Its nearly impossible to create a perfect vaccum. There is still some air, and moving at 750 mph that "some air" quickly rises to regular atmopheric pressure unless you equalize both sides of the capsule. Hence big ass compressor, although its not really a compressor in the traditional sense.

>Subways aren't profitable
Because they're poorly designed because Americans have a problem with mass transportation for some reason.
>Rail itself is barely profitable
Once again, because it's a shit design. Why would you wanna go on a train when your own car would get you there faster, even with heavy traffic?
>High speed rail isn't at all
Because America doesn't have any shithead. Like seriously how can you expect something America doesn't have to be profitable when there's no one there to use it? Here in california, people are just completely against the idea of a high speed rail for some reason. My own father has said that "People hate it because trash from one city will travel to another city easily and no city wants the bad people from other cities". Again, people hate that other people can move without cars because americans are so enslaved by their vehicles.

I legitimately don't understand why America is so backward when it comes to mass transit systems. Europe does a marvelous job at connecting people from one place to the other. Hell, you can travel from the UK to any place in europe and it's a god damn island!
Yet, in a giant landmass like the US, we can't travel 40 miles without some train derailing, or going into a traffic jam, or having bus systems that are so slow that it would be much better to walk where you need to go.

Maybe a hyperloop might be exciting and innovative enough that people will finally see its benefits.

Maybe people will be stupid and continue being stupid. But who cares? At least those with an actual education and an actual purpose in life will be part of this pioneering movement. And when years pass and we all die, people who didn't believe in it and didn't do it will be forgotten, while people who worked to progress humanity will live on in history.

you can have many cars if you want, the limit is how close together can they be
lets use the extremely conservative number of 1 car every 2 miles, the us is 2800 miles across
thats 1400 cars running between both coasts of the us (theres one tube that goes and one that comes)

each car would be as cheap as a truck, lets be conservative, about 80.000U$S(eight thousand), against a passenger jet plane which is at least 250.000.000U$S (250 million, or 250 thousands of thousands)

so for each car you buy youre saving about 312500% the money!!!

oh and bad news for you little kiddy non sciency boy

there is almost not mantainance costs to this system, its lesss than a train. all is magnetic maglev non mecanic, all is absolutely 100% wear and tearless

so its a just one time only investement and after that your economy will increase by 312500% times each of the 1400 cars = 437500000%!!!!!!!!!!!!!!!!!!!!!!!!!!!

Nobody flies freight you dumb fuck, and if they do it's done rarely, 99 times out of 100 it's moved by train and trucks, so do a fair comparison and compare it to freight trains. Also:

This project will never work.
1) moving massive amounts of freight with steel wheel and steel rail is the most efficient means known to man.
2) the sheer amount of work building the tunneling , not to mention the time it would take, go look up the Goddard tunnel project.
3) the electrical requirements for this project would staggering difficult as the entire line has to be wired to the same power source (Electrical engineers know what I refer to)
4) Where the hell you going to get this much copper?
5) I would rather spend the money and get a high speed rail network built, sadly the airline companies are suing as its 'unfair competition' and winning ( see Texas high speed rail)
6) No idea how you think a single railway car carrying a single container can possibly be remotely as efficient as a double stack train on steel rail.
7) the important one, what the hell do we need to ship from LA to NY this damn fast? takes 80 hours for a container from LA to go to chitown. and how many weeks by a boat before it got here from China? the time saved shipping when it reaches America is not that relevant
8) freight railroads in America make massive profits and are considered blue chip investments
9) why not build a rail line over the Bering strait and connect Asia to Alaska, or a trans Atlantic rail tunnel for the same money?
10) Remember the L5 retards? same concept
11) any one with a basic engineering degree can debunk this whole thing as a really dumb concept.

Looks like they went to the design competition. Also looks like they didn't run with my tandem compressor idea.

