NRL Power-beaming Demonstrated on International Space Station

WASHINGTON (NRL PR) — International Space Station astronaut Jessica Meir completed the first U.S. Naval Research Laboratory power-beaming demonstration in orbit February 12, 2020, using relatively simple components suitable for STEM activities.

Meir showed how NRL’s LEctenna™, a light-emitting rectifying antenna, converted a wireless network signal, similar to home networks, into electric power. While the current generated and light emitted was a small amount, the setup proved the concept in space.
