Awesome but vague headline from CalTech on a space based solar energy transmission breakthrough


Any thoughts on this? I’ve read into this technology before, but the last I read the technology was incredibly far off from something like this. At the time that I was reading it, the record for meaningful wireless power transmission was like 2 miles.
The paper apparently hasn’t come out yet, so no numbers on transmission Loss are available yet. The only mention of the amount of power transferred was the part of the article that mentioned that they lit some LEDs with the transferred power.
If it were from anywhere less prestigious than Caltech, I wouldn’t give much thought to it. But I can’t imagine them publishing something blatantly bogus. Does anyone know anything about this? Is this actually promising?

  1. They lit some LEDs with a radio receiver and a rectifier. You can do the same if you put an energy scavenging device next to a starlink antenna when the satellite overhead is transmitting.

    Nothing of note happened.
