Can they not work with extremely strong magnets as mentioned by Mathsisfun?

[Mathsisfun15]

The energy required would be significantly less with superconductors. You can but why waste heeps of energy?

except heaps of energy is required for cooling as well

Not as much as lifting it with magnets

 

[Mr_Kap]

But apparently there is concern for having large magnetic fields produced hence is a safety concern and lead to the very first superconducting train in America to be shut down.

LOL so what?
