Hyperloop sounds like a bunch of hype. High speed trains are a thing already, as are MagLev trains, as are trains that go through tunnels, called the subway. The lack of their success in the US market has little to do with the technology itself and more to do with politics. The addition of vacuum tunnels does little to alleviate the administrative / financial challenges of our struggling train systems. Vacuum has few practical upsides and a lot of downsides such as safety, reliability, and cost. It boggles the mind as to how investors are falling for this idea. But perhaps marketing and branding are where Musk/Bronson's talents lie when it comes to high-speed rail? Please tell me otherwise, as I would love to see better rail infrastructure in the US.

    I feel like this doesn't quite work. The vast majority of people may be for trains but there are so many points of local veto. If a train/hyperloop needs to cut through a neighborhood in order to avoid taking a 5 mile detour the 20 people effected are going to use everything in their power to stop it - who can blame them. Even road expansion is slow and costly and hard to navigate.

  I think the goal with the vacuum is to get to even higher speed rail which can compete with airplanes for speed and convenience. The thought being, rail has to be clearly better than flying for it work. That said vacuum comes with many technical issues.
  - timerol 6y ago
    The Northeast Corridor is wildly profitable for Amtrak (based on operating costs), despite being significantly worse than flying, and often slower than driving. (It's faster than rush-hour driving, but that's about it.) Making fast-enough rail that connects useful places, and upgrading the speed of existing rail that meets the same criteria, is a much better strategy IMO than trying to do "better than flying" rail based on unproven technology. Moonshots have their place, but America should try to catch up to the rest of the world in rail transport instead of pretending we're on the bleeding edge of innovation.

      > The Northeast Corridor is wildly profitable for Amtrak (based on operating costs), despite being significantly worse than flying, and often slower than driving. (It's faster than rush-hour driving, but that's about it.) Worse than flying? I can take the train from Wash. DC to New York City Penn Station, visit my friends who live in the city by walking alone, and then come back home in time for dinner. (Broadway, Time Square, and Wall Street are all walking-distance from Penn Station) The closest airport to NYC center is LaGuardia Airport, off of the island. Then you have to spend money on an Uber (or take the train!) into the city anyway. (Cheapest to Uber to the Purple line, then take the purple line into the city). ------------ The Train's competition is a Bus. There are PLENTY of cheap busses that travel the route. -------- Even if you're off of Manhattan in say... Brooklyn. I'd rather be at Penn Station than LaGuardia Airport. Penn Station has a direct subway line to Brooklyn. Its non-obvious how I'd get from LaGuardia to Brooklyn unless my friends spend time to pick me up (or I take an expensive Uber)

  You're focused too much on the vacuum aspect of the tube, and not nearly enough on the fact that it's a tube, with enough self-support to be elevated on pylons and is an order of magnitude easier to build than pouring a foundation for maglev tracks. High speed rail track is dramatically more difficult and expensive to build than a hyperloop tube system. This was, from the beginning, the huge differentiator between the two. Hyperloop tubes aren't comparable to road or rail bridges/tracks, but instead are comparable to constructing oil/gas/water pipelines. We know how much easier it is already to build those.
  - bigbubba 6y ago
    Hyperloop tubes are pipe dreams, nobody has actually ever build one, so all the pros you cite are purely speculative.
  - jcranmer 6y ago
    > Hyperloop tubes aren't comparable to road or rail bridges/tracks, but instead are comparable to constructing oil/gas/water pipelines. How many pipelines are wide enough diameter to move an entire vehicle and designed to handle the stress of multi-ton vehicles as their dynamic loads? And how many of those are supported on pylons rather than being fully buried?
  - rini17 6y ago
    Roads and rails can have small gaps to allow for stretching from temperature changes. Pipelines solve this with U-shaped segments. Hyperloop can't do either, requires something with airtight-enough seals or some expensive materials. At such high speeds as proposed, any sagging is impermissible (again, unlike pipelines). Of course it's solved engineering problem but it markedly increases the construction price and complexity. So, no, hyperloop is not really comparable to pipelines.
  - soyiuz 6y ago
    See my comment above. An elevated (or submerged) tube with rails (or a track) inside cannot be less expensive than those rails or track elevated (or submerged) alone. I get the pipeline metaphor, but a pipeline with infrastructure inside is just infrastructure + pipeline. So instead of a train system the proposal has always been to build a train system inside a pipeline, which has to be more expensive than either. We have no indication of cost savings here.

