By Shaoni Bhattacharya. The first urine-powered paper battery has been created by physicists in Singapore. The credit-card sized unit could be a useful power source for cheap healthcare test kits for diseases like diabetes, and could even be used in emergency situations to power a cellphone, they say.
The secret ingredient for developing cheap, effective batteries could turn out to be urineaccording to researchers from Stanford University. In a new study, published in the journal Proceedings of the National Academy of SciencesStanford physicists describe a battery that works efficiently using urea, the central component of urine, after water. The battery is designed to work for grid storage of renewable energy electricity.
Scientists have developed a way to turn pee into electricity. And there's plenty where that came from, they point out. Cheap, disposable, and renewable, urine-powered batteries may be the perfect power source for disposable healthcare test kits called biochips, the researchers say.
When most people think of bacteria and urine together, chances are good they think of a not-so-pleasant infection. For researchers at the University of Bath however, unifying these two thoughts led to the development of a battery that could harness "pee power" to bring energy to parts of the world that might not otherwise have access to it. When such a reaction occurs, electrons are swapped around between molecules and electricity is produced.
A scientist at Ohio University has developed a catalyst capable of extracting hydrogen from urine. That's right. Now you can fill one tank while draining another.
Batteries can be as simple as the lemon juice-powered toy car you made in high school, but developing a commercially viable battery from readily available and cheap materials has proven an elusive goal for many a researcher. The latest development on this score comes from Stanford University with the introduction of an aluminum-ion battery that uses an electrolyte made of urea, the main component of urine after water. This isn't the first battery to use pee power.
Scientists at the University of the West of England have created microbial fuel cells that have the capacity to fully charge a smartphone, only using urine. Microbial fuel cells take bacteria and turn organic matter into electricity. Though there are other ways of doing this, microbial fuel cells are the most efficient since they can run at room temperature and pressure.

How do microbial fuel cells work and what is the potential of urine and wastewater as a viable energy source? While Robial was only founded in Novemberthe concept has been in the works for a long time and could be revolutionary, having advantages in both renewable energy generation and the recycling of wastewater.
Smartphone batteries keep getting stronger, but new devices also require more power for high-definition displays and faster processors. The result is that people still have problems keeping their mobile devices charged throughout the day. Professor Ioannis Ieropoulos, a researcher at the University of the West of England, has created a way to recharge batteries without relying on electrical outlets.
Researchers at the University of Bath have developed a miniature microbial fuel cell MFC that uses urine to generate electricity, making it a cheap, renewable, and carbon-neutral energy source—something that would be of particular benefit to areas of the world where energy is scarce or inaccessible. When the reaction occurs, electrons are exchanged between molecules. Electricity is generated when the reaction takes place in a closed system with an anode and cathode. Currently, one pee pee fuel cell will generate 2 W per cubic meter—enough to power a small device, such as a mobile phone.
