Josh Giegel: Super speed, magnetic levitation and the vision behind the hyperloop | TED
HTML-код
- Опубликовано: 19 июн 2024
- What if your hour-long commute was reduced to just minutes? That's the promise of the hyperloop: a transit system designed around a pod that zooms through a vacuum-sealed space (roughly the size of a subway tunnel) at hyper-speed, powered by next-generation batteries and state-of-the-art magnetic levitation. In the visionary talk, Josh Giegel, the hyperloop's very first passenger, shares how this zipping innovation could launch us into a faster, cleaner future of transportation.

But the hyperloop was already debunked because of the following two reasons.
1. The cost to build and maintain a constant vaccum in a tube stretching cities would be an order of magnitude more expensive to operate than it would a high speed rail network than spanned the entire United States.
2. Repressurization due to a single fault or general wear and tear would be enough to kill everyone currently in the tube (do people actually know how violent vacuum repressurization is?)
I get that the US failed to build an actual decent passenger rail network, but that doesn't mean you need to jump the shark with this hyperloop nonsense. It's investment bait / snake oil, sorta reminds me of that Simpsons Monorail episode...but somehow more needlessly expensive and dangerous.
He did not say vaccum though. I totally agree, but details matter if we aim to stop this nonsense. How much air can you remove before the pressure makes the tube too dangerous? Is there a middle ground for this vaccum idea? Air density vs speed gain vs tube seal cost?
Not long time ago electric self-driving car was a nonsense too.... but one stubborn dude kept pushing the idea and by learning on own mistakes made extraordinary into reality. Nowadays when other cars manufacturers want similar technology they far behind Tesla with BIG DATA about it. You have to realize that only by building this new loop system we’d be able to get real data about what’s right with it and what needs to be modified. We are talking about learning absolutely new way of “roads”. It gives plenty of food for a thought for investors who live in the age of reusable self-landing ( self-reloading soon) space rockets. I find hard to see such people as charlatans like you see them.
@@vcat417 indeed, for all the high tech wonders we enjoy, there was a period when it was expensive, unwieldy, and unreliable all at the same time. I costs a ton to make an idea practical. But an honest and thorough analysis of the hyperloop, as per Thunderf00t, shows how little you get for moon-shot level efforts. It's not hard to decide that $10 billion is better spent on more sensible endeavors, like regular high-speed rail. I think you'd enjoy Thunderf00t's "high-tech debunking" videos. For real, check out his smack-down on atmospheric water machines!
@@exegetor I'm looking forward to Thunderfoots video on this!
@@vcat417 Tesla didn't invent the concept of self driving cars... They've been working on them since before Tesla existed as a company. Also, they aren't exactly in the lead, waymo is currently the only company in the US that has vehicles on the road that are completely autonomous / don't require any human attention. Cruise and a couple others a pretty good too. This comment is wild.
The Maglev Hyperloop what a great idea! maybe it can run on a freaking solar road! yay.
I just hope they have f00tlongs in their thunderous subways.
You negative Nancy! They reinvented the tunnel! On stilts!
Actually, that gives me an Idea: They could make a new company that focuses on that. Instead of some Boring name, they can call it "The Pipe-Dream Company".
Idea: Cup holders with dehumidifiers built-in that fill your cup while you ride the Hyperloop in comfort 6 feet underground. Give me the Nobel now.
Thunderoot punching the air rn
_"Just build a fucking train!"_
Just do trains. They work.
Too simple. No "wow" there, so no clicks. I can't believe someone actually thinks this will happen..
America can't build high speed train and they think they can build an hyperloop. This will be a disater...
I love this explanation… wait-
“We also need to invest in infrastructure.”
Politicians: “Aight, imma head out.”
Trains intended for unbuilt Milwaukee-Madison high-speed rail lines are now going to Nigeria lol.
