house design nigeria
http://www.overunity.com/13101/urine-powered-generator-from-africa/ this is a new system designed by 4 schoolgirlsfrom nigeria, africa with the help of their teacher toget an electrical generator system running on just only urine ! they used electrolysis to split urine ( pee) into hydrogen and clear it up via a liquid borax solution andthen run a generator to produce the electricity torun the electrolysis... so it seems this is a selfrunning system onlyusing up the pee !!! urine-powered cars, homes and personal electronicdevices could be available in six months.
using a nickel-based electrode, scientistscan create large amounts of cheap hydrogen from urine that could be burned or used infuel cells. one cow can provide enough energy to supply hot water for 19 houses.one molecule of urea, a major component of urine, contains four atoms of hydrogen bondedto two atoms of nitrogen. if you place a special nickel electrode into a pool of urine andapply an electrical current, hydrogen gas is released.a urine-powered vehicle could theoretically travel 90 miles per gallon.using urine as a source of fuel may sound like a bit of a stretch, but it's actuallyquite ingenious. it's based on the use of hydrogen, the mostabundant element in the universe. hydrogen
has been called "a renewable, versatile, simplesustainable domestic energy" because it can be produced from tap water to generate powerfor homes and cars. however, one of the hurdles facing this alternativefuel source is that hydrogen gas requires high pressure and low temperatures to be stored.it becomes somewhat easier to store when it's binded to oxygen to create water, but eventhen it still requires large amounts of electricity to be released.the ohio university scientists who developed the urine technology found that attachinghydrogen to nitrogen in urine allowed it to be stored without the strict requirementsof ordinary hydrogen, and allowed it to be released with less electricity (0.037 voltsversus 1.23 volts needed for water).
so it is very interesting that you can alreadysplit urea at 37 millivolts... no wonder this urine splitting could be madeso efficient in an electroylsis cell ! you just need so much less power for splittingpee than water... link to this video. https://www.youtube.com/watch?v=f48zowfhvfa
