Just a thought, high speed trains in France have a commercial speed of 320km/h (although they can actually go over 500km/h but it's deemed unsafe). So you'd make the trip between Dallas and Houston in roughly 1h15min. With a train that already exists, on regular tracks.
yeah its not a dumb idea but why do that when you can go from Dallas to Houston in 30min?? I see the point in that the tracks allready is built, but its not efficient compared to hyperloop, wich also is relatively cheep
@@boskee Elementary physics says that hyperloop is possible. And it has been tested successfully. And elementary physics is not research last time I checked.
I came up with a plan to do it in zero seconds. I'll tell you how. Call both cities New York and LA. Therefore you are already there. I have other ideas.
certainly, the non stop acceleration, like sitting in a couple G's simulator, would not be a comfortable trip! Although, they could put you in a fluid, and "depressurize" the fluid... if thats possible as fluid isn't exactly compressible; to reduce the sense of pressure you would experience as the fluid "compresses".... IDK. Just ideas. Actually, it would be the fluid compressing the air in your body.. so create a vacuum outside of the fluid, to maintain the internal pressure your body experiences. Something I never thought about... Could you leverage fluid dynamics to reduce the effect of G's on the human body? maybe increasing the surface area so there is less pressure per square inch, so the tank absorbs more of the pressure! But... Were talking about inertia... so you're body is still gonna experience a flattening of itself internally, even if the surrounding is designed to accommodate non-pressure points... hmmmm...
@@AB-wf8ek You don't. Assuming constant acceleration and deceleration over the 2460 mile great circle route between New York Laguardia and LAX, and ignoring centrifugal forces, the acceleration is 1793.6 times Earth's gravity to a speed of 263.9 km/s and back to 0. That speed is 23.6 times Earth's escape velocity. Your bones will have collapsed under that acceleration. Not wanting to do the calculation, I think the centrifugal acceleration trying to follow the curve of the Earth through a tunnel through the Sierra Nevada, the Rockies, the Appalachians, and other minor mountain ranges and hills is going to be fairly significant.
The biggest problem with Hyperloop has always been, and will always be, that any savings you get from travelling in a vacuum are going to be more than eaten up by the cost of creating and maintaining a vacuum. A scaling up of the old school vacuum tubes for cargo could be an interesting concept, especially since cargo isn't as sensitive to things like pressure changes, g-forces, or even basic comfort as humans are, so there would be a whole lot less in the lines of design constraints.
I did a school report on this in the 90's. They called them "VHST". Very high speed transit. A train in a vacuum tunnel rides on MAGLEV. They were estimating 14,000 MPH. New York to LA in 30 minutes. I don't know how this became "Elon's idea". He just restated an existing concept and added air hockey.
@Kelly Smunt Lefty types? Last I checked the left were liberal and it was the right who were conservative church-goers, correct me if they've changed the definition...
@@krashd No, but lefties are usually the first ones to be offended by politically incorrect ideas -- or anything else that doesn't toe the liberal line.
Iirc the video of the railcar implosion was made by the manufacturer as a sort of PSA for their customers. The cars are used for transporting dry powdered or granulated products like plastic pellets. These are unloaded by vacuum pumps. There was at least one instance of someone forgetting to open they vent hatch on a car compartment and destroying the rail car. Atmospheric pressure is scary in the right (wrong) circumstances.
I'm starting to come to the conclusion that Hyperloop is just a gigantic money laundering scheme that employees engineers who are happy to work on knowingly impractical cool stuff.
Because the Hyperloop is a scheme to decrease funding for the planned high speed trains in California, in order to get more people to buy new cars (Teslas).
@@TitaniusAnglesmith Good thought. I was thinking it was just a method of extracting money out of gullible\corrupt governments for ‘feasibility’ studies.
GADGETBAHN, noun. A proposed alternate mass transportation system which is based on unproven technology, whose cost estimates are based on wishful thinking and whose main advantage is not being a train.
Because it can cost a billion dollars a mile to erect high speed rain inside developed areas, and no pork bound DNC politico as n worth his bacon is going to pass up the mega pork dinner of trying to cram it into big city slums where they have congressional districts and future ribbon cutting. Contrary to building modern, easy parking, stations our in the burbs or countryside to benefit a RNC district and demographic. So it becomes a partisan issue as well as a pragmatic practical one. Oh I'd like to run a 350kph train through your backyard after condemning your land, but not give you as station unless you drive two hours into downtown Atlanta, Indianapolis or Cincinatti to catch the bullet train and pay $50-$90 a day to park while on holiday. .
In the US? Trains don't make any sense. High-speed trains are a little too slow and too expensive, so we only have a couple of transit corridors that would work. Land prices and labor prices are both very high, and because only a couple corridors could make a profit, we don't have the economies of scale to drive construction costs down. Airports are a better solution to that problem, because they connect individual cities without needing tons of infrastructure. Hyperloop makes sense in the US because it's faster than airplanes, so it has a market niche for people who absolutely need to get somewhere as fast as possible.

