- Discover how the English Channel Tunnel was built and the engineering challenges of building a 200 kilometer long tunnel underwater.
--
Flanked by two powerful nations, the English Channel has long been one of the world’s most important maritime passages. Yet for most of its history, crossing was a dangerous prospect. Engineers proposed numerous plans for spanning the gap, including a design for an underwater passage more than twice the length of any existing tunnel. Alex Gendler details the creation of the Channel Tunnel.

I don’t even like engineering all that much, but TedEd always tells the most interesting stories
@SHOQSH S what he means is that engineers helped create the phone
i dOn'T lIkE eNgInEeRiNg aLl tHaT mUcH
tommy aronson a phone, and yeah, I’m well aware that it didn’t just pop into existence, it was engineered. I’m just not very passionate about engineering
Amgad Hasan I appreciate engineering and all that engineers have achieved, I just don’t have any passion for it
@@Maysra-tg6lx what's your passion?
I don't get GPS signal in a parking garage and these guys can get an accurate satellite position underground below the seabed?? 3:33
and my gps doesn’t always work properly, with my “location” jumping around the whole street, when testing it in my HOME, next to a window.
EDIT: I forgot to say that the meeting in 2 cm part is even harder...
Do you really believe the general public has the tech? 😂
They didn’t. GPS signal won’t pass trough earth and water, but you can track it outside the tunnel and get a precise direction and distance from that point into tunnel with laser guide.
Using a gyrotheodolite?
That's why they got to build it. Not you
TED-Ed always answers questions i wondered about as a child
th-cam.com/video/7LPNraEQTug/w-d-xo.html
Hai😍😍😍
❤️
Really! Then please mention your answered questions which u had in childhood
Does that confirm when we grow up we actually become like robots that just work eat and sleep without questioning anything ?and when people do for example about the government (covid) we call them conspirator…
Nice job.
Projects like this one provide a lot of value for humanity !
th-cam.com/video/7LPNraEQTug/w-d-xo.html
Humanity? More like Britain and France.
"Humanity is at their best when breaking down barriers."
Coronavirus: are you sure about that?
We’re not at our best because of these barriers. Coronavirus can easily be dealt if we all work together.
@Ricky you know, ideology...
No little bi***" can't do anything to us if stand together. But not only on a emergency situation, we should stand together for everything like saving the humanity from pandemics to climate crisis.
relax, its just a quote, don't take all literally... gosh, why you people always takes anything so literally
Yes, we can eliminate the pandemic only if medics and Countries will collaborate together and share information
Imagine the workers from both the sides met with one worker standing a foot above the other. That would've been such an awkward handshake
Jay Joshi Haha i think they didn't give a fck mate
They would be so happy then notice and be like it was france not our fault! Then the french workers would pull out a stale baget and the british workers would pull out rolls of _aluminium_ foil they duel then after the battle would drink some tea and talk about there exploits the french would proceed to murder the first englishmen that made a "surrender" joke this is about what i think would happen probobky

Imagine if in the faraway future we'll have such a bigass project connecting the US with spain and this happens because one country was not using the metric system

Anglo-French engineering produces some incredible feats when the two sides work together. Such collaborations produced icons such as Concorde, the Channel Tunnel and the Millau Viaduct.
I'm from America and had no idea this even existed, but I'm glad I found out about it; it's amazing!
Haha, of course you are ;)
The magnificence of this project doesn't lie in what was accomplished, but in the coming together of people from different lands to build something that benefits everyone. Together we have unlimited potential.
I love getting informed on such random topics its kind of refreshing.
It would have been good to hear more about the navigation technology that allowed it to work through the rock and water above, rather than just "satellite navigation"
just like egyptians using mirrors for illuminating inside, but these "mirrors" transmited the gps signal outside the tunnel, on both sides, the spot on satellite was on both exists, and the inside of both tunnels was calculated, just like @maxim s. bagaev said
Here is Parliament of India

