Build a big solar array in orbit, the idea goes, and it could collect enough sunlight (unfiltered by atmospheric effects or clouds,) to generate a powerful beam of microwaves.

That brings back some nostalgia. I remember playing one of the early Sim City games and that was one of the types of power plants you could set up. It had a small chance to malfunction, causing the beam to miss the collection station and set everything in the surrounding area on fire.
They are talking about beaming power to drones, but thinking a bit larger, I wonder if it be feasible to have a high power laser transmit energy to a satellite and then have a cluster ala Starlink act as an relay to direct the power potentially anywhere on earth. Maybe you could power airplanes from space? Sounds like Sci-Fi, but apparently all the components and technologies exist, and people must have been working on it for a while, when they just letting the public in on it.
Didnt' China try to do this a few years back but was shutdown for some reason? Also, this would double as a great military weapon so I am sure that is being assessed as well.
