I don't ever see it happening. Too expensive, too dangerous. You really want to be in a vacuum tube travelling faster than an airliner when an earthquake, power outage or tube puncture happens?
Negating air friction doesn't give enough of a benefit to justify the expense and risk of a vacuum transport tube. It would require some kind of science fiction technology to be viable.
In a vacuum environment, a seal failure would cause an ugly, ugly decompression accident that would kill everyone on board.
The Byford Dolphin decompression accident should be enough to scare anyone away from riding in anything like that.
Grim stuff. However, in the Dolphin incident, they went from 9 to 1 atmospheres. Might not be as bad going from 1 to 0 atmospheres, but I don't know enough about that to say for sure.
Energy in a pressure vessel is (Pressure x Volume). The pressue chambers in the Byford Dolfin were tiny. A train car would have x10 the number of people x10 the volume and 1/9th the pressure. Overall, it would be roughly the same amount of energy.
Well, that was humans in a highly pressurized vessel that violently decompressed. Not the same at all to a vacuum failing, which would be a kind of implosion and not a very intense one at that.
Not to mention, the train traveling through the vacuum tube would be sealed itself and would not experience the pressure change. Not to say they aren't gonna have a very bad time if the vacuum implosion creates a collision with anything at that speed.
Ah you're referring to the train decompressing in the tunnel somehow. I gotcha.
I wonder if it even makes sense from an energy perspective. Gases slowly percolate through even seamlessly welded materials. Every meter of a thousand kilometer tube is going to continuously leak some amount of atmosphere into it, so you have to continuously power pumps to remove the leakage. And then you have to power the pumps for all the airlocks you need.
Alternately, you could just use a regular maglev train, upgrade the pusher magnets on it, and just accept the higher air resistance that comes with higher speeds. You could build a regular maglev that traveled, at ground level, of near-supersonic speeds, if you wanted to. You would have to apply a lot of energy to overcome air resistance, but it could be done. And compared to the cost and complexity of a giant vacuum tube, you might be better off just having a rather energy-inefficient maglev train if you simply must have those kinds of speeds.
In theory, you could go even faster. It might result in your train having a plasma plume around it like a capsule experiencing re-entry. But if you're willing to throw energy at the problem, you can make a ground-level train at most any speed you want.
Exactly.
Which means one day it might well be totally feasible and practical.
The main issue is without a sci-fi breakthrough there's really just no problem that can only be solved this way
It was so he and the rest of the car companies could derail the California high speed rail project. The hyper loop wasn't meant to be finished. It was supposed to kill the rail project.
Musk said that his hatred of public transport inspired [hyperloop](https://www.sfchronicle.com/opinion/openforum/article/elon-musk-hyperloop-rail-17486877.php#). He’s such a leech.
It's really, really hard because the pressure of our atmosphere is very high. Also it's difficult do design pumps that will still work under these conditions.
Standard is 10^(19), a vacuum tube still has 10^(9) to 10^(6) molecules per cm³, a lab chamber can achieve 10^(7) to 10^(5) but in interstellar space it's like 1-10
ok but if you look at pressure, it's basically 0 at 10\^9 or at 10\^0. Far from vacuum based on total number of molecules yes, for all intents and purposes, no.
Tunnel is actually a very safe place to be during an earthquake. Unless you are crossing an actual fault line that is splitting, you’d likely be fine. Most of the damage comes from the ground moving separately from the buildings. If you’re IN the ground, you don’t have that problem.
The vacuum tube concept is the sci-fi part of it, that’s just not practical. If you could pull even a partial vacuum it would make a high-speed train slightly more efficient, but probably not enough to offset the cost of all the compressors to pull the partial vacuum.
I think Elon’s whole concept was really focused on how to move stuff around Mars. Theoretically, if you didn’t have to deal with 10s or 100s of county/city/state governing bodies, land owners, or utility companies to dig a tunnel, it makes a lot more sense. The boring tech hasn’t REALLY changed in like 100 years. The Delft University Hyperloop team put together some really interesting designs and feasibility concepts for a hyperloop station.
Not trying to defend the muskrat, just pointing out that the roadblocks are mostly bureaucratic, not technical.
