I love all of these renderings showing transparent tubes. The tubes probably aren't going to be transparent. I'm not even sure who would want to look outside at that speed (besides me), so close to the ground.

I took this to mean that there would be windows.I agree about not wanting to look outside, though. I've travelled on the shinkansen in Japan (which go ~ 1/3 of the speed that the hyperloop is planned at) and it was really hard to look out of the windows for any length of time.
(I'm not sure I'm joking)

I traveled in the ICE in Germany, also about similar speeds at the shinkansen, and some of the views are breath taking, and some views gave me a migraine.
I suppose they could cut holes in them in the image, but that's just like showing them as transparent.
