    I can just imagine the uproar if there were 12 ft diameter Tubes laid across the countryside! More chance of that flying Saucer, they could just borrow one from Area 51?

    And putting them underground just generates a new and different set of problems.

    Its a brave man who says "never". I suspect that much of the hype about the hypertube is all part of the publicity machine of one E. Musk. That said, I do see one genuine possibility for it - the transport of cargo across oceans with the tube laid in a seabed trench.

    I'm not saying one can't be built. What I am saying is its difficulty of construction and impracticality of usage so large as to be little more then an interesting experiment. Can a small one be built and gotten to work as proof of concept - almost certainly - its the "what next" that presents problems.

    Think about this gents: CURVES. If the tube is 12 ft in diameter that is for all practical purposes its gauge. Depending on car length the minimum radius of curvature will be gigantic and the greater the velocity the larger the radius must be.

    As for crossing the Atlantic for example in a trench on the ocean floor - don't forget about the mid-Atlantic ridge where the continental plates are growing away from each other. Gonna need some serious expansion joints there folks.

    These things really would be better off on the Moon, .

    Neat article. A definite proof of concept experiment. Be interesting to follow the progress. I'll be highly surprised if it doesn't work. Its the expansion to practicality I question.

    Something like this on the moon is nothing new. I've been a Sci Fi fan for 60 years. High speed overhead monorails on the moon have been (conceptually) around sine the 50's (and probably the 40's). They are quite a workable concept since (as pware said) the vacuum is free.

    Here's another idea that never made it:

    3. How do you get folks in and out (airlocks)?
    4. What about propulsion (my guess would be linear induction motors)?

    This thing would be great on the moon since no tube would be required. Just make it a very high speed overhead monorail. On earth - more of a publicity stunt I think.

    Yeah, because Elon Musk needs the publicity... The bloke has precedent for doing the unthinkable. What was PayPal/Internet banking before him? Consumer space travel?

    He's the man.

    No need to be pessimistic. He picks apart his own ideas first.

    And he has permission to build a Hyperloop between DC and NY. Even if it doesn't work, what's the harm in trying?
