Is there even enough commercially-available helium in the whole world to support this structure, much less a 100+ km tall version?

- randallsquared 17y agoWhen you're talking about floating structures measured in miles, it doesn't matter. You could do it with small temperature differences. You could float a half mile geodesic sphere with only a degree or two of temperature difference and ordinary air.
- Semiapies 17y agoHmm, good point.
