content: Quote from: EEVblog on April 18, 2016, 12:26:27 pmNah - we can do better. I see a new IndieGogo campaign --- Along the lines of the Airing's "microblower" - why not a micro-micro hydro turbine that harnesses the energy from the stream of one piss to charge a cell phone? I bet the young guys who can take the bark off a tree could even charge 2 phones at once! Just need a catchy name and a slick marketing campaign.. Hmm - I think I'll go file the patent now....

content: Another catchy general-population friendly science news story "blurb" for daily consumption. Every day we hear of another one of these click-bait type research developments because the papers and online sites need something to fill their pages. The more bizarre it sounds, the more people will view it.While it may be of scientific interest, the practical use of this research will likely never actually be used for electricity production.Nevertheless, the science may feed into research on urinalysis, detoxification by bacteria, fertilizer development, waste treatment, biochemical processes, and other more practical developments. It's often the side benefits (however mundate they may be to the lay population) that will be profitable and practical.Generating electricity from urine for practical reasons other than science-fair type stuff? I don't think people in poorer parts of the world are going to find any use for this.... But the side-benefits in other areas of research....To me it sounds as practical as generating electricity from a potato:

content: Quote from: EEVblog on April 18, 2016, 12:26:27 pmHave you considered that the folks at Sky News might not have the technical competence to know how big a cubic metre is? The strapline on the article says 'miniature' fuel cell so I suspect that Sky turned cc or ml into 'cubic metre'. Given Sky New's grasp of the issues in politics or even of the simple truth, I suspect any units other than 'football fields', 'jumbo jets', 'olympic swimming pools' or 'elephants' might be beyond them.

content: Quote from: EEVblog on April 18, 2016, 12:26:27 pmDidn't one of the Mythbusters pee 1.5L all at once? I'm sure they didn't wait a whole day to get that.There is, however, a very practical way to use urine to make usable energy. Mix it with water to make fertilizer (if it's not mixed, it actually harms plants and can be used as weedkiller...), grow fuel crops with it (something high yield like switchgrass, not the greenwashed "ethanol corn"), then harvest the crops to make biofuel with. Growing food crops using that process also works but the (not very well justified) "yuck" factor sort of gets in the way...
