> There can be absorption points along the track Sure, but these have to hold a vacuum. No one has figured out a way to do that.
Gas pipelines hold hundreds of bar of pressure; I don't see how one atmosphere is a problem.

My instinct tells me negative comments aren't actually coming from the direction of "stupid idea! can't be done!". This isn't to say there aren't significant engineering roadblocks to the Hyperloop, but I don't think that's the root of the negativity. People are pointing out the glaring flaws in the Hyperloop idea, not because they can't or won't believe that crazy ideas are possible, but in reaction to the media's r…
He operates the first-ever successful private spaceflight company. (You can quibble with this but it's something close to the truth). Likening him to Barnum is a little insulting.
Likening him to Barnum would perhaps paint him as a little more nefarious than Musk actually is, but I wouldn't consider that insulting. The man was a master promoter. But perhaps he's not a good analogue because their "products" are very different. People liken Musk to Edison, and they did both own technology companies that produced innovations, but that's where the similarity ends.

My favorite is Dropbox. "Store all my personal and/or corporate files on some third-party server?! DOA."

Does it? If you used WebDAV then you can mount a share in Windows or Linux even over the Internet, and windows at least is good at caching it while you're offline for short periods. For someone who has their own always-on Apache it seems like this would replicate most of the use cases for Dropbox. I think the point that's being missed is simply that most people would rather see a few ads or pay a small fee than administer their own Apache, not that what Dropbox offers is technically so far ahead.

Branson's missing a d from his almost nominatively-determining name — the guy's got a talent for self publicity over challenging the incumbency, which for the most part he hasn't since launching Virgin Airlines and Megastores, which were both back in the 80s.
"Branson's missing a d from his almost nominatively-determining name" Wat? Edit: This has been a fun puzzle. I read the Wikipedia article for "Nominative determinism" and I've been swapping the letter "d" into various positions of his first and last name trying to figure it out. No luck yet!
The viability of Hyperloop One should not be the focus in the context of this article. That's not what this is about at all. It's that Hyperloop One needed Richard Branson on board because Elon Musk is creating his own competitor now. This is an incredibly smart move to ensure the survivability of the business from a publicity perspective. Branson has a history of doing things that people thought impossible or just a…

So what HAS he done then, other than brand anything he can then offload to third and fourth parties to run the businesses for him?
And don't say Virgin Galactic - that's just some clever peripheral branding to encourage the likes of the downvoters here that he is in any way novel or dynamic.
He's marketing clever, not strategically or developmentally-so.
I feel that name has got to be a double entendre.

To be fair, if Elon worked in the project for 40 - 80 hours a week, he probably could get a team to accomplish it at 1/8th the cost or lower. Consider he did this with rockets, getting them to under 1/10th the cost
He hasn’t done that with rockets. He wants to eventually, but he hasn’t yet. Let’s not let hype cloud facts.
Comparisons with non-domestic rockets are complicated by state subsidies and differentials in labor costs. But the Falcon 9 is approaching the 10X mark even before reusability has been priced in. Both the Falcon Heavy (in a few months) and the (eventual) reusable pricing should overshoot the 10X mark substantially.

I also was confused, but they probably mean “ Brand son”

Not ones that will hold a vacuum.
I am not an engineer. Is it impossible to create one? If a tube is a vacuum, then the tube moves, I don't think that negates the vacuum or does expansion and contraction make a vacuum impossible? I wouldn't believe so.

I’m just guessing on numbers, but that probably describes <1% of the population. Most people think Apache is a word used only to describe helicopters.
