Somebody who works on a particle accelerator here to also dunk on Hyperloop; do you know how difficult it actually is to pump down a small section of tubing to high vacuum and the kind of equipment needed and the energy requirements? Yeah, that on a human scale is stupidly inefficient compared to just using a regular train
Yeah. There are better ways to achieve speed. This is a really dumb question. Wonder if there is a way for trains to use something similar to those torpedoes that use super cavitation to create a bubble of air ahead moving the more turbulent air aside or some shit like that.
Things like 'Hyperloop' are what we, in the transport industry, would call a 'Gadgetbahn'. A new and complex mode of transit that seems futuristic, and tends to generate alot of excitement because of its futuristic, complex 'high-tech' look and feel . . . But is actually less workable, less effecient and less capable at what it's designed to do than older, simpler and existing technologies.
A gadgetbahn is probably the correct term to describe Indonesia's upcoming high-speed rail that'll connect Jakarta and Bandung, due to these factors: 1. It's ridiculously expensive, currently setting the nation back at an equal of US$ 8 billion; the same amount of money can be used to connect the whole of Indonesia on rails instead of only connecting the metropolitan cities of Jakarta and Bandung 2. It's not as efficient as the existing rail network between the cities, as the new HSR requires a new station that's less strategically located than the existing rail network at one end and doesn't really reach the city core of Bandung at the other end, requiring passengers to take a feeder train 3. The cities of Jakarta and Bandung are already super well-connected with the existing diesel trains or a myriad of shuttle buses, all of which have really affordable tickets. The new high-speed rail's expected ticket price is triple of these transports' ticket prices.

I flew on an Aeroflot passenger jet in 1983 from Moscow to Leningrad. There were people on board with live chickens in baskets. The plane creaked very audibly throughout the flight. I felt lucky to survive the flight.
@@hannahp1108 Many, many, many did. The list of Aeroflot crashes is like 5 wikipedia pages, and I'd say that alcohol was involved in at least a quarter, maybe even over a half.
@@belacickekl7579 Yes, it must be said there were not a single successful Aeroflot flight and 3 out every 2 flights end up crashing with over 10000 fatalities per a flight.
The pneumatic subway drawing/schematic you show on Broadway was the one created by Alfred Beach in the late 1800s. He couldn't get a permit from the city of New York (as his competition was thinking of running for mayor and bribed council to not approve Beach's plan) so Alfred dug the tunnel and two stations by hand, at night, in the dark over the course of a year. He then stuck a train in it and showed that pneumatics would work...but he and his invention were buried in political controversy. Beach's memory was immortalized in Canadian band Klaatu's song "Sub Rosa Subway' in 1973.
The Hyperloop always felt like Mel Brook's "The Producers": Something designed to fail because the people behind it found a way to make money off that failure.
What I’ve heard is that Hyperloop was intended to be a distraction from building California High-Speed Rail, which would have a decent chance at getting people out of their cars, so fewer future Tesla EV sales.
Elmo hates trains and accessibility. He used his PR-inflated but baseless reputation to plock funding for actual trains for this crap. And his idiot cultists eat it up lol.

I'm not an engineer. But I once had one tell me that one of the universal truths of engineering is that EVERYTHING leaks, even without the massive pressure differential required for the Hyperloop.
In the Hyperloop’s case it’s also an issue with the pod itself. Remember, the tube is pumped down to a vacuum. If a pod springs a leak, the air inside the pod will escape into the tube and all the passengers will die just as if they were dumped into the vacuum of space without a suit.
Your instincts serve you well. You're exactly right about that; NOthing is perfect. Perfection is an illusion, a goal that we strive for, but never totally achieve.
@@michaelimbesi2314 , thank you! 👍 That's what I'm always saying too. There's this one NASA story about a guy that was exposed to a hard vacuum for about 45 seconds. He was lucky to survive. If you look at the studies of regular train stations, they have to be about 15 MINUTES apart for the system to be economical. Too many stops, it's too expensive to run. Too little stops and people won't use it. I feel confident in saying that NObody can survive 15 minutes in a hard vacuum!
@@geelee1977 , I'm only an electronics engineer, so at first I was one of the minions that thought it was a good idea. But whenever I criticized some aspect of the project in social media its supporters would always attack me as some kind of "troll" 🙄. I just asked basic science questions like, "how much energy and TIME does it take to transport people through airlocks?" Or I'd ask, "what happens in the event that a pod LEAKS"? They want pretend that everything is perfect, and STAYS perfect over continuous long-term use by the public. No seal is perfect, or stays perfect forever. I guess I'll always be that "troll" that doesn't trust what rich billionaires want people to believe. I believe in Science instead!
I agree with you about the absurd Gulf monarchies. But I’ve been to Qatar and Oman, and Oman is totally different, in a good way. Just compare the skylines of Dubai and Muscat and you’ll see what I mean. It’s not perfect of course, but they have done a lot of things right in contrast to the other Gulf states. An episode on Oman would be very interesting.
I lived in Qatar, my parents went to Oman after. They gave very much the same impression, that Oman was a much saner place. Not that Qatar is like Dubai, but boy did they make some weird decisions "We're attaching 5 massive hotels to one mall" "Why?" "Shut up!" "Where will people park?" "They can park in the mall" "You mean the mall that doesn't have anywhere near enough parking when it's just being a mall?" "Shut up!"
@@nintendoeats I love and hate that this is a seemingly universal thing (building with no thought for parking). My tiny hometown in rural Ireland got rid of much of the already scant parking along the single street where all the local shops are recently, in order to widen the pavements so that they could put benches... in the middle of the town where no one has ever stopped to sit... so we can breathe in some car fumes??? and look at... the butcher shop window? The Post Office? Very bizarre.
@@RealElongatedMuskratmaybe they want you to start walking a bit more. Where I live the inner city isn't very suitable to cars due to it being very old. The local facebook group is so full of complaints about how there is no parking that it's become a meme among my friends. Meanwhile, if you walk five minutes north there is a football field of a parking lot that costs practically nothing, and south there is too. Just park your car and walk in the city and we will all have a better time.
Over the last few months Simon has shifted tone quite markedly, and while I can speculate whether it is part of a pub bet, a long planned strategy, a recent epiphany or something far cleverer that for me to comprehend, I don’t mind - I’m here for it 😂

