exactly! finally someone among the dreadfully negative comments that gets the process! How does everyone else in this section thinks roller coasters are tested?
The hypeloop will be absolutely fast, safe, cheap, comfortable, and environmental friendly. Not to mention it will generate more energy than it needs. On top of that it's easy to build, that's why Elon Musk is letting students build it. "It's not that hard." Why does that sound like a scam? 🤣
Think of the ISS, they generate oxygen in space as required for months/years on end. The same could easily be done in a pod. We are a long way from people getting in, they'll experiment with cargo for years.
yeah cause you don't need to breathe right? The shuttles will carry enough oxygen for normal operation just by volume, but there will likely be a backup in case of a holdup. what that backup is is still unclear, but it could be a pressure bottle with oxygen for example. ps if you say something stupid like "get educated" help people do so then.
Two questions: 1) How long does it take to pump down a 100 mile tube? It must take weeks. That's a lot of disruption if vacuum is lost, and they have to pump it back down. 2) Imagine you're half way there and the car breaks down. How long till you run out of air? Suppose a car's seal breaks, how long till you die from vacuum exposure (probably 10 seconds?).
Loving the comments about how dangerous and impossible Hyperloop is :) I wonder if these people have ever traveled in one of those flying, pressurized, winged tubes at 38,000ft in the sky? At 600mph. With up to 36,000 gallons of jet fuel stuffed into the wings and under the cabin. What about a metal box with wheels that travels up to 70mph with nothing but a cage, nylon straps and bags full of air to protect you? Oh, and you have to operate it. And also, there are thousands of other people operating them all around you at all times. And some of them suck at it. And you really worried about a vacuum leak? THAT'S the thing that scares you? What exactly do you think would happen if it depressurized? What is it EXACTLY you are so afraid of?
it will shoot you out of the tube like a giant rail gun traveling at the speed of sound? theres nothing to hit in the sky, existing transportation working is not an excuse to put yourself in obvious danger.
Going from horse and cart to combustion engines is a lot different than going down a giant railgun at the speed of sound. Under that logic, I could shoot myself out of a canon because `airplanes are too slow` with zero regard for safety. Combustion engines became popular, but did you ever hear about the forms of transportation that failed? Look up selection bias, you've excluded all the situations where transportation ideas haven't worked out. Example: Bennie Railplane (a monorail which was powered by a propeller). I get that innovation is important, but the hyperloop is a perfect example of "good in theory, bad in practice". Example: How is a 350+ mile long tube going to deal with thermal expansion? Cars driving into the support pillars causing vibration/damage? What happens in the event there is a loss of vacuum? It would be more practical to build a giant high speed railway like in Japan which is just a track.
Well sir, do you think engineers haven't thought all of these things you are afraid of? I'm sure they are working on security measures for pressure loss, for thermal expansion, vibrations etc. With that i mean, give them a try. Don't judge the project without knowing.
(Near)vacuum is nothing near air pressure at 30 000 feet. Ever seen explosive decompression victims? Look it up. Besides, it's not as dangerous as it isn't economically feasible. Build a 600 mile long vacuum tube with operating costs lower than an airplane and only then brag about it.
I'm not stupid enough to not read my own comments for obvious mistakes before posting. You obviously understand English well enough. I know it was an easy-to-make mistake - That was kind of my point. I'm also not stupid enough to enter an argument about a different language than my native one with a native speaker and expect to win. It's good to know you don't take Thunderf00t seriously. In my opinion he's not even worth watching as a joke. He's a tiresome bore. I don't really like the Hyperloop concept, though. I think it's a bit whimsical in it's impracticality and a waste of resources.
There's nothing wrong with what he did to scare away the popularity of the hyperloop. Other than like, pretending to be an authority when he isn't, and potentially hindering technological progress by misinforming the public.
I though the hyperloop tube concept was actually not in a vacuum state ? But Low pressure, with pods designs with fans in from of it to create event lower pressure/vacuum at the pod location ? Am I mistaking myself here ?
Lord Lima Bean That remains to be seen. No company has demonstrated a full system yet, let alone operation and maintenance. The Space Shuttle was a great idea on paper, too - fully reusable, cheap and safe access to space. Reality turned out to be less ideal. Maglev trains are a known concepts, there are data points for actual installation, operation and maintenance costs. No such thing can be said for Hyperloop, so I remain sceptical.
It's green... until you factor in the energy it needs AND its construction resources. Seriously, just build normal mag rails, it is way better for the environment, and it is actually practical to build on mass, as opposed to trying to build a vacuum system hundreds of times larger than the worlds largest vacuum.
Expecting a test traveling video but got another bla..bla...bla... Expensive to build, expensive to maintain. Doubt it ideal for public transportation.
they are like cheaper, faster, safer, self-contained (power-wise) maglev trains, they are definitely not for everything, but they will have their uses.
Matthew Jenkinson True, but the difference is, that back then there were no known alternatives. Today we have bullet trains, maglev trains, subsonic aircraft as well as cars. Each of these modes of transportation is well developed, well understood and the pros and cons are known. Hyperloop on the other hand seems to try to fill a niche that arguably doesn't even exist and implementers make bold claims while having nothing to show for it. Also note that all of the above only refers to Hyperloop as a concept. The first commercial aircraft had the advantage of actually existing and being in operation. To date, Hyperloop is nothing but a concept, a few sub-scale models and technology demonstrators. We've yet to see a test installation, e.g. one that demonstrates the system (including tube, capsule and airlocks), and companies keep telling tall tales about environmental friendliness, low costs and high comfort...
totalermist you realise that Hyperloop is essentially a Maglev train inside a tube, right? With all the massive costs already associated with Maglev trains - but by introducing a vacuum they increase the efficiency of running it. This is the same concept behind a BEV - initial construction is more expensive, but long term costs are much cheaper. I have yet to see whether it balances out vs a Maglev, but I can see how you might construct the track and run the vacuum pumps for less than the amount you save on energy for propulsion. And it would be able to negate air travel and it's associated emissions on certain routes - would only make sense on high throughput routes, for example. The trick is you have to compare the construction cost ($ and pollution) versus running an alternative - how much fuel cost is there running jets over a high traffic route for 30-40 years, I wonder? Not to mention engine maintenance, and all the other assorted costs and emissions. We could probably assume the actual carriages would be similar to a similarly constructed aircraft.
What they're trying to prove is that by introducing a vacuum to Maglev, you can run the train at speeds exceeding that done by aircraft, at a running cost better than normal Maglev. Cross country trips that save you time and money, why wouldn't you like it? Sure, has to be proven, but it's worth at least finding out rather than just poopoo-ing the idea based on nothing but theory...
Earthquakes are the least of concerns facing this project, besides the fact that it is a vacuum which is extremely dangerous they have yet to even address thermal expansion.
Aaron ray Both are very interesting problems. Good thing they are setting up these test tracks in the hot desert close to California so they can tell us what happens.
Matthew Jenkinson I don't think it will create copy its not time travel, in time travel there might be chance of creating copy but in teleportation case there you just have to invent mechanism to convert physical form into transportable form n again into physical so we are not dealing with time
That's exactly what I mean. With teleport, you don't transfer matter, you transfer information. The 'from' pad will read your matter, turn it into a data stream, send it to the destination where you will be re-created. If you don't also destroy the original, then there will be two of you. Of course, we may do it using some form of bending of space as with a wormhole - nobody really knows yet.
