This weekend, several Worldchanging team members are attending (and one is presenting) Pop!Tech in Camden, ME, where brilliant people and inspired ideas inevitably yield great, groundbreaking projects. One such project is documented in the current Fast Company issue, which spotlights WC contributor, Cameron Sinclair, and Architecture for Humanity. At last year's conference, Cameron met African social entrepreneur, Neema Mgana. The two discussed the need for a clinic in Ipuli, Tanzania. Fast forward a little bit -- add in the additional input of an environmental engineering firm in Boston, a design firm in Paris, and local Ipuli residents -- and ground has already broken on the fifth clinic in rural Tanzania. Mgana is at this year's conference to present the project's progress.
