   Abstract   
   This article describes an isolated optical setup where the entropy increases   
   when two blackbodies - starting at same temperture - will build up a certain   
   temperature difference. This is done by a special arragement where a kind of   
   filter blocks a    
   different fraction of heat radiation in both directions. Therefore one   
   blackbody will cool off the other will warm up - until a temperature   
   difference will be established. This prove will be done in a qualitativ form.   
   This optical setup violoates the Clausius statement of the 2nd law, an   
   empirically validated postulate of thermodynamics, which states that "Heat can   
   never pass from a colder to a warmer body without some other change, connected   
   therewith, occurring at    
   the same time."    
      
   Setup   
   The optical setup consists of five sheets. There are two blackbodies at the   
   outer borders. In between are two transparent media with a high refractive   
   index. In the middle is a transparent medium with a low refractive index. This   
   sheet acts like a filter    
   which let pass only beams with an angle lower than the critical angle. If   
   these sheets are all parallel (like a "sandwich") no net flux will occur   
   between the black bodies. However if a least one sheet is rotated, a net flux   
   will occur which leads to the    
   temperature difference. It is surprising, you can find this prove here:
