It could be, but it's unlikely to be. People in Germany and Japan are quite opposed. In the US, it doesn't make economic sense. Not going to make it to 85% of the western world without those countries on board, even if you don't consider Japan to be in the west.
Regardless of the merits, people don't want these generators near them, and there's not a lot of site options that are close to transmission lines and other important needs, but not close to people.
This is the magic climate change solution. You're yada-yada'ing over the part that is going to be all but impossible.