  While I agree with your overall point, and I also think that hyperloop deployment is unrealistic, I think part of the idea of the concept of hyperloop is to make high speed rail fast enough for the expansive sizes of America. If you took a 300km/hr train from Orlando to New York City, you’d still be competing poorly with a $100 Spirit Airlines flight. That’s almost 6 hours on the train compared to a 2 hour flight. Even in China where they’ve got the best high speed rail system in the world, most of the major cities are concentrated on one cost with huge populations and you still have Chinese travelers choosing low cost airlines for many longer trips (air travel in China was exploding before Covid). I think what America needs to do is not to focus on long distance rail (which is what the current Amtrak CEO is doing) and to expand intercity high speed rail lines between major cities. There should be high speed rail linking relatively close regions that have clusters of cities. (And of course, all of this is a great argument for making airline tickets pay more for their climate externalities - trains should be more attractive to consumers on price because they’re the lowest carbon form of transport)
  - dmos62 6y ago
    I think you might be underestimating the comfort and convenience of train travel. > That’s almost 6 hours on the train compared to a 2 hour flight. A 2 hour flight also has you getting to the airport early-ish (~1h), going through check-in and/or security (0.75-2.0h, 1.5h average in my experience), waiting for luggage upon arrival and navigating the airport (~0.5h), getting to center city from the airport (~1h). So in addition to 2 hours in the air, there's an additional cost of 1h+1.5h+0.5h+1h=4h, so that's 6 hours in total, and that's best case scenario. I'd choose train travel over plane travel always, provided the trip is not more than a couple thousand kilometers and it's an express. Trains are spacious (in comparison), and you don't experience intense pressure changes, or the bad air conditioning that you have in planes. Air travel tires me out for the rest of the day; after train travel I find myself energetic enough to do things the same day.

  We don't have a solution for flying without oil based fuels (yet). We might get there, but it makes sense to try to develop much faster ground based transportation in parallel. If they efficiently can hit 600mph without risk of obstruction on the tracks, it becomes a contender. Money will become available to develop the infrastructure if flying becomes prohibitively expensive due to carbon offsets and/or dwindling reserves. As a 25-50 year plan it's fine.
- nickik 6y ago
  The original Hyperloop concept avoids the things you mentioned. It does not use vacuum: > The problem with this approach is that it is incredibly hard to maintain a near vacuum in a room, let alone 700 miles (round trip) of large tube with dozens of station gateways and thousands of pods entering and exiting every day. All it takes is one leaky seal or a small crack somewhere in the hundreds of miles of tube and the whole system stops working. > However, a low pressure (vs. almost no pressure) system set to a level wherestandard commercial pumps could easily overcome an air leak and the transport pods could handle variable air density would be inherently robust. It does not use MagLev: > A viable technical solution is magnetic levitation; however the cost associated with material and construction is prohibitive. There are still challenges, but because of the Hype any company doing anything related just calls their system 'Hyperloop' as well. > It boggles the mind as to how investors are falling for this idea. > But perhaps marketing and branding are where Musk/Bronson's talents lie when it comes to high-speed rail? Please tell me otherwise, as I would love to see better rail infrastructure in the US. Musk has not asked a single investor for money for Hyperloop. He likely knows its currently not a great investment. Bronson is a guy who jumps on anything related to Musk and makes a bad copy of it that gather lots of money and then doesn't do much with it.

