Scientists from Bistrol Robotics lab have found a way to power a cell phone using urine.
Dr Ioannis Ieropoulos from UWE Bristol say he is very pleased with the discovery as no-one has harnessed the power of urine to do this yet & this is one product you will have an unending supply of.
So far they have been able to create enough power to enable sms messaging, web browsing & make a brief phone call.
Dr Ieropoulos further states that the experiment is in the early stages & hopefully they will be able to charge a battery soon.
