It is astounding how the 800 km/h maglev train test in China imitates what has been shown in science-fiction films. The fact that a train weighing more than a ton moves from 0 to 100 km/h in under 0.7 seconds is truly crazy! It is even faster than a Formula 1 car. However, it is quite sad that common people will distant to be using this technology for the near future because of g-forces. But, in any case, it is great to know how the absence of friction can lead to such incredible know-how.