Fusion is a stupid idea, because even if it works, you can't really remove the energy from the plasma and the radiation is destroying your torus, but can't be decoupled from it.
hmm yeah, not viable at least for now. Hyperloop is just a science/engineering "experiment" for now, HSR (like Shinkansen, ICE & TGV) is more practical as it is already proven.
one of the reasons why I love your channel is you always explain everything in detail and easy way to understand like seconds before the "What is Maglev?" section, I literally just said to myself "okay, what's maglev? *confused face*", and then you are there to answer it lol thank you for not leaving us clueless person behind, Joe 😂👍🏼
@@KateeAngel Um..no. other countries do not. If they want a railroad through you property, they build it and you move. lol also my fav hypeloop has no problem. Unless you want to sell the interstates to the highest bidder?
High speed rail is horribly inefficient for sparsely populated areas. There are perhaps two corridors in the entire US that would be economical. Even regular rail is terrible for passengers in most cases, and within metropolitan areas buses are better in most ways. Turns out using existing infrastructure is easier. The US isn’t Japan, China or Germany, all of which are several times denser. Most of Western Europe is considerably denser too.
@@ericlotze7724 sure...until you realize that even the largest zeppelins had a minuscule carrying capacity. far less than just a normal cargo aircraft, and are much slower, and unreliable in bad weather. they didn't work for a reason, they just weren't competitive and didn't make sense when compared to the speed and efficiency of aircraft, and the massive and cheap cargo ships.
@@livethefuture2492 I can see this tech being used to air-drop critical things like paramedics, or emergency equipment in urban areas. Maybe flying fire-control too? Or if you're gonna be a capitalist about this, amazon did say they would use blimps as flying warehouses. But I like the idea of airborne emergency services more.
It's like saying ''calculate the cost and effectiveness of renewable energy and you'll see that coal is better''. Hyperloop is still a prototype so just wait and in a few years there are solutions for every problem
add on to that the energy needed to keep the vacuum, cycle the airlocks, etc and you know it's rubbish. Now work out what happens should someone put even a small hole into the tube. You know that in the USA, a tube above ground will be shot at.
@@eliasmok3261 "Hyperloop is still a prototype" Nope. Unless you mean that silly test track? " there are solutions for every problem" Yes there are but the solutions for the hyperloop are not viable. Do the math.
The other folly is the passenger vehicle would have to be built to space craft standard to withstand vacuum environment. It would have to carry air supply and CO2 scrubber. And it would be a good idea for passengers to wear space suits for redundancy just like astronauts. Contrast with airline fuselages which do not need to withstand vacuum and use pressurized external air for passengers to breathe. HL really is a folly.
They both reached the same conclusion, ultimately coming down to its economic viability. It's unlikely that selling tickets is going to be able to the cover the costs of building and maintaining the system. The light at the end of the tunnel is when we ditch the impracticality of the vacuum tube and start to build maglev trains right here in America.
I had watched Thunderfoot's video on it before, and this was a fresh take for me. I got the same information without the seemingly condensing nature Thunderfoot brought (that's just how I perceived him) to the table. And that helps a lot.
Thunderfoot has a hate boner for Elon for some reason. His videos are riddled with serious errors, he didn't do even a basic research. So ignore everything he said and think for yourself instead. For example I love how everyone just assumes it won't be economically viable, without doing any kind of calculation. The only calculation I saw is from Elon Musk and his engineers. They know how much it costs to build stuff, because they are in the business of building all kinds of stuff. According to them the original Hyperloop would have cost ten times less than California's new high-speed rail line. That was the benchmark. Even with significant cost overruns they would have beat it easily. And the new design with tunnels is probably cheaper, because a big part of the cost is just acquiring the necessary land.
@@andrasbiro3007 A big part of the cost of California's rail was mismanagement. That played into the cost overruns. So it might not be the best comparison, as not all of it was due to construction based purely on the design.
@@foggs In this video Joe also mentioned that misconception about vacuum. Like if you make a hole in a vacuum tube the whole section will be destroyed. The truth is the air will just pour into the tube through the hole the same way water will pour into a submarine if you make a hole in it. And by way to handle a vacuum, you just need to handle an atmosphere of pressure meanwhile submarines can handle tens atmospheres of pressure it is just a matter of design strength.
@@pawelzybulskij3367 would be interesting to see that simulated - various projectile sizes at different speeds fired at a vacuum tube. It must fail catastrophically at some point
@@pawelzybulskij3367 Actually, pressurized liquid and gas vessels do not pose the same thread. For a given pressure and volume, gas vessels contain much more energy (as fluids are not compressible), a rupturing gas tank can explode like a handgrenade, whereas a rupturing liquid tank releases a stream of liquid. That's why every pressurized vessel is being filled with liqued upon being pressure tested. However, i too think, that Thunderf00ts arguments are not even close to being valid. I mean, just look at the ISS, it gets bombarded by tiny pices of metal, that travel multiple times the speed of a rife bullet and the structural hull is only Milimeters thick. If that's not enough, we build fucking gas tanks for cars that withstand 300 to 700 times the pressure difference that the Hyperloop would have. The only real downside to the whole concept (in terms of cargo transport) is to maitain the vacuum.
Joe isn't as closed minded as Thunderf00t, he understands original concepts drive innovation and technology. It isn't very good yet, but neither were internal combustion engines, airplanes or electric cars in the beginning.
@@garyedwards5345 Take away the vacuum tube and the pods and what you have is maglev trains - which is already well understood technology (though it could do with more cost refinement). Add the vacuum tube and the pods and what you get is something that is more expensive and carries a tiny fraction of the number of people. It doesn't really matter how you engineer it, its simply wrong economically and can never be fixed, no matter how hard you innovate.

