i'll wait for the workng model
sounds like a semi-permanent addition to earth, if not another piece of space junk. how do you take it down when inevitably it becomes obsolete, or needs repair? if the cable should break --stuff happens-- what happens where and on whom it may fall? what if the space station has to be replaced? do you spool the cable back to earth/sea? what keeps the cable as nicely taut as in the drawing? centrifugal force? who will insure this for, e.g., the aforementioned civil airliner or military jet that crashes into it, or design flaws? isn't japan marked by unsteady geology, of the sort that causes earthquakes?
