Good point. A little hyperloop is nothing compared with CERN.
Cern beam tube is 6.3cm in diameter. And, you know, it didn't have trains zooming in it at 600m/s.

Elevated train platforms may have escape ladders, but I thought the Hyperloop tube was depressurized and the car within it needs to be pressurized. This poses a problem for the escaping passengers before they reach the ladder.
It's only a partial vacuum from what I understand. I'm not sure what kind of difference that makes but presumably it would be easier to depressurize in an emergency.

Aren't all real world "vacuums" really only partial vacuums?

Another thing, is that anyone that punches a hole big enough in the tube basically transforms half of the hyperloop into a bomb. Energy = pressure * volume. That's a lot of energy smashing through a hyperloop capsule. Basically, imagine if 3% of the tube was filled with pipe bombs, but in reverse.
Also, what happens if the pods leak? Seems like the air in the pods will diffuse through the tube and the people will suffocate.
ever been on a plane?

It's very irritating talking about whatever hyperloop is, because that the bar for what the hyperloop is keeps changing (Is it tunnels? Is it in a vacuum? If there's no vacuum isn't it just a tunnel? Is it your own car or a pod? There's solar panels somehow?). If we wanted better transport we should invest in busses and trains, which have better carrying capacity and better failure modes than whatever hyperloop is su…

If there's no vacuum isn't it just a tunnel? Is it your own car or a pod? There's solar panels somehow?). The Hyperloop concept is exclusively a pod in a vacuum tube. The electric cars in a tunnel concept is called the Loop (no Hyper), and it's a different idea e…
Thanks for clearing that up! I had no idea there were two versions of this concept.

The entire point of the Hyperloop is to get around right of way and politics. That is it's design. That is exactly what Elon is doing. You might argue it can't do what it's setting out to achieve, but this has never been a technological solution. He's designed a technology to fit with current societal processes rather than the old, get society to accept a technology.
Exactly this. That’s why The Boring Company is focusing on reducing the costs of tunneling dramatically. And they started by just using existing technology. With that (and without the cost inflation that many corrupted projects experience), they were able to achieve about $10 per mile of tunnel. A lane of highway per direction is $1m to $8m depending on if it’s rural or urban. They’ve developed a new machine, Prufroc…
Of course, if they can reduce the cost of digging, they’re also reducing the cost of the hyperloop’s biggest logical competitor; the subway.

>The problems with building this have nothing to do with technology but with right-of-way, investment, and politics. If those factors were solved, we'd already have high-speed rail in places where Hyperloop has been proposed. The fact that we don't says that Hyperloop is unlikely to be feasible as well. I disagree with your conclusion. Hyperloop technology is so lucrative that it might galvanize America to update its…
> "Cost isn't as much of a concern because a national hyperloop network would create a lot more value than a bullet train equivalent." What is the basis for such claim? Most of the information I come across points in the opposite direction. Trains are a lot cheaper infrastructure wise, and have ~10x higher capacity. Many public transport infrastructure professionals consider hyperloop a joke because it can only move…
Especially since HSR isn’t experimental anymore, it’s approaching a century old. America could just buy the exact same parts either France or Japan uses.

SpaceX and Starlink
You know and own everything about the other process so you can match them far better.
This is what Elon does. Hacks processes, not technology.
