Wasn't this on the Jetsons?

If it's similar to the Atmospheric Railway, then maybe not just the Jetsons.

[QUOTE = Musk]What you want is something that never crashes[/QUOTE]

as far as I know this is only possible with magnetic levitation

Musk tweeted back, "your guess is the closest I've seen anyone guess so far."

No one need question the wisdom of moving the rabble about at an ever more faster rate.

The more important question: will it have a bar? I think not. But even if it did the only beer served will probably be Miller High Life; in a continuous hyperloop.

The Jetson's was a cool cartoon. Shows my age that I even remember it.

However because i couldnt resist with all the -loop- thing to make you laugh, since you have to drink endlessly those beers anyway, at least do it in style;

Try a gigaloop instead. Also known as giggle loop;

That's damn cool

musk supposed to be revealing this around 5pm est today. trying to find a link.

From Elon Musk's Twitter:

More like this to go directly;

Essentially this is like above links earlier in this thread's history that describe vactrains, no?

So I've read the paper. Fwiw I have a bachelors degree in Mechatronics Engineering but I am still a noob so take my opinions with a grain of salt.

The paper seems very reasonable. Everything seems to be doable and most things rely on technologies we have a lot of experience using.

Seems very cost effective and scales well(could handle all car traffic today even v1).

The customer experience should be vastly superior to flying. South Park...

It will need a lot of batteries, can see Elon making some profit there. Unfortunatly lithium is kind of rare


Will be interesting to see what more experienced engineers says and see if anyone wants to try and build one. Seems like Japan and China should be very interested in this.

Interested enough to be already doing it as the vactrain links above suggested;

Hyperloop Physics 101 with Elon Musk

If this train got me to work, for example, it could save me approx $400 a month. I drive a Honda Fit by the way.

When people have more money, and spend locally, I don't know if any of the papers accounted for a potential boost in economies? Maybe I'm looking at this wrong?

Seems to me I read about this in Playboy around the time they first started showing airbrushed vaginas.

PTB

What's this new tech madness? if God wanted us to ride in cannisters in high speed air tubes, he would have made us bank deposit slips!

They could do with this instead of the proposed H2 train in the UK, London to Birmingham!




Some estimates thinking more like 70bn.

Erm, whole new 4000mile/hour tech instead pls.

How brutal is the disaster if it's running at capacity and a section of tunnel breaks open/apart for whatever reason?

It would be carnage... so much energy involved!

It would be a quick death though... My theory is that a lot of the fear of plane crashes comes from knowing/thinking you are about to die for a few minutes as you plummet to earth...

Dodgy tunnel at 4000mph.... you won't know much about it until you're playing chess with Einstein or something..

Eh, probably not that bad, top speed 340 m/s and 5-mile spacing it shouldn't really be possible for more than 2 pods to run into a wreck, maybe not even 2.

Just paint the thing and its surrounding red, and we are fine with closer spacing.

Yes as you said calculate the speed the effect travels. Probably a combination of extreme pressure wave travel (sound speed) and http://en.wikipedia.org/wiki/Maxwell...n_distribution typical speeds at that temperature , not very far from the air speed as well.

I suppose you can have computers monitoring air pressure at all regular points and if something fails all the system is decelerated in advance of the "air strike" lol so that it can be prepared for it better. Or it may be possible to close down a part of it while doing this shut down and contain the situation. But really what could fail? It probably will be a very deep tunnel or very strong structure underground that would sustain even a plane dropping to it . Could an earthquake break it? They probably would have calculated some maximum it can take in the paper if i recall.


It would basically feel like an explosion only about 100-1000 times less severe fluctuation in pressure than that of a big bomb detonating nearby.

It probably wouldn't collapse the nearby structure further breaking the tunnel but would damage some internal structure to a point, just propagate the rapid loss of pressure like a horrific max recorded speed hurricane times 3 lol. Nothing short of substantial internal damage though like a large scale small intensity detonation.


Its old news really though (vactrains), simply someone deciding to go into its details as a news event when China is already trying in that direction since 2010. Also some Swiss work was done on such tunnel train proposal last decade (Swissmetro) but it didnt continue. Someone better do it and do it in ways that it can move also cars and cargo as it would help mail service delivery too across major cities and have some additional economic benefits. The problem is however that it is pretty expensive per km built (maybe about 20-100 mil $ per km?) so it you consider very large distances say >3000 km to connect the 2 coasts it looks getting to as much as $150 bil.

I suppose air travel SF to NY is order 1 mil $ per day volume? Am i wrong? More than 10 flights times 300 times 300$ each? What is it, anyone knows?

Probably still somewhat problematic if you are on said hyperloop.

Something or other about how people misunderstand risk should be inserted here. Something or other about being super efficient always creating an Achilles' heal should probably also be inserted here to balance things out.
