Extreme Engineering - S01E03 - Part2/5 - transatlantic tunnel

[Bloodstream2010]

I come from the year 2152. No bridge was built. We went to mars

[hop208]

Couldn't the airtight tunnel go over the land in Greenland and Iceland as well? It would have to, to keep up that speed. Why would they have to worry about the wind in an airtight tunnel?

[CinnabonChan]

God, how awesome would that be. I could have a late lunch, then I could do a bit of shopping in Oxford Street, pick up my auntie's favourite chocolate and be in New York in time for dinner.

If only I was born a century or two in the future.

Everything what is in our imagination will be done some day. The only thing we can't do it is when we can't imagine it. There is only question when? Todays technology is like a caveman technolody trying built the airplane. But there is one thing wich speed up everything thousands of times pretty soon - called "NANOTECHNOLOGY" - sample? "GRAFEN" - speeding up our PC from 3 Ghz over 400 Ghz, or changing the colors without painting or clothes never get wet on the rain...and it's very very beginning

[vettedreams]

never gonna happen

[RomanHistoryNut]

This isn't possible just like it wasn't possible to go to the moon in 69 with a giant bottle rocket, air tight box, and a gameboy.

@RomanHistoryNut

It's 2099 88 years after today.

[Zalis116]

But I thought Greenland was melting due to climate change? Surely weather conditions by 2099 will be warm enough to allow the overland route.

I don't think they could ever use the rectangular building methods for the sections for an application that deep. You'd need to at least encase the whole thing in a pipe shaped sleeve due to the inherent strength advantage you get from the circular profile.

This is, not coincidentally why you almost never find square windows in airplanes and many ships...or really anything that has to operate outside of normal atmospheric pressure that also needs windows.

[RebornLegacy]

the videos in this clip make it look like their already building it

[kitwann1]

Vacuum travel the way forward but the OIL GANGSTERS will stop any plans.Vacuum is cheap to run and can use no fossil fuels ,talked about in 18th century we are still in the petrolheads grasp.

[bbtvN]

@kitwann1 You?Oh no,oh no.

Best way to have fuel:Bomb the whole earth lol xD

[AlternateArtisan]

this is like, the modern equivalent of building the pyramids. Except it'll need the whole world's cooperation and not just one nation.

[DKJonex]

I like (sarcastic) the part about the Mid Atlantic Ridge at 00:15. The producers of this documentary argues that it wouldn't be possible to drill a tunnel through this part because of volcanic and seismic activity. But they do not even think of how it should be possible to anchor an immersed tunnel in this area!?

It woudn't be possible! I must say that this documentary is absolutely unrealistic.

first let's work on a rail or some sort transportation system that can travel faster than a jet otherwise why waste money. future jet on the drawing board that can go to the edge of space then fly 5 times the speed of sound then slows down then descend towards its destination. no sonic boom because at the edge of space there's no air.

I think they screwed up citing the pressure at the bottom of the ocean. Challenger's Deep, is the deepest ocean trench explored by man, and is around 16,100 PSIA (1.25 ton/cm^2, 110 MPa). "Over 800 times atmospheric pressure" is over 800 times ~14.7 PSIA or over ~11,760 PSIA. Considering a depth of 35,800ft for Challenger Deep and weight density of water to be 62.4 lb/ft^3, this gives about 15,470 PSIA. So 12E6 PSIA is definitely an error. Even ~16K PSIA is not 12E6 lbf/ft^2 (2.3E6 lb/ft^2)

[qoohkLive7]

wow SF's BA??

what about the Hong Kong's MTR

sooo much more modernizee

[123chiragkumar]

I like the idea. I had a dream about this. The only thing that they did not mention is salt carotion? In long time this can effect the bridge

[SawViking]

i like their first idea best: about putting the cross atlantic through greenland and iceland. goes straight to my house!

[ColdZer04]

This is one of the reasons why I want to become an Engineer. XD

[LouistheHedgehog]

@ColdZer04 Be sure to take calculus and physics then.

[R1DV4N91]

@ColdZer04 Im first year on Civil engineer collage =)))))

[fudgeDcosta]