@@roncolemanlaw he said something about being under the weather in a video released on another channel today, I know his filming schedule isn't linear in any way, but he films a lot in a day, this may have been produced in say, the same work week maybe? He sounds similarly stuffed up, but not quite so bad in this one. I feel for the guy, he's a freaking legend and just keeps on keeping on, under the weather or not. 😎
The TU-104 was also back heavy and had the tendency to pitch up violently and stall. The plane was developed from a piston engine bomber from Tupolev and was changed minimally for the first jet from Russia.
I think you have mistaken it with Tu-114 developed from Tu-95 turboprop bomber. (Mustard have great video about it). Tu-104 looks more like civilian variant of Tu-16 which is turbojet bomber.
The accident in 1981 was caused by overloading. The General Staff demand the cargo be put onboard. The general attitude by staff was pilots are just buss drivers.
7:55 “There has not been a single fatality due to accident of a US airline passenger in 14 years” Wrong, Southwest Flight 1380 had 1 fatality in 2018. An engine exploded, sending shrapnel into the cabin and causing a rapid decompression. One passenger was partially sucked out of the plane and died due to injuries
The stat may not have been quoted exactly correctly. Usually it's "there hasn't been a fatal CRASH of a US airliner since..." The Southwest flight didn't crash, so it doesn't get counted. But it's not correct to say there have been no fatalities at all.
been getting your videos recommended to me for a while and this is the one that made me subscribe. any channel that will ask "why would anyone want that?" before launching into a detailed explanation of "how did engineers turn this rich moron's fever dream into a shabby reality?" is probably worth hearing from regularly
Big question: despite this being technically impossible, how come so many people bought it, including politicians ? Don't these guys have hordes of consultants or something ?
My biggest safety concern with the hyperloop is decompression of the car itself. A small leak could result in suffocation of the passengers within minutes. Possibly even a condition similar to the bends which divers need to avoid.
They could use air masks connected to an oxygen line that drop down like on an airplane! Of course, if you need to put oxygen tanks on every car, then you’d be accelerating oxygen tanks around at extreme speeds in enclosed spaces… it’s a dangerous idea no matter what you do.
@@ethanjames8371 Even at the highest altitudes achieved by airliners, the exterior pressure is still around 0.1Atm, Hyperloop is supposed to run in 0.001Atm, nothing designed for aircraft use is suitable for such a low pressure!
Concerning the abandoned island projects: There's also the idea that extending your coastline by creating artificial islands would extend your Economic Exclusion Zone. Which is the same theory behind China creating artificial islands in the Indochina/South China/Vietnam Sea.
My favourite thing about that Economic Exclusion Zone theory is that it would require the neighbouring countries to not just go "No, that is our fishing and trade area"
@A L Quoting the Preamble to the United Nations Convention on The Law of The Sea, Article60; Artificial islands, installations and structures in the exclusive economic zone, Section 8: "Artificial islands, installations and structures do not possess the status of islands. They have no territorial sea of their own, and their presence does not affect the delimitation of the territorial sea, the exclusive economic zone or the continental shelf." So yeah it "was" a working theory of international law, but it is by *no* means a part of current international law. The UN ruled on the mater several times starting in 1982, and it was widely accepted under international law by the late 90's early 2000's. The timing of which might be taken as another possible reason for the growing lack of interest.
@@AL-lh2ht Artificial islands don't count, otherwise this would be widespread and leading to all kinds of conflicts CONSTANTLY. China is just claiming unclaimed or disputed already existing natural islands and reefs, building them up, then claiming it's China territory.
I loved the Space Shuttle. Had a toy from a very young age, always admired it...but to have a worse safety record than IT, as an airliner...is shocking!
The stupid Russian plane was still way safer than the Space Shuttle. This video has it wrong. The Shuttle flew a total of 135 times, and there were five of them that flew. That's not a lot of flights per vehicle. The Russian death machines obviously flew way, way more. It's like crashing your car once when you're a taxi driver, or crashing your car once, when you only drive it on your birthdays.
@@VideoDotGoogleDotCom That plane was a huge pile of garbage. Totally unstable and barely flyable. If you want a great USSR plane of the same era, then TU-114 is your friend. But TU-104....brrrrr
I watched a video about the TU-104 that crashed on takeoff and killed all of those high ranking military members. It said that part of the problem was the cargo. The officers bought a lot of stuff to take home like appliances and stuff and they basically forced the crew to get everything on board and it ended up being overweight with poor weight distribution and cargo not properly restrained
I stayed at Palm 🌴 jameriah in 2017 and I loved it! However what is shown here is mostly correct - Most greenery you can enjoy are the lone date and palm trees every 10 ft apart 😅 Then take into account the villas which are lovely, but I was on the outermost top left "branch" and it took the best part of 1 hour to reach Dubai itself and the mainland! 😂 - Such was the Palava! Depends on time of day and traffic, but even if you are close to the mainland it takes longer than May think 🤦🏻♂️
A sudden catastrophic loss in pressure in one section of a hyperloop would mean that even if the pods are stationary.. there is air coming at you, at the speed of sound. Now imagine the pod going at speed, it would be like hitting a brickwall.
Lived and worked in Dubai, hated every minute of it. From slave Labour, hypocritical alcohol laws, plastic covered rubbish buildings. Concrete made from sea sand, visibly continuously rusting rebar. Etc etc.
I would ask you to compare the safety record of the Comet against other early jets and Ithink you'll find that it co pares more than favourably. Apart from a few crashes in the very early days of the Comet, due to lack of knowledge of the process of fatigue around the windows, the plane had great record for safety. The lessons learned from the Comet were used in aircraft constructed since then.
Wasn’t the square windows the only real problem with the comet? It’s the only design issue that comes to mind when the comet is mentioned… if there were other problems I’d love to hear of them
Unfortunately it's safety was forever tarnished in the mind of the public. People were still quite scared of air travel even in a safe aircraft. So one that had a reputation of exploding mid air even if the issue is fixed is a hard sell. And along came the 707 and ended the British aviation industry so to speak. By being the first they also were the first to learn that vital lesson on metal fatigue, pressurization and square edges... someone was going to learn that lesson. If the 707 had come first with square windows and the Comet began with round windows perhaps Boeing would have gone out of business and the Comet would have it's descendants still flying. Alternate history is fun to speculate.
@@zachsmith1676 Some issues with rivets too. Of the three lost 2 were due to windows one in a storm, where the airframe broke apart. This was fixed and the Comet 2 & 3 were moderately succesful flying until the end of the 70s. But no where near the early market dominance Comet "1" had.
Passenger service Hyperloop would be a great opportunity to experience a thrill of dying from cabin decompression at sea level, without the inconvenience of going into upper atmosphere or space. Each capsule would not only have to carry its own life support system, but in case of cabin integrity compromise the entire atmosphere would immediately evacuate into the vacuum of the surrounding tube - and unless the passengers managed to get into what would have to be for all intended and purposes a spacesuit, everyone's blood would quickly boil. And of course there would be no practical way of rescuing anyone for hours, if not days.
The Khalifa C city in Abu Dhabi sits up there too. Khalifa A was well developed and well built. Khalifa B (later Shakboot city) was okay. It took a while to really develop a feel and for shops etc to move in but at least there were villas... In-between them both is a massive desert. Just nothing there at all... well, not quite nothing. There are roads into the sand that end and are covered in sand. There are weird little poles or pipes sticking up all over. View it from the air and you discover an entire "city" is mapped out with the services and roads in place but they ran out of money before they could build anything. 15 years ago
Any Hyperloop close to a vacuum is a death trap. If there's a rupture anywhere along the tube, there's gonna be a huge rush to reach equilibrium. This will move any pods in the tube, regardless of what direction they're supposed to going, towards the hole at face melting speeds, turning your insides into outsides.
And a hyperloop pod going 700 mph that hits a partially-air-filled section, would experience massive G-forces from air braking. Also not good for the passengers' insides.
It's no more of an issue for the hyperloop than ot is for high speed rail. As long as you are accelerating at a safe pace, you can reach high speeds without problem.
Recently discovered your channels. Your personality is fun to watch making it easy to absorb information. Well done. "because of course, Soviet Union" 🤣
I seem to remember hearing (maybe on one of Simon's channels?) the senior Soviet military officers had violated regulations and overloaded the Tupolev with contraband cargo, shifting the plane's center of gravity and causing its fatal fall. Edit: Lol!
More than that. That crash was a massive deal. They had illegal alcohol, foods, several Senior officials had their wives on board, a few had their mistresses. They even grabbed a couple giant, multi ton rolls of paper for their base newspaper. The pilot refused to fly the aircraft, but the flag officers were so drunk, they didn't care, and threatened him if he didn't get them home. One officer got last second permission to stay so he could go visit his daughter. The immediate reaction to the crash was NATO sabotage. Then they came to the conclusion that this officer sabotaged it for some reason. The more you read about it, the crazier it gets.
Well, in defense of the Tupolev and its bad design, that was kinda irrelevant in that crash. They had so massively overloaded the plane with all of their illicit crap, that any plane wouldve crashed!
