Wired: Tesla Motors CEO Elon Musk says a "Hyperloop" network of pneumatic tubes could transport travelers between NYC and LA in 45 minutes.
As crazy as it sounds, Musk is merely updating an idea that's been around since the early 1900s, and at least one company is working on a functional prototype. But according to Wired sources, his involvement won't be nearly as hands-on as Musk's other endeavors at Tesla Motors and SpaceX.
The engineering behind the Hyperloop is similar to the old-school pneumatic tube systems used by banks to suck your deposit to the teller at the drive-through. But naturally, it's more complicated than that.
