From the video page:
The hyperloop has all the hall marks of wishful thinking of dewey eyed dreamers sold by PR bullshit men who simply dont want to hear engineering reality.
Im currently making a longer video debunking it, but this was just some fun I had this evening simulating the effects of a tube failure on someone in the hyperloop. A tube failure would likely kill everyone in the hyperloop. Getting hit by a 1 bar pressure wave travelling at nearly the speed of sound is fatal. Any who survive would find themselves in a 500km long metal tube in the dark.
If you want to support the next video on the busting the hyperloop!
