ok. i am just pulling this idea out of my ass, but i figured i'd write it down.
so you have a peltier junction. stick in electricity, one side you get hot, one side you get cold.
now say you put a whole bunch of these in series. hot to cold.
now shrink them down and put a WHOLE bunch more in series.
you end up with a cord that'll transmit heat from a source to a destination. maybe make the cord long enough to dip in some coolant that is safetly away from your electrics. or maybe run some sort of heat engine with it!
