Power Beaming Phase 3
U.S. Naval Research Laboratory
March 4, 2021 | 3:39
The Power Transmitted Over Laser (PTROL) project safely and wirelessly transmits energy to a specific receiver. This has been a multi-year project. Phase III demonstrated PTROL is on the path to mount a receiver that’s light enough and powerful enough to be flown on a drone. Power beaming is undetectable by the human eye, quiet, and portable. Those three features make it amenable to many applications.

The first PTROL phase in 2017 used lasers to deliver energy through optical fiber for underwater applications and phase II proved large amounts of power can be transmitted over reasonable distances. Learn more about PTROL at https://go.usa.gov/xHWVr.
