T.A.T (TransAtlantic tunnel)
-
Recycled or not, it still looks excellent. Is that the same HDRi generously shared here?
-
Excellent, Herr Solo.
The struts supporting the tube look flimsy for such a structure, especially considering the stresses produced from such high speed trains. -

-
some materials could be strong enough and still be that thin, carbon nano-tubing maybe?
-
I'm guessing by the time we are ready to build something like this, which will by far be mans biggest engineering project ever we will use the cutting edge technology and materials available at the time, like spider silk cables (cannot rust and strongest) light weight aerated concretes, carbon tube rebar, etc.
Here is the concept of freight.

5hrs on plane with the possibility of escaping a malfuntion. Or 3hrs on a train that if trouble starts i'm goosed. I'll take the plane anyday.
nice stuff so far Pete

Rich, do you carry a parachute with you when you fly? You should give us some pointers on how to pass it through security.

Your actually allowed to take a parachute in most commercial airlines I think!?!

Well, if a plane losing both engines it can still ditch. If it loses flight controls it can be guided by engine power. And aerodynamics isn't gonna change as it's a law of fluids.
Now for my train arguement....
what if a big fat whale and a giant squid decide to fight on top of the tunnel. well?......huh? Not so safe now is it?
-
seal the section ends, blow the explosive bolts and take the section up to the surface (I'd assume surface pressure in the trains so you'd only have to account for equalizing the tunnel on the way up)... extend radio mast and transmit SOS...
-
I dunno Rich, the tunnel is 100 ft below water surface, it's electric and fast. I'm guessing it will be cheaper and safer, there can be as many as 50 trains at a given time with 1000 plus passengers travelling to and from New York.
Another advantage is faster cheaper shipping, we all win there.The tension cables are computer controlled and there is a sway tolerance, should a blind whale hit it, I doubt anything will come of it, a submarine is another story, however terrorism will always be all human transports biggest worry.

I know...I was just ignoring those in an attempt at being funny..oh well

They would just call Arnold Schwarzenegger, save the day and make a movie in the process.

yeah i saw that a while back....would be one hell of a trip! although the figures involved in manufacturing were huge....every single steel works in the world working 24 hours a day to produce enough steel!
-
where's the like button on this faceUcationSketchBook page?
-
Just get Chuck Norris to whup up on them whales and squids, long as we're puttin' in multi-thousand mile tunnels and such.
-
The cables should be made of carbon nanotube fibers.

You CAN do it if you really want it.
In the film 'Sunshine' [when chronic global cooling results from the Sun stuttering] the nations of the Earth gets together to send a space-ship to the Sun and then launch a massive explosion to kick-start the Sun's reactions again...
The film follows the second mission after the first one has failed - each mission costs 4 years of the entire Earth's GDP !!!
I know it's fiction... BUT if push comes to shove we can do whatever is needed - look at WW2 - ridiculous sums/lives spent over a few years to what ends...

Reading the original post, what first came to mind was super sonic boom, and movement of the earth's plates. Each immense engineering problems. I'm sure that it won't be difficult to think of more. Didn't even think about the manufacturing, and economics ones. Makes going to the Moon fairly easy. Wounder what the EIS would find. If one were required when air transportation was first created, perhaps planes would not have been allowed.

A 'Lamson Tube System' is old technology http://en.wikipedia.org/wiki/Pneumatic_tube
My local supermarket uses one to whizz capsules of banknotes from the tills to the office.
The only difference is a matter of scale [something the size of a 'small football' becomes a 'train']... and distance... 40m becomes 4000000m... and the contents aren't inert pieces of paper but human beings...
Apart from that it's all quite doable -
The original Discovery channel idea was based on that, They recon with today's technology it could take weeks to create a vacuum in a tube that size using the biggest pumps available.
These are huge ideas, science fiction with today's technology, but who knows, this could be a reality sooner than we expect as technology breeds technology.
