Climate change is a worry and it has been an issue that concerns us all. Resources are depleting and the need to find sustainable sources of power is ever-increasing. The technology is there to harness energy from sustainable sources but the money to fund these projects is not – especially for people living in remote regions and in poor areas. So, rather than think outside the box one university has started to think “inside the box” and focus on relying on a source of energy within us – urine.

Electricity can be harnessed from faeces too. The University of Bath has developed tiny, microbial fuelling cells that can help extract bacteria so it can generate power and electricity straight from the organic matter direct.

The latest design prototype can actually produce two watts per cubic metre from one tiny fuel cell. That will be enough power to generate a full charge to a couple of eco-friendly business mobile phones. Greener business mobiles could be powered in the future by our very own number one and number twos.

Inside the Bath University’s Department of Chemical Engineering, they have a dilemma – or to put it more accurately, a trilemma. The sustainable power source has to be: • Secure • Environmentally friendly and sensitive to the world around us • Economically viable

Taking full of advantage of “pee power” is the only single solution that addresses this trilemma. It takes full advantage of indigenous resources, and that includes our pee, so using planet free mobile phones for the future can be a reality if the research at the University of Bath gets some serious consideration.

The power of the pee can be an excellent idea for people in developing countries. In many parts of Africa and central Asia, there are huge costs involved in generating CO2 free mobile phones from wind power, hydrogen power, and solar panelling. There simply aren’t enough funds to get these projects off the ground in developing countries and using microbial fuel cells instead – to generate electricity – you could also get rid of a lot of waste in the process.
