Yeah, I've rigged something like that but it works best in low humidty areas. Too high and that "swamp cooler" won't cut it unless you deal with the excess moisture in the air first. Another thing I don't like about the ice method is the weight though it depends on the road and route speed/condition as to how much impact it could have.

I'm going to stick with the partial windows open as my "plan B", since my tests showed no appreciable difference in that versus windows closed.
