    1. What happens if it get’s severed and wipes out the eastern sea board?

      • that’s why you put it on an island out in the middle of the ocean.

        duh?

      • I read the RED MARS / BLUE MARS / GREEN MARS book series, and they built a space elevator in the book. Then terrorists took it out. It fell around the entire circumference of Mars 1 1/3 times- because it is that tall, and the planet is spinning below it- and it takes a while for something like that to fall down. The elevator devastated everything in it’s path and left a giant black scar all the way around. On Earth- you could add massive global tsunamis to the mix.

        • Great series. Given how much science Robinson got wrong in those books, however, I’m not sure how if the 1 1/3 part would be accurate, or what it would be for Earth.

          • It would be different for Earth, obviously. Mars is smaller than Earth. In the book, they secured the elevator to the second largest volcano on Mars- which is very close to the equator. The other end was secured to the largest moon orbiting Mars.

            It’s 238,000 miles to our Moon. The circumference of Earth is 25,000 miles. If we built it that way, it would wrap around Earth 9 1/2 times.

            We’d have to anchor to a man-made moon. And we’d have to make sure terrorists didn’t blow the thing up.

          As the mighty Storminator no doubt knows: much depends on the thickness.

      • It’s one of those things which is fantastic in theory but to actually build it (even if technologically capable) would take an act of faith that I can’t see happening. Pretty much ever.
        But if you could do it then oh boy the potential.

        • My understanding is that even if we could ever figure out miles long buckey-tubes to make the thing from, it would still have to be kilometers thick to stand the tensile strain. Not something that would have a ring elevator around it.
