That was my original question: is it technically feasible to make such a chamber from light enough materials (my first guess would be some carbon tubes supporting a carbon fiber tarp or something like that.

One could argue that it was too small (of course I imagine making a massive lightbulb would not make for a good solid structure, also glass is heavy). A hot air balloon does not float either if you lest it too much.

- alexisread 7y agoIt is worth noting that at a helium balloon's upper altitute, vacuum balloons would be more feasable as the air pressure allows thinner materials. Some sort of hybrid for say weather monitoring might be feasable.