For the first time Im actually pretty early for Ted-Ed like literally I've only seen videos like 5 years ago.
M0rningSc4ree true
How do you build a tunnel under water? - Do it in the rock beneath the water.
xinyue ma some tunnels are in the sea-bed or river-bed
Every time the machines came close to one another, I held my breath.
STOP TOYING WITH MY EMOTIONS, TEDED!!!
ive crossed this tunnel in both directions multiple times in my life, and have now only just realised it isnt on the seabed but beneath it. well done me.
I wish all my classes were like this. I'd look forward to every single one.
Pretty decent presentation of the story. One bit you left out is that toward the end of their journey the UK TBMs were driven down into the ground, clear of the tunnel and the French TBMs finished. So, the TBMs didn't meet in the middle like depicted here. Also, the political bit at the end was quite unnecessary.
Richard Forester The political bit at the end was completely out of place, this is a video about engineering, not globalism.
It was perfectly apt. What's your issue exactly?
Agreed. This is about how the tunnel was built, not the creator of the video having a hard-on for so-called refugees. They’re not trying to cross the channel to get to safety - they’re in France, they’re already safe - but because they want the easy benefits and free healthcare of the UK. It’s greed not fear that drives them.
@@firstname405 no it wasn't

That end quote got to me. "Humanity is at their best when we break down barriers." 🙌🥰
2:42 - Nope, I see no problem here, this looks fine to me…
3:58 - That's an unfortunate name, even in England where it means something else. :-|

Yep my guys about to get drilled into shreds
I did'nt even knew that such a tunnel was possible and that it actually exists. Thank You Ted Ed.
luckily it wasn't built by Elon Musk's Boring company
It's so entertaining watching this as a student studying civil engineering
Those 10 workers died are heros that gave us opportunity to have better Transportation... Salute!
The introduction to another related video at the end of this video is smooth and triggers our interest in simply knowing more.
Humanity is at its best by breaking down barriers. but those refugees should learn to respect the laws of the land, which they don't.
Don't agree with the refugee part but nice video
Astounding visuals! I really dig 2:06.. and the other worker animations
This video was really interesting! Thanks for making it Ted-ed.
Graham WHO!?
when i was little me and my family went to europe. they said we would go into an underwater tunnel. now i thought we would be in the water and i was so excited! then i realized it was UNDER the water, not under water. i was so disappointed.
I used to think that too lol. I thought it was a literal tunnel through the sea channel. I was shocked when I was kid and found out it was under the sea and not through
Graham Flagg. What a name!
I love to watch videos of TED-Ed ,especially when the narrator sounds calm and a voice you'd listen too
"The British anticipated drier conditions" - Whaaat? 😆
Can't agree more about the intro quote. We always come up with intellegent ideas (especially with technology) crazier than what we happen to predict for future.
"Humanity is at their best when breaking down barriers"

@@johnkneeboi369 What? Globalism or Cosmopolitism doesn't necessarily mean Communism. Or are you saying Augustus and Cortés were communist too?
@@hermannbarbato globalism is bad... and communism has to be global to work ...
@@zejdlandYou're confusing Globalization with Globalism and Globalism with Communism, these are three very different concepts, although one might include some of the others.
One of the biggest achievements in human history i guess! This is just something beyond fascinating... To challenge nature and tunnel through the sea... It shows that humans can do most of the things that seem impossible today in the next 100 years...
My dad worked away for weeks and weeks painting the tunnel in the 80s, I was born 83 and I remember he was away quite a long time painting. He told me it was an underwater tunnel and to my 6/7 yrs old brain I asked him how he breathes painting underwater and he told me he had an oxygen tank like a scuba diver! 😂 It made sense to me, he's a cheeky git! He's 66 now.
Simply astonishing
"humany is at theyre best when breaking borders"
UK : BREXIT
LOOL
UK going backwards
@@Yusso seethe more
Ted-Ed seems to be endorsing uncontrolled immigration across the uk border. Dont quite know what it has to do with America but yes let's all get along nicely. Nevermind that any genuine refugees have to pass through all of Europe, and countless safe havens, before they reach England. The people trying to cross are not refugees they are economic migrants. And those borders that apparently need to be broken are the only thing stopping an extremely generous and abusable uk benefits and support system from being completely decimated. Wonder what Americans would think if the British started telling them to erase the Mexican border because 'we're all in it together' and 'yay humanity!'
@@hankjones7054 we do need to enforce borders but honestly the refugee/illegal migrant detainment centers are awful. They literally separate children from their families.there's a better way to detain.

