Bill Gates: Changing the way we poop

Even though waste disposal is something that we take for granted in America, 4 out of 10 people worldwide don’t have an environmentally friendly way to poop. Or health-friendly either – poop in the water can spread many viral and bacterial diseases, and can distribute some fun parasites too.  But of course we can’t stop pooping, and it’s not realistic or even possible to put in sewer or septic tank systems in every home (and without proper maintenance and care, those sewers and septic tanks may be worthless anyway), so what do we do? 
Last year, the Bill and Melinda Gates Foundation set out to answer that question – through a call for submissions for a completely reinvented toilet that minimizes water use and works efficiently and cheaply enough to put into homes worldwide.  Now they are going through submissions and announcing the winners.  Check out the new toilets and more about the Gates Foundation’s work at http://www.thegatesnotes.com/Topics/Development/Reinvent-the-Toilet-Challenge-Photo-Gallery

Would you put any of them in your home?
