Researchers have revealed a new system which transforms urine into electricity using a microbial fuel cell.

Just over half a litre of urine is enough for six hours of charge time, which can power a smartphone for three hours.




In breaking down and processing the urine they produce electrons which can then be harnessed into electricity

The team has already powered mobile phone but has now developed the technology far enough to fuel power-hungry smartphones.

Professor Ieropoulos said: 'We are excited to announce several global firsts - this development was possible by employing a new design of MFCs that allowed scaling-up without power density losses.

'Although it was demonstrated in the past that a basic mobile phone could be charged by MFCs, the present study goes beyond this to show how, simply using urine, an MFC system successfully charges a modern-day smartphone.'

The team has previously built a prototype toilet that generates 'everlasting' electricity from urine near a university bar.


The urinal is the result of a partnership between researchers at the University of the West of England in Bristol and Oxfam.


They hope the abundant, free supply of urine will make the device practical for aid agencies to use in the field.

Prof Ieropoulos added: 'One microbial fuel cell costs about £1 ($1.5) to make, and we think that a small unit like the demo we have mocked up for this experiment could cost as little as £600 ($900) to set up, which is a significant bonus as this technology is in theory everlasting.'

Somehow this make me feel like they are making fun of them, especially the clip with the car guy, and why do they show a guy and and a kid pissing on a door?

Dorset where else eh? >>> Thats ENGLAND<<<
while i appreciate the science involved in this i do see one problem
Calcum build up rendering the battery clogged up
Urine does contain Calcium and it does get deposited

Hint
kidney stones for one
I "Use an Incontance Bottle" ( for my Father ) and regularly have to DEEP Clean it ( Deposits of Something probably uric acid and calcium crystals )

Edit
experiment yourself Piss into a bottle
Seal it and leave it for a few days
See what deposits and accumulates at bottom of Bottle

Pretty sure I'm not going to do that.

Either way, this is intended for disaster relief, ie, temporary battery usage for a short term catastrophe. I doubt longevity will be an issue there.

They call that build up urine stone. I deal with it from time to time when plumbing. It breaks down pretty fast with the correct acids.

Dorsetknob do a google search for urinal acid, You should be able to fine something that will deep clean those plastic bottles very quickly, And provided you neutralise afterwards it shouldn't be an issue for your father.

Lets hope the battery doesn't develop a problem during one of it's "Recharging Cycles" and it becomes something like peeing on an electric fence....

I would think that the last thing on peoples minds would be to be able to power their smartphone for 3 hours, would be interested to see how that much (or little) power translates into being able to boil decent quantities of dirty/infected/polluted water to make it drinkable, otherwise they won't have any pee to use :D

Dude, a half liter of piss is A LOT of piss. You would need to drink a ton before being able to fill a liter bottle half way.

If longevity is out of the question with this device, why would I pay 900$ for it?, I am pretty sure i can come up with a far more cost efficient solution than a temporary light that cost 900$ per bathroom.

I missed the "cost $900" part. I thought this was going to be some kind of device air dropped to disaster zones. Clearly, reading on a cellphone has it's pitfalls. :roll:
