      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.

        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.

        Wait a sec, is the universe just God’s space heater?

      Indeed we’ve plugged in a bitcoin miner to our central heating and now heating is “free”. I’m not sure how profitable it is when you’re not using the heat though.
