oh ya, and Tom, the post you are referring too concerning that passing air through a swamp cooler is not what was said either. What was said is yes, if you are in a dry climate, the humididty will increase, and that is part of the cooling process of swamp coolers, but there is a level of humidity where swamp coolers will not work anymore, because they will not make the humidity increase anymore either. This is why swamp coolers are not used in areas of high humidity. Even in dry areas, such as West Texas, when it has recently rained but is still very hot (and now humid) swamp coolers do not help to cool in the least bit. They will not make the humidity increase until it rains (or even cause condensation on walls)either. they simply do not cool, and you will be miserable until the humidity drops, unless you do one simple thing: add ice in the water pan.
doing this changes how the swamp cooler cools your house. rather than using humidity to cool your house, it is drawing hot (and humid)air through COOLER TEMPERATURES caused by the ice in the water pan and then taking that cooler water and dispersing it through the cooling pads. Drawing the hotter air through the cooler water lowers the temperature of the air going into your house. It also does not make it too humid in your house to be "bearable" as you put it in that post.
Since this person on this post was thinking of the cheapest way to utilize the cool water from the stream to cool his cabin, I suggested utilizing this same "ice" technique using a swamp cooler instead of spending money on matal radiators. he coudl use this technique with a swamp cooler (and it would be very cheap)because instead of using the ice, simply use the cold water directly from the stream. I know that this would work, because I have done it, many times right after a rain, in El Paso Texas. It does not work quite as well as it would if the air were dry, but it worked a heck of alot better than doing nothing except wait for the humidity to drop back down.
So Tom, please, and I am not trying to put anyone down either, at least do not falsify the claims you say people have made, because noone on this site has made claims that swamp coolers do not add humidity to the air.... They simply said they will only add humidity up to a certain point, and then it will add no more. this is why you do not see swamp coolers banned due to mold growing in people's houses because of condensation. This is also why swamp coolers do not work well in areas of high humidity.
