Has anyone else noticed that discussions about rail transport almost always raise a surprising amount of passion? What is with this phenomenon?
Imagine trying to build hundreds of miles of near air-tight chamber. Imagine maintaining vacuum over that distance. Yikes.
I think it is more likely that humanity will migrate to immersive reality than that we will build very many evacuated-chamber-mag-lev-train class super structures.
That said, I would feel substantially more pride in an American firm or government action that produced an effective, sustainable, profitable, pleasant form of mass transit than I would feel if we won the race to mars.
