Drink beer, fuel your car?

Brewing waste could power fuel cells?

Soon, brewing waste from Foster's Brewing Company in Australia will be creating clean energy, and while it probably won't ever be used in cars, it could be used to create electricity and clean water.

"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.
