She'll be fine, she was put into hibernation mode or some such, she's just "in" the pod since the alternative is shoving her in a closet or something, it's just storage for lack of a better term.
I'm more curious to know why KK's place doesn't have its own nuclear energy production or something, considering the very Tony Stark-esque setup she's got going with the secret lab and all. I'm also curious to find out if Artemis has been uploaded with every fighting style known to man, assassination techniques, terminator-like strength, and if the intruder (Daniels I think?) is going to survive his encounter since he seems to be trapped in there with her when the place went into lockdown and she's up and about now.