  I tend to agree. There are a lot of different aspects of market economics and environmental issues at play. The hyperloop, as a concept alone, has value if the marginal cost over conventional methods is supplemented by the increased efficiency in transportation. It will only make sense where predictable constant travel occurs (i.e. NY to DC). The is the same for trains or any other communal means of transport. I primarily don't think it should be a passenger driven technology. The issue with passengers is they don't travel consistently for 24hrs a day. I honestly think a vacuum train for commercial logistics has far more economic viability. A tube from LA to KC,KS or one from KC to the east coast would drop transportation time and labor cost significantly. This is obviously a huge endeavor but, something along this line would allow product to ship half way or completely across the country in less than an hour[1] with availability 24hrs a day. This would be a huge boost in productivity and resource availability. [1] https://en.wikipedia.org/wiki/Vactrain https://en.wikipedia.org/wiki/Vactrain.
  - BurningFrog 6y ago
    Replacing truck or rail transport with a vacuum tube cargo network does sound like it could be reaL useful! Building the tubes is a big cost, but they should be much less intrusive and politically problematic than roads or rail.

  The point of Hyperloop is to provide a shiny new technology that municipalities can use as an excuse for not investing in public transportation, ensuring that America switches to electric cars instead trains/buses/trams/bikes/etc as ICE automobiles are phased out over the next 20 years.
  - nickik 6y ago
    As in the US the majority of people don't demand public transport, I don't see why municipalities would need an excuse. Outside of nerd circles the hyperloop is rally not even very well known so I don't even understand how that would make sense. And 'the point' of Hyperloop certainty never was that, that is just conspiracy nonsense by people who are bitter that most people don't share their opinion. The most you could say is that 'hyperloop has been abused by XY people to avoid investing in public transport' but I have not seen a single piece of evidence for that. Are you really so cynical that every new technology that you don't like, is instantly put to 'ah this is a conspiracy to prevent adoption of what I like'.

I'm very skeptical of this concept because of how difficult it is to build and maintain a massive vacuum chamber that will experience that level of stress over its lifespan. As far as I know, the largest vacuum chamber in the world by volume is the SPF at NASA [1], which is only 37x30m in size. Building such a vessel hundreds of kilometres in length that would have bullet trains going through it multiple times a day seems dangerous and impractical. A single leak anywhere in the tube could potentially cause explosive pressurization [2]. Maybe the Hyperloop is this century's Monorail...

- RobertoG 6y ago
  A hole in the tube would cause air coming in, isn't that the opposite of what that video[2] shows?
- VBprogrammer 6y ago
  Vacuum chambers are generally safer because they don't explode; they implode. Also, the maximum pressure differential is quite low, by definition, around 14psi. Although if your traveling at 500mph towards a section of tunnel which has deformed in any way your are pretty screwed.
- nickik 6y ago
  I don't know about Virgin system but Elon Musk original Hyperloop paper clearly stated: > The problem with this approach is that it is incredibly hard to maintain a near vacuum in a room, let alone 700 miles (round trip) of large tube with dozens of station gateways and thousands of pods entering and exiting every day.

  WB has large expanses of area. It's already being renovated, look at the changes in my home town from 1979 to 2020 - it's gone from a quaint small town to a tourist destination and upscale DC suburb with the Clintons owning a home there ('One of America's Coolest Small Towns'-Budget America). If this experiment works it might enable much more of WV to be considered a suburb of DC. That could be good or bad, but most likely both in different areas. It would definitely be profitable.
  - bigbubba 6y ago
    This is certainly what optimistic WV politicians what to believe, but unfortunately for them there is the problem of Hyperloop being a bunk gadgetbahn that won't pan out and was probably never meant to. (The true purpose of hyperlink, promoted by a man who sells cars, likely being to derail traditional highspeed rail proposals with "but if we wait N years we could build a Hyperloop instead!") WV is being taken for a ride, but not the sort they hope for.

