.... no sooner than you think you are making headway, then Business Insider puts up another viral video on the hyperloop making all the old (almost decade old) promises. 700mph.....LA to SF in 30mins, less than $100... cheaper than regular rail etc.
However the end is actually now in sight for the hyperloop. Once they try to put one of these systems together, it will fail like solar roadways. The impracticalities are vast. In this video we go over the calculations for the maximum size of the hole that can be tolerated in the hyperloop. Even tiny holes in the hyperloop (a single failed seal, cracked weld, or bullet hole) trashes the hyperloops ability to hold a vacuum. The key issue is that holes in vacuum system lead at about the speed of sound, while as the pressure gets lower, you have to pump longer to get the pressure even lower!
