I am curious, does an expansion joint not help here? Is it impossible to make an expansion joint that deals with the kinds of pressure involved?

  Expansion joint is likely the way to do it, but I'm not aware of vacuum expansion joints of that size. Even if it's possible, it sounds very expensive to make and to maintain. Just like everything in this project. That's the thing about Hyperloop. It's not technologically impossible. It's just not economically viable.

    > That's the thing about Hyperloop. It's not technologically impossible. It's just not economically viable. That's probably why this is an idea from Elon, not from the industry. The guy has a habit of forcing the market itself to accept beneficial ideas, and in the process they become viable.
