costs in terms of resources?
