Hyper tube would transport you from Houston to San Antonio at 700 MPH

HOUSTON -- A 21-minute trip from Houston to San Antonio is a few miles closer to reality. A proposed project that would connect Austin, Dallas, Houston, Laredo, and San Antonio via a futuristic pod-and-tube system is now one of four U.S. finalists in a global transportation contest.

Once in San Antonio, getting to Austin would take another eight minutes for Houston travelers. The trip from Houston to Dallas, not including the time for layovers, would take 48 minutes.
