Mark Zuckerberg has shown off the lasers that it hopes could beam the internet from a fleet of giant drones.
The firm is building a fleet of drones capable of flying at 65,000ft (19,800 metres) and staying in the air for months.
Now the first details of their communication system have emerged.
“As part of our Internet.org efforts, we’re working on ways to use drones and satellites to connect the billion people who don’t live in range of existing wireless networks,” said Mark Zuckerberg.
