Is it bullshit?
There is no redeeming feature of Hyperloop. Small things can possibly be fixed; the cost problems, the locations of the stations, and the passenger comfort issues given cost constraints can’t. Industry insiders with ties to other speculative proposals meant to replace conventional rail, such as maglev, are in fact skeptical of Hyperloop’s promises of perfect safety.
It’s possible to discover something new, but people who do almost always realize the context of the discovery. If Musk really found a way to build viaducts for $5 million per kilometer, this is a huge thing for civil engineering in general and he should announce this in the most general context of urban transportation, rather than the niche of intercity transportation. If Musk has experiments showing that it’s possible to have sharper turns or faster deceleration than claimed by Transrapid, then he’s made a major discovery in aviation and should announce it as such. That he thinks it just applies to his project suggests he doesn’t really have any real improvement.
IMO a far better and less exotic alternative to high speed rail or hyperloop for mid-range, intercity travel of a few hundred miles or less as an alternative to planes would be computer controlled cars and buses operating on existing roads.
I liked Alon Levy's coverage of it: http://pedestrianobservations.wordp...oopy-ideas-are-fine-if-youre-an-entrepreneur/
Some choice passages:
Setting hyperloop aside, high speed rail isn't exotic. It's a technology that's been deployed since the 1960s and gradually upgraded in the decades since. In comparison, self-driving cars are still an experimental technology that haven't been deployed in revenue use anywhere yet.
The problem with HSR is that it is expensive and requires tracks most of which don't exist in the US meaning it would cost a lot of money and political wrangling to create - so we will not have it anytime soon. Computerized driving uses existing roads and modified existing vehicles at far lower cost. For modest distances, what really maters is consistent relatively modest average speed. The Acela can go 150 mph when the tracks are good and theoretically could make the trip to NYC in less than 2 hours. In fact, it takes 3.5 hours and the high speed capability of the Acela is largely wasted by inadequate tracks, platforms and other factors. If a bus could average 90 MPH it would reach NYC from Boston in 2 hours. All I am saying is less exotic and costly technologies much of which are already in existence could make a huge impact on higher speed transportation. Hyperloop (not a new idea) and even HSR make great stories but given the cost and political situation in the US they just divert attention from more realistic and plausible alternatives.

It's 220 miles from Boston to NYC so even 90 MPH under ideal conditions doesn't cut it in under 2 hours.
And this ignores the terrible state of highway infrastructure. Interstate highways are not built to the standards required to have heavy buses traversing them at 90+ MPH in the quantities required to match railroad capacity. Maintenance-of-way costs would soar through the roof. Trucks already beat them up quite badly at 65 MPH. And that's ignoring the fundamental congestion limitations of highways, mentioned by F-line.
Of course, this is just another example of how the general public thinks roads are "free" and provided by the asphalt fairy, and that they last "forever" and never need to be fixed, other than pothole filling.
Self-driving cars/buses will, after a long period of maturation, have a great deal of impact on the way we make short trips. But why would you ride a 90 MPH self-driving, dinky little bus on a bumpy, degrading highway when you could ride a 220 MPH self-driving, comfortable train between the same destinations? Oh, and the technology to do the latter already exists. And we know very well how to maintain high speed rail tracks safely and still come out with an operating profit.
