Wheeeee Loop – A Superconductor Used Like a Battery (stateofutopia.com)

I wanted to see how much energy a superconductor could store if it's being used like a battery (with the electrons just going round and round in a loop with no resistance - wheeeee!) This tool helps model that. See how high you can get the stored energy to go.

As you can see from the numbers, this is not a very practical solution for any of your energy storage needs. Still fun to play with, so I thought I'd share.

So your default model (1 m diameter) stores about the same energy as ~100 mL of gas? (~3 MJ)

Might be interesting to have a button to fill in the parameters for Commonwealth's magnets https://cfs.energy/technology/hts-magnets

I agree it isn't very practical :)