Matthew Jenkinson this systems will just work like pipe which will transport matter from 1 place to another, if water will be transported form 1 place to 2 then how there will water agin at place 1
The biggest problem I see is that we will only have another form of travel that has to have tsa to go through because of a holes in the world. I hope this can work and want it to work, but I also share many of the concerns that others have like earthquakes, air pump system sufficient enough for ridiculously large volumes. Even. If they did away with the vacuum, it would. Still be advantageous in The tube for lower air resistance. I don’t know what the air. Dynamics would do though with pod shape and tube reactions though. Couldn’t you have a. Breezeway of sorts for the hyperloop where you have the pressurizing section so then you wouldn’t have to re-pressurize the whole system?
Don't you see that the claim by Elon Musk that a ticket will be dirt cheap (less than a bus fare for the same distance) and your comment about people having to open their wallets is a total contradiction? The simple truth is that we know a lot about magnetically levitated trains, we know a lot about pipelines and other big and long tubes, and we can make all the hyperloops we want, except for the fact that it is not economically feasible and it is not acceptably safe for human transportation. Elon Musk's drive towards making this monumentally expensive endeavor in a dirt cheap configuration takes you to stupid engineering designs, like the lack of expansion joints and the lack of a concrete inner cylinder that would impede the implosion of the tube in case of an accident. This is a textbook case of bad engineering, where you solve the minimum possible number of challenges to get something that works under ideal conditions, ignoring the much larger issues of safe and effective solutions.
Doesn't the same thing go for trains and 1 lunatic with a big rock to derail them? Sure, trains have been derailed by lunatics, but nearly not enough to stop using them, or even be a valid threat to that mode of transportation.
The thing is when trains are derailed, only that particular train and that portion of track are affected which can be corrected in reasonable amount of time. Here in H'loop, if a dent forms somehow all the outside air is gonna rush in at supersonic speed and will crush the entire tube, right from the point of impact to the very end.
I don't think you're right about the tube being crushed. As far as my physics knowledge goes, air flowing into the tube decreases the pressure, so there would be less chance of a collapse compared to even its original state. Again, that's maybe my limited knowledge of physics. I do think you've got a good point when talking about a dent. I wonder if the system would notice a dent when there is no pressure loss. An unnoticed dent would be disastrous for any vehicle hitting it at large speed.
Thermal expansion is a real problem for a normal railway track, here you have a tube which makes it very very complex problem to solve. Making it even worse is that every movement (and eventual expansion joints) must be handled without leaks... Commercial 2021? That is without any doubt vapour hype, empty words for investors...
I think the best solution to solve this problem is to put the hyperloop underground.There you have the same temperature all time long. And secondary you don't have to struggle with different ground levels
I don't see anything about this project in the engineering press - makes me extremely suspicious that they don't yet have any solutions to these big engineering problems.
Amazingly there are no major engineering problems with creating a vacuum. Building a air tight train is simple, and the speed is guaranteed. Everyone keeps making up fake "problems" that do not exist. So many fake engineers making thoughtless posts.
the speed of sound is inversely proportional to the density of the medium in which the sound travels - the less air the lower the speed ... will certainly be faster than the speed of sound in the pipe ...
There's a very simple answer to that... No. Well... If you pull the cost estimates straight out of your arse then hyperloop is viable. If you don't it isn't.
How many of them do 1200 kmph? If it can't do 1200 kmph then they need to build it so it can. Wait, they can't build one that fast? Why not? Air friction you say? If there was only a way to remove that barrier...... I am thinking maybe a large tube, underground, with fast trains zipping by. Would not even have to build it through peoples houses, just go deep under them.... yea... that could work.
There were already projects for maglev trains in a vacum tube. They have been stoped because they were too expensive. Chinese companys actually bought this technology recently.
I wonder when the Hyperloop developers will start talking seriously about the pressures and speed they can actually get away with. Details provided at the start of the project were ambitious to put it politely. Also how does having very strong supports help keep things steady in the event of an earthquake? The system would need to be very flexible and the strength would not stop the wobbling. If the ground itself is moving things attached to the ground will also move. I really hope they can make it work but I have an engineering and science background and it just doesn't feel right. Simply put too much energy is required to reduce the pressure to the level needed for smooth movement. They could probably drop the pressure a bit. Sadly a bit would not be enough to make it worthwhile. It would require a lot of time and energy to drop the pressure 'a bit'. Anyone who wants the mathematical and physics argument against hyperloop could do worse than check out Thunderfoot's videos on the topic. Has anyone else noticed that Elon Musk has a hands-off approach with hyperloop yet a hands on approach with his boring company? Elon seems to prefer tunnels to tubes.
Chriswsm Chriswsm I have to say that your comment, unlike many others I have seen online regarding Hyperloop, is civilized. There are many educated people such as yourself, who have reasonable doubts, questions. Please, try to take into account that there are people more than qualified working on the project, people with an experience far greater than mine (I also have an engineering background) , yours or your average youtube pseudo intellectual commenter. As absurd as it may look, I'm pretty sure they'll figure it out EVENTUALLY, and as long as they do not share concrete updates, we shouldn't bother too much.
I think earthquke is the least of the problems. There are dosens techniques in use for building shock resistance buildings so it's nothing to study here, they can take an existing solution.
But all of the existing techniques, as the @Chriswsm pointed out, are resolved by becoming MORE flexible, not LESS as I think was alluded to in this video. Pylons would need some sort of independent suspension so that the loop stayed rigid while ground underneath was allowed to flex and move around.
An earthquake should be fine inside it, and the pressure isn't going to be a vacuum or anything crazy like that, just lower pressure, all energy for everything I believe on most versions of this is from solar panels, but you do make good points, I think the whole point of this is less about the thing itself, and more to get all these companies to learn to work together, or at least not be trying to kill eachother as hard, and that there are other ways than to be greedy and be the only one doing an idea.
"The biggest challenges now aren't technical" I suppose that's very true if you think ignoring the obvious and massive technical problems makes them go away. Earthquakes, terrorism, thermal expansion, the fact that if the tube ruptures everybody in the system dies and the infrastructure is destroyed, the fact that the touted economics of the thing are complete bullshit ... Here... Let me just wave my hand and everything will be fine. Let's be honest here... The idea of a 700mph mag-lev train in a vacuum tube is well within the ability of man if, and only if, you ignore the massive disadvantages of a vacuum tube over a more traditional open air version. The vacuum tube version is lower passenger density, higher energy consumption, costlier to build and many orders of magnitude more dangerous for the passengers all for the sake of saving half an hour in journey time. It's pretty much the same 'theory' as the push for supersonic air travel and look what happened to that.
Woah! You're right! Imagine what would happen if people would get into large and heavy metal tubes, side by side with tonnes of highly explosive liquids and expect them to lift off the ground... Also sounds pretty dangerous to me...
""higher energy consumption" rofl" Absolutely. The energy it would take to evacuate the tube and maintain the vacuum exceeds the saving on atmospheric drag. The energy cost of creating an almost total vacuum of 0.02 bar are astronomical and the energy needed to drive the proposed turbines on the vehicle (actually molecular pumps) is also astronomical. In fact the turbines will be hideously inefficient *because* they are running in a near perfect vacuum. For fuck's sake... Evacuate a pipe and then put a turbine powered vehicle in it? Seriously? What ever Musk was on when he thought that one up must be some pretty strong stuff.
