re Robert Grants understanding
"How the geostationary satellite would possibly bear the weight of the elevator. Even when you find a tether strong enough, you've still got to:"
"Keeping the satellite in place (a) is definitely the more complex of the problems, as what's to stop it plummeting to Earth under the weight of both ends of the tether?"
fill a bucket with water, take hold of its handle, and swing it around in a circle; what happens to the water?
the cable dosnt need to be strong just to support the elevator, it needs to be strong to hold the satellite, and keep it from dissapearing into space.
my understanding of it is that its not quite a geostationary satellite, but just a little further out, like that bucket on the end of your arm.
