Rumor: High-speed tube travel concept in the works

[BlueStreak]

81. To put this in some perspective

Forget the 4000 MPH nonsense. Let's say they are "just" trying to do 1000 MPH. That means you are covering 4 miles every 15 seconds. What is barely noticeable at 60 MPH is going to feel like a roller coaster ride at 1000 MPH.

And if you start to lose your lunch, there is no lavatory. You are strapped into your seat for the duration.

Going across Kansas, you could build this straight enough, but we're talking a major engineering challenge to make the tubs straight enough to not make everybody sick.

As far a s the view, there wouldn't be any. These are enclosed concrete tubes. The "windows" shown in the graphics, I think, are video panels, so there could be a simulation of what the outside world looks like.

Now think of what it would take to build it straight enough to handle 4000 MPH. This is over a mile every second.