"Woah! You're right! Imagine what would happen if people would get into large and heavy metal tubes, side by side with tonnes of highly explosive liquids and expect them to lift off the ground... Also sounds pretty dangerous to me..." Well in fact early aircraft were appallingly dangerous things to get in but when they crashed they didn't destroy the airfield and every other plane in the air. If I'm on a 747 and something goes wrong I'm in trouble but the 747 behind and the 747 behind that one and the 747 behind that are fine. If you want a more accurate example think of a subway system like The Tube in London. At peak times there can be a train going past any given spot every three or four minutes but if one train crashes, breaks down or becomes derailed the absolute worst that is possible is that the following train hits it. If it were comparable to the HYPErloop everybody on the same line dies no matter how far away from the original incident they are. You simply can't get round the fact that the vacuum in the tube is its Achilles Heel. Any breach of the vacuum would lead to the explosive recompression of the whole system destroying everything and everybody in it. And destroying the system itself in the process. The only way to avoid the danger of the vacuum is to not have it and then you're left with a normal train which is what we already have.
How to waste money. Step 1 ignore thermal expansion. Step 2 ignore the reality that travel time has been massively offset by mobile internet access. Step 3 get some famous guy to talk up this ball.
I think it's really unlikely that they have overlooked thermal expansion. That is engineering materials 101. Any somewhat competent engineering firm would recognize the importance and plan accordingly.
DVD playerz DVD playerz step 1: do you really think they're engineering something major like this and haven't thought of thermal expansion. Step 2: with that reasoning we should stop improving our transport system because we have the internet?? Step 3: this 'guy' who's talking it up is a successful businessman, inventor, engineer and intellectual. All things I'm sure you (or me} are not.
“the biggest problems aren't technical. It's bringing the people to open their hearts." That is by far the stupidest thing I heard in a video that centers around hyperloop. Technology and science aren't about believing or not. Hyperloop in it's current form with super long evacuated tubes is no viable solution for large distances. The problems with thermal expansion in combination with sealings, the safety of the passengers in scenarios of pressure loss, the costs, the amount of people that can be transported... The list goes on! Stop selling this as some kind of dream people need to believe in. Maybe the money can be used for much better causes at some point if the majority finally understands, that this thing will never be "the future of transportation" -.-
The point isn't large distances, the point is a bit shorter distances very very fast, and this isn't the only hyperloop project, there are 12+ companies working on the mode of transportation called "hyperloop" some of them, like this one, have hyperloop in their name, even tho they are not hyperloop.
That line irked me too, it seems like thermal expansion would be a huge problem, and that's assuming they can vacuum the air out of a miles-long tube in the first place.
Lima, what do you mean 12+ companies So far what I have seen from "hypeloop" is shitty rusted insides of the pipe, super slow pods that can barely accelerate on their own, phisical problems like thermal expasion and general safety when it comes to *near vacuum over long distances* . Also, the inside of the tubes need to be cleaned off from dist and other particles cause its fucking full of them. There is NO working prototype of something travelling REMOTLEY close to the speed of sound in the hypeloop by your 12+ non existant companies.
What happens if someone shoots a rifle at the tube? What happens if it fails, and you are stuck inside a passenger capsule? HOW exactly do the rescue teams get to you?
ok so obviously they are using different techniques to levitate the capsule. in an other video they were using air to levitate with a partial vacuum and now they are using magnetic levitation with complete vacuum. you can already tell which model is going to be faster. very interesting.
Earthquakes are a non issue. Ever been in an earthquake underground? No? Hint, it is a non-event. Earthquakes only affect the surface. You know, where your cheap home that was built sits. Did you take earthquakes into account before building your home? Is is earthquake proof? No? why not? That is dangerous. You could die.
Hyperloop on Mars? What for? To run between those two Martian colonies which don't exist? How about a first step of actually landing a man on Mars first before we worry about moving colonists between the two colonies which we've inexplicably built so far away from each other they need a train. Talk about putting the cart before the horse.
Anthony: I don't think I said anything here that you criticize. If and when Mars gets colonized, the equatorial area will be the warmest and sunniest region, on an otherwise frozen planet. Off planet passenger and freight will best be achieved by way of space elevator. Transport from the base terminal can be fast and easy with hyperloop, especially given the very low atmospheric pressure on Mars. Next time, check with me before you go off making foolish comments.
OK... So *IF* we colonise Mars, because living on a planet with a breathable atmosphere which we evolved over millions of years to live on will be so boring we'll all go to live on a barren rock with no atmosphere and no protection against ionising radiation. *IF* we do that then the hyperloop will be a great idea even though it's pointless as Mars has no significant atmosphere to cause drag... This is getting quite pathetic. You're using something that's currently not much better than science fiction to support a scheme that is clearly impractical and dangerous in the here and now. We've not put a man on Mars and there's no immediate chance of that even happening... And you're talking about how the colonist are going to get about? What next? The Martian Hyperloop will be fitted with phased plasma rifles in the forty watt range to defend against the Marauding Magenta Mars Mammoths?
ISMH on this... What if a accident happens and you have to get out of the car or tunnel? Not enough space to Walk out or away from say a fire... Like in subways you have walkways along the tracks to the stations to get out of the system and Air plus Safety people to get too you...
So we shouldn't advance because someone might die, maybe. If this is safer than other forms of transport (wouldn't be hard to beat car travel), then that's a good reason to do it.
true but you're saying that as if there haven't been crashes and horrible deaths caused by other modes of transportation. example: DRIVING... even planes crash once in a while. planes are statistically the safest way to travel but when they crash, you don't see people saying "im never going to fly on a plane ever again because of that one extremely rare crash"
yr, but it uses switch of current to distort magnetic fields to create current, in return generate heat on the track, this is the problem facing maglev trains, plus it is very expensive to cool
They also pretty clearly stated that earthquakes were taken into consideration. The people behind this aren't idiots, of course they know to be weary of shit like that.
They might have told you that there are no more significant technical problems, but that's definitely not true. I'm really curious if they are blind for the obvious problems or they ignore them for some reason.
Don't you have brains to think why? For too many reasons... Too expensive to build at a national level. Not profitable. Dangerous. This, like many other bs projects that are seemingly coming out nowadays, is very unrealistic at this point in time.
Ah! Okay, little smart man! You clearly know more than my father... You apparently know more than an engineer. Sorry... I didn't wanted to insult your intelligence with my dead weight mentality. Again! Please, forgive me!
Why not just make it so that there are 2 long tubes one way tubes. One for each direction. Then have feeder tubes branch off of the main tube? Like a subway system but with airlocks. Even if you need to have airlock doors at the junction points that would open only when needed between the main line and the branches.
Seems some of the biggest hurdles that are delaying these projects is strictly bureaucratic - permits and cooperation from all the different city, state and federal agencies are typically a quagmire.
That is what I thought when I first heard about it too, but after some more reading, it actually makes a lot of sense, it's basically just a cheaper maglev train that goes faster.
It's going to take A LOT of materials to build this between cities or even countries. It's very cool though and is without a doubt be a part of the future in one way or another.
