There's some interesting innovations in infrastructure-less transport: 1. low cost UAV's - have been used in africa to transport blood samples and meds between hospitals and cities. the MATTERNET is a project that on scaling a UAV transport network in africa, using UAV's , currently probably for small weights , but it would probably increase in the future. But the UAV industry is improving in rapid pace, because of military innovations, so it's a good place to be. There's also a lot of open source innovation there, radically reducing the costs. 2. There's some work being done on airships(and plane airship combo) for the army, and airships for commercial transport for areas with no infrastructure(oil fields, etc.). might also fit africa. 3. There's a company working on a low cost jeep , fit to the the African muddy roads. It's can also cheaply supported by current african repair networks.
