Most global-poverty workshops share a tedious format -- lots of yakking, little action. But at this monthlong MIT-organized event, delegates won't just lament third-world woe; they'll create real devices to improve life for the bottom billion. At last year's summit, inventors from 20 nations built 10 cheap, low-tech prototypes, including a hand-cranked machine for grinding corncobs into fuel and a chemical-soaked nipple shield that prevents HIV transmission between a breast-feeding mother and child. Our dream invention? A device that produces corruption-free leaders. -- Theunis Bates