They should be focused on THERMAL EXPANSION rather than the passenger experience. Or have they solved that? I'm a big fan of this concept but it seems like the hardcore engineering challenges of creating a 600 km (San Fran-LA connection) are being swept under the rug (at least from our perspective). Maybe they are actually going with the 300 meter expansion compensation at the ends of the track - If so, I can't wait to see how that works out...
It will be 1000x safer than a car, and honestly you would probably have a better chance tripping and injuring yourself than any issues here, it is probably super safe.
Don't you love it when haters are bitching about world changing technology's missed target release date? It is changing the world for the better, THAT is the point, not that it is being released 3 years later than expected. Do you even know how insignificant 3 years are on the grand timescale?
Why above ground? Why not dig a big trench and install 9 tubes. (3x3) Then build a highway over it. I’m excited to see it get build but don’t want to look at it everyday once it is.
Better if vehicle pod takes up nearly all the space inside the airlock, That way it will displace most of the air you would otherwise have to suck out and therefore speed up the process of getting in and out. They also have to address the rescue plan should things go wrong and they have to re-pressurise the tube to atmospheric pressure to perform a rescue. The system should be sectionalised with isolators so if you do have to re-pressurise the tube, you can do just a small section where the vehicle is stuck. I hope they test what happens to the pipe if a section gets damaged as this could propagate a collapse of the whole tube killing everyone inside it.
My thought on the whole vacuum tunnel issue is that it poses a huge engineering and safety challenge. Not creating the vacuum, that's pretty straight forward, but making the transports essentially as strong and reliable as space ship capsules - well maybe not AS strong due to less stress, but absolutely have to be far more reliable than any form of mass transit system ever built, which could drive costs way up. If you get a leak in one of the pods, the passengers could be dead within a very short time unless there's some way to almost explosively repressurize the tunnels which would shut everything down as well as dangers associated with that. Then how to get to them to rescue them - access points would need to be built practically every kilometer possibly (with extremely secure safety locks to prevent tampering) and other issues I can't think of at the moment. I trust they've already thought of this, so if they're continuing to work on this then they must have answers I suppose ;?)
Russell Popham How do you rescue people out of a ten kilometer long train tunnel? If that is possible it shouldn't be impossible to rescue people out of tubes with easy access to them.
Should really just use this for commercial transport (amazon packages) until ALL the bugs are worked out.
exactly! finally someone among the dreadfully negative comments that gets the process!
How does everyone else in this section thinks roller coasters are tested?
Stephen Kramer That's how they're going to make a profit initially. Cargo transport makes $$$. India and the Middle East have shown interest.
Sure make a tube network under all the roads linking every address then commerce is better right? Only when it doesn't jam I guess.
Yes, so when it blows up it doesn't kill everyone inside.
Vaccum is only less than 15psi
The hypeloop will be absolutely fast, safe, cheap, comfortable, and environmental friendly. Not to mention it will generate more energy than it needs. On top of that it's easy to build, that's why Elon Musk is letting students build it. "It's not that hard."
Why does that sound like a scam? 🤣
How much oxygen does a car carry since you are traveling in a vacuum?
My Farts will be glorious!
atmospheric inside, and the outside is not a vacuum, it's just lowered pressure.
None? Why would you need it? Get educated.
Think of the ISS, they generate oxygen in space as required for months/years on end. The same could easily be done in a pod. We are a long way from people getting in, they'll experiment with cargo for years.
yeah cause you don't need to breathe right?
The shuttles will carry enough oxygen for normal operation just by volume, but there will likely be a backup in case of a holdup.
what that backup is is still unclear, but it could be a pressure bottle with oxygen for example.
ps if you say something stupid like "get educated" help people do so then.
Two questions:
1) How long does it take to pump down a 100 mile tube? It must take weeks. That's a lot of disruption if vacuum is lost, and they have to pump it back down.
2) Imagine you're half way there and the car breaks down. How long till you run out of air? Suppose a car's seal breaks, how long till you die from vacuum exposure (probably 10 seconds?).
i mean airplanes are just as dangerous if they rupture think about it
no they are not.
Loving the comments about how dangerous and impossible Hyperloop is :)
I wonder if these people have ever traveled in one of those flying, pressurized, winged tubes at 38,000ft in the sky? At 600mph.
With up to 36,000 gallons of jet fuel stuffed into the wings and under the cabin.
What about a metal box with wheels that travels up to 70mph with nothing but a cage, nylon straps and bags full of air to protect you? Oh, and you have to operate it. And also, there are thousands of other people operating them all around you at all times. And some of them suck at it.
And you really worried about a vacuum leak? THAT'S the thing that scares you? What exactly do you think would happen if it depressurized?
What is it EXACTLY you are so afraid of?
it will shoot you out of the tube like a giant rail gun traveling at the speed of sound? theres nothing to hit in the sky, existing transportation working is not an excuse to put yourself in obvious danger.
that "existing transportation" used to be a horse and cart.
Going from horse and cart to combustion engines is a lot different than going down a giant railgun at the speed of sound. Under that logic, I could shoot myself out of a canon because `airplanes are too slow` with zero regard for safety. Combustion engines became popular, but did you ever hear about the forms of transportation that failed? Look up selection bias, you've excluded all the situations where transportation ideas haven't worked out. Example: Bennie Railplane (a monorail which was powered by a propeller). I get that innovation is important, but the hyperloop is a perfect example of "good in theory, bad in practice". Example: How is a 350+ mile long tube going to deal with thermal expansion? Cars driving into the support pillars causing vibration/damage? What happens in the event there is a loss of vacuum? It would be more practical to build a giant high speed railway like in Japan which is just a track.
Well sir, do you think engineers haven't thought all of these things you are afraid of? I'm sure they are working on security measures for pressure loss, for thermal expansion, vibrations etc. With that i mean, give them a try. Don't judge the project without knowing.
(Near)vacuum is nothing near air pressure at 30 000 feet. Ever seen explosive decompression victims? Look it up. Besides, it's not as dangerous as it isn't economically feasible. Build a 600 mile long vacuum tube with operating costs lower than an airplane and only then brag about it.
Super pratique mais très laid dans le paysage! En cas de problèmes, on évacuera comment? Ça fonctionnera au solaire?
The cool shit is always in the NV desert......
Unless you have lived there, then you realize everything outside of LV is a empty wasteland for several hours of driving.
Where are the emergency exits?
There aren't any because the tube has little to no air
like futurama...
Jetsons did it first.
Is it in nevada
Fun thought!, alas, sadly it's basically just a better version of a maglev train, not one of those tubes, they work completely differently.
or those things in the incredibles
themrroswell no no just no
how do they manage with the dilatation of the tube ?
Thunderf00t is still not buying it lol
yas
"is still isn't"?
I'm not surprised to learn that you take Thunderf00t seriously.
UnitSe7en I'm not his fan, in a way I'm mocking him, but I'm sure you're stupid to think that every country has English as it's first language.
I'm not stupid enough to not read my own comments for obvious mistakes before posting. You obviously understand English well enough. I know it was an easy-to-make mistake - That was kind of my point.
I'm also not stupid enough to enter an argument about a different language than my native one with a native speaker and expect to win.
It's good to know you don't take Thunderf00t seriously. In my opinion he's not even worth watching as a joke. He's a tiresome bore. I don't really like the Hyperloop concept, though. I think it's a bit whimsical in it's impracticality and a waste of resources.
