The water gives you more thermal mass so it actually keeps the temp steadier for your beer. If you keep to a regular schedule with the water bottles, you don't get much variation.

I don't have AC, so there's no way I can keep my house at 60 degrees, even if I wanted to live in a walk in cooler like that.

I picked up some of those "dish" tub things from smart and final. They are only a few inches tall, which allow more air flow around the unit. The best part of a true swamp cooler (I grew up with one) is airflow and evaporation. If you put it in too deep of a tub, then the air cannot get in as well. I can drop the temp ~10* or so from just tap water + towel in a shallow tub.

Also, I dont wait for the water to "wick" to the top to start, I dip the towel into the water and pull that up and around the carboy. This gets the cooling to start right away. In Arizona, where its dry.. Doing this once every day or 2 is enough to keep it really cool. My local LHBS had some pump deal with tubes and holes in it, but I think thats a little excessive unless you don't watch it at all.

+1 on that if you're going to do the full swamp cooler. I just use water and ice to cool things, so I want as much contact with water as I can and less contact with air.
