Campers Could Soon Charge Cell Phones With Pee

Stuck in the woods with no way to charge your cell phone? Soon, you might be able to solve the quandary with your own urine. Researchers in the United Kingdom have figured out how to use waste-eating bacteria to produce enough electricity to send a few text messages and make a call, with the output steadily improving.

Here’s what Dr. Ioannis Ieropoulos of the University of the West of England, part of the team who worked on the project, explained to the Independent:

“The beauty of this fuel source is that we are not relying on the erratic nature of the wind or the sun; we are actually reusing waste to create energy. One product that we can be sure of an unending supply is our own urine.”

As of right now, the urine-to-electricity device is about the size of a car battery, but it’s expected to get smaller and more portable. Besides charging mobile phones, they could also be installed in bathrooms, allowing us to harness our urine power day and night year-round. In a few years, it might be normal to see pee-powered charging stations at National Parks — or, visitors could just plug in at a luxury hotel nearby.