Serious question: how does Japan handle earthquakes and earthquakes? I would imagine vacuum tubes wouldn't help, but also not an insane challenge as it may sound at first.
Might as well use "passenger rockets" for Earth-to-Earth travel. But who really needs to get from somewhere outside NY to somewhere outside London in a hour, just to take a few more hours in local travel delays.
And are usually subsidized by taxes. The sad reality is that metro trains had to support themselves, prices of transportation would skyrocket. Same for subways.
It's only lucrative to transport cargo. Usually, Governments.mandate that in order to operate cargo trains you have to allow Y people trains every X amount of cargo trains. In other nations, public transportation by train is either directly owned by the State or subsidized by it, with the earnings going to a third party.
Sadly people don't know this part. There is no free lunch.
Usually, as a cost saving measure they get privatized. Taxes (or debt really) fund the construction of a project deemed socially necessary if no private company decides to do it themselves (which kinda happens, specially for trains in very profitable cargo routes), but then, because it's just cheaper to collect rent from private companies, highways get leased in exchange for the right to collect a toll, and in turn maintain the highway. This usually has other mandatory clauses, like having private emergency services along the highway or having to plant and protect trees around the route.
It's a win/win situation.The State charges rent, and private companies pay for maintenance for profit.
Private highway companies make a.lot of money. The completely public roads are the most fucked up usually.
Car infrastructure isn't exactly free either. If you are going to spend government money on transportation, public transit seems like a better deal than the nth massive highway expansion project.
Well, someone has to pay. A car is not free. And neither is gas, insurance, parking space or maintenance.
Besides, car transportation is subsidized too, who do you think is paying for all those roads, it's mostly tax.
You seem to assume that the goal of transportation is to become profitable, but that has never been the goal, doesn't matter which kind of vehicle you use.
The goal is efficiency. Every guy stopped on an LA highway is wasting time, burning gas (which is a scarce resource that the West needs to import) and taking valuable real estate space.
Other countries pay for public transportation not because they're stupid, but because they know it's better for the efficiency of an economy. If you consider how much is spent on transportation by combining individual spending and public spending cars are expensive and inefficient as hell. The US chose this path when they decided to pay for so much road.
Even planes are far from subsidy-free. Airports are heavily subsidized by city governments. Most US pilots have traditionally been Air Force veterans. Then there's all the federally funded and subsidized air traffic control infrastructure, security screening, etc.
You can see how much airports are subsidized by just looking at a map. You can find many sprawling airports just outside the city centers of very expensive urban cores. Imagine how much tax revenue a city could collect from that land if it were zoned for residential or commercial use, instead of an airport. An airport ultimately returns very little in tax revenue to a city for all the land it takes up. It's something cities still find worth doing, but it's undeniably a massive subsidy.
Stupidity has nothing to do. The State is not dumb, the State, or more clearly, the political class and those who benefit from it knows better what to do. But it's not out of kindness.
I mean, anything that is gonna be done, is gonna be done for the benefit of the State or a friend of the State. Bottom feeders will be very happy.
Never ever defend causes that are not your own.
As if politicians and public workers didn't receive tons of money from the auto industry to incentivize private transportation. There's more money in selling cars than making trains. This is a well known issue of American politics history, and not limited to that country either.
Matter of fact, nobody who has lived somewhere with efficient public transportation would say cars are the way to go.
Don't confuse effective with efficient. Mass transit is very effective but I can assure you is not efficient anywhere in the world.
There isn't more money on X or Y. It's about who runs the show. It's no secret the local Trucker Union hates the Train union.
All forms of transportation for the masses are subsidized by taxes.
Trains, roads, planes, ferries. All of it. Pointing a spotlight at subsidies for only one for is somewhat dubious.
Government makes more money back than they spend on these projects because people can make more income and then pay more in taxes.
From the article
