The Hyperloop: BUSTED

There are lots of challenges many of which could be showstoppers if they can't be solved. But that's just a matter of engineering. I'm sure it could be done. The question is more the economics.

The economics really bother me. Is this suppose to be more cost effective than a concrete channel operating at atmospheric pressure or existing fast trains?
And I would consider the engineering and economic problems secondary to the political problems at least in the US. There are lots of government actors who can say no to something and none who can say yes. (1) And government actors do not get paid for not objecting.

I can't see much point spending tens of billions on a single 300 or 400 km/h train route when a lowly Dash8 takes 40 - 60 passengers at over 500 km/h with infinitely flexible routes between any arbitrary pair of towns less than 1500 - 2000 km apart that each possess a 1000 - 1200 meter long airstrip (or less, with reduced range and/or passengers).

And in the US once the TSA gets involved, it will lose all of the advantages of not dealing with the TSA at the airport.
(1) The way I remember it, that was how Southwest Airlines was able to get started. They got a route between Los Angels and San Fransisco where since it did not cross state lines, the federal government had little say in how they operated.

busted as in, not practical.

The track is really cheap to build.

I'm actually on a hyperloop team and the main thing being talked about at the moment is cargo, not people. Sending shipping containers from one end of the country to another at 3000km/h is very attractive.

Not compared to "no track" for a plane (or rocket).

300 km/h matching or beating most fast trains I can easily believe.
800 km/h makes me go "hmmmmm"
3000 km/h completely fails to pass the giggle test.

It was supposed to be more cost effective than the existing California High Speed Rail project. That's the whole reason for the proposal.
