Ever since people in covered wagons took six months to make it from the East Coast to California, they’ve been trying to make the journey a bit shorter. By train, the schedule is about 40 hours. Today, by passenger jet, it takes about four hours.

Now, a company named ET3 predicts that within a few decades, a way to do it by an underground vacuum tube system will take you coast-to-coast in just 3/4 of an hour! ET3 calls it the Evacuated Tube Transport, a 4,000 MPH train that’s blasted through by magnetic levitation.

The whole concept sounds like something a magician would conjure in a stage act, or a super big one of those old department store message suction tubes. The ET passenger system would be made up of a line of six-person capsules in rows within the tunnel vehicle.

Even more ambitious, when the tubes can be constructed to extend under oceans, a trip from California to China could happen in just two hours, and even less from New York to London! When it becomes an entire world network of tubes, it will certainly revolutionize long-distance transportation, as well as shipping, as never before.

Can you imagine telling your family you’re tubing to Beijing for Sunday brunch, and will be back home in time for dinner? And then tubing for a midnight snack in London?