Don't you just hate it when a soup noodle comes blasting out of your nose? Thanks Simon. I was peacefully having my lunch watching this megaproject merriment when we came to the "World Islands" as soon as I saw them the visceral hilarity commenced. (Lmao and noodle out my nose!) Guess I should watch you after eating.
The neat part about having the tube out in the sunlight... The top of the tube would grow as it warmed, but the bottom would not. So you end up with the mother of all sun kinks in the middle of the desert. Oooops. Assuming you figure a way around that by reflecting light onto the bottom half of the tube...What happens in San Francisco if the end at LA is utterly immobilized? The station would have to move north 600 or more feet. You can see the issue here... Doors open and the station is 600-1000 feet from where you are. Then it is time to throw in the weeks and months needed to pull a vacuum on the line from LA to San Fran.... Will require a large number of pumping stations to make it less than 6 months. And as said: LOTS of power, that the state doesn't seem to have..
It's always fun to hear a youtuber carry on about how much they know more than the engineers that are responsible for designing a project, as if the engineers never thought about the many possible problems. Of course, I too don't think those projects would work... but I'm also not an engineer.
The main issue with any of these "megaprojects" is that people aren't unanimously on board with them... some people have to ride trains that still just have a freaking hole in the floor for a bathroom....fix those issues first elon...then maybe everyone would get "onboard" and with the massive amount of extra support, effort and money some of these highly ambitious projects might become reality...
The biggest problem with putting a tunnel system (especially a delicate vacuum system) underground, is that the ground is constantly moving and shifting. I mean, think of how much work the highways need. How are you going to do that if it's underground?
Aside from the vacuum element, It's a mystery which humanity will never solve. Unless we acknowledge the existence of thousands of miles of subway systems.
@@AtheistOrphan The Underground has constantly been expanded. Most runs through clay or was built by cut and cover. Ground movement doesn't stop tunnels being built, they just don't have to be airtight. Musk seems to ignore the pressure on the outside of the tube as well as the problem, to say the least, of maintaining air in the pods. One accident and the system would be expensive scrap.
Yeah in regards to the British De-Havilland Comet it should be kept in mind, the early comet crashes can be blamed on poor jetliner conversion training whereas the crashes of 1954 can not be blamed on the basic design of the De-Havilland Comet which was sound and De-Havilland knew about pressurisation It is more the fault of the wrong construction methods and the metal fatigue phenomenon that was not well understood in the 50s As it should be kept in mind until the British Comet, no one had built a jetliner before the comet so there was a lot that was not understood, the comet 1 used square with rounded corners not square windows
Just FYI, dutch roll isn't normally much of an issue when it comes to flight controls, and on most aircraft, it won't cause a rapid stall. Many aircraft have dutch roll modes that can be aggravated , but that and the spiral modes are (should be?) some of the less difficult to damp out, I believe. This is because on most aircraft, dutch roll has a very long period of oscillation compared to pitching modes.
This thing about the Burj Kalifa's plumbing has been making the rounds for years but after some digging turns out to be untrue. Unless some new better sourced stuff came out more recently. The footage of the trucks always shown is of trucks queuing to ship sewage out of less privileged developments which were built too quickly, on the cheap, and with zero thought for amenities. So yeah, very much still "Just Dubai".
Musky do a overpriced, poorly designed, not though out project that seems like someone tried to use Star Trek physics (see the channel The Science of Science fiction) in the real world? That'd never happen 😱
Looks like article links don't stick? Teslas are notorious for locking people in when they catch fire. Which feels like a backfire of a Musk feature given where and when he grew up
If you want a deeper dive on the Tu 104 that killed 16 Soviet Admirals, look up Paper Skies, he has a great video on the subject. As with many things USSR, it's a tragicomedy.
We have a lamsom tube in our hospital for sending stuff to the lab and all over the hospital - I assume that’s pneumatic?! Hahaha wrote this before I saw the photo of one 😅
It most likely is; but it’s much easier to maintain a smaller pneumatic transporter used to send smaller things like medical samples to a lab (within the same building). Banks use them to make multiple drive through stalls (they can send you a small capsule through a tube with the paperwork you need) if I remember correctly
In order to field a jet airliner in an extreme hurry, the Tupolev design bureau took the Tu-16 "Badger" strategic bomber, with it's aggressively swept wings and put a bigger, pressurized fuselage on it. The sweep of the wings made for a higher landing speed. There was also problems of weight and balance. Bombs don't move aound in flight until they dropped and don't have luggage. The elevators often lacked the authority to recover from an uncommanded steep pitch-up of the nose.
The Hyperloop: when someone thinks the monorail episode of the Simpsons should be a guide to the future and that the Shinkansen is too technologically simple.
Very true, but I can't help but wonder why, if he was so sold on the Hyperloop idea, he gave it away. It almost seems like he knew it wouldn't work, but wanted people to waste time and money on it anyway.
Multibillionaries don't have to be experts.....they just employ people that are. Elon is lucky, very lucky. Unfortunately for humanity, in him, we have a billionaire with the mind of a petulant teenager.
@@andy2950 So the content and execution of covid policies, content moderation policies, and interaction with intelligence agencies of social media are cochure and present nothing worth opposing? And since Egon above me asked: Multiple accounts quote those who have worked with Elon as describing him a highly intelligent sponge of information, he was and remains SpaceX's chief engineer and early fundraising included personally answering detailed technical questions about his rocket's performance in real time to technologically educated investors, and SpaceX and Tesla - his two most prominent companies - share the same philosophy of development, corporate architecture, and continuous multi tiered, long term development, reflecting the personal philosophy of the common element of Elon Musk. Also - do you honestly cotton that the chief executive and driver of the short, medium, and long term business plans of two companies that have successfully and fully disrupted two of the most expensive, politically connected, long established, and largely stagnant industries on the planet just happened to 'get lucky'? That sounds slightly unlikely.
Uh... Double Star by RAH was a novel and it was more about politics and how if a significant leader is poisoned/disabled, how a doppelganger could be used to take his place. Pneumatic tube travel was never a real part of the story that I recall, although it has been a few minutes since I read that particular book. Now the novel he wrote in 1982, Friday, did mention pneumatic tube travel and also included ballistic point to point Earth travel and the "Beanstalk" which was used to transport people from the Earth to the Moon via an 'elevator'.
Pneumatic tubes on a small scale are useful. My bank uses tubes to transfer documents and money between the drive-up stations and the main office. The large scale Hyperloop is so preposterous I don't see which it's even being mentioned.
The Hyperloop was suppose to be underground, from LA to New York. Don't get me wrong, it's still a terrible idea with earthquakes and the need for bulkheads that can drop instantaneously.
I'm gonna go the unpopular route and say something about Musk that isn't "He sucks". I don't think he cares. He doesn't care about revolutionizing trains. Nor internet, or anything else. Besides Twitter, and a couple smaller projects, everything he's done is for one purpose. Colonizing Mars. New reusable rockets, great for getting to Mars. Hyperloop, useless here, may work on a smaller scale on Mars. Starlink, not great internet here, but would connect many remote colonies on Mars. Tesla, revolutionized EV on Earth, and once developed fully, would be great on Mars where IC engines won't work. If you look at what he does as "Making money on Earth", it's stupid and makes no sense. When you take his "I want to die on Mars, just not on landing." quote at face value, a lot of his stuff makes far more sense. Though, I'm convinced his "Not a flamethrower" and purchase of Twitter were both just his way of shitposting.
Tesla didn't revolutionise EVs. They have good marketing. The cars do no more than the GM EV-1 from 1996, they just have an advantage that technology moved on from when that car was released. And importantly, Musk had nothing to do with the company starting up, he just bought an existing company and insisted he got called "founder" - he also managed to get billions in funding from the US government for his toy car project. And if you are spending all your money burning through the resources of one planet to colonise another, you are absolutely the last person that should be colonising another planet.
I suppose you miss the point of why Dubai has built and is building unproductive projects like the palm islands and Burj Khalifa, they were never intended to be productive but rather attract attention (and therefore tourism) and all these projects have served that purpose well.
Our son lives in Dubai on the palm and it is more amazing than described HOWEVER you are correct SIMON with the WORLD ISLANDS. They took fortunes in advanced from private enterprises and large corporations to own a specific country island then ran out of money and stopped building. Our son a d his family take their boat out to different ones for BBQs. Lol
@Cottonheaded Ninnymuggins I am not hater, i think he has done some nice jobs like with SpaceX, but most of the time he just wildly overpromises and has some dubious projects (like Tesla Bot). Not to mention he sank twitter
Sadly, at my July 2023 writing the Ocean Gate implosion is still in major focus. Elon had better learn from pressure issues so tragically demonstrated as five lives were snuffed out.
You don't need to keep it in a vacuum, you just need to keep the airflow in the direction of travel faster than the train. The idea is just to minimize drag.
Tu-104 carrying 19 million passengers? You can' really name it 'useless'. Horribly dangerous - yes, but it was build and was in service for quite a long time.

