lots of fun techniques, a common one for getting down low enough where other methods become practical is stirling cryocoolers, and those are even on ebay for a few thousand (cascade refrigeration systems, and joule thompson coolers are also used), way down past that theres stuff like weird magnetic coolers, and dilution coolers All very interesting, reading about exotic cooling methods is fun.

That’s a very big refrigerator

And why in the absurd fuck would you use Fahrenheit for that.

This is the right answer. It’s a big cryogenic refrigerator called a Dilution Refrigerator. It’s fancy stuff. Needs Helium-4, which is more common, and Helium-3, which mostly comes from nuclear production.
