This clearly doesn't exist yet, but think of travelling at those kind of speeds, through a tiny tube...
Kind of like you're a deposit slip travelling through the tubes to the bank teller.

Awesome! Imagine what the scenery must be like at that speed, provided these tubes have transparent windows and whatnot.
On the flip side, I'm sure accidents would be catastrophic. Like, if someone farts, the air will all be trapped inside.

Ok, so the tube itself is frictionless. That's great. Not really possible, but great.
The contents of the tube though? Unless they (the people inside) are floating in the air, and somehow still get propelled with the tube, as the tube moves, then they're going to be feeling some pretty serious g-force. At that speed :wtf:
I've been drinking, whatever. Acton needs to sort this out for me. Physics degree, and all that.
I summon him.

Not impossible i think very improbably with todays tech. The issue my non expert mind thinks of is keeping the perfect vacuum this would need for the whole lenght of a tube. If theres any air where there supposed to be none you have friction and thats not good when youre doing 6500km/h.
The g shoudnt be a problem thogh since its only experienced when accelerating or turning. Good line design should keep the turning theoretically to a minimum and at a constant acceleration of 1g (as stated in the video) they would reach top speed in just over 3 minutes. Not much of a problem there.
The issue is, if anything goes wrong, what you have is an out of control projectile with a mass of approximately 558kg (183 for the tube things and 5 adults at 75kg each) travelling at 6500km/h.

lol friction

The theory is good but that's not safe enough. As my Balkan compadre touched on, a small error and it could be catastrophic.
I can see it being used underground for shorter distances, say from the CBD of a city to various hubs around the city. Would be an awesome way to revolutionise public transport.

That was my very first thought, reason why I said accidents would be catastrophic. But I'd say that's not the worst problem, because if this supersonic projectile hits a person, it's going to be a quick instant death.
If, however, the tube is not properly sealed for whatever reason, everybody is going to suffocate, and I reckon this is a much more painful way to go.
