Your pee will soon have another use, apart from just watering plants when you can’t find a restroom. Pee power is a revolutionary technology that could use urine and convert it into useable electricity! A team of scientists in University of West of England in Bristol has come up with a way to exploit pee, using a simple science principle, and they have designed an effective way to put it to use.
Pee power works on pee cells!
The model they have adopted is fairly simple. As we know, urine is nothing but a solution of certain compounds such as urea and salts. Basically, whatever our body doesn’t need, it passes out as pee. Microorganisms often use such waste products from bigger life forms to derive nutrients for themselves. They are so efficient in getting what they want that they convert almost 96% of all the waste into useful product for themselves. Using these same microorganisms, the team came up with microbial fuel cells, or MFCs.
Maybe pee power could work for cars too someday
While not as efficient as the microorganisms themselves, these cells can still charge smartphones and they can also provide energy for LED lighting. The lead researcher, Professor Ioannis Ieropoulos says that the team has also powered DC pumps, DC motors, micro controllers and sensors. This gives hope to the team that maybe after improving the efficiency of the MFCs, they could probably power electric cars too. And the best part is that the byproducts of pee power are cleaner that the chemicals in urine, making it eco-friendly too!
Pee power is already in public testing phase
To test just how useful pee power could be, the research team installed a special urinal at the Glastonbury music festival and it was able to keep interiors of the stall lit using LEDs. It is believed that pee power could be used in developing countries and in refugee camps. Another interesting thing the scientists discovered about pee power was that it works better with urine that has a high alcohol content. Who knows in the near future, when you’re completely wasted at a bar, your pee could light up someone’s home.
