So in my story the protagonist is a genetically enhanced vigilante that uses a full bulletproof jumpsuit in her activities.
But because of her accelerated metabolism, dealing with the heat of getting inside a closed suit would be undoable without a cooling suit, and i envisioned some sort of smart fabric full-body compression sleeve with embedded structural batteries that collect energy both from the movement and the heat of the body, effectively absorbing the heat and cooling her down even if it's a closed system.
The energy collected could be used for heating when it gets cold or drying in case of getting wet.
Does this concept make sense?
Edit: I guess i didn't made exactly clear what "closed system" means in the question, i meant that is an impermeable jumpsuit so there's not much ventilation, i though about it being coated in some futuristic waterproof coating like aerogel of some kind that would also fireproof the suit and provide electric insulation, but I don't think that the air would circulate anyway.
"jdunlop" made a good job of summarizing the question:
"can I cool an environment by capturing the heat as electrical energy?" to which the answer is "no"
If not by convection, it can still be by conduction and/or irradiation I suppose, and there are some very interesting suggestions in this answers, thank you.
Like the suit that conducts heat away from the skin, that would probably create a pocket of hot air between the sleeve and the jumpsuit, and I don't know if this is a good or a bad thing...
But there's also the irradiating coating option that could be applied to the jumpsuit, but i would rather it to have infrared camouflage and i think this would be more of a deterrence...
Maybe the jumpsuit could have some exhaust openings, in an angle where rain wouldn't enter anyway, how did i not though about this before?
