Keller Rinaudo Cliffton thinks we’re already experiencing the technology of tomorrow, just that it’s not evenly distributed... About a decade ago, Keller transformed his smartphone robot company into Zipline, which today orchestrates on-demand drone deliveries all over the world. Zipline got its start delivering critical medical supplies to hospitals in Rwanda: a testament to Keller’s belief that innovation is already improving lives outside the U.S. This week on How I Built This Lab, Keller recounts the ongoing and often challenging development of Zipline’s delivery drones. Plus, how Zipline is now chasing the commercial market, and could soon be delivering packages from stores like Walmart within an hour of a customer clicking “purchase.”  This episode was produced by Carla Esteves and edited by John Isabella, with music by Ramtin Arablouei.
