I don't know what I want to do after university http://xtubex.in.net/ xtube Gardi says this difference in weight will make it possible for the Hyperloop to be an elevated structure, which will ultimately reduce costs by avoiding the pitfalls of ground-level rail.

It could also lease out farmland and make contracts with communications companies like Google that might be interested in using the structure to expand fiber optic cables.
