A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

The more air conditioners in an area the hotter becomes around it. In turn increasing the demand for AC. Infinite money glitch. (lemmy.world)

They're more than 100% efficient (they move more watts of heat than they produce), but they're less than ∞% efficient (they use Watts of energy still, so they still produce Watts of heat)

100% efficient would mean they do their job without any waste heat. They create waste heat, therefore they are not 100% efficient.

The only thing that is 100% efficient is an electric heater, because its job is to create heat, so it doesn’t create “waste heat”.

A heat pump can heat a home by more than the energy in the electricity it uses. It's more than 100% efficient at "converting electricity into heat in your home". It does that by not actually covering electricity but by moving heat, and it is less than 100% efficient at converting electricity into motion, and introduces some waste heat

The efficiency of a machine isn’t measured at how effective its job is, but how efficiently it does that job. If it moved heat without producing any waste heat, it would be 100% efficient. If it produces any waste heat at all it’s not 100% efficient. No machine can ever be more than 100% efficient. That would violate the laws of thermodynamics.

Hence why I clarified what it was efficient at doing.
