Points to Hardt Hyperloop, and extrapolates to a NY/SF trip. However, Hardt's own FAQ says:
> "The hyperloop is a good alternative to short-distance flights and links up seamlessly with existing modes of transport."
To estimate what "short-distance" means, the Hardt site promotes Amsterdam-Paris. That's about 250 miles, http://www.gcmap.com/dist?P=AMS-CDG .
A NY/SF trip in 4 hours @ 600 mph = 2,400 miles. the great circle distance is 2,574 miles - http://www.gcmap.com/dist?P=SFO-NYC - so the author's times can only be reached with a non-stop, dedicated track between those two cities.
Which is an unrealistic waste of money as it would be a national tax that only really benefits NYC and SF, and not the nation.
The author writes:
> Under FDR’s leadership, the federal government pulled the United States out of the Great Depression, in part, by funding ambitious public works projects, like building our vast interstate highway system.
The interstate highway system was Eisenhower not FDR. https://en.wikipedia.org/wiki/Franklin_D._Roosevelt points out that FDR's expanded the "Reconstruction Finance Corporation, making it a major source of financing for railroads".
It looks like the article contains bad math, bad monetary policy, and bad history. I don't think that's a good way to promote hyperloops.