There's nothing wrong with what he did to scare away the popularity of the hyperloop. Other than like, pretending to be an authority when he isn't, and potentially hindering technological progress by misinforming the public.
How the pipe thermal expansion handled?
YOU MUST CONSTRUCT ADDITIONAL PYLONS
This is an amazing comment. Best comment about the Hyperloop I've read so far.
I'd upvote two times, if I could.
Float it in a narrow canal. Perfect shock absorber.
You made my day!
NOT ENOUGH MINERAS
NO, it's too ugly as it is.. That's a beautiful environment, but, not no more.. Pipelines every where,! Yuk ! Bury it.
For similar technologies, may I suggest the TransPod and Evacuated Tube Transport. You may also want to look up SCMagLev .
Everyone bashed maglev because it was way too expensive, and that was already developed!! And it wasn't point to point. This is rubbish
lol....you are so foolish and short sighted...it is coming...packages first....very cheap shipping, then people
I though the hyperloop tube concept was actually not in a vacuum state ?
But Low pressure, with pods designs with fans in from of it to create event lower pressure/vacuum at the pod location ?
Am I mistaking myself here ?
The US doesn't even have high speed railway. How is this economical?
Because it's basically a better solution to maglev trains.
Maths.
doesn't use taxpayer money for the most part
Lord Lima Bean
That remains to be seen. No company has demonstrated a full system yet, let alone operation and maintenance. The Space Shuttle was a great idea on paper, too - fully reusable, cheap and safe access to space. Reality turned out to be less ideal. Maglev trains are a known concepts, there are data points for actual installation, operation and maintenance costs. No such thing can be said for Hyperloop, so I remain sceptical.
They don’t have high speed rail cause all the cities are super far apart
what number of g was used in swittzerland on board for this secret train ?...in 1982 ...between Zurich and geneva ?...thanks ...
It's green... until you factor in the energy it needs AND its construction resources.
Seriously, just build normal mag rails, it is way better for the environment, and it is actually practical to build on mass, as opposed to trying to build a vacuum system hundreds of times larger than the worlds largest vacuum.
It needs way less energy then a rail one. And you are right it is ambitious but what's wrong with dreaming?
Sooooo how's that 600 mile long vacuum tube coming along? Finished anytime soon? Or are they still toying with na overcomplicated minecart?
Expecting a test traveling video but got another bla..bla...bla...
Expensive to build, expensive to maintain. Doubt it ideal for public transportation.
People probably said the same about aircraft when they first became commercially available.
they are like cheaper, faster, safer, self-contained (power-wise) maglev trains, they are definitely not for everything, but they will have their uses.
Matthew Jenkinson
True, but the difference is, that back then there were no known alternatives. Today we have bullet trains, maglev trains, subsonic aircraft as well as cars. Each of these modes of transportation is well developed, well understood and the pros and cons are known. Hyperloop on the other hand seems to try to fill a niche that arguably doesn't even exist and implementers make bold claims while having nothing to show for it.
Also note that all of the above only refers to Hyperloop as a concept. The first commercial aircraft had the advantage of actually existing and being in operation. To date, Hyperloop is nothing but a concept, a few sub-scale models and technology demonstrators. We've yet to see a test installation, e.g. one that demonstrates the system (including tube, capsule and airlocks), and companies keep telling tall tales about environmental friendliness, low costs and high comfort...
totalermist you realise that Hyperloop is essentially a Maglev train inside a tube, right? With all the massive costs already associated with Maglev trains - but by introducing a vacuum they increase the efficiency of running it. This is the same concept behind a BEV - initial construction is more expensive, but long term costs are much cheaper.
I have yet to see whether it balances out vs a Maglev, but I can see how you might construct the track and run the vacuum pumps for less than the amount you save on energy for propulsion. And it would be able to negate air travel and it's associated emissions on certain routes - would only make sense on high throughput routes, for example.
The trick is you have to compare the construction cost ($ and pollution) versus running an alternative - how much fuel cost is there running jets over a high traffic route for 30-40 years, I wonder? Not to mention engine maintenance, and all the other assorted costs and emissions.
We could probably assume the actual carriages would be similar to a similarly constructed aircraft.
What they're trying to prove is that by introducing a vacuum to Maglev, you can run the train at speeds exceeding that done by aircraft, at a running cost better than normal Maglev. Cross country trips that save you time and money, why wouldn't you like it?
Sure, has to be proven, but it's worth at least finding out rather than just poopoo-ing the idea based on nothing but theory...
If the hyperloop is in a near vacuum, why is the speed of sound a speed limit? Or is the speed just selected for safety?
Earthquakes are the least of concerns facing this project, besides the fact that it is a vacuum which is extremely dangerous they have yet to even address thermal expansion.
Aaron ray
Both are very interesting problems. Good thing they are setting up these test tracks in the hot desert close to California so they can tell us what happens.
I'm pretty sure that those smart people might have come up with a solution by now
The best part of vacuum is that rapid Temperature fluctuation needs a conductor like oxygen or other gases.
edgar hey Like metal tubes.
Most forms of the hyperloop ARE NOT a vacuum, they are just lowered pressure.
they even taped led strips inside the tube to make it look more scientific..
Better to start research on teleportation
Yeah, fun idea, if only it would be possible.
You do know that teleportation essentially creates a copy of you, and destroys the original, right?
Matthew Jenkinson I don't think it will create copy its not time travel, in time travel there might be chance of creating copy but in teleportation case there you just have to invent mechanism to convert physical form into transportable form n again into physical so we are not dealing with time
That's exactly what I mean. With teleport, you don't transfer matter, you transfer information. The 'from' pad will read your matter, turn it into a data stream, send it to the destination where you will be re-created. If you don't also destroy the original, then there will be two of you.
Of course, we may do it using some form of bending of space as with a wormhole - nobody really knows yet.
Matthew Jenkinson this systems will just work like pipe which will transport matter from 1 place to another, if water will be transported form 1 place to 2 then how there will water agin at place 1
The biggest problem I see is that we will only have another form of travel that has to have tsa to go through because of a holes in the world. I hope this can work and want it to work, but I also share many of the concerns that others have like earthquakes, air pump system sufficient enough for ridiculously large volumes. Even. If they did away with the vacuum, it would. Still be advantageous in The tube for lower air resistance. I don’t know what the air. Dynamics would do though with pod shape and tube reactions though. Couldn’t you have a. Breezeway of sorts for the hyperloop where you have the pressurizing section so then you wouldn’t have to re-pressurize the whole system?
Don't you see that the claim by Elon Musk that a ticket will be dirt cheap (less than a bus fare for the same distance) and your comment about people having to open their wallets is a total contradiction? The simple truth is that we know a lot about magnetically levitated trains, we know a lot about pipelines and other big and long tubes, and we can make all the hyperloops we want, except for the fact that it is not economically feasible and it is not acceptably safe for human transportation.
Elon Musk's drive towards making this monumentally expensive endeavor in a dirt cheap configuration takes you to stupid engineering designs, like the lack of expansion joints and the lack of a concrete inner cylinder that would impede the implosion of the tube in case of an accident. This is a textbook case of bad engineering, where you solve the minimum possible number of challenges to get something that works under ideal conditions, ignoring the much larger issues of safe and effective solutions.
Can it turn yet ? Or can only go straight ? Like even the slightest turn? Or a U turn ?