@@carletpierre1895 So yea, I remember just a little and dont care to see it again, but he actually went full scientist to create a small experiment to show the deadly vacuum. The problem was that he showed it on ball bearing in a slightly larger glass tube. His experiment could be made safer just by making the tube a tad bit bigger, or by the fact that the train is actually not a giant freaking ball. it could have a brakes or whatever.. the point is that his point was even more easier to disprove that the whole concept he was disproving - making the criticism stand on even shorter legs. Disproving shitty science with even shittier science is not very good way to go.
In the 1890's a vacuum system with the tube being approximately 1 metre high carried mail from Euston station to Highgate in London. employing a wheeled trolley. The system ran for about 11 years when it was abandoned because the vacuum sucked ground water into the tube
@@joefox9875 I was on the supervision staff as a junior engineer of the Euston station construction. The contractor broke through the tube of which the cast iron was of the finest. In fact I stated the tube ran to Highgate which was in error. It ran to Holborn.
@@noneyobiz337 Not sure if it would actually rip them out, as the iron is individual atoms within a molecule, and human tissue is pretty strong. But you know how an induction stove only heats up magnetic metals?........ The magnetic field would also "drag" the iron to follow the field lines. That would be bad for moving oxygen. But magnetic iron doesn't move oxygen.
I appreciate and enjoy this channel a lot. Thanks for the background and honesty that Musk is no longer behind this project and how the tech being tested has now changed (as I knew Elon's idea initially in his 2012 white paper was totally non-viable). One tip for Joe, I know you're an Elon fan, but please keep including some of the cons on his projects as you go forward. He isnt perfect; a lot of his actions very negatively impact the environment and show a lot of bad attitude character traits. I also know most others are like this too, all big companies negatively impact the environment, for sure. Many, not all, innovators also have a bit of an ego. Elon just seems unable to admit his weaknesses! I find that troubling and interesting.
I was scrolling just to find a mention of him. He regularly destroys the vacuum tube part of this thing. Its also enlightening to see what happens to an oil tank car under vacuum!
Nope. His argument is actually pretty terrible, unfortunately. It's frustrating because he seems pretty realistic about things - it's just that he doesn't have any perspective at all on the engineering challenges.
@SAMUEL NAUMETS Thunderfoot's video is the same thing - hot garbage. The tank implosion video is basically misinformation, and the argument made is completely wrong at a really fundamental level. The reason tanks implode like that is because they're only designed to hold pressure from the inside, like a balloon. They're not designed to hold a vacuum, so they don't have safe failure modes and look catastrophic. The logic being used is like trying to push a rope and assuming you're the strongest person in the world because it bent. Vacuum pressure is not that hard of a design problem, pretty much any underwater tunnel is much harder to build.
@@louisvaught2495 a hyperloop from la to San Francisco would need around 60,000 vacuum pumps, not exactly the most economically sustainable vision now, is it? Also, thermal expansion.

I feel like Hyper-loops are going to end up like Zeppelins, they were awesome, revolutionary technology that had a lot of economic and technical issues. Eventually the Hyper-loop tunnel will collapse and it will be like the new Hindenburg
That's assuming that it will ever be built. Considering how scammy the two developing companies are acting and how many predictions they put out went by without anything happening, I won't hold my breath.
@@hifijohn Worse than the Concorde. The Concorde _was_ built, it worked technically, and flew commercially for 27 years. I'm pretty certain that no commercial HyperLoop will ever be built, there are too many technical and financial obstacles before we even get to face the insurmountable economical, safety & maintenance problems.
There are technical questions about hyperloop that no one ever discusses: 1) What are the passengers going to breathe? They could breathe oxygen from bottles that someone has fill each trip. CO2 buildup will require a scavenging system (that has to be maintained frequently) 2) How are they going to cool the pod? Air conditioners have to reject the heat somewhere, normally by blowing air over the condenser. Can't do that in a vacuum. 3) Airplanes operating at high altitudes are required to have a back up oxygen supply (masks that drop out of the overhead)- won't the regulators require the same for pods traveling in a vacuum? That's a minor issue, but airliners are also required to have a stewardess to explain how to use the emergency oxygen... and point out the emergency exits... 4) Where are the emergency exits in the 300 mile long vacuum tube? There are other technical and regulatory issues, but those four are enough to scuttle hyperloop. The maglev train in Shanghai is great, but it's so expensive to operate that China only runs it at full speed twice a day. They have scaled back their plans for a large maglev network and will use wheeled high speed trains over most of the planned maglev routes.
The oxygen supply from the masks on a plane is just a chemical reaction that only lasts like 12 minutes or so. It’s sodium chloride, potassium something, and something else. No idea if that would be required for a hyper loop like system but it would be negligible to add.
Which means what exactly? Its fairly easy to go through his videos and find tons of errors or outright lies that he tells by relaying accurate data and making unjustified conclusions from it. Mason is sitting back from the safety of the internet and taking cheap ass shots at the incipient ideas of a new project. And hes not doing it constructively hes just being a troll so his audience will virtually fellate him harder in the comment section and on patreon.
There was a guy who worked for Strawbridge and Clothier in Philadelphia as a maintenance man who took his 15 minute breaks in a closet. Long after he retired they were doing some work and someone discovered that in the closet, a pneumatic tube ran through the closet and that there was a gate installed in the tube that could be easily opened. It was never proved but it was thought that this maintenance man spent his break period interrupting the cash from the checkout counters and skimming a little. Apparently he was smart, in that he never took so much as to cause suspicion. The word was he retired after 30 years and lived a life that was way above his station and had passed away by the time they discovered the glitch in their pneumatic system.
For hyperloop to work, the trains have to also work without a vacuum. Of course, this would be at reduced efficiency, but if the entire train can be disabled by even a section being depressurized we have big issues. Maybe the sections of rail have doors every now and then that can close to prevent mass depressurization, or open to allow air into a section if an issue arises for a train.
The animation you show around 6:05 is misleading, because it actually shows a magnetic levitation system instead of a pneumatic one. The arrows indicate a Halbach array configuration.
I think he's right on the money with these hyperloop concepts being mainly used for cargo in the beginning. As far as I've seen, a lot of the earliest trains were really only used for industrial transport of goods, and in in cases that I've seen in The UK, the workers would ride along and actually help operate the brakes on the cars carrying the goods they'd harvested/produced on their commutes home every day.

Why does a Hyperloop have to be so limited in speed? If you can evacuate a tunnel down to like 1% of atmospheric pressure, it's not that much more difficult to go to what they call "high vacuum." At a certain pressure (I think it's around a millionth of an atmosphere) not only would any hypothetical shockwaves be exceedingly wimpy, they can't actually be created at all because the gas molecules are too far apart to sustain waves. This also more or less truly eliminates all the aerodynamic drag and you can do it with straightforward turbo pumps. Once you do that, there's no specific speed limit. In fact, the simplest and safest type of maglev (the passive Inductrak type using Halbach arrays) is very efficient at any speed, but actually gets *more* efficient at higher speeds. You could have a system capable of going multiple times faster than an airplane for most of its journey and which also just drops you right in downtown wherever. The concerns around the expense and difficulty of obtaining land rights are real, but can be solved by tunneling. That's particularly appealing if the new system you're making is a quantum leap over the current best alternative of airplanes. Going a *bit* faster than an airliner may not be enticing enough to enough people to sustain a business. But you could charge much more than business class prices for something that is drastically faster. LA to NY in an hour and a half? Houston to Chicago in 45 minutes? That's gold and a lot of people would pay a lot to be able to do that. Basically, I'm not convinced that any of these companies have done serious unbiased customer research. It's a great idea technically, but the burden of proof is on them to show it could pan out economically. I'm just suggesting an alternative whose economics might work out better...

