http://en.wikipedia.org/wiki/Hyperloop
The Hyperloop is a conceptual high-speed transportation system put forward by entrepreneur Elon Musk,[1][2] incorporating reduced-pressure tubes in which pressurized capsules ride on a cushion of air that is driven by a combination of linear induction motors and air compressors.[3]
The conceptual route runs from the Los Angeles region to the San Francisco Bay Area, paralleling the Interstate 5 corridor for most of its length, with an expected journey time of 35 minutes, meaning that passengers would traverse the 354-mile (570 km) route at an average speed of around 598 mph (962 km/h), with a top speed of 760 mph (1,220 km/h).
EXTRAORDINARY! The sound barrier is at 768 MPH +/- depending on altitude. This would be fun if it were privatley funded and managed. But I am sure my tax dollars will somehow be used to vett this and eventually be wasted. California can't do this. It needs to be tried in some other country first. Innovation in America is expensive and all but dead.
