Nitrogen is N2, though. Liquid nitrogen is cheaper than liquid hydrogen.

I was able to find "1 gallon of liquid nitrogen costs just $0.5 in the storage tank". That would be about $0.12 per 1L of N2.

Edit: Didn't read the OP carefully... Am idiot. Anyway, maybe someone reads something new to them.

Nitrogen won't get you below 10°K, tho. It's solid below 63°K (-210°C).

You know things are getting expensive, when superconductors are rated "high temperature", when they can be cooled with LN2...

Helium (He2) is _practically finite, as we can't get it from the atmosphere in significant amounts (I think fusion reactor may be a source in the future), and it's critically important for medical imaging (each MRI 35k$/year) and research. You also can really store it long term, which means there are limits to retrieval/recycling, too. I sincerely hope we won't start blowing it away for porn and Instagram.
