Please point out the differences. Please do!

I got told time and again that Ds and Rs are so vastly different, but in the end what was eventually touted as the huge dividing topics was petty, insignificant bullshit that may actually affect people on a personal level like abortion or gay marriage, but that has neither any impact on 99% of the population nor on their economic situation, their chances or their prospects.

Technically you can scale Hyperloop to several times higher speeds, if you can build sufficiently straight segments (e.g. Great Plains). It does however require one alteration of note: you have to increase your leak compensation pumping capacity severalfold (it's an unknown at this point how bad leaks will be, though they tried to be pessimistic in their assumptions), while injecting hydrogen or helium to maintain the same pressure. Ideally hydrogen (it's not explosive nor embrittling at such tiny pressures, although its behavior when compressed would need to be studied). You need light gases to raise the speed of sound inside the tube (also reduces air resistance / compressor mass throughput requirements). Water would work also instead of hydrogen or helium (it's a gas at those pressures), although not as well (but better than air).

At least, pessimistically it's required. I don't think they've done anything to simulate what sort of temperature the rarified gas inside the tube would maintain under full load (the effect of passing vehicles on the tube itself is trivial - the gas is a terrible conductor of heat, and the tube has a huge convecting surface area). If the rarified gas was left significantly hotter than the tube (due to its poor conduction of heat), that too would raise its speed of sound.

Have you ever been able to trust it? I doubt it, so nothing has really changed in this regard and the timing of this question seems partisan.

Oh, fucking please... Have you ever heard such juvenile falsehoods uttered by official Whitehouse representatives before? Unless you're Kellyanne Conway, you have to admit that this is different. The good news is, if they don't get this silly bullshit under control, they're going to drag the entire GOP down with them.

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.