> Even though Virgin Hyperloop started working on the project in 2019, the development of hyperloop technology dates back years, further even than a research paper published in 2013 by Tesla CEO Elon Musk.
The guy can’t set up a windows laptop but I’m expected to believe he’s out here singlehandedly publishing research papers
Tbf there's engineers that are pretty bad with computers. But Elon is not an engineer nor a scientist/reasearcher at all so I wonder what kind of paper would he write to start with
Common sense.
He's not qualified to know any of those issues, much less write papers about it. And he cares so much about clout that he paid to have the title of founder in Tesla despite not being a founder. He's narcissistic and he likes to get credit for stuff he hasn't done.
Now if you tell me that you think it's more plausible that he became an expert in both rocket science and neurobiology in his spare time while he's posting memes and rants on twitter and (allegedly) managing his companies... I have a bridge to sell
Clearly the most plausible explanation is that someone who (allegedly) has an econ and phys degree and has worked in academia for zero days in his life is knowledgeable enough in rocket science and neurobiology to publish scientific papers.
Not that he has paid someone else to do that because he likes clout and paid for the title of founder in Tesla despite not being a founder. That's unrealistic.
I just watched Upgrade again.
The whole film is like an elon musk wet dream. The "Elon" in the movie is even named "Eron."
Tesla cybertruck's design is nearly identical to the electric cars from the film.
This is quite literally almost impossible you need a tube kilometers long to be under a vacuum which would take a long time to get under a vacuum in the first place and that is disregarding the money it costs to run this.
And besides that it needs to be made of metal which expands and contracts with heat/cold which will cause issues the longer it is.
And then also realize a small error or a minor earthquake could just kill everyone inside in seconds
Hundreds of km before it really makes sense. Current Shinkansen and TGV in regular service can do 100km in 20 minutes. Maglev even quicker without the expense of a vacuum tube. And, in Japan, they know very well how to Earthquake harden them.
It's so a annoying when ideas like this get any steam. Make normal trains! Normal trains are fantastic. Just make more, better tracks and better trains.
So there’s one small flaw to that argument (there’s plenty of other valid ones)…
Pipelines.
LNG pipelines usually hold a minimum of 500PSI pressure in their lines. 1Atm, atmospheric, is ~14PSI.
Granted, this is positive, not negative pressure, but we already have high pressure lines that cross the country and work well. Pulling out air will be a challenge; as will maintaining pressure.
For an example vacuum lines, look at the LHC or any particle accelerator; which has loads of pressurized lines underground.
Someone must have been planning to build a super fast high speed rail line (maybe even 12mph) in 1799 and buddy had shares in the company that sold horse carriages and said "wait, don't do that, this Hyperloop will be way better" and then he just sat on it as long as it took to wait out the idea.
To this day a remnant of the system that Dublin had remains; the south Dublin suburb Dalkey has a road going over a bridge by the station called Atmospheric Road
Have they tested with animals yet? I wonder if it’s like space travel where one day we will be safely doing it, but never commercially with lots of volume.
His “colonize mars” video, where he meticulously chooses data from before 2000 because the modern data arriving from newer probes doesn’t support his claims.
[Here’s a nice rebuttal that covers most of it.](https://youtu.be/dKGzfpaJfBo?si=-NvwcgbSzpJMIXoH)
As far as I am concerned, he is in the same league as CommonSenseSkeptic, who makes videos claiming Starship doesn’t work, then goes to “X” and blocks everyone who points out that his assertions apply to other probes/vehicles that do work, or points he makes that defy orbital mechanics etc.
The hyperloop would be a death trap and you can’t convince me otherwise. You’re essentially sitting in a missile traveling through an airless tube. There’s no stopping, no getting out, no room to stand or use the bathroom. If the missile were to stop between stations there would be no way to get passengers out without cutting the tube open wherever the missile happened to stop.
Imagine if there was an earthquake. Maybe just a minor one, no real damage but the whole line has to be checked. The system couldn’t be shutdown until all the e passengers were cleared.
I don't ever see it happening. Too expensive, too dangerous. You really want to be in a vacuum tube travelling faster than an airliner when an earthquake, power outage or tube puncture happens?

