Drink more Foster's, mate

From an AP story featured on the livescience site:

Scientists and Australian beer maker Foster's are teaming up to generate clean energy from brewery waste water – by using sugar-consuming bacteria.

The experimental technology was unveiled May 2 by scientists at Australia's University of Queensland, which was given a $115,000 state government grant to install a microbial fuel cell at a Foster's brewery near Brisbane.

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...."Brewery waste water is a particularly good source because it is very biodegradable ... and is highly concentrated, which does help in improving the performance of the cell," Keller said.
