@DarkRaven4561 Pressure tube transportation for small objects has been amazingly successful for more than a century. It's only natural people would think of expanding it to human sized cargo. It's just a shame the engineering is so tricky. It might still work one day with appropriate materials and in the right geography.

That's jaw dropping with the thermal expansion stuff. Did he buy his PhD? I worked with people getting optics PhDs and this kind of thing would have been second nature to them. I know we all have the occasional brain fart but this goes way beyond that.

If you're not going to go full vacuum, that's probably not too unreasonable. I think it would be interesting to see if this could be done with the vehicles being entirely unpowered but using pressure differentials to drive them. You'd need some kind of lock system on the tubes though, I think.

@link7417 True but I think there might be some effects worth investigating that might mitigate the issue a bit. Travelling waves, "regenerative braking" type energy preservation and similar. Possibly not worthwhile though and the repeated mechanical stresses would take their own toll (though planes fly thousands of times).
