Some of the more culture related comments:

There is a belief within American media that a successful person can succeed at anything... The people who are already doing the same thing are peons and their opinions are to be discounted, since they are biased and he never is. He doesn’t need to provide references or evidence – even supposedly scientific science fiction falls into this trope, in which the hero gets ideas from his gut, is always right, and never needs to do experiments.

Pretty much a line-by-line breakdown of Hyperloop. Thanks for finding that.

Why San Francisco - Los Angeles, and not the Las Vegas - Los Angeles loop? Because Vegas is more playground than business destination, and the two metropolitan areas are so much bigger than metropolitan Las Vegas. If you're going to dream big and create a future transportation option, there is little interest in making it a novelty in the desert. SF - LA has so much more potential, and the existing Interstate provides a likely path with limited eminent domain issues to overcome.

There's nothing wrong with wanting to do something between LA and SF. I just think this is getting a lot of undue attention. Personally, I' wouldn't be surprised at all if this is a little joke a billionaire is having over us.

Either that or he's been watching too many Star Trek movies. More likely the hype around the hyperloop is his way of developing positive buzz around the Tesla brand name, thus boosting its stock price and attracting investors. Musk said he has no intentions of ever building the hyperloop himself. In other words, its vaporware.

That is not what he said...He in fact suggested he could get a proto working in four or five years.

He said it was not something he was willing to take on at this time...primarily as he was already overloaded.

His attack on HSR has lots of merit. Too costly, too slow. So there has to be a better alternative.

I suspect he is correct. So we need a better stalking horse.

I liked the analysis of the g forces and such in the above response. That is the stuff that leads to truth.

On the other hand you can triple his numbers and you would still have a winner compared to HSR.

Nonsense. HSR is a real and proven technology. In terms of the number of people that can be moved per mile HSR is more cost effective than building more highways. His claims that it would cost less than HSR and even less than highway construction is laughable at best. Musk makes a lot of bold claims, but has yet to build even a single mile of test track or tunnels to back it up. Do you comprehend the difference between fantasy and reality? The promoters of the hyperloop don't seem to have a very firm grip on the latter. They are constantly speaking of it as if it were a real proven technology, when in reality it is nothing more than a figment of their overactive Trekkie geek imaginations. It's embarrassing to watch.

Ohh Really...you watch the price move around? Which CA HSR are you referring to as a reference?

Really? Which CA HSR are you referring to? And how do you account for the rental car at the other end?

Yes I admit I too am skeptical. But perhaps you could cite the CA experience with HSR that leads to your view?

Gee I would like to join you at the CA HSR site where reality can be seen and touched. And where we see the economics on HSR really work.

His claim is that it costs to much...which appears to be the case in the CA line...and is too slow. You argue that it is in fact HSR is economically cheaper than many alternatives...but you say nothing about too slow. I commuted back and forth between LA and SF or SJ more than once a week for 15 years. I have not heard any reason why I would give up the airplane so far...So who is it that is going to populate this HSR?

You obviously have no clue what HSR is or how it works. Look it up on Google and get back to me.

True of so many of you. Challenged you run behind the shed and hide.

Does that not embarrass you at least a little?

In Europe it's often quite a bit cheaper to fly than it is to take their HSR. I'm not sure if it would end up the same here in the US, but based on prices of the existing trains here, I wouldn't be surprised.

I'd like to think that this idea is feasible, but at this point it's hard to tell. I'm sure a lot of people thought the idea of boarding a tube in LA and arriving in NYC only 5 hours a later was impossible, but yet here we are...

...100 years and hundreds of billions spent later.

By that line, yes, Hyperloop is technically feasible, though the context faced by Hyperloop in 2013 is different from aircraft travel in, say, 1940. Different comfort and safety standards and wildly different costs. So, the incrementalism of the airline industry may not be possible for Hyperloop, which would have to start at the bar that the airline industry spent a century to reach.
