Drones // 

Dr. Adam Watts of the Desert Research Institute is standing by the side of the road near Donner Pass, shouting over the wind into his phone to talk about a recent test flight. “We built a robot that can fly itself and bring more water out of clouds,” he says, capturing the technological promise at hand in just a few words. Together with Nevada's Drone America, the team flew a cloud-seeding drone beyond the pilot's line of sight. It's the next step in a gradual and ambitious process, aimed at solving a decades-old problem: can the desert pull more water from the sky, and can it do so without injuring anyone along the way?
