Same solution Japan uses for high speed rail. You're in a tunnel. Now you're out and instantly on a bridge! Now you're off and instantly in a tunnel! Now a bridge! Tunnel! Bridge! Tunnel! Bridge! (repeat until you arrive at your destination)

That said, tunnel costs are proportional to diameter and bridge costs proportional to peak loading, so a Hyperloop-style system wouldn't be such a bad idea in such an environment.

A more detailed breakdown of the differences versus high speed rail in general is in this post.

As for versus maglev: maglev is even more expensive to construct than conventional high speed rail, and suffers from the same design challenges that Hyperloop is designed to eliminate. Beyond that, Hyperloop is entirely self-powering - it uses so little power (coasting the vast majority of the time) that it's easy to have enough solar panels atop the tube to provide for its energy needs. Anything not in a rarified atmosphere moving at those sorts of speeds is plowing against a large amount of air resistance.

The small size of Hyperloop cars is a feature, not a bug; it's not just the cross section that's kept down, but the length as well. By keeping cars small (but frequently launched for equivalent throughput), they minimize peak loadings. Viaduct costs are roughly proportional to peak loadings. Elevation allows them to reduce a huge amount of overhead costs (the majority of the costs of a typical rail project) and eliminates a lot of the technical challenges with HSR involving ground shifting and earthquakes, transferring all of your support to readily adjustable fixed points.

As for passenger comfort, the interior looks more comfortable than any train I've ever been on. Of course, you can't get up and walk around, but then again, trips are so short there's not really any need to. I would say that the excellent leg room would be great for stretching out for napping, but that would be a very short nap ;)

As for loading, multiple capsules are loaded up at once. It's not a one-at-a-time thing.

What is so difficult for you about reading the design document, "dumbass"? Did you really think that that isn't covered? Section "Earthquakes and Expansion Joints". The tube is not firmly affixed to each pylon; it's mounted on a multiaxis damper. Its positioning is automatically controlled relative to independent factors, including earthquakes, ground shifting over time, and daily thermal expansion (which results in planned for anticipated changes in bend radii as well as a net overall expansion or contraction at the endpoints)

What it is about some topics that convince people to go online and write rants without having read the design document? It's not that long, for crying out loud. It's one thing to disagree with a particular engineering decision. It's an entirely different thing to have no clue what the engineering decisions are but still rant anyway.

Why the fuck do you expect change now?

I don't get it. I really don't. NOTHING changed from one administration change to the next for the past decades. Oh yes, there was a war on terror. Oh. And? That would have been in what way different under any other rule?

Face it, folks: You're fucked. You have a system in place that allows you to choose every 4 years whether you want to feed one group of useless gits or the other group of useless gits. That makes a huge difference for the gits, and that's why that election fight is fought tooth and nail because it's all or nothing for them. Fo you, it's nothing. Either way.

Mostly because you don't get to choose who you can vote for. That's chosen for you. In the end, when you strip the whole fluff, the whole spectacle has a lot of the old Soviet times when you even sometimes got to choose between two candidates from the same party, supporting the same ideals and the same economic system, not questioning in the slightest the all-holy doctrines and differing in insignificant bullshit topics that were hyped and emotionalized to insane levels despite having exactly zero impact on anything that really mattered in the end.

Let's be brutally honest: The same is true for your DemRep Party.

Comment Re:Use that low pressure air (Score 1) 88

Inductrac is less efficient than air bearings and the track is more complicated to build than straight pipe. That said, if the air bearing concept proved unworkable, I'd think it a fine fallback alternative.

The costs of the turbomachinery on the current design is factored into the budgeting. And you need it either way unless you're planning to run a hard vacuum, since otherwise the vehicle will compress the column of air ahead of it. Industrial air compressors aren't exactly new technology, although the operating environment is admittedly a bit unusual ;) But I do have to agree with their choice of focusing on air bearings. They're simple, light, equal or greater efficiency in comparison to magnetic, and most importantly they keep the "track" simple. The main downside is that they require a fairly high wall smoothness (hence Hyperloop Alpha's need for a rotary tube polisher).

Sorry, not gonna work. Yes, that used to work out back when the American dream could still come true, but know what? It's over. Been over for a long time now.

The American Dream was "work hard, climb the ladder, make wise investments and one day you'll live comfortably".

Doesn't work anymore. You can work your ass off and you will won't get anywhere, earn enough to actually make any investments and you'll never live comfortably. You'll work to your grave.

The new American Dream is "fuck this, try winning the lottery or get hit by someone with money with his car and sue his pants off".

Comment Re:Terrorist target? (Score 1) 88

If you're going to detonate bombs large enough to take out a concrete column for a big steel pipe, why wouldn't you do it where you'd kill a lot more people rather than "hopefully lucking into causing enough deflection (by increasing the span) right before the next capsule arrives that it can't decelerate sufficiently in time to handle said deflection, and possibly killing or injuring one capsule's worth of people"?

Airplane attacks were popular because of the ability to kill hundreds of people at once, or to hijack planes and use them as weapons. Not exactly applicable to Hyperloop. And even airplane attacks seem to be falling out of popularity, in favour of coordinated shootings and plowing through crowds.
