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? @showerthoughts@lemmy.world

But a YouTube ad told me that "a college kid blessed with a gift for engineering invented a heater that uses 90% less energy" and that I should order one now!

God, I hate the existence of those ads. I hope people are smart enough to not get scammed by them, but their continued prevalence suggests otherwise.

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.
