With Elon Musk announcing Hyperloop's aplha testing on 12 Aug 2013, super navigation seems to be atleast a possibility.
How will it work? Well, we don’t really know yet because the plans haven’t been released--and the Hyperloop is coming with the usual new technology suspenseful drama that Elon Musk loves--but everyone’s guessing at the basics. We do know that the Hyperloop, if realized, will use pods that are 6.6 feet in diameter. Beyond that there has been plenty of speculation that the Hyperloop will be a pneumatic tube system, but Musk has debunked this in his numerous twitter revelations. Or, a warp-speed train that will use electric magnets to propel capsules through tubes.
According to physics professor Phil Kesten, of Santa Clara University, interviewed by the Silicon Valley Business Journal, Musk’s Hyperloop would have to move at an average speed of 764 miles per hour in order to make it from LA to San Francisco in the allotted time—a speed he suggests wouldn’t be very comfortable for the passengers
