All these BBC pages are about one thing: the potential uses of urine.
“A research team at Heriot-Watt University is investigating whether urine could be used as a source of renewable energy. The scientists have developed a system to test whether it can be used in fuel cells as an alternative to flammable hydrogen or toxic methanol.”
“A growing number of scientists have cottoned on to the fact that urine is a source of vital enzymes for medicine, precious minerals like fast-depleting phosphorus, and chemical compounds like urea, which are crucial to the manufacture of fertilisers, plastics and cosmetics and can also be used to make electricity.”
“One product that we can be sure of an unending supply is our own urine,” [Dr Ioannis Ieropoulos] said. “By harnessing this power as urine passes through a cascade of microbial fuel cells (MFCs), we have managed to charge a Samsung mobile phone.”