When you build a 1 billion $ track that can be disabled by 1 lunatic with a gun.
Doesn't the same thing go for trains and 1 lunatic with a big rock to derail them?
Sure, trains have been derailed by lunatics, but nearly not enough to stop using them, or even be a valid threat to that mode of transportation.
The thing is when trains are derailed, only that particular train and that portion of track are affected which can be corrected in reasonable amount of time. Here in H'loop, if a dent forms somehow all the outside air is gonna rush in at supersonic speed and will crush the entire tube, right from the point of impact to the very end.
I don't think you're right about the tube being crushed. As far as my physics knowledge goes, air flowing into the tube decreases the pressure, so there would be less chance of a collapse compared to even its original state. Again, that's maybe my limited knowledge of physics.
I do think you've got a good point when talking about a dent. I wonder if the system would notice a dent when there is no pressure loss. An unnoticed dent would be disastrous for any vehicle hitting it at large speed.
Where is the money coming from? Private equity?
Thermal expansion is a real problem for a normal railway track, here you have a tube which makes it very very complex problem to solve. Making it even worse is that every movement (and eventual expansion joints) must be handled without leaks...
Commercial 2021? That is without any doubt vapour hype, empty words for investors...
🇮🇳
True!
I think the best solution to solve this problem is to put the hyperloop underground.There you have the same temperature all time long. And secondary you don't have to struggle with different ground levels
I don't see anything about this project in the engineering press - makes me extremely suspicious that they don't yet have any solutions to these big engineering problems.
Amazingly there are no major engineering problems with creating a vacuum. Building a air tight train is simple, and the speed is guaranteed. Everyone keeps making up fake "problems" that do not exist. So many fake engineers making thoughtless posts.
the speed of sound is inversely proportional to the density of the medium in which the sound travels - the less air the lower the speed ... will certainly be faster than the speed of sound in the pipe ...
I’m American bro I can’t do metric.....
dude i can't even count, wtf comes after ten?
I'm not American and I know metric lmao
If you're not American then of course you should know metric....that a dumb statement dude..
what if I told you I'm from Liberia Africa ;)
I'm an American and I know the metric system quite well.
Is the aerodynamic drag of a high speed train really high enough to economically justify putting it in a vacuum tube?
There's a very simple answer to that... No.
Well... If you pull the cost estimates straight out of your arse then hyperloop is viable. If you don't it isn't.
There are some fast speed trains too fast like 600 kmph. But who doesn't like futuristic transportation. It's cool I mean
arash m this will go double that
How many of them do 1200 kmph? If it can't do 1200 kmph then they need to build it so it can. Wait, they can't build one that fast? Why not? Air friction you say? If there was only a way to remove that barrier...... I am thinking maybe a large tube, underground, with fast trains zipping by. Would not even have to build it through peoples houses, just go deep under them.... yea... that could work.
David Beppler so u agree with hyperloop. ?
There were already projects for maglev trains in a vacum tube.
They have been stoped because they were too expensive.
Chinese companys actually bought this technology recently.
Hardwarehelfer yes it should be expensive. I mean you build a tube as a road.
How humen will get air ?? Are there aircapsuls ??
I wonder when the Hyperloop developers will start talking seriously about the pressures and speed they can actually get away with. Details provided at the start of the project were ambitious to put it politely.
Also how does having very strong supports help keep things steady in the event of an earthquake? The system would need to be very flexible and the strength would not stop the wobbling. If the ground itself is moving things attached to the ground will also move.
I really hope they can make it work but I have an engineering and science background and it just doesn't feel right. Simply put too much energy is required to reduce the pressure to the level needed for smooth movement.
They could probably drop the pressure a bit. Sadly a bit would not be enough to make it worthwhile. It would require a lot of time and energy to drop the pressure 'a bit'.
Anyone who wants the mathematical and physics argument against hyperloop could do worse than check out Thunderfoot's videos on the topic.
Has anyone else noticed that Elon Musk has a hands-off approach with hyperloop yet a hands on approach with his boring company?
Elon seems to prefer tunnels to tubes.
Chriswsm Chriswsm I have to say that your comment, unlike many others I have seen online regarding Hyperloop, is civilized.
There are many educated people such as yourself, who have reasonable doubts, questions. Please, try to take into account that there are people more than qualified working on the project, people with an experience far greater than mine (I also have an engineering background) , yours or your average youtube pseudo intellectual commenter. As absurd as it may look, I'm pretty sure they'll figure it out EVENTUALLY, and as long as they do not share concrete updates, we shouldn't bother too much.
I think earthquke is the least of the problems. There are dosens techniques in use for building shock resistance buildings so it's nothing to study here, they can take an existing solution.
But all of the existing techniques, as the @Chriswsm pointed out, are resolved by becoming MORE flexible, not LESS as I think was alluded to in this video. Pylons would need some sort of independent suspension so that the loop stayed rigid while ground underneath was allowed to flex and move around.
An earthquake should be fine inside it, and the pressure isn't going to be a vacuum or anything crazy like that, just lower pressure, all energy for everything I believe on most versions of this is from solar panels, but you do make good points, I think the whole point of this is less about the thing itself, and more to get all these companies to learn to work together, or at least not be trying to kill eachother as hard, and that there are other ways than to be greedy and be the only one doing an idea.
Mihaila Well spoken
how many peoples in one pod? how many trains in 1 mile?
"The biggest challenges now aren't technical" I suppose that's very true if you think ignoring the obvious and massive technical problems makes them go away. Earthquakes, terrorism, thermal expansion, the fact that if the tube ruptures everybody in the system dies and the infrastructure is destroyed, the fact that the touted economics of the thing are complete bullshit ... Here... Let me just wave my hand and everything will be fine.
Let's be honest here... The idea of a 700mph mag-lev train in a vacuum tube is well within the ability of man if, and only if, you ignore the massive disadvantages of a vacuum tube over a more traditional open air version. The vacuum tube version is lower passenger density, higher energy consumption, costlier to build and many orders of magnitude more dangerous for the passengers all for the sake of saving half an hour in journey time. It's pretty much the same 'theory' as the push for supersonic air travel and look what happened to that.
"higher energy consumption" rofl
Woah! You're right! Imagine what would happen if people would get into large and heavy metal tubes, side by side with tonnes of highly explosive liquids and expect them to lift off the ground... Also sounds pretty dangerous to me...
""higher energy consumption" rofl" Absolutely. The energy it would take to evacuate the tube and maintain the vacuum exceeds the saving on atmospheric drag. The energy cost of creating an almost total vacuum of 0.02 bar are astronomical and the energy needed to drive the proposed turbines on the vehicle (actually molecular pumps) is also astronomical. In fact the turbines will be hideously inefficient *because* they are running in a near perfect vacuum.
For fuck's sake... Evacuate a pipe and then put a turbine powered vehicle in it? Seriously? What ever Musk was on when he thought that one up must be some pretty strong stuff.
"Woah! You're right! Imagine what would happen if people would get into large and heavy metal tubes, side by side with tonnes of highly explosive liquids and expect them to lift off the ground... Also sounds pretty dangerous to me..."
Well in fact early aircraft were appallingly dangerous things to get in but when they crashed they didn't destroy the airfield and every other plane in the air. If I'm on a 747 and something goes wrong I'm in trouble but the 747 behind and the 747 behind that one and the 747 behind that are fine.
