Last year, Mark Zuckerberg and Facebook surprised many when it revealed that it joined forces with other major tech companies to bring internet access to the two-thirds of the world thats offline. Today, Facebook confirmed rumors that engineers are working on developing a fleet of solar-powered drones that can beam internet access down to people in remote regions of the world. According to todays announcement from Internet.org — the organization that Facebook, Ericsson, Nokia, Qualcomm, Samsung, and others joined last year to help spread internet access — the drones would fly autonomously for months at a time at an altitude of 20,000 meters (roughly 65,000 feet). It may sound crazy, but scientists have already made similar solar-powered planes.
