Scientists working at England’s Bristol Robotics Laboratory have developed a technique for converting urine into electrons, enough to power a cell phone.
The research team has developed microbial fuel cells that consume carbohydrates, nitrogen, potassium, phosphorous, and other compounds that would otherwise go down the drain. If you can get past the gross-out factor, the benefits to places in the developing world and elsewhere that lack reliable (or affordable) sources of electricity are obvious.
The project reminds me of another one showcased at Maker Faire Africa last year: a urine-powered generator.
There’s an added benefit of the microbial fuel cell technology, too. According to researchers, passing the urine through the fuel cells “cleans” it so it can be safely discharged into the environment, eliminating the need for wastewater treatment. Maybe sewage plants could double as power plants. Pee pee becomes a win-win.
If the output of the fuel cells could be expanded, what applications can you imagine for this technology?

Livestock yards just became power plants.
Fools waste a fortune in natural fertilizer for now but higher petroleum prices will catch up with them. America is challenges now by Chinese bids for oil and will have to think before leaping from here on in.
This reminds me of Waterworld :)
Urine also has remarkable qualities as a fertilizer yet we in the Western World are fool enough to pay for petroleum based fertilizers, for now anyway?
