Research shows that urine, an alternative source of energy, is used in miniature cells to help power mobile phones. Unlike other sources of electricity, such as platinum, urine is relatively cheap and readily found. The microbial cells cost £1-£2. This invention is helpful to people living in remote areas where other sources of electricity are fairly expensive. Urine is organic in nature and, thus, does not emit any carbon to the atmosphere.
To generate electricity for electrical devices, urine must pass through the miniature cells. The microbial cells, in turn, naturally convert organic matter, in this case urine, into electric energy. Such electricity is then used to power devices, such as mobile phones. This renewable source of energy can also be stored. The fuel-powered miniature cells measure one inch square. This is the reason why they are used in mobile phones.
The cathodes of these cells have carbon catalysts that are made from glucose and a protein from egg white; ovalbumin. Unlike normal electrodes, which are 4 millimeters long, electrodes in these cells measure 8 millimeters in length to increase power output. One microbial cell can produce two watts per cubic meter, which is enough for a mobile phone. Research is ongoing to increase the cells’ power output. This will increase performance of mobile phones and other related devices. High power output will also support powerful mobile phones.
Conclusively, urine is a cheap, safe and eco- friendly source of electricity. Researchers from a number of leading institutions have come up with ways to generate electricity that is used to power mobile phones from urine. Renewable, or indigenous, sources of energy are a revelation to people who cannot afford traditional forms of electricity or those living in remote areas. Mobile phones using urine as a source of power will help revolutionize lives in third world or developing countries.
