> Another middle ground is it is a superconductor at -15°C (5°F). But it's freezer temperature that is much cheaper than liquid nitrogen or liquid helium.

I suspect this will make MRI machines much cheaper than they are currently and will radically improve the healthcare for many.

You got me thinking about the viability of superconductor-based EV motors that are cooled by compressed gas refrigeration; drink chillers might come standard on EVs since you'll be having beefier compressors than for just climate-control
