Can you actually extract a significant amount of Helium from atmospheric air? I was under the impression that it was far more likely to escape into space because it's so much lighter than the other gasses in our atmosphere.
- Symmetry 10y agoLosses to space is the reason we have relatively so little but in absolute terms that's still a huge amount. Helium makes up 5 millionths of the atmosphere. EDIT: Thanks for the correction.