“Just give me a high-speed maglev system.” I totally agree with you on that. We already have the technology to go 300 mph+ on a train today. The cost and complexity and safety issues to put a maglev train in a near vacuum tube to get an extra 200 - 300 mph isn’t worth it. Need to go faster than 300 mph? We’ve got airplanes for that. If we could build an infrastructure with today’s BEST maglev train tech, and pay $45 for a ticket to go from Dallas to Houston in 45 minutes, I call that a win.
Maglev isn’t very practical either. The Shanghai maglev, for instance, loses like $80 million a year. Wheel is easy, wheel is cheap, wheel is reliable, wheel is probably here to stay.
@@edvardbookbratbak5473 Seeing as how there are precisely zero real world examples of a functional “hyperloop,” you have no basis for a cost comparison, Musk’s ridiculous claims of a vacuum sealed maglev system somehow magically being 10x cheaper than a traditional subway system notwithstanding. Until proven otherwise, the “hyperloop” is in the realm of vapourware/fantasy/low realism sci-fi, not reality.
When we do figure out how to "teleport" we will have a problem. You have to disintegrate the original, then reintegrate the clone. Who wants to go first?
i like your expression 'getting shrink wrapped in steel'. the real acceleration one can experience if you open the tube behind the train: you'll be mince meat! energy wise it might be cheaper if you give every passenger his own 737. i was maintaining an electron beam welder of about 0.25 m/3 vacuum content and the effort to evacuate this little volume was amazing.
Imagine if "product tubes" were in every home. When you buy something from the net , it could be arriving at your home in minutes. Size limited of course. Thanks Joe.
One of the joys of train travel is being able to look out of the window. Even if the hyperloop actually worked, it would be a very boring way to travel.
Why? Put on the headset, follow the train from above in 3d with a narration from Leonard Nimoy talking about the plants and animals, even the history of the area. The future is what you make of it.
@@bobthesnowdog9972 why should he? There are just a few points he would not agree to. thunderf00t just see no uncertainty regarding the economics and safety of hyperloop. Joe just did not destroy hyperloop. thats all.
Here's my thought on Boring Co. - Coordinated autonomous electric vehicles in a one-way tunnel can all be moving the same speed. Fans at either end of a route can force air through the tunnel at the same speed as the vehicles. There you got it: no wind resistance, increased speed, greatly improved performance and ventilated tunnels.
"solid" stone isn't actually very solid at all in most areas, and it's saturated with groundwater, it will be interesting to see how they might stabilize the stone enough to hold a vacuum without flooding.
If they wanted to do an underground hyperloop, they would likely still need to line the tunnels with metal. It would be basically the same thing as the above ground version, just with more reinforcement from the ground outside it, less temperature variation, and less chance of impact breakage. On the flipside, any damage that did happen to part of the tube would be harder to repair and would need to be done from the inside. It'd still be impractical, just a bit less so.
Perhaps they could add a "hypercooler" to just freeze all the water solid Once you have the vacuum in the tube, you could then vacuum sputter the walls with Niobium to make the walls super conducting so that the train can be held up by the London Effect.
@@timogul Like I mentioned earlier, there are moisture barriers you can use no problem. But an underground hyperloop wouldn't be very likely due to access concerns. The tunnels would need to be so well-sealed that they would be difficult to access if there's a malfunction. Having it aboveground makes it significantly safer, because you can disconnect a section to access it.
I don't like thunderf00t much. I think he's arrogant. (Come at me bro). But he's correct here. Almost everybody has ditched every novel idea in the white paper and everybody is back to the age-old "train in vacuum tube" idea. Yeah, also people do underestimate how difficult it is to create and maintain a vacuum on earth.
One very cool thing about the Beech train in NYC was that he built the thing right in the middle of the city, in secret. The tunnel was dug out under the existing streets & buildings; it stretched a block or two, & they did nearly all the work at night & snuck the dirt out in secret. Beech ran it underneath the offices of his major competitor.
Maybe not as a measure of transportation here on earth. But if we make a long tube, put a capsule on something like a sledge in it and bend one end upwards in a smooth curve, we might end up with an efficient way to get stuff into near earh orbits.

