Room-temp superconductors are the holy grail of electrical engineering. That’s what the unobtainium was that they were mining in the sci-fi film “Avatar”
These materials they are talking about are still at very low temperatures.
Yes, but compare that to the discovery of aluminum so many years ago and how expensive it was at the time to refine it.
Untill some enterprising young genius came up with a way to refine the aluminum oxide he had to almost pure aluminum metal using a totally new electrical application to do so.
Times change, and faster and faster it seems.
I’d love to play with room temp superconductors.
I believe we will one day have them.
Imagine the powerful static magnetic fields you could create in a small coil! Similar to what an MRI machine does with its super cooled coil.
Self sustaining magnetic fields of several T and at room temp.
