British Scientists Power Mobile Phones Using Urine
British scientists on Tuesday reported they had harnessed the power of urine and were able to charge a mobile phone with enough electricity to send texts and surf the internet.
Researchers from the University of Bristol and Bristol Robotics Laboratory in south west England said they had created a fuel cell that uses bacteria to break down urine to generate electricity, in a study published in the Royal Society of Chemistry journal Physical Chemistry Chemical Physics.
"No one has harnessed power from urine to do this so it's an exciting discovery," said engineer Ioannis Ieropoulos.
"The beauty of this fuel source is that we are not relying on the erratic nature of the wind or the sun; we are actually reusing waste to create energy.
"One product that we can be sure of an unending supply is our own urine," he added.
The team grew bacteria on carbon fibre anodes and placed them inside ceramic cylinders. The bacteria broke down chemicals in urine passed through the cylinders, building up a small amount of electrical charge which was stored on
a capacitor.
Ieropoulos hoped that the cell, which is currently the size of a car battery, could be developed for many applications. "Our aim is to have something that can be carried around easily," he explained.
"So far the microbial fuel power stack (MFC) that we have developed generates enough power to enable SMS messaging, web browsing and to make a brief phone call.
"The concept has been tested and it works - it's now for usto develop and refine the process so that we can develop MFCs
to fully charge a battery."
They hope the technology will eventually be used to power domestic devices. Philippine Star, July 18, 2013
In the Philippines, we only have to thank our sick system of education. It is mostly based upon the power of prayer and theology; hardly based on the power of science and technology.
It is, in this way, that we Filipinos know exactly what to do with our urine: we piss on each other on this earth down
here; specially for the greater glory of Jesus in heaven up there. Poch Suzara

Poch, don't feel too bad about our sick education system. They also have big problems in American schools despite the fact that billions of dollars are spent for public education. The Huffington Post reported last year that a 2009 study found that U.S. students ranked 25th among 34 countries in math and science, behind nations like China, Singapore, South Korea, Hong Kong and Finland. The picture in big cities is even more dismal. But then you can't blame religion. Bible reading and prayer in the classrooms were done away with more than 50 years ago. The Ten Commandments could not be posted on walls. Instead, the theory of Darwinian evolution was taught as if it was gospel truth. Peace and grace.
