# [io9] Real-life Futurama tube-transport will catapult you from New York to Beijing in 2 hours - Page 10

What if some idiot decides to drill a hole, saw through, do something to the tube? 7,000 miles is a lot of tubing to protect.

Law of gravitation obviously. F=MA would also come in handy, and V=IR, and other handy odds and ends like that. The fact that I care about this stuff is the reason a college drop out like me is making more money than most of the people who forgot it and got Communications degrees instead.

And how is that any different from if a plane "just stops"?

4,000mph or 600mph, you are dead either way. Heck people die in 30mph car crashes, albeit less often. The speed does not indicate the safety - statistically flying is safer than driving even though it is ~10 times faster.

As I said before, there is such a thing as an inductive maglev track - if you cut the power the car will glide to a slow speed (1-2mph) before it stops levitating. Put some small wheels on the bottom and you are sorted. Far better than a plane loosing power.

As for "mass deaths", 6 people in a cabin at a time kind of limits the potential for large numbers of casualties. Compared to a 800 person air liner you are probably going to have fewer deaths even in catastrophic failures.

What if someone puts a concrete slab on a rail road track, or pours diesel over a freeway? There will always be idiots, you just have to try and protect against them the best you can

So many 'if this thing messes up' - you guys are the same people preventing progress in other fields. Don't do that! It's scary and could potentially be dangerous because it appears to pose a risk to a person's health!

*grumble*

I would assume they would have some kind of counter measures in the event of a failure/complication.

On the flip side of my post, I openly welcome a transport system like this because I've jumped out of perfectly good airplanes from 12,000+ Feet in the air on a whim (and other times because I was commanded to do so ).

Interesting to see how this will play out.

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.

I agree, a system like this would be amazing for companies to ship items. Online shopping has really picked up lately and the only thing physical shopping has over it right now is how soon you can get it. Quicker to driver somewhere then order it and wait a few days.

It's impractical. What, you expect hundreds of large tubes flying out for people and transports?
It will most likely cost more then a plane ticket.

Many people would also lose jobs, especially international shipping companies such as DHL or EMS. They may try to prevent it.

Yes, Depending on how much at a given moment.

A liquid buffer might distribute the pressure on the exterior shell (of the egg or the capsule) and prevent that from crushing, but it does not magically alleviate the G-forces experienced by the contents. At most it might act as a shock absorber and alleviate transient G-forces, but would not significantly affect the average G-force. And the shock absorber effect could probably be achieved by less massy systems than the several thousand kilos of water your description would require.
@Everyone: I find OCN's lack of physics education disturbing. There are people here screwing up even basics like F=MA and the difference between acceleration and velocity. Come on guys, you're smarter than that.

I find your lack of modesty,and integerty disturbing along with your arrogance.

Regardless of what phaedrus and gingerjohn have said I've enjoyed reading the discussion.
Phaedrus, most people dont use enough physics outside of college and honors high school classes to retain the information. Its a waste of brain capacity to remember even low level physics when you are unlikely to use them again in your life.
If you had to make a choice between remembering your wife's name and Newton's law of universal gravitation which would you choose?
I find your lack of faith disturbing, to quote one famous antagonist. At least people here are trying. This a computer enthusiast forum not a physics enthusiast forum. Go post it on facebook and see how many people can even tell you that v0 =/= a =/= s
Your attempt to insult the entire group that is posting in this discussion is petty and frankly, I thought beneath someone like you.
But hey even paid observers like myself can be wrong about people!

Well said

Oh wow again! Keep up the good work man

while a can agree phaedrus might have been a bit harsh. it IS, however, a bit concerning to see the lack of rudimentary physics knowledge. especially given people in this thread are stating ideas as potential solutions to concerns by other posters when they have no grasp of the subject. in high school i was taught (gr 10 science, which is a required course for your diploma) basic physics bio and chem. i still remember a great deal of what i was taught, even though i have never really had to apply any of it to what i do now or did in my previous college schooling

Keep in mind that not everyone in this forum has graduated from high school yet! Not to mention, physics is often not a requirement. At some high schools, you choose your science: Biology, Chemistry, Geology, or Physics. You'll find that a lot of people don't find physics interesting.

That aside, not everyone is wired the same way. For instance, I can imagine an engine and transmission operating in my mind as I drive a car. I know what my inputs are doing, and why I get the response I do. I'm mechanically inclined, and tend to be left brain dominant.

My sister, on the other hand, has no real idea what her inputs are doing when she drives a car. However, she can take the simplest concept and create things I could never imagine. She actually is a communications major, and has worked at major advertising firms in New York and LA. She is very right-brain dominant, and very smart, but it's applied in a different way.

Sometimes it's easy to forget, and get frustrated that not everyone grasps a certain concept as easily as you do, and sometimes people flat out don't care to. However, the ability to work with those that are "opposite-minded" is critical in life. Logic can create make something very efficient and creativity can make something abstract and new. When both types of people work together, we end up with a brand new concept that is both abstract and efficient... A deadly combo!
