It 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.
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.
