Yet we don't do that today, either. Do we? Also, water is not as easy to handle as electricity, and such a system seems to be more complex than a sandwich of computing layers and thermoelectric cooling layers. Additionally, the side where the heat finally comes out of the package, could be connected to a thermoelectric generator, thus converting some of that heat back to electricity, which could then be used to reduce the total amount of electrical input, thus raising the efficiency of the entire system.
