superconductors

The heat problem sounds like they need to be using superconductors or some means of high-efficiency cooling.

The superconductors in the board needs to be extremely cold, and the ground needs to be covered in magnets.

Edit: The significance of this is that superconductors that operate at room temperature did not exist.

The first superconductors experiments used Helium at 4K, so they were only a laboratory curiosity.

And dont hold your breath on room temperature superconductors, it may not even be possible...

In the 80s high-temperature superconductors were discovered, which were 'impossible' by previous understanding.

The reason high-temperature superconductors are important is because they allow very strong magnetic fields, such as the kind used in MRI scanners in hospitals.

From the electron's perspective, all superconductors are sort of perpetual motion machines.

It's not as if high-Tc superconductors are unattested in the literature.

Another cool application is the superconductors in the NMR devices.

> The board uses liquid nitrogen-cooled superconductors and magnets This sounds like it uses the Meissner effect.

Not knowing much about superconductors, I had no idea what to look for.

And even low-Tc superconductors looked "impossible" under the physics of their day.

Cheap superconductors would also be a "black swan" for energy markets.

Ultrasound is one of those "safe" medical operations that you don't think too much about because it's not chemical, radioactive, or built out of superconductors.

For example: - Mechanism for baryon asymmetry - Mechanism for ultra high energy cosmic rays - Mechanism of high temp superconductors - Black hole information paradox - Finding solutions to the Schrodinger equation in various situations You might mean something very specific when you say "Fundamental physics" though.

Superconductors have zero resistance and so they don't heat up when current goes through them.