I was always baffled how anyone took Hyperloop seriously for a second. It seemed immediately obvious it couldn't work. How did so many people get taken in by it for so long??
Why does it have to be some wild ass science fair project of a concept? Why cant we auppose more practical ideas like, idk maybe a high speed railways system between near by large metropolis areas to far flung suburban towns? Or inbetween makor cities like NYC/Boston/Philly? Or Dallas/Ft Worth, etc? That seems a lit more useful and achievable than multi billion dollar bank teller pneumatic tubes?
Just a look through some of the planes Russia has designed or actually built over the years shows that they're completely bonkers. Completely utterly insane things that somehow defy physics by actually becoming airborne. Most of them not staying that way for long though.
"Vacuum trains for transporting male and other sundries", oh how times have changed. Its beyond my comprehension how Dubi pours energy into the sea for vanity . King Canute . Great channel.
So... If you take a Hyperloop pod, put wings and an engine on it, and launch it above most of the atmosphere you get an airplane. We've had them for a while.
Simply creating a vacuum from a space would not in itself cause the cars to move in the tube. Ironically there would need to be a inlet for positive pressure air to create higher pressure behind the car, which is sealed to the walls of the tube, creating a massive low pressure area in front of the car, causing the car to flow with the high pressure air toward the source of the vacuum An actual vacuum is a static state, “flow” is the movement of a fluid From an area of high pressure To and area of lower pressure. In this case the cars would be the definitive point between hi and Lo The ideas just sucks
The Bureau of Aircraft Accidents Archives lists Aeroflot as top for all-time fatalities, with 11,308 by comparison Air France is second among civil operators with 1,752. I think I might just catch a train ...... 🤔😮
But you've forgot to mention that Aeroflot was *the only* soviet operator that served all the aircraft types from the small planes like An-2 and helicopters Mi-2 to heavy airliners and frights. So it should be compared not to Air France alone, but to ALL French air companies COMBINED (including already non-existing). Just to remind, as of 2019 there were 660 enterprises in the air transport industry of France.
about 20+ years ago I regularly bought a popular science journal. "Hyperloop" was better thought about back thanm then all Elon or his companies added to that idea.
14:00 Huh, I'm surprised the answer wasn't "none whatsoever". A petrostate that subsidizes gasoline, having any kind of public transit at all? Colour me surprised! 🤣
It's like Adam Something's usual point of "just build a fucking train", but presented by Simon :D There's also one more practical issue, at least on a continent like Europe with fairly few mostly empty places. You need to build a fairly straight tube to achieve the speeds, and planning that would probably bumb into yet another village every 10 kilometers or so. If BER airport only needed to get rid of one and that postponed the project by a decade, take a guess how feasible this thing will be.
Somebody who works on a particle accelerator here to also dunk on Hyperloop; do you know how difficult it actually is to pump down a small section of tubing to high vacuum and the kind of equipment needed and the energy requirements? Yeah, that on a human scale is stupidly inefficient compared to just using a regular train
Anything they can do to waste money instead of actually just funding high speed rail infrastructure and rail in general 🙄
Yeah. There are better ways to achieve speed.
This is a really dumb question. Wonder if there is a way for trains to use something similar to those torpedoes that use super cavitation to create a bubble of air ahead moving the more turbulent air aside or some shit like that.
Exactly! It was always a waste of time and money and probably just a boondoggle for a massive tax write-off.

