The failure modes would mostly be the same as for the big ones: sucking in metal chairs if you're not careful.
I hope I never find out which is worse of chairs vs. piercings…
I hope I never witness a resonance cascade, let alone, create one.
Sign me up, I'd like to be one of the biped critters with giant mouths on their stomachs. Short pipeline, very efficient.
That description sounds like the F'lickta in Marathon 2, was it also something in Half Life?
They are already superconducting and using liquid helium to cool. They have failure modes of spilling gas out into the room (patient and operators have to evacuate.)
At least now the silo doors will open by sliding on superconductors.
