    Just heard Professor Quine of York University on CBC on his concept of creating a 20 Km structure to act as a space elevator. They have done some physical scale modeling :-)

      I first read of this concept in a sci-fi about Mars - a Kim Stanley Robinson epic I think? It has a huge setup cost but very little to run. If you have product going down the stack it lifts stuff going up. That regenerative aspect is clever. But you still get benefits without that.

      Also, as the sci-fi illustrated, it'll make one heck of a mess if it comes down. The structural material qualities are rather stringent. It is the old battle between weight vs. strength, in compression and tension, but with flexibility in addition. I like the idea of inflatable components which lighten the loads.

      I'd be unsure if you'd get people to ride it initially though. Mind you, an exit in a gliding/flyable craft is do-able.

      Cheers, Mike.

        Arthur C. Clark wrote a book called 'Foundations in Paradise' which I think is the first reference to a space elevator.. Their paper actually references this book:-)

        There all plenty of adventurous people to try it out initially.. People with some disposable cash (about thirty million US) can get a ride to the space station aboard a Soyuz space craft.

          Ah, the ultimate bungee jump. Literally. It'd be the last thing you'd do. :-O

            Actually I would like to take a leak off the thing ;-)

              Yeah .........

              Definitely a Bucket List item.
