Thanks for levitating my vid!
I said -- Earthquake? Levitate! Weren't you listening?
Ah so.
Now fixed.
Much thanks.
Arigato.

You might do at least minimal research before calling someone wrong:

You're Wrong Charlie, you get no lifetime supply of chocolate. They actually only said in the video magnets make it go up. They did not say it was a maglev train. These are entirely different animals. It is called evacuated tube because of a vacuum. Thanks for the physics lesson though.

The tube contains a vacuum, meaning there's no air to push or pull you forward. It must use maglev propulsion as well. The lack of air allows you to go 6500km/h without burning up or causing sonic booms.

Why couldn't it be cheap to maintain a vacuum? It doesn't have to be anywhere near a total vacuum (which is mechanically impossible, BTW), just a relative vacuum. Any reduction in air density results in decreased air resistance, and increased top speed. I don't know the physics of it, but I'm guessing that even a 50% air density vacuum would result in a massive top speed increase. In a perfect vacuum, the theoretical top speed would be (acceleration force) x (track length). This 6,500 km/h number may be a limit imposed only by how good a vacuum they think can be reliably produced.
And about safety, obviously the track wouldn't be built in a bare tube that could dent or break. The tube could be whatever material, but then encased in something else and/or buried so nothing could fall on it/crash into it/etc. Before it went into operation, for consumer confidence (and even before production, for investor confidence) it would have to be demonstrated that the structure is strong enough to withstand any reasonably foreseeable event. I'd be mostly worried about earthquakes, personally, especially when crossing the Pacific.
Just like with aviation and normal trains, it will have its growing pains and regular disasters, but I bet it ends up being on par safety-wise with flight, and significantly cheaper, given the fuel savings.>> ^shole:

they draw the air out of the tubes and use magnets to speed it up, which is very efficient due to lack of air friction
there's a ton of problems with this though
it would need to be (relatively) airtight and stable throughout
that can't be too cheap, whatever the material
constant maintenance
what if there was an external accident that dents the tube, like a failing support structure, and the train-car later comes to that dent at this huge speed?
it would be worse than a plane coming apart midair
great for scifi, but i don't see it being reality any time soon

Criss Angel pulls a Randi on Uri Geller and another psychic.
I dont understand though, I thought chris angel is the same sort of "actor". Why is he going up against this guy when angel says he can levitate etc.

lol at their puny lift.... when the big one hit Alaska in the 1964, cars were hopping FEET off the ground from the vertical acceleration.. when a nice one hit in 2002, it did this to one of our highways-

(man wouldnt you love to see that RIP! right in front of your eyes)
to summarize... i think this technology will save you from all the earthquakes you dont need to be saved from
Quantum Racetrack Explained!
>> ^MycroftHomlz:
How do you mean? The Miessner effect is purely quantum mechanical, in that, there is no classical mechanics analog for this behavior. And you need wave functions to explain the physics at all. If you want to understand it you can read Yip and Sauls paper...
>> ^westy:
No more or less Quantum than anything else
My point was that ultimately everything is quantum.
This only seems more Quantum on the face of it because its a counter intuitive behivoir at a human scale.
I think there could probably be a better way to describe it such as "magnetic Super conductor Wipe out" , "Magnetic levitation wipe out " , " super conductor levitation track" in this case the word quantum just seems to be used as gimmic / buzz word.
Still if it gets people to read into science and makes them exited about it cnt really complane
