Why do you keep bringing up AC-specific issues when I’m suggesting HVDC?
Also: since previous post Google says HVDC transformer/converter losses are about 1-3%, not 10%.

Could’ve put traditional AC cables on towers on the sides of any of the large selection of road bridges. They didn’t. Why?
(Likewise: as the waters are demonstrably spanned by bridges, they can be spanned by cable towers)
> so from you're original 50%, to 34%, a loss of 34/50, implying an increase in land covered of 50/34, or about 50% more land you have to cover.
In the context that one country can supply 6 times global demand an extra 50% (a hand-waving factor I expect to be excessive given most of the world is ocean and therefore not going to get so much wiggle) makes no real difference. It’s not going to be the limiting factor.

Same point. Land area isn’t the limiting factor.
