sunshade? maybe with a really thin reflector, mylar or gold, electrostatically deployed?

i also want to do an unfolding/deployable fusion reactor i found this paper. they’re pretty optimistic about launch costs, and they need to use radiation pressure for station keeping, and it still comes to trillions. i think cloud seeding in the upper atmosphere is much cheaper
