Wonder how fast the 'elevator cart' would be able to move. Considering that it takes a rocket several days to reach the moon.

- ed312 7y agoMost of the time the rocket isn't firing - you have a few minutes of burn to change your delta v, then you just gotta sit and wait before decelerating into orbit (or landing). Assuming the cart was attached to a powered cable you could in theory constantly accelerate until half way, then constantly decelerate. Possibly this would allow you to make the trip faster (unless you had humans on board, then you're probably stuck with short accelerating bursts).
- brians 7y agoI'm pretty sure humans can take 1 g continuous.
- pmontra 7y agoI'm not sure if the cable can take it: 1 g yields pretty large speeds quickly. Somebody already made the math at [1] [1] https://space.stackexchange.com/questions/840/how-fast-will-1g-get-you-there/5016#5016 https://space.stackexchange.com/questions/840/how-fast-will-...
