My thought is that is a kind of train in a mostly vacuum sealed tube to eliminate friction and maintain stability. That's the only way I see they'd be able to maintain the 900 mph speeds they want to attain safely. You'd think that something like this would be tried first on the east coast though, where the ground is much more stable. California just seems too unstable to develop such a system having multiple major fault lines running through it.
a vacuum along a thousand miles of tubing? unlikely. i think more likely he found a way to move air through the tube at that speed with reasonable safety, then you just drop a pod into the stream and whoof! off you go.
next year i think blue needs to run a bluesnews fantasy league!
