Forget that. We should build a high-speed train to Japan. It can go under or over the ocean, and the governor of California can head up the project, as he has valuable experience with these things.
The initial stage should begin 200 miles off the CA coast and end 200 miles from the Japanese coast.
Derailment or breakdowns would be bad halfway across the Pacific.
Moonbeam would only have one track and train. Solar powered of course.
