Video promises a future of high-speed tube travel

It's Earth Day, which may account for today's interest in evacuated tube travel. Rocketing along an airless, frictionless, magnet track, is no jokes and the benefits, applications and energy savings are seemingly unbelievable. The tube tracks are far cheaper to build than high speed rail or freeways. Capsules, carrying up to six people and their luggage, would travel at speeds of up to 4,000 miles per hour (more than five times faster than a bullet) making the run from New York to Beijing a mere two hour journey. The trip from New York to L.A. would be an easy 45 minute commute. If you're imagining your face skin rippling back towards your ears, relax. Passengers would only experience 1G of force.
