Shanghai Maglev ticket is $8/single journey, compared to metro it is 12 times more expensive. Still, the government pays hundreds of millions CNY per year to maintain it.
It would be interesting to see a privately operated 800kphmph (wtf? supersonic?) tube running and actually making money.

I didn't know there was a maglev track in operation! :D

And yep, even if they are able to solve all the technical problems and safety issues, the question is if they can do it in an economically viable way.

A lot problems can be solved more or less "easily" if you can throw money at them, the tricky part is making things in an efficient and cost effective manner that still have the performance you want.

Qantas 32 had lots of error messages :P

I think the hyperloop is inefficient. The tube system in futurama even though much slower would be much more efficient as theres no vacuum, just pump air and only deal with the weight of people rather than capsules + people. Since everyone is transported individually there will not be any need for waiting so traffic going in and out will be smooth. This would mean a lot less cars and fuel.

Perhaps you like to explain those solutions in detail then?

Yep, I've been on it. Got a photo of the 400+kmh speedometer sign somewhere, but can't find it. It was awesome. The train passing in the other direction at the same speed was insane!