If you want a more accurate example think of a subway system like The Tube in London. At peak times there can be a train going past any given spot every three or four minutes but if one train crashes, breaks down or becomes derailed the absolute worst that is possible is that the following train hits it. If it were comparable to the HYPErloop everybody on the same line dies no matter how far away from the original incident they are.
You simply can't get round the fact that the vacuum in the tube is its Achilles Heel. Any breach of the vacuum would lead to the explosive recompression of the whole system destroying everything and everybody in it. And destroying the system itself in the process. The only way to avoid the danger of the vacuum is to not have it and then you're left with a normal train which is what we already have.
How are these fundamentally different from extremely safe airline travel?
Coil wire around the tube. Magets in fron lt and the back and batterys in the middle the cart in large scale
How to waste money. Step 1 ignore thermal expansion. Step 2 ignore the reality that travel time has been massively offset by mobile internet access. Step 3 get some famous guy to talk up this ball.
Edward Scrase internet engineer here
Ezekiel Not really, he just is making sense.
I think it's really unlikely that they have overlooked thermal expansion. That is engineering materials 101. Any somewhat competent engineering firm would recognize the importance and plan accordingly.
DVD playerz DVD playerz step 1: do you really think they're engineering something major like this and haven't thought of thermal expansion. Step 2: with that reasoning we should stop improving our transport system because we have the internet?? Step 3: this 'guy' who's talking it up is a successful businessman, inventor, engineer and intellectual. All things I'm sure you (or me} are not.
Peter. Well I mean they overlooked rust, haven't they...
Does it travel faster than an airplane? What’s the speed of sound?
“the biggest problems aren't technical. It's bringing the people to open their hearts."
That is by far the stupidest thing I heard in a video that centers around hyperloop. Technology and science aren't about believing or not. Hyperloop in it's current form with super long evacuated tubes is no viable solution for large distances. The problems with thermal expansion in combination with sealings, the safety of the passengers in scenarios of pressure loss, the costs, the amount of people that can be transported... The list goes on!
Stop selling this as some kind of dream people need to believe in. Maybe the money can be used for much better causes at some point if the majority finally understands, that this thing will never be "the future of transportation" -.-
The point isn't large distances, the point is a bit shorter distances very very fast, and this isn't the only hyperloop project, there are 12+ companies working on the mode of transportation called "hyperloop" some of them, like this one, have hyperloop in their name, even tho they are not hyperloop.
That line irked me too, it seems like thermal expansion would be a huge problem, and that's assuming they can vacuum the air out of a miles-long tube in the first place.
Lima, what do you mean 12+ companies
So far what I have seen from "hypeloop" is shitty rusted insides of the pipe, super slow pods that can barely accelerate on their own, phisical problems like thermal expasion and general safety when it comes to *near vacuum over long distances* . Also, the inside of the tubes need to be cleaned off from dist and other particles cause its fucking full of them. There is NO working prototype of something travelling REMOTLEY close to the speed of sound in the hypeloop by your 12+ non existant companies.
Thankfully they aren't a vacuum! :D They do lower pressure, not non, they have a fan on the front.
Lima I couldnt understand anything. and your comment doesnt make sense.
Does the inside include paint and less rust this time?
What happens if someone shoots a rifle at the tube? What happens if it fails, and you are stuck inside a passenger capsule? HOW exactly do the rescue teams get to you?
Virgin ? Oh shit I get it 😂
Constant Mathieu ugh
ok so obviously they are using different techniques to levitate the capsule. in an other video they were using air to levitate with a partial vacuum and now they are using magnetic levitation with complete vacuum. you can already tell which model is going to be faster. very interesting.
You want me to get into a vacuum on earth at sea level at 1 atmosphere? Your insane. Does anyone have an education here?
This is John. John has no education. See John try to look smart. Keep trying John.
Fyi you used "your" wrong. You should edit that.
Can't do basic english spelling. Calling out others on education. Yes, you are one smart man.
The hyperloop isn't a vaccuum, it's just lowered pressure, there is a reason there is a fan on the front of it.
Johan W Do you mean English?
lets say all runs perfect and no one shoots the tube , what if a main seal at the connection points fails from thermal expansion and contraction??
Sounds awesome but super dangerous.. maybe build them in a earthquake free zone
I'm more than certain they will keep in mind and account for natural disasters
well, they addressed the earthquake feature in the video.
You are more likely to die from a vending machine than from one of these.
Earthquakes are a non issue. Ever been in an earthquake underground? No? Hint, it is a non-event. Earthquakes only affect the surface. You know, where your cheap home that was built sits. Did you take earthquakes into account before building your home? Is is earthquake proof? No? why not? That is dangerous. You could die.
did you not watch the video...build to withstand earthquakes
How many people can travel at the same time?
Hyperloop in mars or moon would be 🤘🏻🤘🏻🤘🏻
you dont need a hyperlooo on the moon you just have a maglev train that going outside.
Same for Mars. Atmosphere is 1% of earth.
Hyperloop on Mars? What for? To run between those two Martian colonies which don't exist? How about a first step of actually landing a man on Mars first before we worry about moving colonists between the two colonies which we've inexplicably built so far away from each other they need a train. Talk about putting the cart before the horse.
Anthony: I don't think I said anything here that you criticize. If and when Mars gets colonized, the equatorial area will be the warmest and sunniest region, on an otherwise frozen planet. Off planet passenger and freight will best be achieved by way of space elevator. Transport from the base terminal can be fast and easy with hyperloop, especially given the very low atmospheric pressure on Mars. Next time, check with me before you go off making foolish comments.
OK... So *IF* we colonise Mars, because living on a planet with a breathable atmosphere which we evolved over millions of years to live on will be so boring we'll all go to live on a barren rock with no atmosphere and no protection against ionising radiation. *IF* we do that then the hyperloop will be a great idea even though it's pointless as Mars has no significant atmosphere to cause drag...
This is getting quite pathetic. You're using something that's currently not much better than science fiction to support a scheme that is clearly impractical and dangerous in the here and now. We've not put a man on Mars and there's no immediate chance of that even happening... And you're talking about how the colonist are going to get about? What next? The Martian Hyperloop will be fitted with phased plasma rifles in the forty watt range to defend against the Marauding Magenta Mars Mammoths?
Try to attach people as a file to the email and compose..... so i can download them from Alaska within a second.
Proud Of U Anita ....
Love from Your Mother Land 😘🇮🇳
Pay with Dilemma I don't know Abt Her current Nationality but m sur3 She had Roots frm here ...😉
ISMH on this... What if a accident happens and you have to get out of the car or tunnel? Not enough space to Walk out or away from say a fire... Like in subways you have walkways along the tracks to the stations to get out of the system and Air plus Safety people to get too you...
Carroll The outside is only a few centimeters away and there are, from the pictures, hatches on each tube segment.
At some point in the future an error would cause the cabin to depressurize and some unlucky passengers will die horribly.
hept As if there haven't been accidents in the past with every mode of transportation known to man.
So we shouldn't advance because someone might die, maybe.
If this is safer than other forms of transport (wouldn't be hard to beat car travel), then that's a good reason to do it.
Just like in planes there would be emergency oxygen.
