New York Times: “Because of the rapid spread of cellular phones, mobile technology has previously been used to address a variety of problems in the developing world, including access to financial services, health care information and education. But toilets were another matter….Building on a process that had previously been employed to address problems in supplying clean water to people in poor areas, the World Bank turned its attention to sanitation. Over six months last year, it solicited ideas from experts in the field, as well as software developers. The process culminated in early December with the actual hackathon — two days in which more than 1,000 developers gathered in 40 cities worldwide to work on their projects….After the event in Washington, the winners of the hackathon are set to travel to Silicon Valley for meetings with venture capitalists and entrepreneurs who are interested in the issue. The World Bank does not plan to invest in the projects, but hopes that others might.”
