The MIT AeroAstro Centennial Symposium was where Elon Musk answered a question on the Hyperloop. The question was prompted by Elliot Owen, who built a working model of the hyperloop tube and pods (that can be seen below). The question can be seen in the link below, at the 01:02:00 mark:

Here are some key points answered by Elon;

  • He was asked by on whether temperature of the Hyperloop tube would be too high. Elon responded that the diameter of the hyperloop tube would be twice the diameter of the hyperloop pod, to allow air to flow around the pod. You dont want a tight fit.
  • Inner part of the hyperloop tube must be smooth. So you might even have to run a grinder in the inside of the tube to smooth it out.
  • The air-ski’s are spring when the pod is moving through the tube.
  • Expansion of the tube, due to thermal differences, must happen at the terminals. Each pylon must also be allowed to stretch, and you can’t hard constrain it at the pylons.

So much more in the interview and questions, so just watch the whole interview. Below are Elliot Owen’s working model of the hyperloop & presentation.
