I'm wondering if it is possible, super cooled superconductors exists, but could room temp be fabricated?
Seems like something we have never observed, and a strong understanding of Magnetism needs to be fulfilled.

It's very much outside of my background in physics, but I don't think there is enough to say that it's impossible. Historically, when we get stuck on a problem like this, it mean we're probably going about it the wrong way, or there's something about it that we don't understand. Something totally different needs to be tried.
