Flat battery??? Power your mobile phone with URINE

Spending a penny to make a call home. that could be the future... one Wee could be enough to send an emergency text message or make a call, after scientists discovered a way of recharging a mobile phone with urine.

Researchers at the Bristol Robotics Laboratory harnessed an electrical charge by passing urine through a stack of microbial cells, which reacted to compounds including chloride, sodium and potassium.

The resultant charge was enough to make a brief call on a Samsung phone, send a text message or browse the web, the Royal Society of Chemistry journal reported.

The microbial fuel cells convert energy, which turns organic matter directly into electricity, via the metabolism of live micro-organisms.

The scientists now plan to develop the technology to be able to fully charge the handheld device.

Could the 'smart toilet' be the next green tech we all need to surf with the ipad sitting on the loo?
