   1. A rotating space station is more complicated and thus more expensive than   
   a non-rotating.   
      
   2. One of the primary reasons for having a space station is microgravity   
   research.   
      
   3. To create any useful artificial gravity, the space station should either   
   be prohibitively large or employ prohibitively fast rotation periods. If the   
   station is 100 meters across, it should rotate once in 14 seconds to create   
   1 g, which would probably cause severe nausea. A station 1 kilometer across   
   should have a period of 45 seconds to create 1 g.
