"Then it seems we could cut down air traffic considerably. NYC to Atalanta is only about 800 miles, if I could get there by train in four hours, a airplane would offer no time advantage.
If the difference in fuel efficiency is considerable, then maybe the US should consider building something like that?"
That is an interesting question, that I will have to go research.
I need to try to find credible numbers on the relative total-system energy required of hauling people via each method, and for hauling a ton of freight via each method.
I even wonder what the total cost of each system, say over 20yrs, would be.
