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, three features making it amenable to many applications.
Safe and Continuous Power Beaming Microwave (SCOPE-M) is a United States Naval Research Laboratory (USNRL) project which delivers one kilowatt of electrical power at a distance of a kilometre using a microwave beam.
