Science in the Toilet

I across these two items which are just a little too odd for comment.

Scientists harness the power of pee
"Physicists in Singapore have created the first paper battery that generates electricity from urine. The new battery will be the perfect power source for cheap, disposable healthcare test-kits for diseases such as diabetes. The research is published today in the Institute of Physics' Journal of Micromechanics and Microengineering. "

Cows show promise as powerplants
"A new study at Ohio State University suggests that some of the microorganisms found in cow waste may provide a reliable source of electricity. Results showed that the microbes in about a half a liter of rumen fluid - fermented, liquefied feed extracted from the rumen, the largest chamber of a cow's stomach - produced about 600 millivolts of electricity. That's about half the voltage needed to run one rechargeable AA-sized battery,"

OK one quick comment. Can you imagine having too piss on your tester to check your diabetes, or picking up a fresh cow's stomach to recharge your walkman?
