Ummm,,,,,, in the desert.

The stark reality of evaporative coolers is that they work best in the
very places that typically don't have a lot of water.

In places where evaporative coolers work well, some nicer houses even
have them integrated into the central heating/cooling system.
Evaporative coolers also have the side-effect of dumping a lot of
humidity into the air, which, if you have a luxury home with a lot of
fancy woodwork, part of the warranty is that it isn't valid if you don't
take precautions to protect the interior of the home from very-high and
very-low humidity--because the pretty woodwork will all warp and crack.

If retailers don't sell them where you live, then you probably live
where they don't work well.

If you live in a humid environment, all a swamp cooler is going to do is
make mildew grow on everything in the room.

Actually it's pretty surprising that in the desert the relative humidity often runs to 24% which is humid as hell. Inside your home it's probably around 12%.

Yeah, Coolerators are bad enough in Texas but useless in
Wisconsin or (as Frank said) Ohio.

up something like that for our sunny patio, for next summer.

I've seen them used in Thailand and Singapore. Singapore has an
average temperature of 82.5(F), 166 days of rainfall and an average
humidity of 80%. Thailand has an average humidity of 79.9%, average
annual temperature is 89.6(F) and averages 130 days of rain (average
whole country).

Quite a lot of open air type of places have them and my experience was
that it made it feel cooler, but I don't know whether it actually
lowers the temperature appreciable.

The first ones of these I saw was a ring of, maybe, 1/4" tubing
mounted on the face of a 24" fan, similar to
https://www.amazon.com/DecoBREEZE-Ou.../dp/B002COJB3Y
A piece of 1/4" copper tubing and one could make his own at least well
enough to see whether they were practical.

My wife has a evaporator type of room air con (swamp cooler) and it
blows cool air... or at least it feels cool, even during a downpour.

Re make your own. The first ones I saw were simply a tube ring with
small holes drilled in inner diameter of the tubing aimed straight
across the face of the fan. No nozzles as in the Amazon version.

Um... "humid as hell" is over 70%. We see that routinely.
