Re: Balloon? - WIND
900,000m3, works out to be a ~120m diameter balloon, quite big. Which raises the question, maybe you could just (...) stuff an airbag beneath it instead?
(The cables are quite horizontal, which means they're carrying quite a few times the weight of the observatory, I guess somebody has thought about the tradeoff. Maybe it's jerk versus relatively static force that's part of the issue?)
