Still More on Space Elevators

Not Science Fiction: An Elevator to Space. Not a whole lot of technical detail but good read. It is interesting to see alternatives to current space technologies being explored."
Not Science Fiction: An Elevator to Space
meh.
Clarke's Fountains of Paradise is a wonderful book. It presents the basic physical problems of a space elevator and some ways to solve them (and it has a great plot too).
Right now, as Clarke envisioned, carbon nanotubes are the only engineering material that could be used to make this elevator. The basic technological question is whether we will ever be able to make cheap and long nanotubes. Despite the enthusiasm for a space elevator in the NYT article, we really have no idea how to do that. And any cost estimates like "$6 billion" are very immature without that kind of detail.
I've put in a request... hopefully our headlines will be added as a slashbox here soon.
No.
Orbital paths are dictated by velocity and altitude.
Any objects,regardless of differances in mass, at a given velocity and altitude will orbit along the same path.
