   Yes. Accelerations, particularly rotational acceleration seems to be the   
   only way to go.

   I would think it should be possible to form a vortex boiler i.e. use a   
   propeller to swirl the heated liquid you're trying to still around the   
   rim of a fixed cylindrical vessel, and pipe the vapour out the central   
   axis and bubble it/blow it into/onto a fixed, cooled liquid/cylindrical   
   surface.   
      
   If you do it right, the distilled liquid will spin around too, and you   
   can collect it without worrying too much about foaming.
