Foster's again shows that beer is good for the world

The brewmasters down under have hooked up with scientists from the University of Queensland in Australia to produce electricity. They have created a fuel cell powered by waste water from the brewing process that contains sugar starch and alcohol. Bacteria in the cell consume those and other organic substances and produce chemical energy which is transformed by the cell into electricity. A prototype unit has been operating in the University lab for three months and a larger 660-gallon version will be installed at the Foster's brewery in Brisbane. This first fuel cell will generate 2kW of power and also clean the water at the same time which is actually the primary benefit of this process.
