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.
