I salute you! You are a better man than I to move this around;) But
your correct, you would have to melt steel BIG TIME to destroy it.

NO, why don't you try it small time and report back. say 100mm by
100mm plates. Connect them in parallel with your existing cap and see
if they smoke;) OOPs:, jacob's ladder.

At least until you outgrow your pole pig and resort to an EMP (the
HUGE electrical effect from a nuclear explosion in space) as a power
source;)

Try it on several small plates. Then scale it up.

Don't forget to smooth the edges after cutting;) or else there

H2 quenches well I hear;)
All fun aside: I like your idea; just start smaller and scale upwards.
