I was joking in my other comment. But I remember seeing a study or rendering of the idea you described. Somebody out there is considering it seriously.
I believe NASA ultimately had to scrap the idea, but the cloud 9 buoyant cities idea is an old one, tracing back to Bucky Fuller and Earth, and it’s vastly more plausible than trying to make Mars habitable. Or even the Moon! Venus has Earthlike conditions if you exploit buoyancy to settle in the goldilocks area of the atmosphere.
Ha yeah I think I’ve read something to that effect. Fun idea at least, but holy shit would living in a floating Venusian city be scary; would you trust systems built by the lowest bidder to keep the city in the air so it doesn’t fall down into the Venusian hellscape? Also, better have great handrails 😄
