On a somewhat lighter note, from Physorg.com, Australian beer maker Foster's is going to generate clean energy and clean water from brewery waste water by using a fuel cell in which bacteria consume the sugar, starch and alcohol in the waste.
The fuel cell is expected to produce 2 kilowatts of power — enough to power a household — and the technology would eventually be applied in other breweries and wineries owned by Foster's. The cell should be operating at the brewery by September."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," said Prof. Jurg Keller, the university's wastewater expert. .
The 660-gallon fuel cell will be 250 times bigger than a prototype that has been operating at Australia's University of Queensland laboratory for three months. The experimental technology was unveiled Wednesday by scientists at the university, which was given a $115,000 state government grant to install the microbial fuel cell at the brewery.