IF they ever get a hyperloop system to work, it needs to be for transporting goods only. Not people. Free up the roads from trucks
They showed it working in the video and literally had 2 people in it smiling with how pleased the experience was. His entire airplane analogy kinda describes your exact fear. Even if it takes 80 more years to perfect its better than continuing down the same path of destruction were currently going down.
We actually have train infrastructure for a reason: great at transporting goods at a fraction of the cost
It's just another train, albeit way more destructive to itself when an accident happens. I can't see shipping companies wanting to put their faith in it.
@@bradleymarsh8583 they showed it going in a straight line at about 50kph or less. Check what happens when you try to turn. Thunderf00t has debunked this guy properly.
**COUGH**...**COUGH** like trains?
Right but. Trains man. Way more capacity, way more reliability, way cheaper.
And they can still be renewably powered. Lots of sun down in Vegas at least.
this guy is smarter than TED. Thank you, brave smart person.
@@illygah Actually he's a confidence trickster. Apparently 'dumbing down' worked and you can't see it.
If we had just invested in the Shinkansen here like the Japanese did, then we’d have fast electric trains 30 years ago.
I dunno but if this was so great other countries that already use trains much more would have one of these.
And there’s another solution for human contact that takes zero time, is free, has no environmental impact, is boundless and available already .. video meets. hard to compete with that.
Will it go from city to Mars-spaceport? And will it be Tesla Semi-accessible? Maybe via Solar Roadways? Surely this is solar-powered, produces more energy than it consumes, better than the laws of physics AND the safest form of travel since the INSANE NEW Starship 2.0(!)?
If only he had listened to his wife.
🤣
In a hyperloop you'll be able to go from New York to Heaven in 10 seconds flat.
@@bracholi Oh yes. So flat... 😁
@@SchlangeVonEden I find it still amazing that there are people who believe in the promise to travel half around the world in half an hour with starship. I did some rough calculations and ended up at a permanent acceleration&deceleration of 20g. a nuclear warhead doesn't care, I'm not so sure about the human body.
@@bracholi Possibly quicker.
Explosive decompression, anyone? Nah, it'll never build up enough of a vacuum to get more than an inward "puff".
And as the air rushes in at the speed of sound, forcing the pod through the tunnel with explosive speed gasses like a bullet through the chamber of a gun, ultimately firing it into/through the end of the tunnel.
The tunnels are thin, and yet have to support a moving pod, the expansion/contraction of the metals in weather, and possibly the movement of the tectonic plates over fault lines. Even the tank of a gas truck can crumple like a soda can if left out in the hot sun, and then doused with cool water while sealed (the air inside contracts). Mythbusters showed it on camera over a decade ago.
I'm not so sure about the loop, but yes it is a hype.
why pods? i guess i can imagine if the pods were really long, a lot of air could build up at the front and cause significant drag? whatever the reason, this may dramatically reduce how many passengers can be moved. so more likely to be a luxury transportation than a widely used transportation system?
Sush! If you think critically about it, you will be called a neo-luddite! 🤫
Having multiple pods would circumvent this issue lol
@@bradleymarsh8583 yeah, maybe not a big deal depending on the reasons for small pods. and perhaps other challenges such as safety and loading could make it difficult to have many pods travelling close together.
@@guroux there are no shortage of engineering challenges that's for sure but that's why they have hundreds of engineers working on the same problem and eventually it'll be solved, maybe not soon, maybe not even within the next 10 years but sooner or later problems get solved. Splitting the atom, flying planes, re usable rockets, all these were deemed impossible and now within a century we have all of them.
Didn't you listen? The air is sucked out of the tube.
A hyperloop is an engineering hazard.
So was the airplane
For some reason, people can't understand the engineering issues behind large vacuum systems. A plane is TINY as a vacuum system in terms of volume and the magnitude of the vacuum. Simply put, it is childishly silly to think it is a viable solution. Period.
it's a hazard to everyone in and around it, but especially to those that sink money into it.
