A group of British researchers has reached a truly piss-poor solution to phone battery life: piss! That is to say, a urine-powered fuel cell that outputs an electricity. Here it is on video:
How does it work? Bacteria placed in the fuel cell consume your pee, and naturally output electrons as a result–those electrons produce an electrical charge, you plug your phone in, and voila. Once you get over the initial eyebrow-raising, it’s kind of amazing: you’re using your own waste for power. Recycling!
Unfortunately, it doesn’t output much–about enough for one phone call–but the team hopes their invention might be implemented in bathrooms, “helping to power electric razors, toothbrushes and lights,” according to the Independent.
