What you are saying is that helium is not gravitationally bound to Earth. That is correct.
But even if it were, it would not make any difference. Any gas that leaks in the atmosphere is economically lost. Take Neon. I just googled and found out that liquid neon is a cryogenic refrigerant (like liquid helium). Do you think the neon lost through leaks can be recovered any more than the helium lost through leaks?
- ars 3y agoNeon is condensed out of the air, any neon lost is just there in the atmosphere waiting to be re-condensed by someone else. The difference is Neon stays in the atmosphere, while Helium floats to the top and is lost.
- _ihaque 3y agoNeon is produced from (cryogenic) separation of air, so, yes?
- credit_guy 3y agoWell, fun fact: there is more helium in atmosphere (5.2 ppm) than methane (1.8 ppm). And it's not much less than neon (18 ppm). [1] https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-handle-on-carbon-dioxide/ https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-...
