Drones Fly Forever: Laser Power Beaming Takes Flight

Laser-based wireless power systems are now moving from lab components to integrated flight systems, promising extended flight times for drones. PowerLight Technologies has developed a system capable of transmitting kilowatt-class power over distances approaching 2 kilometers, allowing unmanned aircraft to receive energy while airborne. This advancement means drones will no longer need to land for recharging.

The core of the system is an autonomous ground transmitter that precisely tracks aircraft, directing a laser beam to deliver power in flight. Described as an 'intelligent mesh energy network,' the transmitter communicates with the drone, adjusting for its velocity and vector. Testing has verified precision optical tracking, long-range power delivery up to 5,000 feet, and a robust safety system for mixed-use airspace.
