Arthur C. Clarke often wrote about space elevators. Space elevators (in theory) are mechanical connections between the surface of the Earth and synchronous satellites. This concept is pure science fiction – or is it? Great article in Wired that discusses some advances to develop the technology. Even with these developments, I doubt that this will happen in my lifetime.
