New York to London in an hour - by train
Good luck holding a vacuum under the ocean. I read stuff like this and I think, "Gee, I don't think these people have actually built anything." because if they had they would realize that if it costs $1M a foot too build subways [1] in cities with moderately skilled labor, its going to cost $10 - 25M/ft to build something like this. That's half a quadrillion dollars (448 trillion dollars). What sort or rate of return do you think you would need to make that feasible?I'd love someone to actually do a credible cost analysis of an evacuated tunnel train. Unfortunately I don't think Oster did.[1] http://secondavenuesagas.com/2010/01/14/the-costs-of-second-...
