The head of High Speed Rail {of course} writes this off as Jetson's science fiction
No. Those of us who are engineers call bullshit on this. Evacuated tube transport pops up every generation. Somebody does some tinkering and then they start doing the math for construction and it all falls apart. This time is no different. There is a fundamental problem with the real-life feasability and economics of this thing.
Also, Paul Lanagan is a tit who thinks anything less than HSR is a failure.....but that's aside from what a waste funding a study on Hyperloop is.
but let us make that decision on facts and not on opinions from people who have vested interests {whether supportive or opposed} or fear of the unknown..
You don't need an engineering degree to know how economically unfeasible this is. It's a maglev in a vaccuum tube. Do you routinely invest significant sums of money in unproven technology that has not come close to meeting promised performance? This thing is not even close to meeting promised specs. Can't even go as fast as a Maglev yet. Let alone getting a safety rating that would allow passengers onboard. The space shuttle is more mature and safer than this at the moment.
Assuming they can even develop the tech (and everyone with half a technical brain is deeply skeptical on this), getting that safety rating would take years. Best case scenario is they put in as much effort as a space program (exactly what it would take to make this thing technically feasible and safe) and come halfway to their goals with a human rating in maybe a decade and a half. Are you willing to put off any investment in rail for that long? ...and that's the best case scenario where they start spending an order of magnitude more than they are today.....
I'd have less of a beef with this if Hyperloop hasn't almost universally become an excuse for governments to simply avoid rail investment by arguing that there's something new around the corner. And if there weren't so many fools who fall for that pitch.
Having lived in California, it makes my blood boil that this was taken seriously (and really only by those outside the mainstream technical community). Musk put this forward as a way to kill CalHSR which would have genuinely threatened some Tesla sales, as the whole project moved to enable substantial use of public transit in California (CalHSR was also substantially investing in suburban rail in SF and LA). And now, it's giving governments around the world an excuse to underinvest and put off necessary rail investment.
Here's a more realistic take for Kool-Aid drinkers like yourself:

Educate yourself.
Also, ask yourself this: Musk has invested in every one of his own ideas. Except one. Why do you think he hasn't invested much of his time or cash in Hyperloop?
