The key advantages of a tube vs. a railway track are that it can be built above the ground on pylons and it can be built in prefabricated sections that are dropped in place and joined with an orbital seam welder. Did anyone else read this and imagine laser beams fired by satellites?

But in China vast expanses of high speed track are built on pylons. Here is an example of one such track (and some unfortunately placed apartment blocks): http://msnbcmedia.msn.com/j/MSNBC/Components/Photo/_new/pb-1...

Doesn't look any more cramped than the back seat of a car.

...which is pretty cramped.

Yet still tolerable for a half-hour journey.

How do you get out of there in case of fire? If the doors open like that I don't think it would work while inside the tube wouldn't it?

Right, but the Hyperloop journey as proposed is 35 minutes long. It seems a reasonable trade-off to me.

It's a 30 minute ride.

Try LA to Sydney in coach.

How is that any worse than standard commercial air travel? Plus, really, you are talking about a thirty-minute journey.

You can get up and walk around on a plane.

Not for the first 30 minutes - which in this case is the entire trip.

Thought this was amazing: $20 for a one-way, 35 minute trip from SF to LA.

Well it has to beat a standard commuter car (~$45 one way@34mpg) by a significant margin to be useful for consumers.

What about freight?

I'm not claustrophobic, but this image ever so slightly terrified me: http://i.imgur.com/lGD9bUP.png

I have to wonder, would making the capsule the size of a small subway car completely destroy the economics of it?