Things like 'Hyperloop' are what we, in the transport industry, would call a 'Gadgetbahn'. A new and complex mode of transit that seems futuristic, and tends to generate alot of excitement because of its futuristic, complex 'high-tech' look and feel . . .

A gadgetbahn is probably the correct term to describe Indonesia's upcoming high-speed rail that'll connect Jakarta and Bandung, due to these factors:
1. It's ridiculously expensive, currently setting the nation back at an equal of US$ 8 billion; the same amount of money can be used to connect the whole of Indonesia on rails instead of only connecting the metropolitan cities of Jakarta and Bandung
2. It's not as efficient as the existing rail network between the cities, as the new HSR requires a new station that's less strategically located than the existing rail network at one end and doesn't really reach the city core of Bandung at the other end, requiring passengers to take a feeder train
3. The cities of Jakarta and Bandung are already super well-connected with the existing diesel trains or a myriad of shuttle buses, all of which have really affordable tickets. The new high-speed rail's expected ticket price is triple of these transports' ticket prices.

The pneumatic subway drawing/schematic you show on Broadway was the one created by Alfred Beach in the late 1800s. He couldn't get a permit from the city of New York (as his competition was thinking of running for mayor and bribed council to not approve Beach's plan) so Alfred dug the tunnel and two stations by hand, at night, in the dark over the course of a year. He then stuck a train in it and showed that pneumatics would work...but he and his invention were buried in political controversy. Beach's memory was immortalized in Canadian band Klaatu's song "Sub Rosa Subway' in 1973.
Very believable great detail 👌

As someone who lives on the West Coast, the Hyperloop was always ridiculous to me because...earthquakes
The Hyperloop always felt like Mel Brook's "The Producers": Something designed to fail because the people behind it found a way to make money off that failure.
What I’ve heard is that Hyperloop was intended to be a distraction from building California High-Speed Rail, which would have a decent chance at getting people out of their cars, so fewer future Tesla EV sales.
This right here. Also, I think the distraction angle us very valid
Elmo hates trains and accessibility. He used his PR-inflated but baseless reputation to plock funding for actual trains for this crap. And his idiot cultists eat it up lol.

I'm not an engineer. But I once had one tell me that one of the universal truths of engineering is that EVERYTHING leaks, even without the massive pressure differential required for the Hyperloop.
In the Hyperloop’s case it’s also an issue with the pod itself. Remember, the tube is pumped down to a vacuum. If a pod springs a leak, the air inside the pod will escape into the tube and all the passengers will die just as if they were dumped into the vacuum of space without a suit.
I am an engineer, and the hyperloop is pure anti-science.
Your instincts serve you well. You're exactly right about that; NOthing is perfect. Perfection is an illusion, a goal that we strive for, but never totally achieve.
@@michaelimbesi2314 , thank you! 👍 That's what I'm always saying too. There's this one NASA story about a guy that was exposed to a hard vacuum for about 45 seconds. He was lucky to survive. If you look at the studies of regular train stations, they have to be about 15 MINUTES apart for the system to be economical. Too many stops, it's too expensive to run. Too little stops and people won't use it. I feel confident in saying that NObody can survive 15 minutes in a hard vacuum!
@@geelee1977 , I'm only an electronics engineer, so at first I was one of the minions that thought it was a good idea. But whenever I criticized some aspect of the project in social media its supporters would always attack me as some kind of "troll" 🙄.

