Pretty cool design for fast traveling, they said they could get it to reach 4000mph because it would be a maglev with no resitance from air allowing it to go ultra fast

it also talks about a few other extreme engineering projects. You can tell the United Arab Emrates are definently a bunch of New monies from this as well.

pretty cool, new york to london in a few minutes. cant imagine how much it would cost.

i could see soo many problems in trying to build that... but cool idea.
Hate to say it, but 0FN. That edition came out about 3 weeks ago.

they also said on the History channel or discovery that it would take all the worlds iron producers like 4 years non stop to produce enough materials for the train not to mention the enormous cost to build

Yeah, don't forget that as well. But maybe someday we'll have a SPACE ELEVATOR!!!!1!!1 shifty!11eleven!

prehaps, nasa is thinking about it. and as for no resistance to air, impossible, unless its gonna go into fuckin space. there will always be some form of resistance, that thing will have to do with gravity and gasses, but it wont have to deal with friction from the tracks.
however! before finaly reading that, i realised they could make it underwater and make it into a vaccum, apears they are, but theyll still have to deal with gravity.

yea, when you think about ti that would be a huge waste of materials.

:lol: i don't know why, but I find that humourous.

and another thing, im not sure if this was covered in the artical, but because it is vaccum, and the surrounding water will be of such a large PSI, how would they keep it from cracking? and if and when it does, the water will go in with such a force itll obliterate all.
Screw that. I just want a video of some guy in a suit flying towards the back at 800 MPH when the thing kicks into full gear.

A nuclear submarine can withstand the pressures of those depths (150-300 ft) indefinately. I don't think a tunnel with reinforced steel walls (probably > 30ft thick) would have a problem with it.
The space elevator is a much better idea anyway. I could see that actually happening in my lifetime.

And let those Vanu motherfuckers MagMow us all to death? I think NOT!

*Zion hops on the train* "Boy this will be fun!" *Train starts and picks up speed* "Weeeeee!" *Suddenly, Zion is pulled back through his seat flopping into the others as he is pulled to the back and then....CLANK!* "My bones...they hurt...oh so bad." :D

That is suck a waste of resources it makes my brain hurt. But it is cool. But it'd be easier to just fly a plane.

Maglev train underwater... not only would it cost so much to make, it'd take a helluva lot of power to make it work.
Wouldn't they like, have to pressurize the train?
The tunnel is in a vacuum, so yeah, the train is pressurized.

Its old man, they are planing to build one like it from UK to America.

actually it sounds like allot of money, but it is quite cheap. it's not just a passenger train, you can put cargo trains in there too, think about it. you can buy fresh food from other continents, all the ships carrying containers won't be needed, it's allot of resources saved, and much much faster.
as for "enourmous pressure". a person can go as deep as 90 meters. the limiting factor happens to be oxygen which becomes poisonous if it's relative pressure is over 2 atmospheres. if 300 ft is 100 meters, the pipes have to withstand 11 atmoshperes of pressure. one atmosphere is 1 k"g per square CM. so that's not too bad at all.

In concept it's great. In reality, it would never work. Imagine that thing sitting in the water 300 feet beneath the surface, for thousands of miles. The ocean currents would move it in all sorts of directions, navigational charts would have to be amended for submarines (that's just our government- I can see the naval pricetag now), the sheer resources and manpower alone would effectively cancel out any profit, only certain people can afford its price range for immediate to short-term usage (no profit), not to mention the damage to the ecosystem it would do (that's just in terms of aquatic life ramming into something that shouldn't be there, not to mention the new habitats it would create in locations that don't cater to that)... and what if you have problems?
Leaks? Pressure cracks? Do you really want to be the guy on that train when it springs a leak or develops stress fractures at locations? Ever seen that Stallone movie "Daylight"? How about the dude who has to go in there and fix it... halfway across the Atlantic, hurricane season, 300 feet beneath the surface, and OOPS! Here comes Murphy's Law.
As far as pressure goes... you can go deeper than 90 feet. I have.

unless its gonna be naturaly boyent, and float in one spot in the water itll need stilts, and if it doest float in one place, i can see alot of stress generated along it by the ocean, all over it, and held in two places on two different continents, and all of that small, but ammounting current pressure, itll snap in half.

pay attention, 90 meters. oxigen is 21% of the air you breath. that means it's normal relative pressure is 0.2 atmospheres. it becomes lethal at 2. so if at 1 atm (sea level) it's 0.2 atm you need 10 atm to bring it up to 2 atm of relative pressure. if every 10 meters of water have the same pressure as our entire atmosphere, you need 90 meters along with the atmosphere to make 10.
pay attention man, I'm a scuba diver too you know...

Is it probable? No. Is it practical? No. Is it possible? No. Will it happen? No.]
It would cost too much to make, power, keep up, and is just plain stupid.
A Boeing-777 commericial airplane can reach top speeds of about 490 mph (789 kph). Not only is this cheaper, most people can afford it, and we already have it. No new things to make, no new planning. This is one of the stupidest ideas ever, making a maglev train across the Atlantic.

My bad. I saw "feet". Which is why my post said "90 feet".