Got that right. I lived in Midland in the mid-Eighties. It's a real city, though ol course a small one. Nice for most things, but if you ever need something from a big city, the nearest one is at least about 300 miles away. Of course, when I lived there, "I can't drive…55!" had real meaning.
"They want to transport vast amounts of good and people over the Hyperloop. And again, the Hyperloop is not something that you just dump something on. It's not a big truck. It's a series of tubes." ~Sen. Ted Stevens, on the Hyperloop project
Where did Sen. Ted Stevens get his engineering degree? My point is Ted is not a reliable source. Here is an idea, park a segment of tube at a shipping dock, load it like any other trailer that goes on a truck using PIE, launch it down the tube to it's destination. Save billions of dollars in shipping costs. Put thousands of OTR out of work faster than FSD semis.
I think you miss the economics of a constantly available transport vs. airplanes. You find out when your connection from Pittsburgh to Seattle is showing up and 2 an hour. You pick a pod and buy a ticket, show up, get on, and you are gone. You don't need all the logistics of a plane or airport. Just look how constant flow train systems work. You could easily got to Chicago to Pittsburgh back to Chicago on the same day having a choice of three stops in Chicago or Pittsburgh.
to be fair Elons concept was for a pressurized tube that had big blowers blowing the air at supersonic speeds inside a big loop. Honestly makes a lot more sense than a vacuum tube as you don't have to worry about a pressure build up in front of the train unlike in a vac tube (unless it's hard vacuum but they aren't doing that). nor do you have to worry about the train braking the sound barrier inside the tube as all the air is traveling the same speed as the train. Mag-lev is still way better than his 'air barrings' though. but what i don't get is why they all dropped the "pushing the air inside the tube" bit to make the train go faster. we can make wind tunnels that have air flows over 5000 KPH, just think of making a wind tunnel in a big loop with rail tracks in it. wouldn't matter if someone put a hole in the side of the tube, it would just get a little windy till it's patched.
@@beverlywhitman303 Yeah that's another idea. You don't need a complete vacuum, and you can also draw the air out in front of the train without creating a vacuum throughout the tube. But relying on the train alone to create a vacuum in front of it I'm not sure would work. You're basically carting a vacuum-making machine with you on every trip. That doesn't make sense.
@LordMightyTrousers Well not really pedantry. There's a big difference between the two technologies, they're pretty much opposites. Either the train makes the vacuum or the tube makes the vacuum. But at the moment it looks like designers worldwide are going with the vacuum tube, which makes sense, although it's a definite engineering challenge, no doubt about that.
@@beverlywhitman303 Although rereading your post some small amount of air recirculation device on the train in a non-hard vacuum does make sense so long as it's not a cumbersome addition to the train.
There’s a maglev in Shanghai running 430kph mainly because it’s just 30km long. However they just don’t run the speed part of the time due to the noise of the airflow. A train system either on tracks or a maglev would be a much better system. In regards of safety, price and feasibility it’s much better. Btw Virgin dropped half their team and said it couldn’t be used for passengers. However I like how you tried to mention the facts without bias
Just a thought, high speed trains in France have a commercial speed of 320km/h (although they can actually go over 500km/h but it's deemed unsafe).
So you'd make the trip between Dallas and Houston in roughly 1h15min. With a train that already exists, on regular tracks.
yeah its not a dumb idea but why do that when you can go from Dallas to Houston in 30min?? I see the point in that the tracks allready is built, but its not efficient compared to hyperloop, wich also is relatively cheep

"You can get from New York to L.A. in thirty seconds"
No... the pudding that used to be you, will get there in thirty seconds.
That was my thought.
certainly, the non stop acceleration, like sitting in a couple G's simulator, would not be a comfortable trip!
Although, they could put you in a fluid, and "depressurize" the fluid... if thats possible as fluid isn't exactly compressible; to reduce the sense of pressure you would experience as the fluid "compresses".... IDK. Just ideas.
Actually, it would be the fluid compressing the air in your body.. so create a vacuum outside of the fluid, to maintain the internal pressure your body experiences.
Something I never thought about... Could you leverage fluid dynamics to reduce the effect of G's on the human body? maybe increasing the surface area so there is less pressure per square inch, so the tank absorbs more of the pressure!
But... Were talking about inertia... so you're body is still gonna experience a flattening of itself internally, even if the surrounding is designed to accommodate non-pressure points... hmmmm...
Yea, my first question was, how do you survive the acceleration?
About ten seconds to speed up, then 20 to show down but that mass of bones and meat juice is not going to be happy about it.
@@AB-wf8ek You don't. Assuming constant acceleration and deceleration over the 2460 mile great circle route between New York Laguardia and LAX, and ignoring centrifugal forces, the acceleration is 1793.6 times Earth's gravity to a speed of 263.9 km/s and back to 0. That speed is 23.6 times Earth's escape velocity.
Your bones will have collapsed under that acceleration.
Not wanting to do the calculation, I think the centrifugal acceleration trying to follow the curve of the Earth through a tunnel through the Sierra Nevada, the Rockies, the Appalachians, and other minor mountain ranges and hills is going to be fairly significant.
The biggest problem with Hyperloop has always been, and will always be, that any savings you get from travelling in a vacuum are going to be more than eaten up by the cost of creating and maintaining a vacuum. A scaling up of the old school vacuum tubes for cargo could be an interesting concept, especially since cargo isn't as sensitive to things like pressure changes, g-forces, or even basic comfort as humans are, so there would be a whole lot less in the lines of design constraints.

In the US? Trains don't make any sense.
High-speed trains are a little too slow and too expensive, so we only have a couple of transit corridors that would work. Land prices and labor prices are both very high, and because only a couple corridors could make a profit, we don't have the economies of scale to drive construction costs down.
Airports are a better solution to that problem, because they connect individual cities without needing tons of infrastructure.
Hyperloop makes sense in the US because it's faster than airplanes, so it has a market niche for people who absolutely need to get somewhere as fast as possible.

High speed rail is horribly inefficient for sparsely populated areas. There are perhaps two corridors in the entire US that would be economical. Even regular rail is terrible for passengers in most cases, and within metropolitan areas buses are better in most ways. Turns out using existing infrastructure is easier. The US isn’t Japan, China or Germany, all of which are several times denser. Most of Western Europe is considerably denser too.

