This is wild. I never thought about how they separated gases from natural gas fields. The carbon footprint of each kg of that helium must be astonishingly large.
- citrin_ru 7mo agoI hope systems which separate helium: 1. have very good thermal insulation 2. use heat exchangers so separated gases can cool down incoming gas.
- wolvoleo 7mo agoWell yes but that's only if you consider the helium to be the only reason for the natural gas extraction which is obviously isn't. It's more of a byproduct in that sense.
