If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? @[email protected]

I mean if you want to go that route, we could just say that every speaker, light source, motor, etc is 100% efficient at generating heat because all of its energy output will eventually become heat.
That is also completely true, but meaningless because heat generation is not the purpose of these devices. However, if you use them in a building heated by a thermostat-controlled electric heater, you’re effectivhly running them for free.
I‘m was using two old servers with folding@home running as space heaters in the winter. I got them for dirt cheap and thought if I convert electricity into heat, I might as well do something good with it. Also nice opportunity to run a minecraft server for the kids during that time.

You double-posted this comment, FYI
One for each server.
It’s still efficient because both those comments will end up as heat anyway.
Energy can neither be created nor destroyed so in the grand scheme of things, everything is 100% energy efficient one way or another.
I suggest we submit proposals to define “100%” and “efficient” before we design the experiment
