Although known as residual substances produced by the body, urine or so-called urine proved to have a number of benefits.
In agriculture, the urine can be used as fertilizer that can nourish plants. Some people also believe that the urine can be used as medicine.
Recently discovered another benefit of urine. As quoted from Science Daily and Green Optimistic, a study revealed that the urine can be converted into electricity.
A Microbial Fuel Cell (MFC) - power generation systems that utilize bacterial interactions found in nature - a new kind, can turn urine into electricity at a rate that is unprecedented.
The tool has been designed at the University of Bath, Queen Mary University of London, and Bristol Robotics Laboratory.
"The world produces urine in large numbers and we can take advantage of the waste by using MFC, can revolutionize the way we make electricity," said study author from the University of Bath, Dr. Mirella Di Lorenzo.
So far, it has been a lot of research on how to generate electricity from urine using a variety of methods, but the results were not effective and cost
much.
Urine Fuel Cell, do not use expensive materials such as platinum, but it uses carbon fiber and titanium wire.
To make more power and speed up its work, researchers use catalysts of glucose and albumin, a protein extracted from egg whites. Interestingly, these materials can be found on food waste, other sources of bionergi.
In speeding up the reaction and produce more power, scientists use innovative ideas. They increase the burning electricity production tenfold by doubling the length of the electrons from the original model.
Then, they accumulate three MFC and earn ten times more energy.

The researchers also found a new Fuel Cells suitable for deployment in rural or remote areas, or in developing countries.
"MFC can be the main source of energy in developing countries, especially in poor and rural areas," said the study's lead author, Jon Chouler, from the University of Bath.
"Our new design is more expensive and powerful than traditional models. Devices that can generate electricity from urine can make a real difference by producing sustainable energy from waste," he added.
