You'd need to accelerate at 68 G's[0] (foreward for the first four minutes, backward for the last four). Not neccesarily unsurvivable, but your passengers (and most cargo) are likely to be unpleasantly pastelike.
We should probably treat it more like commercial air travel than compressive-structure elevator rides.

- ridgeguy 8y agoBrief search didn't get me anything about longest ride on a centrifuge, which I guess would be the only way to test G-tolerance over extended periods. Where 'extended periods' means > an hour. Any pointers to 6 Gs as being tolerable, for how long? Tnx.
- perl4ever 8y agoDon't know, I was quoting a figure for 10 minutes. 6 gs for 10 minutes will get you to 35 km/s, which I believe exceeds any rocket launches so far.
- jjeaff 8y agoI don't think 68 Gs is survivable at all. At least not for more than a fraction of a second. 46 Gs for a few seconds is the most a human has survived that we know of. 10 Gs for 1 minute is lethal.
