I was wondering if there were updates about this myself. There's been lots of work talked about researching the fluid / heat & weight dynamics, but very little about maintaining the vacuum - which seems to me a more fundamental problem here...
- simias 9y agoI'm also interested to know what's the plan in case of a brutal rupture of the tunnel. A wall of air rushing through the pipe to meet a car traveling at supersonic speed doesn't sound very pleasant. Maybe they just plan to make the pipe sturdy enough that it wouldn't be a practical concern?
