Caltech to launch space solar power technology demo into orbit
I'm super ignorant on physics and whatnot; but wouldn't it make more sense to use airships covered with solar panels at 5k-6k meter altitude? Thin solar is now a thing, and I'm quite sure that there would be a viable way to engineer an airship in such a way. One could even use graphene aerogel instead of helium or hydrogen as the lighter-than-air filler.Is this a really dumb idea? Any of you with a more relevant background could tell me where this could be so wrong?
