Hi,
Here is another approach that is closely related to your approach for helping out your AC from Chad. I just put it up on BIS this morning: Increasing AC Efficiency Using Evaporative Cooling of Condenser Coil

Also got an email from a person whose AC unit was sitting in the sun. After some experimentation with various kinds of shading devices he settled on taking sheet of plywood, and cutting a circular hole that matches the diameter of the fan discharge. He just places the plywood over the AC outside unit with some supports -- it shades the unit from direct sun. No doubt, not as effective as the water cooling, but probably helps a bit and is very simple.

I was kind of surprised at the mineral levels for rain water -- it picks these minerals up from the air on the way down? Or?