They want pretend that everything is perfect, and STAYS perfect over continuous long-term use by the public. No seal is perfect, or stays perfect forever. I guess I'll always be that "troll" that doesn't trust what rich billionaires want people to believe. I believe in Science instead!
I agree with you about the absurd Gulf monarchies. But I’ve been to Qatar and Oman, and Oman is totally different, in a good way. Just compare the skylines of Dubai and Muscat and you’ll see what I mean. It’s not perfect of course, but they have done a lot of things right in contrast to the other Gulf states. An episode on Oman would be very interesting.
I lived in Qatar, my parents went to Oman after. They gave very much the same impression, that Oman was a much saner place. Not that Qatar is like Dubai, but boy did they make some weird decisions

7:55 “There has not been a single fatality due to accident of a US airline passenger in 14 years”
Wrong, Southwest Flight 1380 had 1 fatality in 2018. An engine exploded, sending shrapnel into the cabin and causing a rapid decompression. One passenger was partially sucked out of the plane and died due to injuries
I think I heard about this from Mr. Ballen here on TH-cam. The story about this incident was horrifying.
The stat may not have been quoted exactly correctly. Usually it's "there hasn't been a fatal CRASH of a US airliner since..." The Southwest flight didn't crash, so it doesn't get counted. But it's not correct to say there have been no fatalities at all.

As an HVAC tech who regularly puts lengths of piping under a vacuum I can definitely attest to how impossible this idea is
Big question: despite this being technically impossible, how come so many people bought it, including politicians ? Don't these guys have hordes of consultants or something ?
In Finland Tupolev is known as “Putolev” or (roughly translated) “drop-down-olev” 😅
That's gold!
Puto... that means gay/coward in spanish.
My biggest safety concern with the hyperloop is decompression of the car itself. A small leak could result in suffocation of the passengers within minutes. Possibly even a condition similar to the bends which divers need to avoid.
They could use air masks connected to an oxygen line that drop down like on an airplane!
Of course, if you need to put oxygen tanks on every car, then you’d be accelerating oxygen tanks around at extreme speeds in enclosed spaces… it’s a dangerous idea no matter what you do.

Concerning the abandoned island projects: There's also the idea that extending your coastline by creating artificial islands would extend your Economic Exclusion Zone. Which is the same theory behind China creating artificial islands in the Indochina/South China/Vietnam Sea.
It was more to increase the coastline so you can build beach front houses. which is the only use you would want in Dubia.
My favourite thing about that Economic Exclusion Zone theory is that it would require the neighbouring countries to not just go "No, that is our fishing and trade area"
@@sand0decker Its not a theory. Its international law.
@A L Quoting the Preamble to the United Nations Convention on The Law of The Sea, Article60;
Artificial islands, installations and structures in the exclusive economic zone, Section 8:
"Artificial islands, installations and structures do not possess the status of islands. They have no territorial sea of their own, and their presence does not affect the delimitation of the territorial sea, the exclusive economic zone or the continental shelf."
So yeah it "was" a working theory of international law, but it is by *no* means a part of current international law. The UN ruled on the mater several times starting in 1982, and it was widely accepted under international law by the late 90's early 2000's. The timing of which might be taken as another possible reason for the growing lack of interest.
@@AL-lh2ht Artificial islands don't count, otherwise this would be widespread and leading to all kinds of conflicts CONSTANTLY. China is just claiming unclaimed or disputed already existing natural islands and reefs, building them up, then claiming it's China territory.
Thunderfoot endlessly made fun of the hyperloop.
While the Hyperloop has problems, don't cite that dumbass if you want to indicate those problems.
I loved the Space Shuttle. Had a toy from a very young age, always admired it...but to have a worse safety record than IT, as an airliner...is shocking!
The stupid Russian plane was still way safer than the Space Shuttle. This video has it wrong. The Shuttle flew a total of 135 times, and there were five of them that flew. That's not a lot of flights per vehicle. The Russian death machines obviously flew way, way more. It's like crashing your car once when you're a taxi driver, or crashing your car once, when you only drive it on your birthdays.
@@VideoDotGoogleDotCom That plane was a huge pile of garbage. Totally unstable and barely flyable. If you want a great USSR plane of the same era, then TU-114 is your friend. But TU-104....brrrrr
I watched a video about the TU-104 that crashed on takeoff and killed all of those high ranking military members. It said that part of the problem was the cargo. The officers bought a lot of stuff to take home like appliances and stuff and they basically forced the crew to get everything on board and it ended up being overweight with poor weight distribution and cargo not properly restrained

I would ask you to compare the safety record of the Comet against other early jets and Ithink you'll find that it co pares more than favourably. Apart from a few crashes in the very early days of the Comet, due to lack of knowledge of the process of fatigue around the windows, the plane had great record for safety. The lessons learned from the Comet were used in aircraft constructed since then.
Wasn’t the square windows the only real problem with the comet? It’s the only design issue that comes to mind when the comet is mentioned… if there were other problems I’d love to hear of them
Unfortunately it's safety was forever tarnished in the mind of the public. People were still quite scared of air travel even in a safe aircraft. So one that had a reputation of exploding mid air even if the issue is fixed is a hard sell. And along came the 707 and ended the British aviation industry so to speak. By being the first they also were the first to learn that vital lesson on metal fatigue, pressurization and square edges... someone was going to learn that lesson. If the 707 had come first with square windows and the Comet began with round windows perhaps Boeing would have gone out of business and the Comet would have it's descendants still flying. Alternate history is fun to speculate.
@@zachsmith1676 Some issues with rivets too. Of the three lost 2 were due to windows one in a storm, where the airframe broke apart. This was fixed and the Comet 2 & 3 were moderately succesful flying until the end of the 70s. But no where near the early market dominance Comet "1" had.
Passenger service Hyperloop would be a great opportunity to experience a thrill of dying from cabin decompression at sea level, without the inconvenience of going into upper atmosphere or space. Each capsule would not only have to carry its own life support system, but in case of cabin integrity compromise the entire atmosphere would immediately evacuate into the vacuum of the surrounding tube - and unless the passengers managed to get into what would have to be for all intended and purposes a spacesuit, everyone's blood would quickly boil. And of course there would be no practical way of rescuing anyone for hours, if not days.
The Khalifa C city in Abu Dhabi sits up there too. Khalifa A was well developed and well built. Khalifa B (later Shakboot city) was okay. It took a while to really develop a feel and for shops etc to move in but at least there were villas... In-between them both is a massive desert. Just nothing there at all... well, not quite nothing. There are roads into the sand that end and are covered in sand. There are weird little poles or pipes sticking up all over. View it from the air and you discover an entire "city" is mapped out with the services and roads in place but they ran out of money before they could build anything. 15 years ago
Any Hyperloop close to a vacuum is a death trap. If there's a rupture anywhere along the tube, there's gonna be a huge rush to reach equilibrium. This will move any pods in the tube, regardless of what direction they're supposed to going, towards the hole at face melting speeds, turning your insides into outsides.
And a hyperloop pod going 700 mph that hits a partially-air-filled section, would experience massive G-forces from air braking. Also not good for the passengers' insides.
They would move away from the hole as thats were the air is rushing in from
A problem of the hyperloop for transporting any living beings is g forces in acceleration and particularly stopping.
It's no more of an issue for the hyperloop than ot is for high speed rail. As long as you are accelerating at a safe pace, you can reach high speeds without problem.
2 minutes are enough to speed up to 1000 km/h if you only accelerate as much as an average automobile does from 0 to 100 km/h.

