Hyperloop

I've seen several articles on the Hyperloop in the past few days, and it does look pretty interesting.  If it turns out to be less expensive than a train, I don't see why we shouldn't start building these things.  I love to drive, but honestly, sometimes it's just easier not to, and since taking a plane or a train is a pain, the idea of travelling in a high-tech pneumatic tube sounds like a breath of fresh air.  We'll have to see if this actually happens, if it does, it could do wonders.
