And how do you suppose to do that?
Beam the power from space like they do in Mirai Shounen Conan? Or space shuttles with batteries? Or a giant cable that somehow doesn't break?
It's not possible.
Naw, you just beam it back to earth as a laser. That way you could highjack the signal and fill a house with popcorn kernals a to start a huge neighborhood block party.
That’s a real genius plan.
Deathray!
Feasible? Only time will tell. Possible? Caltech did it two years ago. Look up MAPLE. Wireless energy transfer to/from space was achieved.
At what scale? Milliwatts? Watts? On cloudy days?
This seems very much to fall into the "technically" possible, but impossible to scale realm.

Microwaves or even Masers. This is nothing new, lot's of studies and experiments. It's not infeasible, efficiency not that bad either. But solarpanles on earth have only advantages, especially integrated in roofs or walls.
It would probably be done with lasers. Its not perfect tech rn but it is possible. If not the most efficient for its price
