A magnetic levitation vacuum tube can transport you around the world in just six hours. Did a cartoon predict our future this whole time?
The worst part of traveling is getting stuck on a massively lengthy flight, especially if you’re in a window seat next to a crying baby, a snorer, or that anxious passenger who won’t stop shaking his nervous leg. With this Evacuated Tube Transport (ETT) concept, the fuss of long distance travel could be eliminated altogether by significantly reducing travel time during this incredibly high speed transportation tube.
The short version of the ETT story is as follows: put a superconducting maglev train in evacuated tubes, then accelerate using linear electric motors until the design velocity is attained. As the motors are integrated into the evacuated tubes, the conveyance capsules which travel in the tube need have no moving or electrically activated parts – passive superconductors allow the capsules to float in the tube, while eddy currents induced in conducting materials drive the capsules. Efficiency of such a system would be high, as the electric energy required to accelerate a capsule could largely be recaptured as it slows.
