Humans are Racing to Control the Weather—Using Drones, Lasers, and Salt
In a gold-trimmed command center on the outskirts of Abu Dhabi, scientists are seeking to wring moisture from desert skies. But will all their extravagant cloud-seeding tech—planes that sprinkle nanomaterials, lasers that scramble the atmosphere—really work at scale?
That dust—actually ordinary table salt coated in a nanoscale layer of titanium oxide—will be carried aloft on updrafts of warm air, bearing it into the heart of the fluffy convective clouds that form in this part of the UAE, where the many-shaded sands of Abu Dhabi meet the mountains on the border with Oman. Sheikh Mansour bin Zayed Al Nahyan, a member of Abu Dhabi’s royal family—currently both vice president and deputy prime minister of the UAE—thought cloud seeding, along with desalination of seawater, could help replenish the country’s groundwater and refill its reservoirs. Youssef Wehbe, a UAE program officer, gives me a cagey interview about the future vision: pairs of drones, powered by artificial intelligence, one taking cloud measurements and the other printing seeding material specifically tailored for that particular cloud—on the fly, as it were.