Last I saw them here was right after New Years. Not too surprised they've stopped coming here; they caught a lot of shit from /sci/ in that thread when posters realized it was basically an ITU senior design team looking for help from /sci/ and "representing" us without formally declaring their relationship with us (almost like a homework thread, heh). Plus, the design weekend itself (when their design proposal was supposed to be finished already) was at the end of January, so yeah. Judging from the paucity of updates after January, I suspect they lost and didn't make it to the prototype stage (which is really to be expected from a design that apparently wasn't even close to finalized a mere month before competition).

What's the plan, to loop around the world three times?
Because while giant vacuum tubes are surely expensive, if you're making thousands of kilometres of it you're going to have to get a factory to do the work, though that so happens to make it cheaper per metre.

You're not going to need much in the way of pumping air out if your tubes are rather airtight, and if you get a factory to just spew out steel tubes with rails in them then that sounds pretty damn airtight and not too pricey either.

The train succeeded for three reasons 1) it blew it's only real competitor (the canals) out of the water (no pun intended). 2) At the time there was a big upsurge in goods needing to be transported due to the industrial revolution and 3) It was actually using existing infrastructure, railways existed long before locomotives did, they were horse drawn. it was just a case of changing the rails from wooden to iron. Hyperloop is not any faster or has any more capacity than a plane, it needs completely new infrastructure and there is no pressing demand for it. it would have to be way cheaper for it to be worth it and plane travel is already pretty damn cheap.

In short I think it's a great idea but there's no market for it. Musk should save it for Mars, as he said himself you don't even need the tube up there and it would be actually necessary seeing as plane travel in the Martian atmosphere is infeasible.

I have another issue with the hyperloop, it is not very pleasurable. A large part of why Europeans love trains so much is because there is a whole culture of scenery and relaxation around them. Americans are more practical and serious so never really understood why Euros preferred to sit in a train watching the cows go by instead of sitting in a car looking at tarmac. Hyperloop doesn't even have the scenery angle, it's not fun at all. You are in a windowless tube. However it's not a huge issue because my own country is famous for having underground railways in tube shaped tunnels and they are hugely popular.

It might be beside the point, but it's hardly pointless, all the time the US still imports the majority of it's products.

The reason I bring it up is: there's little point in discussing at length the stupidity of a new transport system on basis that it won't account for 1/10 of the goods transported on land today. It's a red herring in a world increasingly reliant on sea transport.

250 km/h is when travelling intercity. Transcontinental railway only works in a place like USA, and would be closer to 500-600 km/h.

not to mention the fact that airports are decentralized for the same reasons railways are not. If you take an ICE train in Europe, you can go from commercial centre to commercial centre in a matter of 1-2 hours. If you try doing the same via air, you spend 1-2 hours simply going to and from the airport, waiting for the eternal bottleneck to clear, going through security...

we're barely scratching acceptable range for personal vehicles, and those aren't supposed to haul 40 tons of cargo across thousands of miles nonstop

Only to a degree. Time becomes worth a lot less when you have to pay a lot more for the privilege.

well we did consider the tandem, then came up with a simpler (and way cheaper) solution that doesn't use axial compressors - basically a gas dynamics expert joined us and offered a rotational compressor system which checked out.

>"representing" us without formally declaring their relationship with us
the team started off 100% from /sci/, then that team imploded because aerodynamics design went nowhere with no aero engineer, so we had to patch up with students from ITU. it's a shame though, the initial team could have done wonders, like the Reddit team. The ITU students were mostly inexperienced, although they worked hard.
I've told from the beginning that after securing the sponsor and passing the design stage, I would start working a 4chan vs Reddit narrative, which would allow us to regroup a larger team on 4chan that would operate along with ITU without fucking up team identities. That didn't work because the following:

>I suspect they lost and didn't make it to the prototype stage (which is really to be expected from a design that apparently wasn't even close to finalized a mere month before competition).
True, and I'll give you that the design completion was a hectic process. Although we prepared our strategy based on a SpaceX rule that teams with sponsors autoadvance, and we were one of the few teams with a sponsor. However SpaceX changed the rules on the last week and introduced elimination, so our design flaws became way more decisive unfortunately.
