Beer as a battery?

This article was sent to me. Earlier this week the BBC announced that Foster's brewery in Australia received a grant to build a battery that would capture the energy produced by bacteria consuming sugars in brewery waste water. It is said this battery could power an entire home. They hope to use this technology in other food and drink processing plants. Along with producing power, this process will help clean the waste water. If you don't understand the power of microorganisms and consumable sugars found in beer, check my earlier post and watch the video to see how the yeast produced enough CO2 to blow off the top of my primary fermenter.
