We've covered Elon Musk's proposed Hyperloop before, including some speculation on what kind of system he might propose. The mass transit concept unveiled today is similar, in some respects, to the evacuated vacuum tube first proposed by the Rand Corporation in 1972, but varies in a number of key areas. It doesn't rely on maintaining a full vacuum, but instead offers an atmosphere roughly 1/6 pressure found on Mars, or equivalent to cruising Earth at 150,000 feet. As expected, the initial LA - SF proposed run would accelerate passengers to trans-sonic velocities, but they wouldn't do it using maglev. Instead, a linear induction motor is used to provide the necessary acceleration and deceleration,... Read more...
