It's easy: "room temperature" is about 300K.
That’s regular outdoor temperature in a lot of places. I wonder if there is any type of tech that is used in cold climates (or more on cold days) that would benefit from superconductors so they become more efficient when it’s most needed?
Oh - it has to be at 1atm and -20 of course...
That's about -10F, or -23C.
(And it would make a lot more sense to put that in the article. Most of us don't "think" in Kelvin.)
