My attempt at a swamp cooler last year was pretty useless. I did the two bucket method from apropropedia. http://www.appropedia.org/Burning_Man_Evaporative_Cooler
One major problem was that the water wasn't rising in to the wicking filter of its own accord. Is that what people are using the pumps for? To keep the filter constantly wet? Rather than use a wicking filter, has anyone tried using a mister? Here's one that looks decent: http://www.canopycool.com/ Though I'm guessing it would be much cheaper to find a suitable pump and rig that up myself.