I seem to remember hearing (maybe on one of Simon's channels?) the senior Soviet military officers had violated regulations and overloaded the Tupolev with contraband cargo, shifting the plane's center of gravity and causing its fatal fall.
Edit: Lol!
More than that. That crash was a massive deal. They had illegal alcohol, foods, several Senior officials had their wives on board, a few had their mistresses. They even grabbed a couple giant, multi ton rolls of paper for their base newspaper. The pilot refused to fly the aircraft, but the flag officers were so drunk, they didn't care, and threatened him if he didn't get them home. One officer got last second permission to stay so he could go visit his daughter. The immediate reaction to the crash was NATO sabotage. Then they came to the conclusion that this officer sabotaged it for some reason.
The more you read about it, the crazier it gets.
Well, in defense of the Tupolev and its bad design, that was kinda irrelevant in that crash. They had so massively overloaded the plane with all of their illicit crap, that any plane wouldve crashed!

The neat part about having the tube out in the sunlight... The top of the tube would grow as it warmed, but the bottom would not. So you end up with the mother of all sun kinks in the middle of the desert. Oooops. Assuming you figure a way around that by reflecting light onto the bottom half of the tube...What happens in San Francisco if the end at LA is utterly immobilized? The station would have to move north 600 or more feet. You can see the issue here... Doors open and the station is 600-1000 feet from where you are. Then it is time to throw in the weeks and months needed to pull a vacuum on the line from LA to San Fran.... Will require a large number of pumping stations to make it less than 6 months. And as said: LOTS of power, that the state doesn't seem to have..

The biggest problem with putting a tunnel system (especially a delicate vacuum system) underground, is that the ground is constantly moving and shifting. I mean, think of how much work the highways need. How are you going to do that if it's underground?
Aside from the vacuum element, It's a mystery which humanity will never solve.
Unless we acknowledge the existence of thousands of miles of subway systems.
Victorian engineers seemed to crack the latter with the London Underground system.
@@AtheistOrphan The Underground has constantly been expanded. Most runs through clay or was built by cut and cover. Ground movement doesn't stop tunnels being built, they just don't have to be airtight. Musk seems to ignore the pressure on the outside of the tube as well as the problem, to say the least, of maintaining air in the pods. One accident and the system would be expensive scrap.
“The only slight problem with all of these proposals is that, well, they’re all just a bit insane.”
Hyperloop sounds like the name of a new super fast amusement park loop coaster.
Yeah in regards to the British De-Havilland Comet it should be kept in mind, the early comet crashes can be blamed on poor jetliner conversion training whereas the crashes of 1954 can not be blamed on the basic design of the De-Havilland Comet which was sound and De-Havilland knew about pressurisation
It is more the fault of the wrong construction methods and the metal fatigue phenomenon that was not well understood in the 50s
As it should be kept in mind until the British Comet, no one had built a jetliner before the comet so there was a lot that was not understood,
the comet 1 used square with rounded corners not square windows
Just FYI, dutch roll isn't normally much of an issue when it comes to flight controls, and on most aircraft, it won't cause a rapid stall.
Many aircraft have dutch roll modes that can be aggravated , but that and the spiral modes are (should be?) some of the less difficult to damp out, I believe. This is because on most aircraft, dutch roll has a very long period of oscillation compared to pitching modes.

It most likely is; but it’s much easier to maintain a smaller pneumatic transporter used to send smaller things like medical samples to a lab (within the same building). Banks use them to make multiple drive through stalls (they can send you a small capsule through a tube with the paperwork you need) if I remember correctly

elon was really trying to make the futurama tubes 😔😔😔
I wouldn’t be surprised if that was the inspiration
In order to field a jet airliner in an extreme hurry, the Tupolev design bureau took the Tu-16 "Badger" strategic bomber, with it's aggressively swept wings and put a bigger, pressurized fuselage on it. The sweep of the wings made for a higher landing speed. There was also problems of weight and balance. Bombs don't move aound in flight until they dropped and don't have luggage. The elevators often lacked the authority to recover from an uncommanded steep pitch-up of the nose.

