I'm glad I started following SourceFed on YouTube. In one of today's videos, they explore the proposal and possibility of Pneumatic tubes to build super-fast trains connecting distant locations. Like, NY to LA in 45 min. The trains would travel at over 4000 mph, and would be an awesome alternative to plane travel. I mean, imagine building an above-ground vactrain, and putting solar panels along the top of the tube all the way across to power it.
I want this to happen. I want this to happen to the point that I would consider voting for Romney if a promise to build this within four years was part of his stated policy. (And congress explicitly had his back.)
