I have to think more on that, for my other questions, but, wouldn't that heavy weight out in space be, well ? weightless ?
I should have said "large Mass" instead of large weight.
you're confusing weight with mass.
as much as i love the idea of the space elevator, i wouldn't expect anyone to build one for another hundred years, even if the nanotube technology is available now. It's rather expensive, sort of dangerous (imagine a long rope falling from the sky encircling the globe and leaving a wake of destruction around it's circumference. i read too much sci-fi i guess), and also complicated. On the plus side it would make getting into and out of orbit easy as pie.
