We are all waiting. Currently a claim has been made and some other claims that it could work both from modeling and replicating the process.
We are waiting for other labs to do proper peer reviews and verify the results. That still won’t mean it does what we hope it does just that the results are the same as what was found in the original claim.
So still a long way away from knowing what is actually possible.
Managing heat is a large part of circuit design. Superconductors can fundamentally change everything about it meaning far smaller much faster and more capable in every way. As an example 95%+ of modern CPU’s and GPUs are cooling related. The actual chips are tiny in comparison to the whole component.
I’ve used https://sequencediagram.org quite a bit as well. Its a text based sequence diagram generator and its been handy over the years.
Or you could just use all of the space for a sodium battery and fully charge it as it won’t need long term storage in that state.
