Actually I was quoting my dad... an engineer who designs power grids for a living.
Yes I have an uncle who did that for around fifty years but I do not pretend to speak for him, I'm speaking for myself with only a few years experience in the electricity industry and a couple of decades elsewhere - but really we are discussing this at high school level anyway so you should be able to stand on your own two feet here.
Pretending HVDC is some magic bullet
I did not do that. I suggested you consider what the losses actually are. Perhaps you should read the subject heading since you appear to have missed it. I put it there in an attempt to make it more clear that I was not suggesting some not yet existing perfect magic bullet like your superconductor strawman.
It was also extremely offensive when you got this portion of mountain out of the tiny molehill "if you discovered some kind of power generator that produced enough power for the whole world at near-zero cost, but it only worked in one place (yeah, I'm not even going to guess what that might be)"
WTF is it with that attack? All I did is mention something that has less losses than the average coder thinks are in electricity transmission. Why build your mountain out of that molehill?
