Yes, I agree superconducting-ring-as-battery isn't very practical at all. I was shocked by how little it can store. I was picturing that it could just become like a super super massive power line and store as much as you want, electrons are small, are they not going to fit? I thought any number of electrons will fit pretty much, it'll just keep increasing the current racing through it (not saying my EE training is the best), which I thought would be a lot. I didn't know there is a heavy magnetic component that is the limiting factor of all this. In some ways I guess it is still a lot of storage, but it isn't useful for anything. Still cool.
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 :)
Thanks for sharing the link, interesting page.
