clearing bits far away from computation

[Bear]

I'm still not seeing the advantage.

Scenario A: Do your computing. It generates waste heat. Transduce the heat into a cool rock and eject a warm rock. (or, you know, radiator fluid or whatever)

Scenario B: Exactly the same, except with technobabble and reduced efficiency.

Seriously, how is dispersing the entropy of computation, by converting it into heat and using a thermally conductive medium, more effective than dispersing the entropy of computation, directly as heat using a thermally conductive medium?
