My reference to computer labs was to illustrate the limited usefulness of the type of cooler in your house. You can't use a pure swamp cooler in a lab environment because a lab requires greater operational range than they provide. Similarly, for most people, their home cooling desires also require a greater operational range, like being able to operate when there's greater than 30% ambient humidity. Just because industrial grade coolers leverage evaporative cooling as part of the system, doesn't make your swampcooler similar enough to my air conditioner to suddenly justify the invalid comparison from earlier between the two. Now we're talking about apples, oranges, and bowling balls.

For the end goal of cooling a home to a reasonable level in our climate, I still contend they are not apples and oranges. The are Granny Smiths and Pippins. They each have additional pros and cons, but for that basic role, they are both very capable in climates such as ours.
Current humidity according to weather.com is 30% and yet my house with undersized swamp cooler is 72, 8 degrees below exterior, and perceived temp is probably closer to 70 or lower due to air movement, AKA wind chill.
I don't know if you have read the stuff from the CA study of the 2 stage evaporative units, but it is very enlightening.
Swamp coolers are not ideal for all conditions, but neither are compressor based AC units. I never claimed swamp coolers were a one for one replacement for AC in all environments.
I still contend that in this region, you can save in the neighborhood of 80% on your cooling costs by using evaporative cooling and still have a comfortable home.