Decompression in a plane can be safely solved with a drop in altitude and gas masks until you get there. Decompression in a vaccum tunnel gives you nowhere to go as your eyes bleed, your blood vapourizes, and your insides try to squeeze out of every orifice. There's one of MANY reasons the hyperloop is dangerous and different from an aeroplane.
I understand the hyperloop won't be a true vacuum, but the more air there is in the tunnel, the less benefit there will be to have a tunnel in the first place. Even without the vacuum, such a tight, thin walled tunnel, that cannot have any air gaps and yet must cope with it's own expansion/contractions in weather fluxuations and tectonic movements over any fault line... it's a ridiculous amount of things to account for - utterly dwarfing the danger of an aeroplane.
Elon and his team have done great things, but there's a reason that MANY scientists are alarmed over the Hyperloop idea. It's an engineer had a thought experiment, but failed to take into account everything outside of the raw physics for it's feasbility. In fact, the hyperloop idea already existed in the 1950s, and it wasn't their level of technology that stopped them pursuing it.
@@challengegravity we've had a literal space station floating around the earth at 30,000 mph for like 20 plus years that has never had any issues with decompression lmfao. A simple hydraulic /suspension system to counter earthquakes (skyscrapers withstand seismic activity no problem) along with periodic hatches and compressed air stored in containers made to flood the device in case of any puncture or leaks solve all those issues
kind of underwhelming considering how much money went into this and how long it took
What's underwhelming? He said the exact purpose of it and proved the concept works. Reduce carbon emissions as well as revolutionize transport. Even if it takes 80 more years to perfect its still better than polluting and using the same tech for the rest of our days
@@bradleymarsh8583 Biofuel isn't all ethanol, and pretty soon we'll have algae-based jet fuels. Given all the preexisting airport infrastructure I think we'll luckily never have to see this disaster of an idea implemented
@@johnsmiff8328 yeah let's continue burning things to get around until the end of time and never try anything new. Let's leave all the cars and airplanes the exact same minus gas. This is the perfect world. Sitting in traffic but it's algae fuel being burnt off while we idle instead so its all good. Batteries are the future and we can't really run from that fact. Hydrogen fuel cells, bio fuel, all forms of energy that aren't renewable should not exist period. The earth doesn't have unlimited resources. It's mandatory we create infrastructure that can sustain us thousands of years into the future. Cars and airports and train stations have remained stagnant since their conception, minus the bullet trains that are actually proving how vital fast ground transportation is vital to building massive economies like China and Japan
@@bradleymarsh8583 Ok so a bit of a bruh moment on this one.
I'm not some big simp for cars, I actually have a lot of big issues with American cars-as default infrastructure, some of which I'm sure you share. I think trains are a great idea, and the US should have drastically more commuter rail infrastructure, especially in very urban areas. The problem with very high speed rail is that it's often very expensive to run. It has a role for sure, but not to the extent of China's very high speed rail, which they paid about an order of magnitude more for just for their trains to run a handful of kph faster. Trains are a great idea, but some degree of car infrastructure is simply non-negotiable in rural parts of the US, and you have to be understanding of that if you want to not seem painfully out of touch to 40% of Americans.
I'm want to make sure we have the same understanding of biofuels and hydrogen/oxygen fuel cells. The reason that a biofuel is net carbon neutral is that all of the carbon that it releases into the atmosphere when it combusts was carbon that was initially sequestered from the same atmosphere by a photosynthetic organism. This is distinct from burning traditional combustion fuels because you are not making a net CO2 addition the the atmosphere from a subterranean carbon store, you're effectively borrowing carbon from the atmosphere, there is no net carbon increase.
Maybe you know something I don't about the process of creating hydrogen fuel cells, but the combustion of hydrogen and oxygen will never release CO2, only water vapor. There are logistical problems to solve with hydrogen fuel cells, but the generation of the fuel itself can be done easily with renewable sources, such as solar, to provide energy for the electrolysis of water and subsequent collection of gaseous O2 and H2. The fuel itself is entirely renewable.