Also - do you honestly cotton that the chief executive and driver of the short, medium, and long term business plans of two companies that have successfully and fully disrupted two of the most expensive, politically connected, long established, and largely stagnant industries on the planet just happened to 'get lucky'? That sounds slightly unlikely.
Uh... Double Star by RAH was a novel and it was more about politics and how if a significant leader is poisoned/disabled, how a doppelganger could be used to take his place. Pneumatic tube travel was never a real part of the story that I recall, although it has been a few minutes since I read that particular book. Now the novel he wrote in 1982, Friday, did mention pneumatic tube travel and also included ballistic point to point Earth travel and the "Beanstalk" which was used to transport people from the Earth to the Moon via an 'elevator'.
There's nothing wrong with the Hyperloop idea that a lode of Vibranium and the best architects and engineers from Wakanda couldn't fix.
Nothing is crazy about looking into an old idea on occasion. Actually building it when all the problems are not yet solved would have been a bad idea.
Pneumatic tubes on a small scale are useful.
My bank uses tubes to transfer documents and money between the drive-up stations and the main office.
The large scale Hyperloop is so preposterous I don't see which it's even being mentioned.
I use hydraulics tubes to get rid of my poo.
The Hyperloop was suppose to be underground, from LA to New York. Don't get me wrong, it's still a terrible idea with earthquakes and the need for bulkheads that can drop instantaneously.
I'm gonna go the unpopular route and say something about Musk that isn't "He sucks".
I don't think he cares. He doesn't care about revolutionizing trains. Nor internet, or anything else. Besides Twitter, and a couple smaller projects, everything he's done is for one purpose. Colonizing Mars.
New reusable rockets, great for getting to Mars.
Hyperloop, useless here, may work on a smaller scale on Mars.
Starlink, not great internet here, but would connect many remote colonies on Mars.
Tesla, revolutionized EV on Earth, and once developed fully, would be great on Mars where IC engines won't work.
If you look at what he does as "Making money on Earth", it's stupid and makes no sense.
When you take his "I want to die on Mars, just not on landing." quote at face value, a lot of his stuff makes far more sense.
Though, I'm convinced his "Not a flamethrower" and purchase of Twitter were both just his way of shitposting.
lol
Surprisingly I actually think it's more unpopular to think he's not full of crap
Tesla didn't revolutionise EVs. They have good marketing. The cars do no more than the GM EV-1 from 1996, they just have an advantage that technology moved on from when that car was released. And importantly, Musk had nothing to do with the company starting up, he just bought an existing company and insisted he got called "founder" - he also managed to get billions in funding from the US government for his toy car project.
And if you are spending all your money burning through the resources of one planet to colonise another, you are absolutely the last person that should be colonising another planet.
You can still see some of the pump houses built by Brunel for his Atmospheric Railway in places like Starcross and Torquay, UK
When money is no object, sense is disabled
I suppose you miss the point of why Dubai has built and is building unproductive projects like the palm islands and Burj Khalifa, they were never intended to be productive but rather attract attention (and therefore tourism) and all these projects have served that purpose well.
Our son lives in Dubai on the palm and it is more amazing than described HOWEVER you are correct SIMON with the WORLD ISLANDS. They took fortunes in advanced from private enterprises and large corporations to own a specific country island then ran out of money and stopped building. Our son a d his family take their boat out to different ones for BBQs. Lol
This is the most hilarious posts of yours I've ever seen ! Thanks Simon !
Expecting lots od elon chads, defending their lord
@Cottonheaded Ninnymuggins I am not hater, i think he has done some nice jobs like with SpaceX, but most of the time he just wildly overpromises and has some dubious projects (like Tesla Bot). Not to mention he sank twitter
@Cottonheaded Ninnymuggins this is a really funny statement. Touch grass
You were unfortunately correct. Lot's of insecurity and projection showing up
@Cottonheaded Ninnymuggins it's not being a hater if someone recognizes reality instead of kissing the modern day PT Barnum's butt
Sadly, at my July 2023 writing the Ocean Gate implosion is still in major focus. Elon had better learn from pressure issues so tragically demonstrated as five lives were snuffed out.
Musk is a funny guy.
He decided electric cars in narrow tunnels was more profound than it sounds.
You don't need to keep it in a vacuum, you just need to keep the airflow in the direction of travel faster than the train. The idea is just to minimize drag.
We need the Tu-104 as the official jet of The US government.
You have been elected, lol!!
Tu-104 carrying 19 million passengers? You can' really name it 'useless'. Horribly dangerous - yes, but it was build and was in service for quite a long time.
Vacuum-tube interoffice mail served large US buildings. In a Warner Bros. cartoon, Daffy Duck sends a mouse this way to pester Porky Pig. See also 'Duck Dodgers in the 24th-&-a-half Cenfury!
I was always baffled how anyone took Hyperloop seriously for a second.
It seemed immediately obvious it couldn't work.
How did so many people get taken in by it for so long??
Kinda like wind and solar power were going to replace all the fossil fuels on the planet
Why does it have to be some wild ass science fair project of a concept? Why cant we auppose more practical ideas like, idk maybe a high speed railways system between near by large metropolis areas to far flung suburban towns? Or inbetween makor cities like NYC/Boston/Philly? Or Dallas/Ft Worth, etc? That seems a lit more useful and achievable than multi billion dollar bank teller pneumatic tubes?
Everyone always seems to overlook why Musk does things like Hyperloop and it's quite sad.
We can’t stop our oil pipelines from leaking and that’s oil, not under extreme pressure. How the hell you going to keep a hyper loop AIR tight?
Tu-104: I am the most useless soviet megaproject plane
Tu-144: Allow me to introduce myself
Just a look through some of the planes Russia has designed or actually built over the years shows that they're completely bonkers.
Completely utterly insane things that somehow defy physics by actually becoming airborne. Most of them not staying that way for long though.
"Vacuum trains for transporting male and other sundries", oh how times have changed. Its beyond my comprehension how Dubi pours energy into the sea for vanity . King Canute . Great channel.
Fantastic video. Hyperloop FTL!
So... If you take a Hyperloop pod, put wings and an engine on it, and launch it above most of the atmosphere you get an airplane. We've had them for a while.
Simply creating a vacuum from a space would not in itself cause the cars to move in the tube.
Ironically there would need to be a inlet for positive pressure air to create higher pressure behind the car, which is sealed to the walls of the tube, creating a massive low pressure area in front of the car, causing the car to flow with the high pressure air toward the source of the vacuum
An actual vacuum is a static state, “flow” is the movement of a fluid
From an area of high pressure
To and area of lower pressure.
In this case the cars would be the definitive point between hi and Lo
The ideas just sucks
Hospitals in the UK use nematic mail systems to sent samples to the labs.
Those trucks are carrying significantly more than the tonnage quoted
The Bureau of Aircraft Accidents Archives lists Aeroflot as top for all-time fatalities, with 11,308 by comparison Air France is second among civil operators with 1,752. I think I might just catch a train ...... 🤔😮
But you've forgot to mention that Aeroflot was *the only* soviet operator that served all the aircraft types from the small planes like An-2 and helicopters Mi-2 to heavy airliners and frights. So it should be compared not to Air France alone, but to ALL French air companies COMBINED (including already non-existing). Just to remind, as of 2019 there were 660 enterprises in the air transport industry of France.
about 20+ years ago I regularly bought a popular science journal. "Hyperloop" was better thought about back thanm then all Elon or his companies added to that idea.
Yes, the more I watch things like this, the less hope I have for humanity.
14:00 Huh, I'm surprised the answer wasn't "none whatsoever". A petrostate that subsidizes gasoline, having any kind of public transit at all? Colour me surprised! 🤣
It's like Adam Something's usual point of "just build a fucking train", but presented by Simon :D There's also one more practical issue, at least on a continent like Europe with fairly few mostly empty places. You need to build a fairly straight tube to achieve the speeds, and planning that would probably bumb into yet another village every 10 kilometers or so. If BER airport only needed to get rid of one and that postponed the project by a decade, take a guess how feasible this thing will be.
Am I the only one that pictured Rick Moranis saying "Prepare for ludacris speed."?
