Australia takes beer seriously:
Australian brewer Foster's has teamed up with scientists to create the world's first "beer battery".
....The battery will be installed at Foster's brewery in Brisbane.
As bacteria consume water-soluble waste from the plant such as starch, alcohol and sugar, the battery will produce clean water and electricity.
"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 the university's waste water expert, Professor Jorg Keller.
...."It's not going to make an enormous amount of power - it's primarily a waste water treatment that has the added benefit of creating electricity," Prof Keller added.
