That demo is unrealistic. The entire end of the tube isn't going to open all at once. Instead, any realistic leak would be pretty small in comparison.

- UnoriginalGuy 10y agoI don't understand why a tube section couldn't come away? What if a bomb went off, a truck hit a support beam, or an earthquake caused a section to topple over... I don't think it is unrealistic at all.

- Retric 10y agoIt's an elevated track so it really could be designed to deal with that kind of break. Water, Oil, and Gas pipelines for example have long dealt with those issues without breaking when designed correctly.
- brianwawok 10y agoHow do oil pipes do this? Automatic cutoffs every mile?
- Retric 10y agoThere are a wide range of solutions: https://sfwater.org/modules/showdocument.aspx?documentid=5770 https://sfwater.org/modules/showdocument.aspx?documentid=577... http://www.pbs.org/wgbh/amex/pipeline/peopleevents/e_quakes.html http://www.pbs.org/wgbh/amex/pipeline/peopleevents/e_quakes.... Sliders https://www.quora.com/Why-do-oil-pipelines-that-transfer-oil-long-distances-run-in-a-zigzag-manner https://www.quora.com/Why-do-oil-pipelines-that-transfer-oil... Now doing this without bending the long pipe is going to be harder, but you really could design this thing so riders don't notice a magnitude 9 earthquake. PS: In the end you get into cost benefit designing it to survive an aircraft impact is probably not worth it let alone a nuke, but predictable earthquakes are not that hard.
