The Hyperloop is a rehashed vacuum-train idea originally from the 1800s (reduce air and rolling resistance as the primary forces counteracting speed). [1] A launch tube would be very different, if for no other reason then the fact that you need to actually jettison the payload at one end at high speed. 1. https://en.wikipedia.org/wiki/Vactrain |