They can't exactly hijack a railed vehicle and crash it into a building.
true but you're saying that as if there haven't been crashes and horrible deaths caused by other modes of transportation. example: DRIVING... even planes crash once in a while. planes are statistically the safest way to travel but when they crash, you don't see people saying "im never going to fly on a plane ever again because of that one extremely rare crash"
Would it be able to go underground or under water?
Thunderfoot>Hyperloop
And you'd be right. Well done :)
What a tool
Hey that's constructive Chrissy, i bet you're a smart person.
Have you watched TFs videos on the subject? That's my evidence. "simpleton contrarian" Great point, boy you sure know how to put a guy in his place.
Terrorball thunderfoot is a chemist who has been debunked regarding the hyperloop several times, please watch the hyperloop debunked - debunked videos
how will they cool the rails, plus it would be very expensive to do so, which in turn would make travelling in this too expensive
magnetic levitation hello are you awake
yr, but it uses switch of current to distort magnetic fields to create current, in return generate heat on the track, this is the problem facing maglev trains, plus it is very expensive to cool
to me the hyperloop just seems like an unnecessary waste of time and money
thats what they said about planes
Werberjerbins how long are you going to keep up that strawman argument?
It has advantages over plane travel. Weather will not be a factor, for example.
Filthy: Not California, Nevada.
They also pretty clearly stated that earthquakes were taken into consideration. The people behind this aren't idiots, of course they know to be weary of shit like that.
They might have told you that there are no more significant technical problems, but that's definitely not true. I'm really curious if they are blind for the obvious problems or they ignore them for some reason.
Hyperpoop...
why tho
i wonder too..
Don't you have brains to think why? For too many reasons... Too expensive to build at a national level. Not profitable. Dangerous.
This, like many other bs projects that are seemingly coming out nowadays, is very unrealistic at this point in time.
wow clearly you're stupid, not surprising. You're part of the dead weight that impedes human progression.
Ah! Okay, little smart man! You clearly know more than my father... You apparently know more than an engineer. Sorry... I didn't wanted to insult your intelligence with my dead weight mentality. Again! Please, forgive me!
Why not just make it so that there are 2 long tubes one way tubes. One for each direction. Then have feeder tubes branch off of the main tube? Like a subway system but with airlocks. Even if you need to have airlock doors at the junction points that would open only when needed between the main line and the branches.
Needs to be burried underground cause it looks ugly
hahahaha.
Seems some of the biggest hurdles that are delaying these projects is strictly bureaucratic - permits and cooperation from all the different city, state and federal agencies are typically a quagmire.
No, the biggest problems are steel expansion and compression, and rapid depressurization would kill everyone on the line.
Too expensive. This will never be the future
You dont even know the price... Wtf
Based on previous reports it will be cheaper than current train technology.
That is what I thought when I first heard about it too, but after some more reading, it actually makes a lot of sense, it's basically just a cheaper maglev train that goes faster.
INSAF why can only a few use it at a time? Why do you have to wait ages?
Bet people said this about aircraft in the 50s too...
what if someone shoots at it? wouldnt that leat air in it?
I would take the hyper lube over an airplane but the question is, would I have to remove my shoes 1st, before boarding?
this will never be mainstream
a infrared light beam could be used to detect any object in the tube when traveling so fast
We can use this tube to send fresh vegetables from California to Vancouver, BC, Canada
It's going to take A LOT of materials to build this between cities or even countries. It's very cool though and is without a doubt be a part of the future in one way or another.
So it's at 100 Pascale they don't use the concept, where you use a prop at the front
scary. you cant jump out of it if it gets stuck. Isnt there a window? Why can't they make the tube transparent
they said their will be escape hatches built in the tube every so many feet for that sort of scenario
Is hyperloop one only going to be one way???
Boone Tibbitts They will probably always be built in pairs.
No way in hell I'm getting into one of these pods. Airplanes and trains are claustrophobic enough thank you.
i think the ground pillar for supporting/holding the vacume/vacuum pipe should "A" or "H" type should not " I " type ...
They should be focused on THERMAL EXPANSION rather than the passenger experience. Or have they solved that? I'm a big fan of this concept but it seems like the hardcore engineering challenges of creating a 600 km (San Fran-LA connection) are being swept under the rug (at least from our perspective). Maybe they are actually going with the 300 meter expansion compensation at the ends of the track - If so, I can't wait to see how that works out...
Seems cool but I am not sure if it's something I would want to travel in but if it's super safe than maybe🤔😃
It will be 1000x safer than a car, and honestly you would probably have a better chance tripping and injuring yourself than any issues here, it is probably super safe.
That woman speaks so fast!
Don't you love it when haters are bitching about world changing technology's missed target release date? It is changing the world for the better, THAT is the point, not that it is being released 3 years later than expected. Do you even know how insignificant 3 years are on the grand timescale?
don't you think people will be a bit scared of being stuck in an airless tube? if something were to go wrong?
WHAT’S THE SONG?!
For this project to get enough support it needs to have feasible airlocks to significantly reduce the amount of air that the air pumps need to remove.
What they have thought at time of emergency n evacuation
There are several companies working on iterations of this, it depends on which one
Lord Lima Bean how?
The real question is why aren't the tubes translucent
For a second I thought this was one of those atom smashers and I got really excited, then the hope died down.
Why above ground? Why not dig a big trench and install 9 tubes. (3x3) Then build a highway over it. I’m excited to see it get build but don’t want to look at it everyday once it is.
Better if vehicle pod takes up nearly all the space inside the airlock, That way it will displace most of the air you would otherwise have to suck out and therefore speed up the process of getting in and out. They also have to address the rescue plan should things go wrong and they have to re-pressurise the tube to atmospheric pressure to perform a rescue. The system should be sectionalised with isolators so if you do have to re-pressurise the tube, you can do just a small section where the vehicle is stuck. I hope they test what happens to the pipe if a section gets damaged as this could propagate a collapse of the whole tube killing everyone inside it.
anita sengupta, omg, Hyperloop One got a superspaceengineer
she is Indian i guess!!...so proud
They talking about building one in Missouri. I think I just rather travel on Amtrack. We'll see.
Earthquakes?
My thought on the whole vacuum tunnel issue is that it poses a huge engineering and safety challenge. Not creating the vacuum, that's pretty straight forward, but making the transports essentially as strong and reliable as space ship capsules - well maybe not AS strong due to less stress, but absolutely have to be far more reliable than any form of mass transit system ever built, which could drive costs way up.
If you get a leak in one of the pods, the passengers could be dead within a very short time unless there's some way to almost explosively repressurize the tunnels which would shut everything down as well as dangers associated with that. Then how to get to them to rescue them - access points would need to be built practically every kilometer possibly (with extremely secure safety locks to prevent tampering) and other issues I can't think of at the moment. I trust they've already thought of this, so if they're continuing to work on this then they must have answers I suppose ;?)
Russell Popham How do you rescue people out of a ten kilometer long train tunnel? If that is possible it shouldn't be impossible to rescue people out of tubes with easy access to them.
this was basicly none informations, because there are guys who got much deeper into it
có thể xây dựng ở Vietnamese không. từ sài gòn về đồng bằng sông cửu long đi xuyên qua cánh đồng ruộng
So it is faster by 300 km/h than maglev trains in japan just by putting train in the vacum... Seems straight forward.
Where is it being built
several places are building their own versions of this, it is an open source thing that several companies are building.
I enjoy walking, thanks.
Excelent move transportacion now👍🙋♂️🙏
