> Elon Musk ... giant subterranean launch tube Hyperloop?

• manigandham 9y ago
  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 https://en.wikipedia.org/wiki/Vactrain

  We should just rename him Tom Swift: "Tom Swift and his Subterranean Launch Tube"