Calculate the energy required to create a vacuum in a tube of that length and diameter and you will begin to see the folly of hyperloop.
Ya you can't expect wanna believers to think.
It's like saying ''calculate the cost and effectiveness of renewable energy and you'll see that coal is better''. Hyperloop is still a prototype so just wait and in a few years there are solutions for every problem
add on to that the energy needed to keep the vacuum, cycle the airlocks, etc and you know it's rubbish. Now work out what happens should someone put even a small hole into the tube. You know that in the USA, a tube above ground will be shot at.
@@eliasmok3261 "Hyperloop is still a prototype"
Nope. Unless you mean that silly test track?
" there are solutions for every problem"
Yes there are but the solutions for the hyperloop are not viable. Do the math.
The other folly is the passenger vehicle would have to be built to space craft standard to withstand vacuum environment. It would have to carry air supply and CO2 scrubber. And it would be a good idea for passengers to wear space suits for redundancy just like astronauts. Contrast with airline fuselages which do not need to withstand vacuum and use pressurized external air for passengers to breathe. HL really is a folly.
No need to share Thunderfoot videos with you, I heard his voice in this script loud and clear :)
Great clip, as always!
Same thinking I love thunderfoot
They both reached the same conclusion, ultimately coming down to its economic viability. It's unlikely that selling tickets is going to be able to the cover the costs of building and maintaining the system. The light at the end of the tunnel is when we ditch the impracticality of the vacuum tube and start to build maglev trains right here in America.
I had watched Thunderfoot's video on it before, and this was a fresh take for me. I got the same information without the seemingly condensing nature Thunderfoot brought (that's just how I perceived him) to the table. And that helps a lot.
Thunderfoot has a hate boner for Elon for some reason. His videos are riddled with serious errors, he didn't do even a basic research. So ignore everything he said and think for yourself instead.
For example I love how everyone just assumes it won't be economically viable, without doing any kind of calculation. The only calculation I saw is from Elon Musk and his engineers. They know how much it costs to build stuff, because they are in the business of building all kinds of stuff. According to them the original Hyperloop would have cost ten times less than California's new high-speed rail line. That was the benchmark. Even with significant cost overruns they would have beat it easily. And the new design with tunnels is probably cheaper, because a big part of the cost is just acquiring the necessary land.
@@andrasbiro3007 A big part of the cost of California's rail was mismanagement. That played into the cost overruns. So it might not be the best comparison, as not all of it was due to construction based purely on the design.
I can't watch anything hyperloop related without hearing thunderfoot's voice
He's been wrong about soooo many things...
@@RockitFX1 such as?
@@foggs In this video Joe also mentioned that misconception about vacuum. Like if you make a hole in a vacuum tube the whole section will be destroyed. The truth is the air will just pour into the tube through the hole the same way water will pour into a submarine if you make a hole in it. And by way to handle a vacuum, you just need to handle an atmosphere of pressure meanwhile submarines can handle tens atmospheres of pressure it is just a matter of design strength.
@@pawelzybulskij3367 would be interesting to see that simulated - various projectile sizes at different speeds fired at a vacuum tube. It must fail catastrophically at some point
@@pawelzybulskij3367
Actually, pressurized liquid and gas vessels do not pose the same thread. For a given pressure and volume, gas vessels contain much more energy (as fluids are not compressible), a rupturing gas tank can explode like a handgrenade, whereas a rupturing liquid tank releases a stream of liquid. That's why every pressurized vessel is being filled with liqued upon being pressure tested.
However, i too think, that Thunderf00ts arguments are not even close to being valid. I mean, just look at the ISS, it gets bombarded by tiny pices of metal, that travel multiple times the speed of a rife bullet and the structural hull is only Milimeters thick. If that's not enough, we build fucking gas tanks for cars that withstand 300 to 700 times the pressure difference that the Hyperloop would have. The only real downside to the whole concept (in terms of cargo transport) is to maitain the vacuum.
"Oh, it's garbage." I thought the video would end right there.
Definitely could have.
well that is the executive summary of the video
Yes, it could have been a much shorter video. And he left it to almost last to point out that its being irredeemably uneconomic.

@@garyedwards5345 Take away the vacuum tube and the pods and what you have is maglev trains - which is already well understood technology (though it could do with more cost refinement).

@SAMUEL NAUMETS Thunderfoot's video is the same thing - hot garbage.
The tank implosion video is basically misinformation, and the argument made is completely wrong at a really fundamental level.
The reason tanks implode like that is because they're only designed to hold pressure from the inside, like a balloon. They're not designed to hold a vacuum, so they don't have safe failure modes and look catastrophic.
The logic being used is like trying to push a rope and assuming you're the strongest person in the world because it bent.
Vacuum pressure is not that hard of a design problem, pretty much any underwater tunnel is much harder to build.

@@hifijohn Worse than the Concorde. The Concorde _was_ built, it worked technically, and flew commercially for 27 years. I'm pretty certain that no commercial HyperLoop will ever be built, there are too many technical and financial obstacles before we even get to face the insurmountable economical, safety & maintenance problems.
There are technical questions about hyperloop that no one ever discusses: 1) What are the passengers going to breathe? They could breathe oxygen from bottles that someone has fill each trip. CO2 buildup will require a scavenging system (that has to be maintained frequently) 2) How are they going to cool the pod? Air conditioners have to reject the heat somewhere, normally by blowing air over the condenser. Can't do that in a vacuum. 3) Airplanes operating at high altitudes are required to have a back up oxygen supply (masks that drop out of the overhead)- won't the regulators require the same for pods traveling in a vacuum? That's a minor issue, but airliners are also required to have a stewardess to explain how to use the emergency oxygen... and point out the emergency exits... 4) Where are the emergency exits in the 300 mile long vacuum tube? There are other technical and regulatory issues, but those four are enough to scuttle hyperloop. The maglev train in Shanghai is great, but it's so expensive to operate that China only runs it at full speed twice a day. They have scaled back their plans for a large maglev network and will use wheeled high speed trains over most of the planned maglev routes.
The oxygen supply from the masks on a plane is just a chemical reaction that only lasts like 12 minutes or so. It’s sodium chloride, potassium something, and something else. No idea if that would be required for a hyper loop like system but it would be negligible to add.

There was a guy who worked for Strawbridge and Clothier in Philadelphia as a maintenance man who took his 15 minute breaks in a closet. Long after he retired they were doing some work and someone discovered that in the closet, a pneumatic tube ran through the closet and that there was a gate installed in the tube that could be easily opened. It was never proved but it was thought that this maintenance man spent his break period interrupting the cash from the checkout counters and skimming a little. Apparently he was smart, in that he never took so much as to cause suspicion. The word was he retired after 30 years and lived a life that was way above his station and had passed away by the time they discovered the glitch in their pneumatic system.

