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. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

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](h (social.graves.cl)

Yes it does. There's no such thing as an inefficient electric heater. I'm the US they sell 2 kinds. 750w and 1500w. The differences between them are all a matter of form factor. Maybe a nice fan to circulate might be what you like though.

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.
