Not really? The best heaters are heat pumps which can under typical operation reach 300-500% efficiency (COP). Technically they aren't converting the electricity into heat, but for arguments sake here about heaters we only care about electricity consumed to heat generated.
One could argue that it is 100% as every Watt that enters through the socket (not counting reactive energy) is going to become heat at some point in the very near future, including the air moved by fans, the photons emitted by the screen, etc etc.
The determination to pull through a project of this scale is mind blowing and the joy is contagious.
For me it's the skill. So many things you have to be good at to build this. Really impressive and slightly jealous.
@3:10 “you need to consider 99.9% of the power is converted to heat” uhm that would be quite an efficient heater you designed there!
Isn't that lower than a purely resistive heater?
Only if the resistive heater in question is DC or AC with reactive power compensation
A purely resistive heater, by definition, has no reactive component so there's no reactive power considerer.
The 0.1% mentioned might be the light that the project produces.
? that is just any computer
