"IT MAY seem ridiculous, but in the hunt for sources of alternative energy researchers have come up with fuel cells which are powered by cheese—or at least whey, a by-product in cheese making. Whey is rich in lactose, a sugar which Georgia Antonopoulou, a biochemical engineer at the University of Patras, Greece, says can be consumed by cultures of bacteria contained within a fuel cell to generate an electric current. Microbial fuel cells, as such devices are known, are not a new idea but they are attracting more attention."
Interesting idea.....the stuff is so nutritious it's sad to me that it's considered "waste."
What if all the whey from cheese factories was carted over to the chicken farms? Anyway. Here's another idea for what to do with it all.
