The hyperloop calculations are way off. the longer the tube, the thicker it has to be to support itself. Instead, "aerial airstrip" on slide 21 would make a ton of sense. Move airports from the ground to above the clouds (3km up in the air?). Advantages: 1) 10-15% less fuel consumption (after take-offs you are already at 3km altitude) 2) much less noise for the surroundings 3) less subject to bad weather conditions. etc.
