The application to drones seems most clear: beam drones some extra power as needed. Or continually!
I wonder how big that receiving apparatus is. Whether the receiver is gimballed, or whether the drone itself has to fly a heading to aim at the sender: TBD.
Why not just beam power down the optical fiber? Optical fiber is exceptionally clear and works in fog and rain
How about drones with a solar panel case? Would require a sunny day to work at all though.
Tiny nuclear reactor?
Seems like that has a high chance of frying sensors on sats flying behind the drone though

And have a great opportunity to drill some holes in birds heads.
Sorry I really fail to recognise how beaming 1kw of excited particles is a safe thing to do just like this…
