Anyone who’s somewhat interested in mass transportation systems is bound to have looked into the Hyperloop concept at one point or another. One of the things that came up during my research was something called the ‘Kantrowitz limit’.

What is the Kantrowitz limit? I admittedly had never heard of it before, but it seemed like something very important that fortunately had technological solutions. Yet there was something unsatisfying about all the popular resources I could find about it. They all seemed to be very surface level, and when I started looking into it the rabbit hole ended up going a lot deeper than I expected, so I am writing this in the hopes that it might be useful to someone else one day.
