-> FWIW: we've discussed your theory as well as the other one in which the 
-> station's belly always points to the earth...  
  
Another thing... Think of the solar panels on the space station. For 
good efficiency, they always have to aim at the sun. But if the station 
were rotating, the panels would have to be on fancy pivots so as to 
turn to keep facing the sun. They aren't, so they don't, so it isn't. 
  
Maybe it rotates once per year, to keep the panels aligned, but that's 
very different from once every 90 minutes!
