What’s the point of floating up there if you can’t actually land because the challenges to do that are immense?
What about the whole sulfuric acid problem?
It’s not as much the feasability of floating in the upper athmosphere of Venus that I was worried about, it’s that getting anywhere interesting from there is either enormously hard (hot sulfuric acid soup to go down) or useless (back to orbit from where you came and where you could just have stayed) and probably no fun by itself and unecessarily risky due to the sulfuric acid.
Tourism-wise a Moon base makes a lot more sense and is a lot more feasible for now than that, IMHO, whilst it also doesn’t seem to make sense to set up a floating base on Venus’ athmosphere to extract resources from it (because on Earth we’re hardly low on CO2 or sulfur).
PS: Thinking about it, a floating station on Earth’s athmosphere would probably be more fun than that also.
