> Who is Japan interconnecting with, or any other country that doesn't trust its neighbors? What is Canada supposed to do when it's ~6000 km from the equator and might not want to rely on the US for electricity regardless?

With space. By space-based solar power instead of HVDC.

I would really love to see your per kwh costs estimates. It currently costs about ~$2,700 to launch 1 kg of mass into orbit.

Your link has 100 to 500$ per kg to LEO for Starship as target.

How much is one mile of HVDC?

Err, and where? Chinese HVDC? Canadian? US? Yurop?

Think of all the needed metal and area vs. a few fields of 'rectennas' to reinject the beamed down microwaves as energy into the already existing grid?
