The important numbers : A … “nickel-based electrode to selectively and efficiently oxidise the urea. To break the molecule down, a voltage of 0.37V needs to be applied across the cell – much less than the 1.23V needed to split water. ”

And the molar concentration of urea in urine is?

If this technology works it will be bought by some giant corporation, patented and you won't see it again, like a lot of inventions that would be a detriment to one of the many cartels.

like that dude with the Hydrogen engine that was insanely better than the ones we have now. He's disappeared!

Would be much more concentrated in countries where convinent acces to clean water is severely limited. Just where this sort of engine would see deployment.

This isn't invented. It's just no one was stupid enough to do it in the past. Electrolysis uses more energy than it produces directly. That's why you will never see more than a few hydrogen cars in existence.

[io9.com] Oh, this? Just some teenage girls from Africa who invented a urine-powered generator.

That's right, a generator powered by urine. I hope there are people at DARPA right now being fired for not thinking of this.

Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen....1 Liter of urine gives you 6 hours of electricity.

and an NBC article somewhat critical of the invention: Link

So what's the catch?
post #18 of 55
The catch is they didn't tell you the total output in watts/amps. Can it power a smartphone for six hours or a house for six hours?

And I also discovered this is a repost but I did a better job tongue.gif

this is a repost. Also, someone analyzed the picture stating "How can it work"?
post #20 of 55
If it can be made efficient...wow. Of all the places for Energy innovation. I'm so Proud of them. I'm glad they have the opportunity to learn and excel compared to other places in the world. Kudos to them. Really brilliant kids. thumb.gif