@@kentarouification and very very sweet, because the brain tastes like cotton candy.
For hyperloop to work, the trains have to also work without a vacuum. Of course, this would be at reduced efficiency, but if the entire train can be disabled by even a section being depressurized we have big issues. Maybe the sections of rail have doors every now and then that can close to prevent mass depressurization, or open to allow air into a section if an issue arises for a train.
The animation you show around 6:05 is misleading, because it actually shows a magnetic levitation system instead of a pneumatic one. The arrows indicate a Halbach array configuration.
I think he's right on the money with these hyperloop concepts being mainly used for cargo in the beginning. As far as I've seen, a lot of the earliest trains were really only used for industrial transport of goods, and in in cases that I've seen in The UK, the workers would ride along and actually help operate the brakes on the cars carrying the goods they'd harvested/produced on their commutes home every day.

I interviewed with Virgin... got a feeling there's a lot of "HYPE" in "Hyperloop".
Why does a Hyperloop have to be so limited in speed? If you can evacuate a tunnel down to like 1% of atmospheric pressure, it's not that much more difficult to go to what they call "high vacuum." At a certain pressure (I think it's around a millionth of an atmosphere) not only would any hypothetical shockwaves be exceedingly wimpy, they can't actually be created at all because the gas molecules are too far apart to sustain waves. This also more or less truly eliminates all the aerodynamic drag and you can do it with straightforward turbo pumps.
Once you do that, there's no specific speed limit. In fact, the simplest and safest type of maglev (the passive Inductrak type using Halbach arrays) is very efficient at any speed, but actually gets *more* efficient at higher speeds. You could have a system capable of going multiple times faster than an airplane for most of its journey and which also just drops you right in downtown wherever.
The concerns around the expense and difficulty of obtaining land rights are real, but can be solved by tunneling. That's particularly appealing if the new system you're making is a quantum leap over the current best alternative of airplanes. Going a *bit* faster than an airliner may not be enticing enough to enough people to sustain a business. But you could charge much more than business class prices for something that is drastically faster. LA to NY in an hour and a half? Houston to Chicago in 45 minutes? That's gold and a lot of people would pay a lot to be able to do that.
Basically, I'm not convinced that any of these companies have done serious unbiased customer research. It's a great idea technically, but the burden of proof is on them to show it could pan out economically. I'm just suggesting an alternative whose economics might work out better...

MARTY WE GOTTA STOP THEM FROM COMMENTING BEFORE THE VIDEO IS RELEASED!!
They're probably answerphiles.
You can upload videos on youtube as public, private and unlisted.
unlisted videos can still be watched using the direct link, but do not show up in the sub-box.
UA-camrs upload a video and then enter their release-time where it's supposed to show up in the inbox. But when you're a Patreon, it's quite common for channels to give you early-access to videos.. that's basically that.
The moment they upload the video, any patreon sponsor gets the link to the video, whether it's released or not. They can also comment on it.
Then the video is published and the timestamp of release is added to the video.
Screaming in terror is only necessary if you lack the knowledge to understand what is going on. Knowledge always beats fear.

“Just give me a high-speed maglev system.” I totally agree with you on that. We already have the technology to go 300 mph+ on a train today. The cost and complexity and safety issues to put a maglev train in a near vacuum tube to get an extra 200 - 300 mph isn’t worth it. Need to go faster than 300 mph? We’ve got airplanes for that.
If we could build an infrastructure with today’s BEST maglev train tech, and pay $45 for a ticket to go from Dallas to Houston in 45 minutes, I call that a win.
The problem with the train from Dallas to Houston is once you get there, you need a car so it seems like it defeats the purpose.
Maglev isn’t very practical either. The Shanghai maglev, for instance, loses like $80 million a year.
Wheel is easy, wheel is cheap, wheel is reliable, wheel is probably here to stay.
But airplanes destroy the planet and is not as efficiant and cheap as hyperloop..
@@edvardbookbratbak5473 Seeing as how there are precisely zero real world examples of a functional “hyperloop,” you have no basis for a cost comparison, Musk’s ridiculous claims of a vacuum sealed maglev system somehow magically being 10x cheaper than a traditional subway system notwithstanding. Until proven otherwise, the “hyperloop” is in the realm of vapourware/fantasy/low realism sci-fi, not reality.

i like your expression 'getting shrink wrapped in steel'. the real acceleration one can experience if you open the tube behind the train: you'll be mince meat!
energy wise it might be cheaper if you give every passenger his own 737. i was maintaining an electron beam welder of about 0.25 m/3 vacuum content and the effort to evacuate this little volume was amazing.
I like so much how you dig into the world's pile of info and put out truth,good job Joe

slight correction there Joe, Rail guns absolutely exist, they fire hypersonic projectiles. They just arent in general service yet.
One of the joys of train travel is being able to look out of the window. Even if the hyperloop actually worked, it would be a very boring way to travel.
Why? Put on the headset, follow the train from above in 3d with a narration from Leonard Nimoy talking about the plants and animals, even the history of the area. The future is what you make of it.

