Those don't do shit if the air is humid already
working well enough in Doha and Doha is a very humid city

Not really, the data shows it's fairly dry most of the time, especially during jun-jul with RH going as low as 40% and as high as 75%. Compare that to something like Istanbul or Pattaya where it practically never goes below 75% and such system would just spray water directly onto the ground where it's going to stay as a puddle and never dry up.
The outdoor air conditioner in Doha doesn’t spray water, just cold air
Pretty sure those are just normal misting fans in the first comment that I've responded to. Those just dump water in the air which causes perceived coolness as evaporation causes significant cooling.
To blow "just cold air", the only remaining options are either chemical, which is definitely not renewable at all, or by placing a cold radiator behind a fan. But then the question comes up where are you gonna take the coldness from? This is basically the same question as where are you going to dump the heat to? Surely, you can hook up an AC and use geothermal shenanigans to dump it under the ground, but that'd still be massively wasteful and the only way to get the ridiculous amount of energy for it at scale is from non-renewables, which would hasten the climate change even further.
I see what's happening. I posted two different videos one of Doha and one of Madinah. Doha is one the Arabian Gulf and has a hot humid climate, Madinah is up the mountains of Hejaz and has a hot dry climate.
