> The "whole country" is irrelevant. You can't transmit arbitrary amounts of power across the large geographic areas, most of energy has to be generated in a reasonably close proximity.

Only technically correct because you said "arbitrary": it's well within China's manufacturing capabilities to make a grid that can transmit 3 TW over 40,000 km, with a conductor cross section so thick it only has 1 Ω resistance.

As in: all the world's current electricity demand, the long way around the planet.

I have, in fact, done the maths on this.

> Transmission lines are expensive, regardless of your ideology.

"Expensive" but not "prohibitively expensive".

All infra is "expensive". Nations have a lot of money.

And it'll turn out to cost more than building a nuke in each backyard.

No.
