University installs prototype 'Pee Power' toilet

"The technology uses microbes which feed on urine for their own growth and maintenance. The MFC is in effect a system which taps a portion of that biochemical energy used for microbial growth, and converts that directly into electricity - what we are calling urine-tricity or pee power.
