It's a concept completely wrong in a lot of details starting from the premises. Their primary objective is to build a tunnel for 100M$ a mile saying that currently a tunnel costs 1B$ a mile. And as I linked in a previous thread London crossrail is already on that price range while boring full-size tunnels for underground trains. So I'm not really sure what they are trying to accomplish here given that the crossrail is already cheaper for tunnels with double the size of the ones than their are trying to build.

The costs quoted are USA costs. Massive infrastructure projects cost more here.

    Indeed, you have a couple of thousand years' worth of plague pits etc. to contend with.

>currently a tunnel costs 1B$ a mile I've always thought that maybe it'd make more sense to just give pickaxes to a bunch of people from a 3rd world country
