    A brushless motor only converts ~5% of its input to heat. That’s low enough that you can reasonably call it a side effect.

    Now, a computer, that’s a heater that happens to produce math as a side effect. 100% of its input ends up as heat.

      I love firing up my PC and gaming on cold winter nights. A well placed fan or two and I can spread it through my entire apartment and the heat won’t kick on all night. Ends up saving me money, my heater costs way more than my PC to run.

            By “well below” do you mean -30? Or do you mean -5? Either way, you must have much better insulation than I do, because I have multi-kilowatt heaters and even on not-so-cold days my poor PC can’t compete, no matter how hard I game.

              Like anywhere from -15 to -4 C (around 5-25 F). I also keep it around 15 C (60 F) in my apartment to keep heating costs lower so it doesn’t need to get super warm to keep my thermostat from kicking on.

      It all becomes heat eventually in the end though. Sometimes it’s just a multi step complex process outside the physical bounds of the heater.

      Is the universe just God’s space heater?
