I thought that when water evaporated, the temperature of the water cooled and the temp of the air rose.  I also understand that humidity makes air "feel" warmer.
Air has to give up its heat to evaporate the water. The water heats up and becomes a vapor, and the air gives up its heat and gets colder. They exchange heat, basically.

I don't fully comprehend the physics of it myself, but I understand that it has something to do with the "enthalpy of vaporization" and that water has a low enough point that hot air can vaporize it.

As for humidity, yes, it makes you feel hotter but the effect is only pronounced at high levels. Most of the time, the interior humidity in my house is under 20%, so low that my hygrometer can't take accurate measurements below that point. After the evaporative cooler has been running all day, the interior relative humidity is about 45%. It's very pleasant, Probably because the surrounding air is so cold. Extremely high humidity plus hot air is unbearable, but moderate humidity plus cold air is actually pretty nice. It's unusual, though, because most people are used to air conditioning, which removes moisture as it cools.

Did you ever purchase that Russian 308?  Results, comments, updates?

You know, I never did. That part of the budget is going toward a new roof and new windows. And, I suppose, toward the new evaporative cooler! I'm kind of living in a construction zone right now.

Evaporative cooling only is effective in low humidity locations (but I am not sure of the cutoff value).  That is why you do not see it used in much of the northeast, southeast and Texas Gulf coast areas for example.  Air conditioning is wonderful in those areas because it helps to remove the humidity as well as cool the air.  If you sweat a lot when you go outside when it is very hot (e.g. Houston), it is likely that evaporative cooling will not be very effective in your area (very rough guide).  If you don't sweat (e.g. Yuma) it will probably work well.

Yuma is actually pretty humid compared to where I live. The average afternoon relative humidity there is like 45% year-round. It bobbles between 10 and 25% here. :P

Wow, I can almost hear the moisture being sucked from your body, and I'm a couple of thousand miles away.  Maybe that is the cause of contrails.  ;)  We can call it the hypothesis of global contrails - or just anthropogenic contrails if you like.  ;)  But we must be careful, I do not wish your evaporative cooling emissions (deadly H2O) to become too visible (physically and in the public eye).

Just to make you even more jealous… it's a super awesome swamp cooler, not at all like those rusty boxy rattletraps on the roof. When I bought this house, it had one of those, but it was so neglected that it was all rusted out and didn't work The duct connecting it to the rest of the ductwork (in the unconditioned attic, naturally) was made out of ductboard and had mold growing on it. :o So I bought a Bonaire Durango, which is made in Australia, and they REALLY know evaporative cooling there. It has an automatic bleed system so it's not recirculating mineral-laden water forever. And it has a direct-drive fan on a 1/3 HP motor instead of a squirrel cage hooked to a motor with a belt. As a result, it uses only about 200 watts on the low setting, which is plenty sufficient to drop the interior temperature 15-20 degrees. It's astonishingly effective and cheap. I just love it to death.

Even if you don't live in a desert climate, it's often possible to get the benefits of evaporative cooling with a two-stage model, which can often be 125% efficient or more--cooling the air to below the wet-bulb temperature. My one-stage is only 90% efficient and that's all I really need here, but there are probably places west of the Mississippi that could use two-stage units.

Of course Pacific Northwest living requires neither swamp cooler nor air conditioner :)

We had a swamp cooler when we lived in New Mexico.  Really did a good job, but there was always a slow drip right below the vent...

Dude... if you drank.. I'd bring a 6'er the next time I'm in New Mexico and I'd check out your swamp cooler.  The entire concept has dumbfounded me in humid MN...

Perhaps I'll bring some ice cold lemonade.

I would also be willing to do the benediction - probably should allow at least 2 hours of prayer for all of us misguided miscreants, including the final kegger to further Pointedstick's education in the finer aspects of hops and malt.  ;)

Another Topic worth resurrecting with, hopefully, updates from those here...

Reading through these caused me to just now buy on Amazon the following:

Thermos
Air Compressor
Tire Guage

I'm trying to think of an item to contribute to this Topic but nothing is jumping out at me right now. Something I rely upon every day or use a lot.

Maybe these?

https://www.amazon.com/New-Balance-Mens ... _item?th=1

In the fall of 2009 I was starting to have knee pain in both my knees. Shortly afterwards I came across a book on the knees and read it in its entirety that night. One of its recommendations was to buy the best running shoes possible just for walking. I forget how I determined which were the best but the above were what I bought for $100 in November 2009. That was a lot of money for me to spend on any form of shoes but I decided my body was worth it. I practiced several of the other things recommended in the book and the knee pain completely went away, never to come back.

And, I am STILL wearing that SAME pair of shoes even today. The only wear they are showing is that there is a slight tear on the sole of one of them. But that is somewhat deceiving as from May to August I'm either barefoot or in sandals. I don't wear them in inclement weather. And, all other times I'm a nothing on my feet person as much as possible. In other words, they have relatively low mileage on them in spite of the 10+ years I've owned them / been wearing them. And, in this era (or any era?) of constantly changing styles that 10+ years later I was shocked to see that I / you can buy a pair new that looks EXACTLY the same as what I had bought. However, now they sell for $175 rather than the $100 I paid for them!

For any of you who presently have knee pain, here is the highly recommended book...

https://www.amazon.com/dp/1590771249/?c ... _lig_dp_it

And, in the book was this scale...

https://completept.com/stop-hurting-your-knees/

The Huey-Klapper Knee-Point Scale

That scale was an eye opener for me. I answered some questions and it told me how many "knee points" I could expend in a week before asking for knee problems. After answered those questions it told me that in just two nights of basketball a week I was using ALL my allowed knee points for the week, meaning all else was excess. So, I started sitting out a higher proportion of game time.

8-year update: I had to replace my beloved printer last year. It literally fell off a truck during my last move and after that it was never quite the same. It still printed, but the quality wasn't as good and I was unable to fix it. It has been replaced with a 10 year-old HP Laserjet Pro P1606dn, which has been similarly bulletproof so far.

When I started my current job in October 2008 I was given an HP LaserJet printer of indeterminate age. I am STILL using that printer and it's never really had a problem. SOME day it will stop working? The drums are not so cheap, though.

I've had a perfectly good Brother monochrome laser printer for 5 years or so, but I couldn't resist an HP color laser printer for under $300, so I bought it and donated the old printer to the local charity.
