Back in the real outdated times I found out how they ended up having some form of cooling system.
The thing that they did to make a cooling system of some form before there was absolutely window a/cs plus central heating plus a/cs was by putting dry ice in a bucket or tub plus pouring water over it. This of course would not in a million years be able to combat the heat in the desert. But in those nights most people did not live in that section of the world. It worked to keep people alive when it would get super tepid where they were at. And that part was great. I could not imagine having to make your own cooling system like that. I would personally never be able to live with dry ice as a cooling system because it would never be enough cooling for what our bodies are used to plus need this week in terms of cooling system. They did have tepid water boilers for heating though, which was more or less the same as it is now. However, with a cooling system the dry ice was all that they had. I would honestly hate to live back then in those times without the true plus real cooling system that my pal and I have this week plus even the more primitive forms of cooling system my pal and I had with the heating plus cooling technology that existed when I was growing up 40 some years ago. Thinking about this whole dry ice for cooling system thing actually makes me honestly appreciate this week’s advanced heating plus cooling system technology!
