the engine pipes are horribly broken

[Rhydic]

well the thing i'm concerned about is pipes not realizing they're broken and need to vent and basically becoming invincible and allowing stupid pressures like this to even happen, if someone figured out how to do this in a controlled manner that's asking for trouble

you shouldn't even be past 10 megapascals before you start breaking everything but the pressures and temperatures this is accumulating while broken is horribly bad

i guess you could put a tamper on people breaking this by putting a cap on what the circulators next to the generator or the generator can take before they break and need spare parts to repair at like 50000 kpa or something way above what the engine can reach under normal circumstances but way under what it can get up to in its broken state
