To my understanding, many processes require cooling to achieve optimum use.
Power stations, for example, require cooling for electricity production.
Computer hardware systems, similarly require cooling for the CPU.
My question is why don't these systems make use of the excess heat energy, for example, to power more turbines/cpus, in a sort of 'distributed workload'.
The idea being that the heat energy should naturally dissipate across the space.
I realize that this would likely decrease the speed/efficiency of the main working unit, but wonder, would it not be compensated for by the output from /many/ units?
This is mostly a theoretical question, and I'm also just wondering if anyone has already been working on this problem and where to find the research.