That area's pretty mountainous, right? I always thought that Hyperloop was going to avoid contrasting terrain in the early days.
blisterpeanuts 6y ago
What kind of right-of-way would this system have? If it's sufficiently deep, would they need permissions from every land owner along the route, or could they just bore straight through 100m beneath the surface without affecting anything above ground? >> "a trip between New York and Washington would take just 30 minutes" Would be great, but I'd worry that they will never get the right-of-way to actually bore underneath these huge cities to convenient centrally located stations.

I have to be honest, whenever I read a tech company with the name 'Virgin' in front, I believe that will spend huge amounts of money and not achieve much. Virgin Galactic and Vrigin Orbit are both burning huge amount of money and have really not achieved much in relation to the amount spend. However they are always big in the media and Branson is always mentioned along side of Elon Musk. As if Virgin Orbit and SpaceX are even remotely comparable. As soon as the Hyperloop concept was shown, a company pops up doing it, again making sure the name Vrigin is always mentioned when Elon Musk Hyperloop comes up. Their method and approach often seem more about big hype and big money raising. These companies also tend to find financing from big money people in the middle east, where with a lot of flash and not much substances you can finance. Virgin Orbit is public and promising intercontinental flight, system they are simply not able to develop by any evidence so far, its honestly borderline scamy. This plan of spending 100s of million to develop a short test track seem like the same sort of thing. If it cost this much, how much will it cost from SF to LA? > In a hyperloop system, which uses magnetic levitation to allow near-silent trave In Elon Musk original hyperloop paper, he was explicit not using magnetic levitation. Saying: "A viable technical solution is magnetic levitation; however the cost associated with material and construction is prohibitive." I hope of course they are successful, any attempted at developing new technology is great however I would never bet on them to achieve anything. I still think the Hyperloop as described in the paper is mostly a good idea, but I think its smart of Elon to switch to tunnels. It makes the legal and safety situation way easier. I think the Boring company is actually developing a Hyperloop test track as well, but this is somewhat speculation at this point.

  I don't know about Virgin Orbit, but isn't Virgin Galactic actively testing their aircraft for space flights?

  Replacing truck or rail transport with a vacuum tube cargo network does sound like it could be reaL useful! Building the tubes is a big cost, but they should be much less intrusive and politically problematic than roads or rail.

The point of Hyperloop is to provide a shiny new technology that municipalities can use as an excuse for not investing in public transportation, ensuring that America switches to electric cars instead trains/buses/trams/bikes/etc as ICE automobiles are phased out over the next 20 years.
- nickik 6y ago
  As in the US the majority of people don't demand public transport, I don't see why municipalities would need an excuse. Outside of nerd circles the hyperloop is rally not even very well known so I don't even understand how that would make sense. And 'the point' of Hyperloop certainty never was that, that is just conspiracy nonsense by people who are bitter that most people don't share their opinion. The most you could say is that 'hyperloop has been abused by XY people to avoid investing in public transport' but I have not seen a single piece of evidence for that. Are you really so cynical that every new technology that you don't like, is instantly put to 'ah this is a conspiracy to prevent adoption of what I like'.

I'm very skeptical of this concept because of how difficult it is to build and maintain a massive vacuum chamber that will experience that level of stress over its lifespan. As far as I know, the largest vacuum chamber in the world by volume is the SPF at NASA [1], which is only 37x30m in size. Building such a vessel hundreds of kilometres in length that would have bullet trains going through it multiple times a day seems dangerous and impractical. A single leak anywhere in the tube could potentially cause explosive pressurization [2]. Maybe the Hyperloop is this century's Monorail...

A hole in the tube would cause air coming in, isn't that the opposite of what that video[2] shows?
VBprogrammer 6y ago
Vacuum chambers are generally safer because they don't explode; they implode. Also, the maximum pressure differential is quite low, by definition, around 14psi. Although if your traveling at 500mph towards a section of tunnel which has deformed in any way your are pretty screwed.