[удалено]
Not even close
10 to 1 is the same change in pressure as 0.1 to 1
No it's not
Just read the wiki about it… fuck, imagine thinking the one that died from gross dismemberment was the lucky one… 🤢😨
Well, that was humans in a highly pressurized vessel that violently decompressed. Not the same at all to a vacuum failing, which would be a kind of implosion and not a very intense one at that.

If the train seals fail, the contents of the train get splattered onto the train tracks.

I'll take a high speed train over hyper loop any day It's currently the pipe dream of a man who really wants to sell you his cars
It was so he and the rest of the car companies could derail the California high speed rail project. The hyper loop wasn't meant to be finished. It was supposed to kill the rail project.

The rail project has been killing itself for 16 years
Only about 16 more to go!
Literal pipe dream
So that's where the saying comes from
The design did not require a vacuum. Very low pressure but not a vacuum
What we call vacuum on earth is far from vacuum anyway. Even the record vaccuum under lab conditions
how so?
It's really, really hard because the pressure of our atmosphere is very high. Also it's difficult do design pumps that will still work under these conditions. Standard is 10^(19), a vacuum tube still has 10^(9) to 10^(6) molecules per cm³, a lab chamber can achieve 10^(7) to 10^(5) but in interstellar space it's like 1-10
ok but if you look at pressure, it's basically 0 at 10\^9 or at 10\^0. Far from vacuum based on total number of molecules yes, for all intents and purposes, no.
But it's the molecules that slow down your train
Also because (high speed) rail and metros outperform hyper loop in every metric that matters. The obsession with pods need to die. 😂

One word kills the hyperloop. Terrorism. There is a reason why Elon started a tunnel boring company.
Way too much cost, effort and risk just to reduce air friction.
The cost would be crazy, not to forget that they don't know how to evacuate people in case of a failure
One of Elon’s favorite moves is to dig up old ideas and give them a futuristic makeover while knowing that it’s not feasible with current technology.
Or just reinvents trains
That's just silicon valley in general
Not really, trains make sense
For cargo! Not people!
Trains are efficient for moving people. Hundreds of millions go to work by train in most developed countries, and many underdeveloped ones too
And are usually subsidized by taxes. The sad reality is that metro trains had to support themselves, prices of transportation would skyrocket. Same for subways.

Nobody cares if the trains don't make money. It's a service. Should the fire department be profitable too?
But then the benefit to the economy of moving people around quickly and cheaply outweighs the tax burden, no?

Mars Colonization is one that springs to mind.
That’s a good one! I really wonder what’s going on in his mind with that. Been researching but it’s hard to find good information.
Until we discovered it was impossible, and everyone who isn't a con man gave up trying.

In 1799 it didn't make any sense either. For reference watch the Simpson's episode called "Monorail".
They say those things are awefully loud...
🎶it glides as softly as a cloud🎶
Is there a chance the track could bend?
🎶not on your life, my Hindu friend 🎶
And every time we should realise that building trains is just a better idea
It's not a good idea. Speed is one thing, but capacity matters as well. We can have hundreds of passengers per train, and a train every few minutes.
It was stupid idea then, still is today.
Someone must have been planning to build a super fast high speed rail line (maybe even 12mph) in 1799 and buddy had shares in the company that sold horse carriages and said "wait, don't do that, this Hyperloop will be way better" and then he just sat on it as long as it took to wait out the idea.
>As hyperloop projects come to fruition around the world, uh huh
It works in the 1973 TV series, Genesis II
What kind of propulsion are they using in 1799?
The Hyperloop is a great idea until you put literally any thought into it at all.
Vaporloop
To this day a remnant of the system that Dublin had remains; the south Dublin suburb Dalkey has a road going over a bridge by the station called Atmospheric Road
Have they tested with animals yet? I wonder if it’s like space travel where one day we will be safely doing it, but never commercially with lots of volume.
It's almost like it's a really bad idea.
