How do Helium cannisters expire after a year? If you don't use it, it should last forever. Centuries even? Is it some kind of corrosion over time?

>>16840821 (OP)
Read up on why blimps need a constant refill.
Some kind of voodoo about atoms slipping through holes.

literally googlable question, this post made me irrationally angry

>>16840821 (OP)
No, its that you'd have to perma seal the cannister to stop it from leaking out

>>16840828
Not an argument.

>>16840821 (OP)
Helium (and Hydrogen) are smallest atoms/molecules which means they can pass to any seals and even diffuse through solid matter. That's why hydrogen corrosion is a thing. Hydrogen penetrates steel and sticks inside making it brittle

Hydrogen is so based and ungovernable.

That is why hydrogen is a meme and should stored as methane instead.
All you need is an efficient way to extract CO2 from air.

Your car's fuel tank will work great for this.

>>16841636
why dont we contain it with electrical shocks so it stays in line

>>16842215
Hydrogen is based, it's the absolute state of material science that's a total meme.

>>16842215
Since hydrogen is sourced from methane it is already being done sort of
