PowerLight hits its targets with laser power beaming

Wireless power transmission has been the stuff of science fiction for more than a century, but now PowerLight Technologies is turning it into science fact … with frickin’ laser beams.

“Laser power is closer than you think,” PowerLight CEO Richard Gustafson told me this week.

This is much more than a lab experiment: Gustafson said his company, which is headquartered in Kent, Wash., is wrapping up a $9.5 million demonstration project for the U.S. Naval Research Laboratory.

In 2019, PowerLight showed that its power-beaming system can transmit 400 watts of power — enough to fire up an array of lights, laptops and a coffeemaker. In 2020, it followed up with a demonstration of a lightweight power receiver suitable for drones. The project proved to the Navy’s satisfaction that PowerLight’s laser system could be operated safely without endangering people who get in the beam’s way.