@@bobthesnowdog9972 why should he? There are just a few points he would not agree to. thunderf00t just see no uncertainty regarding the economics and safety of hyperloop. Joe just did not destroy hyperloop. thats all.
Here's my thought on Boring Co. - Coordinated autonomous electric vehicles in a one-way tunnel can all be moving the same speed. Fans at either end of a route can force air through the tunnel at the same speed as the vehicles. There you got it: no wind resistance, increased speed, greatly improved performance and ventilated tunnels.
I like the concept. Don't take the air away, but don't fight the air either. Take the air with you. 5 stars!!
"solid" stone isn't actually very solid at all in most areas, and it's saturated with groundwater, it will be interesting to see how they might stabilize the stone enough to hold a vacuum without flooding.
If they wanted to do an underground hyperloop, they would likely still need to line the tunnels with metal. It would be basically the same thing as the above ground version, just with more reinforcement from the ground outside it, less temperature variation, and less chance of impact breakage. On the flipside, any damage that did happen to part of the tube would be harder to repair and would need to be done from the inside. It'd still be impractical, just a bit less so.
Concrete with a moisture barrier.
Ever heard of shotcrete?
Perhaps they could add a "hypercooler" to just freeze all the water solid
Once you have the vacuum in the tube, you could then vacuum sputter the walls with Niobium to make the walls super conducting so that the train can be held up by the London Effect.
@@timogul Like I mentioned earlier, there are moisture barriers you can use no problem.
But an underground hyperloop wouldn't be very likely due to access concerns. The tunnels would need to be so well-sealed that they would be difficult to access if there's a malfunction. Having it aboveground makes it significantly safer, because you can disconnect a section to access it.

I don't like thunderf00t much. I think he's arrogant. (Come at me bro). But he's correct here. Almost everybody has ditched every novel idea in the white paper and everybody is back to the age-old "train in vacuum tube" idea. Yeah, also people do underestimate how difficult it is to create and maintain a vacuum on earth.
One very cool thing about the Beech train in NYC was that he built the thing right in the middle of the city, in secret. The tunnel was dug out under the existing streets & buildings; it stretched a block or two, & they did nearly all the work at night & snuck the dirt out in secret. Beech ran it underneath the offices of his major competitor.
"Hyperloop"... One thing that'll never happen.
next on pointless technology... vacuum balloons.
Maybe not as a measure of transportation here on earth. But if we make a long tube, put a capsule on something like a sledge in it and bend one end upwards in a smooth curve, we might end up with an efficient way to get stuff into near earh orbits.
Reusable rockets, electric cars, digging tunnels under cities, putting chips in peoples heads, and Autonomous cars. Other things that will never happen.
@@davidbeppler3032 except people haven't been saying those things will never happen for a long time already. And the concept of the vacuum train has existed for how many centuries? And it still is not working, properly and safely. Those other things you mentioned were realised in a reasonable time frame after they were first proposed and tried.
So stop thinking by analogy. Simply because in some cases peoplewere skeptical, but the concept worked does NOT mean every concept people are skeptical about will necessarily work. Or, by this "logic", "solar roadways" would work too 😂
@@KateeAngel How many vacuum trains have they built? I am unaware of any serious attempts yet. For it to fail, it has to be attempted first. Trains are not safe?

Got that right. I lived in Midland in the mid-Eighties. It's a real city, though ol course a small one. Nice for most things, but if you ever need something from a big city, the nearest one is at least about 300 miles away. Of course, when I lived there, "I can't drive…55!" had real meaning.

"They want to transport vast amounts of good and people over the Hyperloop. And again, the Hyperloop is not something that you just dump something on. It's not a big truck. It's a series of tubes."
~Sen. Ted Stevens, on the Hyperloop project
Where did Sen. Ted Stevens get his engineering degree?
My point is Ted is not a reliable source.
Here is an idea, park a segment of tube at a shipping dock, load it like any other trailer that goes on a truck using PIE, launch it down the tube to it's destination. Save billions of dollars in shipping costs. Put thousands of OTR out of work faster than FSD semis.
I thought the internet was a series of tubes?
Maybe the government just likes tubes too much.
@@Gameboygenius Sorry I missed the sarcasm. I am unfamiliar with who that Senator is.
I think you miss the economics of a constantly available transport vs. airplanes. You find out when your connection from Pittsburgh to Seattle is showing up and 2 an hour. You pick a pod and buy a ticket, show up, get on, and you are gone. You don't need all the logistics of a plane or airport. Just look how constant flow train systems work. You could easily got to Chicago to Pittsburgh back to Chicago on the same day having a choice of three stops in Chicago or Pittsburgh.
The air recirculation under the "car" , sort of ends the Vacuum concept.
The vacuum concept has ended the recirculation under the car concept.
to be fair Elons concept was for a pressurized tube that had big blowers blowing the air at supersonic speeds inside a big loop.
Honestly makes a lot more sense than a vacuum tube as you don't have to worry about a pressure build up in front of the train unlike in a vac tube (unless it's hard vacuum but they aren't doing that). nor do you have to worry about the train braking the sound barrier inside the tube as all the air is traveling the same speed as the train.
Mag-lev is still way better than his 'air barrings' though. but what i don't get is why they all dropped the "pushing the air inside the tube" bit to make the train go faster. we can make wind tunnels that have air flows over 5000 KPH, just think of making a wind tunnel in a big loop with rail tracks in it. wouldn't matter if someone put a hole in the side of the tube, it would just get a little windy till it's patched.
@@beverlywhitman303 Yeah that's another idea. You don't need a complete vacuum, and you can also draw the air out in front of the train without creating a vacuum throughout the tube. But relying on the train alone to create a vacuum in front of it I'm not sure would work. You're basically carting a vacuum-making machine with you on every trip. That doesn't make sense.
@LordMightyTrousers Well not really pedantry. There's a big difference between the two technologies, they're pretty much opposites. Either the train makes the vacuum or the tube makes the vacuum. But at the moment it looks like designers worldwide are going with the vacuum tube, which makes sense, although it's a definite engineering challenge, no doubt about that.
@@beverlywhitman303 Although rereading your post some small amount of air recirculation device on the train in a non-hard vacuum does make sense so long as it's not a cumbersome addition to the train.
Any plans how to get the people out of the vacuum tube in the case of emergency (of any kind)?

Dude, where did you get Dutch form paper? 😂
well spotted
There’s a maglev in Shanghai running 430kph mainly because it’s just 30km long. However they just don’t run the speed part of the time due to the noise of the airflow. A train system either on tracks or a maglev would be a much better system. In regards of safety, price and feasibility it’s much better. Btw Virgin dropped half their team and said it couldn’t be used for passengers.
However I like how you tried to mention the facts without bias
