Imagine a world where drones fly the skies — but the drones aren’t for warfare. Instead they’re delivering packages, leapfrogging traditional infrastructure to create a world connected by tiny, nonviolent drones. In the U.S., such drones could replace the aging postal system; in developing countries, the drones could connect rural communities to markets, alleviating poverty and delivering badly needed supplies and medicines. […] A case study done by the Matternet team in Maseru, the capital city of Lesotho in southern Africa, showed that the entire 140-kilometer capital could be connected by a drone network for $900,000. “In contrast, the cost to build a 2 kilometer winding road is a million dollars,” Santana said. For cash-poor countries with little infrastructure like Haiti and the Dominican Republic, the cost difference is crucial, and the infrastructure Matternet provides — a whole network, rather than one road — could be lifesaving, she added.
