I beleive it is possible to generate electricity from urine, but I suspect the technology may be beyond the ability of those schoolgirls it is the after all
I'll keep an open mind then..

good discussion.. a change from A frames and the like

Ah, the Daily Mail. They did a hygene study into the amount of items we touch in a day that transfer sh*t to our hands. I was ready to question this, knowing how clean our home is,......when I realiased I had just been holding a Daily Mail.

Original Source of the news -
http://makerfaireafrica.com/2012/11/...red-generator/

Other info supporting the feasibility and some of the science, picked out from some of the posts,
its not a new idea but is the first practical use...and certainly in Africa

Gosh - with what I produce overnight I could likely power Bed'th and some parts of Ash Green.

Interesting, bacterial action. Wonder if the hydrogen production would be higher if you was diabetic when your blood glucose was so high (ie in excess of 10% which causes damage to organs etc) and therefore, the glucose spills over into your pee?

I ask this because the NHS and the Daily Mail etc are always telling us how much diabetic complications are costing us all; this way maybe the hospitals treating the uncontrolled Diabetics could recoup the cost on what they saved on electrickery !



Much cheaper than educating the poor sods, after all ......

It was debated long and hard somewhere else, the point seemed to be the hydrogen was not fuel but a catalyst to improve the diesel combustion.

It did not look impossible but, as always, if had worked why weren't the manufacturers building it in ?

Yes indeed..

IIRC .. One of the members (on RVOC) had it installed free by a company for testing purposes with the condition that if it improved the MPG he would pay for it .. After testing for several months there was no improvement, so it was returned..
