Space Elevator Options

[EMac]

While the idea certainly isn't new, the material basis for it is somewhat interesting. I like the graphic...makes it seem like a geosynchronous orbit is nearby versus over 3 times further than the diameter of the earth. I'd like to see the process they'll use to make 26k mile diamond cables.

Very interesting idea for sure and I've wondered the same Emac, how do they know how much transport costs could be with out knowing how to build or deploy one successfully yet.
Another scary thought would be if there are cables stretching from ground to orbit some several hundred miles, if one were to break and begin swinging out of control from the upper end or platform....YIKES! That's one long whippin' nanochain that could do exstensive damage to things from ground level through air space for planes and assumedly, the geo sync sat orbits as well, reaching hundreds of miles in any direction!
