This is over 4x longer than the longest undersea cable in the world

HVDC transmission losses are quoted at 3.5% per 1,000 km

So 15.75% of the electricity would just vanish. That takes the shine off it a bit although if the price difference is big enough it would still be worth doing.

Well, even 84% sunshine transmitted is still rather shiny and is more than what is available at night.

And 1k km longer than the existing longest line
