    Oh, that’s interesting. Peltiers have been stuck where they are for over a century. Every once in a while, some tech tuber will try to use one on a CPU and finds that the power requirement is too high to be useful. Rinse and repeat with another tech tuber every year or so.

    Why, no, technology doesn’t magically get better just because time passes. It gets better because someone did the research. And sometimes, it’s just as good as it’s ever going to get.

    Nice to hear about an improvement in this one. Not sure if it’s good enough to replace compressors, but it’ll be useful regardless.

      Improved thermoelectrics would also be useful in reverse for harvesting otherwise wasted heat energy from anywhere hot and cold surfaces intersect. Instead of replacing active cooling on a CPU, use passive cooling and use the Peltier/Seebeck/Thomson effect to harvest some of the heat into power. Of course, the most effective use would probably be on engines and other devices that get much hotter than CPUs.
