Urine utilisation by Microbial Fuel Cells; energy fuel for the future

Another approach to green energy, or yellow in this case. Essentially the authors created a microbial fuel cell that uses molecules in urine (uric acid, creatinine, small peptides, etc.) to generate electricity. Imagine the grad student who had to come in to work and urinate in his fuel cell every morning for two years...

Nutty, but interesting science.
