Gates Foundation en NCSU Student Engineering A Solution <p>A student at NC State is hoping to solve a pervasive problem in developing countries.</p><p>Tate Rogers needed an idea for his senior engineering seminar class last spring. The assignment – use the Gates Foundation Grand Challenge guidelines to develop an idea to help dispose of human waste in developing countries.</p><p>His idea was simple: encase a hand-held auger in a pipe, so that one person could empty a latrine, instead of needing a huge, costly truck. Rogers won a $100,000 Gates grant and is now developing a prototype.</p> Fri, 25 Nov 2011 18:30:00 +0000 Dave DeWitt 7182 at
