I wonder if they've fixed the basic engineering errors from the first proposal: http://www.leancrew.com/all-this/2013/08/hyperloop/ http://www.leancrew.com/all-this/2013/08/hyperloop/ > Neither of these is possible for the Hyperloop because the high speed of the capsule zooming along inside it means the pipe curves have to be very gentle. How, I wondered, is Musk going to solve the thermal expansion problem? > The answer turned out to be simple: he didn’t. There’s some hand waving and, possibly, a complete misunderstanding of how thermal expansion acts, but no actual solution. The rest of the article is a deep dive into the problems with the earlier Hyperloop proposal.
