You listed evaporative cooler as an example of passive solar. You mentioned Zeer pot in the edit notes and I couldn't figure out your meaning. I removed the reference citing evaporative coolers/swamp coolers as active systems. If you put evaporative cooling back in can you note an example or provide a source?

Not sure what the issue is about the Zeer pot http://en.wikipedia.org/wiki/Zeer_pot or why remove it. It's a simple passive technology but one which has had significant impact. Sod covered roofs kept damp for cooling is another example along the same lines. Put it back in if you think it improves the article - I'm not going to get confrontational about small edits.
