This, I thought. "Maybe guide rails leading up to it"

Not by itself, but maybe in combination with another technology: http://www.popsci.com/technology/article/2010-11/nasa-engine... Whatever you were launching would have to move thro…

Just the simple fact that the Aerotrain was on a track and not in a tube makes all the difference in the world. And I don't get this "look someone proposed something similar before…

I'll go out on a limb here and wager that SpaceX engineers know the Mach value for various permutations of temperature and air density. But I might be wrong...

I'd rather be stuck in my seat for 35 minutes than to travel to an airport, go through security, check-in, waiting and boarding, fly for 90 minutes and then apply all the logistics…

Obvious engineering issues for further investigation. I would just point out that fatal failure mechanisms can be pointed out in any transportation system. The acceptance criterion…

The basic issue the hyperloop overcomes is the energy waste in train transportation, especially at high speeds. This is primarily about aerodynamics, and secondarily about carrying…

Link?

They are taking it out at the ends. Assume a fixed point in the middle, and you have some 1000' of movement at either end. That should be feasible, but the tube needs to be designe…

No you could not. The steel tube will expand and contract as temperatures change. Along most of the route, that longitudinal movement of the tube will be in the 10s and 100s of fee…
