RE:Global supplyHelium can escape the atmosphere. When it's gone, we'll have to find a way to get it from space.
It's on the Strategic Minerals list for Canada and the US (I know it's not a mineral, it's a bureaucracy thing). Do I think there will sleays be some incentive for domestic helium production.
The Gazprom facility exploded and there's a slightly less favorable view of globalism now. I think we'll be ok even if prices come down from (what i assume are) all time highs
