He is aware but according to the alpha document it says 100Pa, which does seem insanely low. All his points seem like very valid concerns, and certainly points that should have had answers before vast sums of money where pumped into the project.

Well, if I am not mistaken, this pressure has been tested on the kind of tube to be used. Also I think it extremely misleading that he compares the total volume of hyperloop and of the NASA vacuum chamber. It makes it feel he does not understand what he is talking about.

It makes almost no difference if the tube is 20 m long or 200 km long. If a small section of the tube can withhold the pressure a long section can as well. And thinking we can't make a low pressure environment in a tube that's a few meters of diameter is... weird.

"All his points" are basically the one point repeated for 26 of the 28 minutes video.