@@BeaverChainsaw I don't understand why you don't just send them back to their countries. Take in thousands of unsurveyed people from developing nations and crime rate, unemployment, and general social unrest will rise. The developing nations lose as well as they're losing workers, it's a lose lose.
I would like to appreciate the fact that Ted-Ed took the time to read and like a bunch of comments.
TED Ed: Humanity is at their best when breaking down barrier
Vikings: Sweet!!
i had literally no idea this tunnel existed until I saw this video. cool stuff lol.
France: Hey Britain, lets build a tunnel below the English Channel to connect our countries! We'll be so much closer to each other!
Britain: *PTSD flashbacks of a thousand years of continuous warfare*
being an isle now doesn't matter.
If they fight the French, they're finished.
TBM sure is a piece of art. A single piece of equipment capable of digging, transporting, and lining the tunnel. I'd love to be able to see this in person one day.
We are living in tough times.
However, now is the time, more than ever, to believe in yourself, to learn and grow and hopefully become a little wiser.
I don’t know who you are, fellow internet user, but don’t say no one cares about you or believes in you.
*Because **_I_** believe in you.*
That profile picture says otherwise lol.
Friend, whether or not you made this account specifically for this post, you're very nice. I appreciate it.
They are not refugees, they are economic migrants. Nearly all of them are males aged 18 - 30. Lots of which have left fled their homelands even though there was no war happening. They've passed through numerous "safe" countries trying to get to the UK for better benefits.
As evidenced by the fact that they're waiting in _France_ to cross to Britain.
Oceans 13 taught me everything I need to know about the channel
I was hoping to find this comment 😊
Brit & Fran in 1994 : Hooray, we have a tunnel now...
Japon : Hold up my Seikan Tunnel. :v
Not really the same thing, Seikan Tunnel is a bigger tunnel but it's length actually underwater is far less than the Chanel tunnel.

Wow, that obnoxious anti-white angle at the end was so unwarranted. Imagine being so stuck in an eco-chamber that you think "unfortunately borders exist" would go down as a neutral statement.
it isn't neutral, it is pro humanity
I am a student and thanks to Ted ed that I can still learn so much sitting at home!
Finally I'll be able to show off my knowledge to look cool at parties
You already look cool for me.

Corona virus proved we need boundaries more than ever
The English channel train tunnel officially became my dream to travel in it as an aspiring civil engineer 👷♂️.
IK I will sound like a stickler wehraboo, but the advent of aerial warfare does not suddenly render the English channel a useless means of defense. Ask the Germans how well their aerial assault on the UK went.
that was just the beginning of a great innovated idea
No visa, no entry, easy.
The more I think of underwater construction, the more bewildered I am
At 5:06 , "that humanity is a their best when breaking down barriers" the question of open borders should not concern Ted ed and what's worse is a point of view which they would endorse on this issue. What kind of education are you giving people? A biased education?
Chill out Karl lol they’re allowed to have opinions
I'm impressed with how you want an educational series on human triumphs in various fields should leave out the "human" part. Be real you are just upset b/c someone like yourself has encountered a story from history that supports an opposing opinion. I doubt you go around responding to anything you "agree w/ " on how it is biased.
Absolutely incredible. I don’t care what you say, humanity is beautiful
England is a sovereign country and can decide who can and can’t enter , they have a right to their borders. , like you have a right to keep people out of your home.
