Interesting but doubt we'll see it awhile as it also sounds super expensive.
Ok, well maybe in China. The interesting thing is maglev technology has been around a long time but buying up property in a straight line is just so bloody expensive. There it's not a problem, they just kick you out, so that's why they have a maglev.

I'm thinking they could use some of the train tracks that cross the country.

No because train tracks do turns. I sincerely doubt that anything capable of 4000 mph can do anything not perfectly straight or a curve over a great distance- as I've said, maglevs for example go about 260 mph (at least that's what I think the Shanghai one does) and they can't go on old train tracks for this reason.

Well its pretty easy for a physicist to work out the minimum radius.
They say no more than 1G of force. At 4000mph its not much of a turn before that gets hit.

Yeah but actually calculating that out requires effort.

What I find more interesting is that they intend to create a vacuum in the entire length.
That'll be the biggest vacuum chamber on Earth to date.

Will you stop pointing out issues with design and cut them a check for investment already?!

If I could write a check that big I'd be a far happier person.
