ELI5: What could theoretically happen if the new fusion reactor has a problem when it's turned on in two days?
gpt
Well, first thing, the new fusion doesn't even fuse (for the moment). It runs on simple non-fusing plasma (hydrogen).

Anyway, the worst that could happen is some short circuit or cooling failure in the superconducting magnets, which results in a few million in damages and a bunch of very disappointed scientists.
