Comment on Chinese Maglev test vehicle sets world record, accelerating from 0 to 318 MPH in 2 seconds

It’s completely not practical.
7Gs is also not categorically lethal hut average people will start to pass out around 4Gs if the acceleration is vertical, and 9 is about the upper limit that trained, fit Air Force pilots can experience without losing consciousness.
So 7 is nothing to sneeze at even under ideal conditions.

Okay, again, I agree this is not in the slightest practical, but also, again, a train accelerating is not vertical g, horizontal g tolerance is much, much higher than vertical g tolerance, especially “eyeballs in” and it increases greatly the less time it is for. Some early experiments showed untrained people could handle around 20g for less than 10 seconds. Also blunt force risks could be mediated almost completely by ramping the acceleration slowly, first reminding people to brace, then gently forcing them back in their seats. Again, ludicrous, nothing designed for comfort of human passengers is ever going to be designed to accelerate anywhere near that quickly and it’s completely unnecessary anyways.
