   The elevator cars could contain batteries.  A traction climb is so   
   much more efficient than anything else that carrying your power source   
   isn't a big problem.

   Lots of heavy carbon atoms in gasoline.  Perhaps liquified propane.

   He probably steps onto a ship at the geosync point.  Gravity is   
   essentially neutralized there.  Or he might meet a ship at the   
   counterweigt position above geosync.  When that ship lets go, it falls   
   up.

   They call it a skyhook.  you balance it inwards and outwards from   
   geosync.  The outer balance is probably a big rock.

   It's heavy enough that wind will be largely irrelevant.

   Guy wires?  Maybe a few to stabilize the transfer from the loading   
   station to the climb.  For the rest?  It's HANGING.