I don't know about Virgin system but Elon Musk original Hyperloop paper clearly stated: > The problem with this approach is that it is incredibly hard to maintain a near vacuum in a room, let alone 700 miles (round trip) of large tube with dozens of station gateways and thousands of pods entering and exiting every day. All it takes is one leaky seal or a small crack somewhere in the hundreds of miles of tube and the whole system stops working. > However, a low pressure (vs. almost no pressure) system set to a level wherestandard commercial pumps could easily overcome an air leak and the transport pods could handle variable air density would be inherently robust.

When I think of WV, the main thing I think of is opioid addiction. Other than that and coal mining I don't really know anything else about WV. So, why WV?

West Virginia has cheap land, lots of undeveloped areas, and republican government. Way less bs and regulation. More freedom.
- reaperducer 6y ago
  The Republican government is only a recent phenomenon. This is the state that had a Rockefeller for governor in the 90's.

WB has large expanses of area. It's already being renovated, look at the changes in my home town from 1979 to 2020 - it's gone from a quaint small town to a tourist destination and upscale DC suburb with the Clintons owning a home there ('One of America's Coolest Small Towns'-Budget America). If this experiment works it might enable much more of WV to be considered a suburb of DC. That could be good or bad, but most likely both in different areas. It would definitely be profitable.
- bigbubba 6y ago
  This is certainly what optimistic WV politicians what to believe, but unfortunately for them there is the problem of Hyperloop being a bunk gadgetbahn that won't pan out and was probably never meant to. (The true purpose of hyperlink, promoted by a man who sells cars, likely being to derail traditional highspeed rail proposals with "but if we wait N years we could build a Hyperloop instead!") WV is being taken for a ride, but not the sort they hope for.

That area's pretty mountainous, right? I always thought that Hyperloop was going to avoid contrasting terrain in the early days.

blisterpeanuts 6y ago

What kind of right-of-way would this system have? If it's sufficiently deep, would they need permissions from every land owner along the route, or could they just bore straight through 100m beneath the surface without affecting anything above ground? >> "a trip between New York and Washington would take just 30 minutes" Would be great, but I'd worry that they will never get the right-of-way to actually bore underneath these huge cities to convenient centrally located stations.

I have to be honest, whenever I read a tech company with the name 'Virgin' in front, I believe that will spend huge amounts of money and not achieve much. Virgin Galactic and Vrigin Orbit are both burning huge amount of money and have really not achieved much in relation to the amount spend. However they are always big in the media and Branson is always mentioned along side of Elon Musk. As if Virgin Orbit and SpaceX are even remotely comparable. As soon as the Hyperloop concept was shown, a company pops up doing it, again making sure the name Vrigin is always mentioned when Elon Musk Hyperloop comes up. Their method and approach often seem more about big hype and big money raising. These companies also tend to find financing from big money people in the middle east, where with a lot of flash and not much substances you can finance. Virgin Orbit is public and promising intercontinental flight, system they are simply not able to develop by any evidence so far, its honestly borderline scamy. This plan of spending 100s of million to develop a short test track seem like the same sort of thing. If it cost this much, how much will it cost from SF to LA? > In a hyperloop system, which uses magnetic levitation to allow near-silent trave In Elon Musk original hyperloop paper, he was explicit not using magnetic levitation. Saying: "A viable technical solution is magnetic levitation; however the cost associated with material and construction is prohibitive." I hope of course they are successful, any attempted at developing new technology is great however I would never bet on them to achieve anything. I still think the Hyperloop as described in the paper is mostly a good idea, but I think its smart of Elon to switch to tunnels. It makes the legal and safety situation way easier. I think the Boring company is actually developing a Hyperloop test track as well, but this is somewhat speculation at this point.

I don't know about Virgin Orbit, but isn't Virgin Galactic actively testing their aircraft for space flights? [1] I think it's a bit of a stretch to either call them a scam or argue that they didn't achieve much. This area has so many regulations it takes decades to innovate and go from idea to market.

Note that the article states this will just be a 6 mile test track inside of a former coal mine, not an real-world system for transporting passengers from one part of WV to another.

I can't imagine WV will ever get much investment in public transport with their population density.
