cheaper to run and build than high speed rail. its also much more efficient. I think it would be cheaper than flying actually

Well smoking hasn't been legal on public transport in the United States for almost 30 years. So thats not an issue. ( and trust me 2 hours without a smoke is a lot less than the 20 hours it is now from NY to Beijing) as for bathrooms.. i bet they'll equip them with a bathroom.Originally Posted by B-rock

As for bathroom, go beforehand. If you can't hold it for 2 hours then you probably need to see a doctor.
Well if you need a cig, you pretty much can't smoke inside anyway. For good reasonsOriginally Posted by B-rock

Getting in a wreck would hurt.
Actually I take it back, you'd probably be dead so fast you wouldn't feel the pain.

how many of these would be needed for mass travel? Tubes all over the place... Or perhaps send one behind the other... Though, do you want to be in the second card if the first has an error or stalls. I don't think 4K speed collisions would be fun...
We can dream?

Only the first min is on topic - the gravity train stuff after it is wayyyyy ot

EDIT: Just on the possibility side of things, can someone good at maths compute this for me
![tongue.gif]( "tongue.gif")
The distance between New York and Beijing is approx 7,000 miles.
Max speed "tube transport" can travel = 4000mph
Approx weight of "tube transport" = 600kg (assuming similar weight to an F1 carbon fiber race car)
Max positive Gs an average person can withstand* = 3G (28 m/s²) for 10sec.
Max negative Gs an average person can withstand* = 2G (−19 m/s²) for 10sec.
So using those parameters above, and not going above 3G for longer than 10 seconds during acceleration, how long would it take the "tube transport" to accelerate from 0mph to 4000mph?
Also, using those parameters above, and not going below -2G for longer than 10 seconds during deceleration, how long would it take the "tube transport" to decelerate from 4000mph to 0mph?
While it may be theoretically possible for the capsule to reach 4000mph and travel between New York and Beijing in 45min, I am curious as to whther it is possible once you factor in human ability to withstand certain Gs before health risks set in.
If someone good at maths can do the above calculations, it would be good to see just how long it would really take to travel between New York and Beijing and keep the humans inside the "tube transport" alive and unhurt

* some people may be able to withstand upto 5G before losing consciousness or -3G before redout, but that does not make it safe for public use. +/- 2G is about the most an average person can withstand repeatedly.

2G's laterally is a lot different than vertically. You can take a LOT more abuse if the force is spread equally across your body, instead of from the top or bottom. Realistically, the only reason we are limited vertically is because the blood is forced out of our head, causing a blackout, or forced into your head, causing a redout. When the force is applied laterally, the blood in your system is hardly effected.
Perhaps when it's time to slow down, all they do is have the seats turn around 180 degrees. Would allow for a much more comfortable deceleration.

But I'll be very impressed when something like this takes off. I hate all the inefficiencies we have to deal with in our transpiration today. Fossil fuel, traffic jams, Commercial planes etc. I've only been a airplane once (that a remembered) and hated the entire gruelling experience of sitting down for 15 hours in a small enclosed space with 100 other people. If there's a new train that goes from na to beijing, you bet imma be on the first one

Honestly? No. Something ambitious like this needs more than just the governments but some big corporate sponsors with some geopolitical influence for it to take off. Not to mention there are plenty of other "interests" who already bought into the system who would not like something like this to happen...Originally Posted by venom55520
i have a feeling that this will be used for military personnel only.

i wonder how they will over come the problem of people going pop in these cylinders. at 4000 miles per hours i dont think our body can take that kind of pressure that these cylinders will get from going that fast??
Problem is if the capsule becomes compromised, stuck, or breached, the passengers will suffocate.
Spare oxygen tanks /w masks would be a good safety feature, but that requires passengers to be conscious in the event of an emergency. It also assumes that another tube won't ram you in the back side.
That all said, this would be excellent for transporting items. Imagine priority mail using these fast cheap pilot-less tubes which seem fairly fail-safe for non-living items rather than airplanes.
