A great experiment is under way in Uganda. An industrial skyline of water and cell towers hovers over sturdy mud huts and small farm plots. Schools and health centers are built from brick, slathered in concrete, and fitted with glass windows. Taps run freshwater, and small solar panels power streetlights, as well as radios blasting music from barbershops, televisions airing soccer matches in community halls, and cell phones snaking from charging stations in shops.