It's important to note that batteries have a relatively low energy density. That's why chemical storage of energy will likely remain relevant, like with biofuels. You may not like the idea of combustion for energy, but it's also more equitable for the global south, who are both too poor to buy most of the battery-oriented transportation products you seem to love, and are the ones who are exploited for the rare earth metals that go into electronics-oriented solutions. You're right, we don't have unlimited resources, so it makes more sense to cycle energy in the storage form of biofuels, made of plentiful carbon, hydrogen, and oxygen rather than in batteries.
That all said, vacuum trains like hyperloop have been tried for about a century. Reducing drag at ground level by reducing air pressure in the tube is just impractical. It certainly can't compete economically with air transport. Further, they talked about evacuating enough air from the tube that the pressure in the tube would be roughly that of 20,000 ft in the air. Depressurization of the vehicle in this low pressure environment would result in immediate and potentially permanent injury to the passengers. It's also quite difficult to maintain a leak-free pipeline with even a relatively narrow diameter, as we can see with the constantly leaking natural gas pipelines. A hyperloop is going to waste a lot of energy pumping out air that leaks in.
@@johnsmiff8328 I'll talk the L on this one cause everything you said actually made sense ya nerd
All hail the white paper! All hail the white paper!
every serious engineer and scientist just laughs over it.
it's an endless money pit and will never produce anything else than hot air.
1. more energy efficient than planes? maybe, dunno. but it uses way more energy than traditional trains.
2. costs ? doesn't seem to matter. you need the precision engineering and security of air or even space travel.
3. cost per passenger? why have a train with >400 people inside when you can have tiny pods with 2 people ...
4. vacuum: that is the main point that will break it's neck, literally. it takes hours to evacuate a decently sized container to the point where the hyperloop should operate at. why vacuum at all? the fastest modern trains can reach over 500km/h (TGV/Shinkansen) and maglev over 600km/h
How much more energy does a maglev train use compared to the envisioned energy cost of a hyperloop? I would think that unless hyperloop is *really significantly* more energy efficient, that it's super dead in the water. If it were *really significantly* more energy efficient, I could see the maintenance costs maybe potentially being worth it for some use cases.
The vacuum point is what gets me..
What's going to stop some dude with a drill who doesn't like the noise from punching a hole in it at 2AM? Or shooting a .50 round into it from far away?
@@asm_nop Right. How much energy efficiency do you gain from putting your maglev train in a vacuum? Is it worth the cost of maintaining the vacuum, and the cost of the infrastructure complexity?
Maintaining an efficient, and safe VACUUM TUBE measuring 100 plus miles in length, is an untenable pipe dream.. The biosphere project demonstrated our INABILITY to maintain a simple livable atmosphere inside a structure less than one 10, 000th of a percent of this proposal.. Maintaining a colossal VACUUM could be many orders of magnitude more difficult AND dangerous, an observation that many engineers and physicists have pointed out..O Well.. Peace.
Completely agree. Imagine what would happen if the pod/tunnel were to pop a seal and tear? It's a recipe for either a human lack-of pressure cooker, or a train car cannon x'D Maybe both!
I want to keep all the trains all year and every year.
Diesel trains, commuter trains, electric trains, passenger trains, freight trains, light rail trains and more.
As exitiing as you make this sound I fear that your wife was right
Yes, we should be exiting these ideas as exciting as they may sound.
They literally proved it works lol
@@bradleymarsh8583 They proved that it can drive a piece of aircraft externally powered in a straight tunnel. Yay.
@@SchlangeVonEden you know the Wright Brothers couldn't even get their plane to fly right? Yet they are still credited with the invention of the airplane. Lmao
@@SchlangeVonEden even if it takes 80 more years to perfect its better than going down the same road that has proven destruction
I want to keep all the Amtrak trains all year and every year.
Brilliantly delivered
Superb.....thanks for sharing....
