 I still don't see an effective way to arrange a residential cooling 
 system based on the evaporation of water. 
  
 I don't think you can concentrate and deliver a substantial amount of 
 heat to a surface you can cool via evaporation.  Evaporative cooling 
 would be effective if the heat inside a house could be brought to an 
 out-door device who's surface temperature is well above boiling and 
 the application of water would result in evaporative cooling.

 So what you're saying is to mistify the air circulating in a house in 
 order to cool it.  I don't think that would work once you've saturated 
 the air (ie humidity > 75%) not to mention the effects of saturated 
 air on items in the house, the wood, the machinery, etc. 
  
 I think only the roof makes a workable item to cool with a water 
 cooling.  It's designed to get wet, to collect runoff, and gets very 
 hot in the summer, and cooling it can lead to reduction in cooling 
 requirements of the house. 
  
 The only thing that makes more sense is a temporary tarp or canopy to 
 cover the roof during the summer (to be taken down during nasty 
 weather, storms, etc).
