The warp core was originally a space babble replacement for a boiler on a steam ship, since it was based on WW2 navy ships. On old steam ships literally almost everything ran directly on auxiliary steam. As a result of probably not revisiting this since the 60s: everything in trek runs directly on warp core plasma.
Does the bechdel test take the job of the characters into account? For example if Dr Crusher is talking to Dr Selar about a patient's health does the patient's sex alone decide if the talk passes?
