Outdoor RH is variable here, and usually enough below 100% to get a little cooling
the humidified air simply blows away outdoors, its not really an issue. Coolth is harvested from the body of water left behind.
this is immaterial because we dont bring the damp air in.
wrong conclusion due to wrong setup in mind. You dont get much, but added to a system like the fanned method it makes a useful additional contribution.
its just one more incarnation of evaporative cooling

You misunderstand - that's exactly the situation in the calculations. I'm assuming the evaporated vater vapour is released outdoors.
And I haven't done so above.
Actually, it's exactly your setup, if you follow the calculation.
Actually, near as damn it, nothing.
It doesn't.
A fan pointing at you will work best of all, in the absence of real aircon.
So true, I have a portable air-conditioner in my room, I used to set the temperature to 18C-it was cool and comfortable and I never used to sweat, now I set it at 23C, it is a little bit warmer but it is still bearable and comfortable whilst the other rooms which are at 23C are not comfortable because they are very humid. Excuse me if I seem dumb but this is what I have found out myself as a 14 year old.
Yes, that makes sense. Only in very dry atmospheres would you get sufficiently rapid evaporation. The temperature falls he talked about did seem high, but he did seem to know what he was about. Pity that. Seemed like a good solution.

I want one of those sleep gas pens, then!

I don't have that much of a problem
Aha - now you're talking
But I'd be advertising to people who already know me :-)
Fill em with water, it seeps through the pottery and evaporates from the outside surface. In so doing consumes the latent heat of vaporisation required from the pot and thus reduces its temperature - the water in it and any cans floating in it.
put bottles in wet socks and hang them out of the car window.
I used to see every bakkie in S Africa equipped with these..
You are spot on. In winter I need to have rooms at 21C before its T-shirt time..in summer I am happy at 18 degrees.
In UK summer, if the air is reasonably dry, you get the best cooling under tree canopies. Natures air conditioners.
