Making Venus habitable: Start by siphoning off the atmosphere.
   Use self-replicating nano swarms that break apart the unwanted
   bits off of the molecular chains and carry them out of the
   atmosphere towards the sun. Mind you, this would require some
   severely efficient energy storage - perhaps something akin to a
   complicated electron maze... although at this point, we should
   be FAR BEYOND electrons and being able to harness the energies
   inbetween the "electron shells" and THEN harvesting the released
   ions as well. Total science fiction, but then again, so is most
   of theoretical physics :P*** -Kenneth Udut
