Now we just need those inertial dampeners!

What a way to spill your cocktail…

I wouldn’t want to travel in that, but it would be a good way to get shit into orbit without using rockets.

Railgun that shit up

Your move hyperloop.
So what’s the limit of the human body? That’s more than a couple g.
krashmo@lemmy.world 2 months ago
I don’t know but it seems like the simple answer is to just not accelerate that fast. I doubt this was an attempt to imply that we should do this regularly. It’s just a test to show what the technology is capable of. There’s no real benefit to accelerating to that speed that quickly vs doing it over 30 seconds or longer.

You can absolutely accelerate this fast if there are no people on board. China probably wants safe autonomous cargo trains at some point.

There are non-transportation uses for it. Namely for weapons.

Definitely a “look what I can do” test and not a practical example of how the trams in Beijing will travel between stops. Though it would reduce trip time!

20-40 Gs for horizontal force.

Squishy.

How far did it travel in that 2 seconds?
Royy@lemmy.world 2 months ago
If acceleration were constant (and my math is right), it would be 194m. We can assume due to air resistance being proportional to the square of the speed that acceleration will be more initially and less later, so realistically it will be >194m

Is this like those amusement park rides that use magnets to accelerate really fast?
cogitase@lemmy.dbzer0.com 2 months ago
7.2 g acceleration. You could strap a human on there and they’d survive the acceleration phase.

For an untrained person this night well be lethal.

Only 2 seconds of horizontal g? Not unless they weren’t securely against the seat and died due to blunt force trauma from being slammed into the seat back.
Beacon@fedia.io 2 months ago
Yeah this link says most people can only take 4 to 6 g, but fighter pilots can take up to 9.

That’s an expensive way to look inside your own skull.
