Hyperloop One to Shut Down After Failing to Reinvent Transit
(www.bloomberg.com)
This is a most excellent place for technology news and articles.
And even maglev is barely done because it's so expensive to build. Hyperloop is wrapping that same maglev train into a tube that should maintain a vacuum for kms on end, and pretty much every failure mode would end up being genuinely catastrophic.
Plus you would have to armor the whole thing and spend a bunch on security because one guy with a .50 rifle or some explosives could destroy a whole section and close the whole thing by punching one hole in it.
Haha, yeah. Remember the chaos when militia guys started shooting at transformers in substations? Every hick with a gun would be shooting at it just to shut it down.
