Traveling by Tube Instead of Airplane?

Summary of Article: A new company, ET3, is planning a new transportation system, called an Evacuated Tube Transit. It is a tube that goes at high speed and uses magnetic levitation. It can travel 4,000 miles/hour, seat 6 and has room for baggage. It could go from NY to LA in 45 minutes (it currently takes 5+ hours) or from New York to China in 2 hours. They would be set up like freeways and to people traveling inside, would feel like being in a car on a freeway. Initially, they would be used to transport cargo.
