The authors of the new development are a team of researchers at the BioEnergy Center in Bristol. Scientists have already demonstrated the installation. They showed that with the help of urine, low-power energy can be obtained. The energy can then be used to power light bulbs, mobile phones, and robots. The solution was said to be capable of generating 300 watt-hours of electricity during the five-day festival. This would be enough to power one 1 W bulb for 300 hours.
The device is based on what the company calls microbial fuel cells. Microbes feed on organic matter, then chemical energy is obtained, which, in turn, is converted into electrical energy.
Now scientists want to reduce the size of the fuel cells, which have turned out to be too large so far.
