Fuel Cells From Nanomaterials Made From Human Urine 83
New submitter turning in circles (2882659) writes 'Carbon based fuel cells require carbon doped with other elements, normally platinum, for oxygen reduction reactions. Urine contains carbon with an exciting splash of nitrogen, sulfur, potassium, silicon, and so on, and you don't have to manufacture it: the stuff just comes out by itself. In an article published this week in an open journal, researchers from Korea reported a new nanomaterial for fuel cells, which they dub "Urine Carbon." Upon drying, and then heating at 1000C, and rinsing of salts, the resulting Urine Carbon porous nanostructures outperformed Carbon/platinum in electrodes.'

Here's my question: how hot can a methane-fuelled fire get? I just had the rather humorous (and possibly disturbing) thought of batteries made of piss heated using farts as fuel. Every man could become part of his own power source.. plus we could harvest all that methane from cow farts that is supposedly contributing to global warming.
