My points was that large computer rooms and buildings are not cooled by the same technology that cools the typical American home, and at least some of the principles of evaporative cooling and the heat capacity of water are used in many of them.
At least 2 of the Harrah's NV locations have backup evaporative cooling systems for their computer rooms which can be more easily driven by emergency power than their normal cooling systems.

But that still doesn't address the difference between home swampers and A/C's. You make an "80% efficiency" claim of evaporative coolers vs. heat pumps, but fail to acknowledge the far greater usefulness of A/C.
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.
