> Say what now? Are you trapped in the 1950s or something No. Reality. Where in the US do we have a power transmission line that goes significantly farther than 300 miles? Also, if I had to guess, I would not be surprised if the super high voltages required to go farther are so dangerous to people, wildlife and the environment that they will never be build in the US or Europe. China doesn’t care about such things.

> they will never be build in the US or Europe. Here's a map of HVDC projects in Europe, some of which have been about since the 1930s [1]. Canada has several long distance HVDC lines (eg: [2] "recorded on the list of IEEE Milestones in electrical engineering") while the US to date mainly uses HVDC to interconnect existing AC grids (eg: [3]) although there are significant proposals for long distance HVDC to share renewable energy.

Can you back this up with reference to the past 50 years of HVDC in Europe and demostrate DANGER!! at levels significant over AC transmission?

  I'll repeat the question: Where in the US do we have a power transmission line that goes significantly farther than 300 miles?

    What is this dumb argument you're trying to make here? That if no long distance HVDC transmission line exists in the US, then they cannot ever be built, even if the technology has been demonstrated in many other countries? I'll point out this argument would also rule out Gen IV reactors and breeders, which we also don't have in the US. Without breeders, the world economy cannot go nuclear, so I guess you're all on board with renewables now?

    In today's list of things that are apparently incomprehensible, demand can be shifted by more than the length of one transmission line. Consider three cities and four generators with a 300km transmission line between each. g1--C1--g2--C2--g3--C3--g4 Each generator normally sends 1GW into each transmission line, but today g1 produces twice as much amd g4 produces nothing. g1 powers C1, g2 powers C2 and g3 powers C3. The electricity must have teleported 1800km, it's the only explanation. Otherwise you'd have to consider an idea like some kind of 'network' of 'transmission' and that you need to model an entire system with nuance rather than pretending each element is completely isolated and has a constant load with no variation. Similarly energy can go through more than one interchange. Electrons don't have a little ttl counter, it just reduces efficiency some.
