DARPA Wireless Power Beaming

DARPA is creating wireless power beaming to create a dynamic, adaptive, speed of light wireless energy web. The goal of the Persistent Optical Wireless Energy Relay (POWER) program is to design and demonstrate airborne optical energy relays. These relays are a critical component necessary to allow ground-sourced lasers to be coupled with high-altitude, efficient long-range transmission. Additionally, such relays will enable future multi-path wireless energy networks.

They are working to extend the range of power beaming and provide power to flying drones.