Man I remember that ther was talk about this for Kansas city to St.louis some years ago and I was totally hyped. Then covid happened...
A fitting punishment.
One doesn’t experience self-transcendence, the illusion of self only dissipates - 🎈
I want to keep all the Amtrak all year and every year.
With the issue of providing a safe vacuum for the hyperloop to transport without any mishaps isn't present suggests that we still have a few more bases to cover. Hopefully we figure this out!
very HubTropolis ... Thank You³ 😊
Great talk
The secret of success is to do the common things uncommonly well.
John D. Rockefeller
Elon is trying to put spacecraft with wheels in vacuum tunnels on Earth. I don't think this is quite a railway anymore.
I don't understand any of it, but it sounds cool.
I want traditional rail trains.
I know nothing about tech, I just wondered how did they solve the very problem of a broken neck?
Thunderfoot Thunderfoot Thunderfoot Thunderfoot Thunderfoot!
Hey @TED, you all should leave this commy youtubing platform and move over to Rumble!
Literal pipe dream.
Finally tube technology!
Our governments can't afford to give people clean,fast, and convenient travel. They have us controlled in the most profitable way.
I love this vision and hope I can live to see the day that Hyperloop is a worldwide network of transportation.
Milwaukee just sold high speed rail line trains to Nigeria.
How to make our system future-proof?
Why was this posted 6 months late?
The only thing that worries me is the fact it'll probably be unnecessary difficult to repair because it's the engineers first version.
P.S. To the developers, please don't build any more knuckle busters. Thank you
I want zero emission trains.
I just came here to look for Adam Something related comments. Wasn’t disappointed ;) (btw. TED should have invited him on how to fix transportation… instead of this marketing guy who is trying to sell this inefficient way of transportation)
The only thing worrying me right now is that he's not the CEO anymore.
Explain your words, Judicator! (read in a protoss voice-over)
Traditional rail trains.
Aw man, I'm in Vegas often and would love to see this test area and prototypes. I've been fascinated by Tesla's influence and evolution of ideas ever since I found out about him. I hope I live long enough to ride in one.
No I want all the trains and Amtrak and Amtrak trains in the US and USA all year and every year.
But driving my restored classic muscle car is sooooo much better. Leaving my phone at home in a faraday cage, and NO GPS telling people where im at CANNOT BE BEAT. Ahhh, privacy.
i gathered that hyperloop might become more efficient after decades because it might be expensive to ride it .
I wonder it is true it goes fast but can you survive the G power and stay still for 30min without moving due to the g power?
you only experience G-forces as long as you are accelerating. When you move at a constant speed you do not experience any forces except gravity, think of an airplane
@@rasmusatterblad1885 hmmm it is hard as it should going that fast in narrow places, means corners need to be sharp it will be hard not to feel the shock. i really like the idea but do not like the execution think about the amount of construction it needed, like in America even the railroad . funny thing to know some country instal on purpose different kind of trainrails because if they got invaded the enemies will not have the equipment to use the rails
@@changyone Don't worry, you wouldn't feel the shock from a sharp corner at 600 mph.
Because you'd be killed instantly :D
@@samal3196 that's the thing for sure so what we will see is that city to city it is alright and doable but when it come to within the city it is not doable. They rather implement it for cargo
@@changyone And more importantly, light rail is gonna do the same thing but cheaper, for both :D
i summon Adam Something! watch out! he is coming!
Zero emission trains.
Fun fact: these videos makes our days better
ThEoDore is really on a downhill peddling vaporware huh
Y'all just got Hyper-duped.
I'm very disappointed indeed that TED ever gave space to promoting this crazy boondoggle. Every competent engineer/scientist I know laughed at it when Musk released this truly ridiculous idea. It's wildly over-complex and appeals to those who don't actually understand how 'technology' actually works in reality as opposed to some fantasy magic sci-fi world. And yet this video was released just as Virgin Hyperloop was planning to lay off half its staff ! The remnants of the company can't last long.
