Which is extremely expensive because it has to withstand huge forces trying to crush it like a an empty coke can..
Hyperloop is neighter "cheap" or "easy" to create. Its approx. 10 times as expensive to operate than "Mad-Lev" trains and 100000x as deadly if something goes wrong.
Malfunction in electric train means that it has to stop.
Malfunction in Hyperloop means all passangers are dead.

Watch Thunderf00t rant about hyperloop and read his sources. This project is nothing more than a scam to fetch investors money.
I'm unaware of Musk asking for any particular investment in a Hyperloop project. Most Hyperloop projects are independent parties working on the idea on their own volition. Please correct me if I'm wrong.
That is until Elon can proof he can manufacture the Tube much cheaper than layering the Mag-Lev track.
Is this across the board? I'd imagine the cost estimates would differ depending on where the line would be located - on raised platforms, below ground, or at ground level e.g. a highway divider lane? Or is Hyperloop impractical for pretty much all of the use cases?
IIRC his field is chemistry, yet he explained the batteries vs fuel problem in a wilfully ignorant way.
