Refrigeration cycle scoffs at your mere 100% efficiency
Refrigeration just moves heat, it does not create it.
Why create heat when you can just steal it from somewhere else, though
“Waste heat” is a relative term.
Why drink my milkshake when I can drink yours? I can DRINK IT UP!
It would end up creating some due to inefficiencies, which would contribute to the heat at the end.
Not true, it is true that it is heating at %100 efficiency that is to say %100 of the electrical energy is being transferred into heat (although technically some is being transferred into IR light not necessarily what you want) but your goal is probably not to simply create heat your goal is probably to heat the room or at least yourself and their is plenty of waste heat going off into space somewhere also you can achieve more than %100 heat transfer by compressing the external air’s heat we call these heat pumps and they can achieve +400%. The key word is efficiency.
It’s always wild to me that 100% heating efficiency is actually kinda not great. Also the fact that we can use the heat from air that is colder than what we want in order to generate more heat I mean that’s just witchcraft.
Well, we’re not generating heat with heat pumps. We’re compressing atoms to make them angrier and pass other atoms by that bunch to even out the angriness. Could also substitute the word jiggy for angry.
I get that(enough, anyway, I just need to watch some videos on them to be honest) but it’s still super wild to say out loud.
Which part, getting jiggy wit it or the witchcraft?
I always like to muse that in terms of electronics the heat is caused by resistance to current and that heat is usually considered inefficiency, and since no other load exist or work is done that means heating elements are about -100% efficient.

ir light is heat dawg
Well, heat pumps are significantly more efficient than traditional heaters because they move heat rather than generating it. A heat pump can deliver three to four times more heat energy than the electrical energy it consumes, making them 300-400% efficient.
Boo, get heat pump you loser
Most of the time, we consider heat output to be inefficient. It only works here because heat happens to be its purpose.
You could say it’s 0% efficient.
I dunno, I’m seeing some light.
Light is absorbed by materials and ultimately becomes heat.
and what happens to the energy of said photons once they interact with your retina?
(As a nerd) I came here for the nerdy comments.
People say efficient without saying efficient at doing what with what.
Turn that entropy up to 11, boi!
That is how the power supply of my Laptop look like, playing Cyberpunk 2077 on my laptop.

Winter is gaming season.
I was testing the AI image generating capabilities of a M1 MacBook Air 16GB.
It shuts down at 113°C (235°Freedom)
113ºC is hard on the limit, chips at 140ºC convert the PC in an Paperweight. Normally they desconnect the Device with >90-95º. Permit 113º is maybe related to an programmed obsolence policy from Apple.
So hot.
You’re objectively wrong here.

Pfftt. Splitting wood is peak heat thermodynamics. And I can attest it keeps you warm down to -40F.
