Two major benefits of orbital solar are that it doesn't have to deal

needs a lot more power than does Flagstaff, Arizona, but has a lot less
convenient desert.

Space based power sats will have to be in a very high orbit. I am
thinking Van Allen belts.
Otherwise the power sat will be passing over head about every 90
minutes ;-(

O'Neil suggested they be in geostationary orbits. That's above the
belts, right?

It's above the inner belt but pretty much in the middle of the outer.

Hasn't been an issue for any other kind of geostationary satellite
though so no reason to think it would be a problem with powersats.