If anyone hadn't noticed, the idea of purely a single destination point-to-point service condemns it to failure alone. There simply aren't enough people who purely want to visit some particulate city highly distant from another single city. Here lies the advantage of the airliner. It can take you literally ANYWHERE it can land and it doesn't need a vacuum tube either ! Railway networks, similarly, can carry passengers to multiple destinations from multiple starting points. They are FLEXIBLE. The hyperloop idea is fundamentally INFLEXIBLE in its concept. And would bankrupt ant business trying to make one. Did NOBODY attempt a costing even ?
Oh and did NO-ONE notice that all those CGI animations showed only a SINGLE tube for TWO WAY traffic. Truly unbelievable. Get some psychiatrists to examine the common sense of people making this kind of delusional nonsense.
This still feels like fast travel for a small number of rich people so they can avoid having to slum it with the rest of us. The problem to be solved isn't how fast we can move a small number of people, it's how many total people we can move through the whole system to different locations. That is a solved problem if we just invest in existing mass transit tech (buses, light rail, high speed rail) and stop investing in ways to make things more convenient for the richest among us.
Guy never heard of train
Same old techie vaporware. 🙄
Flying planes were once vapor wave
@@bradleymarsh8583 not exactly. Airplanes weren't vaporware because the idea was based on sound principles. Hyperloop is not based on sound principles. The pod in a vacuum tube was envisioned a century ago. The reason we went with trains and subways in stead is because they're actually feasible.
@@MaskOfZer0 so the hundreds of engineers working on it are all insane liars? New tech and material science has made it feasible and that's the entire point of this video. Even if it takes another 100 years for it to come to fruition, doing the same thing we are currently doing just isn't sustainable and we're reeling from the effects already.
Superb innovation. ...keep at it
Best wishes

*bleep* Hyper-scam detected
The problem will be getting the land, the permits, the sound proof, where the power comes from, where do we put the stations and what stations are needed (cuz if NY to LA has 27 stops it really slows down everything) and everything in between to get it done.
We could have this already, fast electric trains already exist, it is the politics that held us back.
This is the future.
As a brazilian, I already disliked him from the moment he said "Wright Brother's historical first flight"

JUST BUILD TRAINS FFS
sounds cool for some places in the world that are overpopulated and warm, however where I live in Toronto they have a hard time building monorail systems especially in the winter. as for climate... i still dont know why people cant accept that the world oil will run out in 2050 anyway so were clearly going to use it till its done and see where were at with the climate then.
👏🏻👏🏻👏🏻👏🏻🙏🏻✨
Hi
Monoraaail.......Monoraaaaaail (singing) another Grifter selling BS. This has been debunked, keep up
Indeed delusional. His girl was right! Hyperloop One RIP
The Wright brothers invented powered flight like Christopher Columbus discovered America. It's a legendary cliché.
A closer look at the events of the time reveal that just like for the electric bulb or the telephone, many pioneers were working on the same goal.
The Wright brother's genius was that they thought of inviting the press while other inventors didn't..
Oh TED. 🤦 Maybe go watch a thunderf00t video, then come back here and remove this video like you did with the Elizabeth Holmes TED-Med video. 🙄
It's never gonna happen. It is just not efficient, realistic, it's hard to maintain(if somehow built), complex and above all unnecessary.
How's that hyperloop BS going?? 🙄
Bullshit!
Well I think Covid proved the Airlines are no longer viable, and this is cool AF! :D
las vegas was just 3 degrees Celsius... i say we let the warmer more densely populated areas deal with climate change which is pretty minor at the moment.. and let the planet warm.. the dinosaurs were put here for a reason to advance civilization if we really want a cleaner future wed be investing in new nuclear tech as well as this but oil barrons couldnt care less regardless.
see the positive side, you could use those pipes for oil later when HL went bankrupt.
Too much BS conquered TED... what a pity.
OFC he knows himself that he is talking BS.
scam
What a joke.
