Speculation on the Hyperloop
There has been a bit of buzz in the last couple of weeks about a conceptual new type of transport that Elon Musk has developed called the ‘Hyperloop’. While he hasn’t shared specific details, he has mentioned the concept in a few recent interviews e.g. here and here.
I find this exciting because I’ve been thinking about new types of high speed transport for a while now. I don’t think we’ve solved the 'moving people around’ problem as well as we may have predicted 50 years ago (alas still no Star Trek transporters).
