      Yes, this idea has been used, but my memory is too fuzzy for a clear   
   cite.   
      
      ISTR it involved the crew of a ship being kidnapped and put into such   
   a gizmo on a (our?) moon, but the idea was to convince them they were   
   being detained on a planet (Earth?), so that Secret Information could be   
   gotten out of them non-destructively. IASTR it involved Soviets and   
   Americans.   
      
      Best I can do; maybe it's enough to prod somebody else's memory.
