This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

A modern home ACs can only cool about 20f below the outside temperature. 50c to 35c is 27 degrees so that's pretty damn good for a fancy unpowered swamp cooler
What’s your source for this? It routinely gets over 100 here and buildings aren’t 80 degrees inside.
pretty sure 50c to 35c is 15 degrees
I wonder how he got his number, it makes no sense.
EDIT: oh, he just randomly mixed °C and °F, because why not...
Fucking Americans
Yeah, the thing is the "unpowered" part. Look how much energy an AC chugs to achieve that cooling. This tower uses wind power to do it's thing.
The AC is also small compared to a literal building with a sewer underneath and doesn't require a windy day. Trade offs
ok, but the cost of building a quanat is still pretty high and is not trivial to achieve.
Can't have water flowing everywhere in a country for this to work.
10 degrees is incredible though.
These days in Yazd the average warmest temperature in July is 40 degrees, so if what you're saying is correct they'd be able to cool it down to a liveable 30 degrees even in the warmest part of the day. And at night temperatures still dip to 26, so the indoors temperature probably wouldn't quite reach 40 even without this system. So it might make the difference between 40 degrees outdoors and high 20s indoors, which is fantastic.
Would be interesting to know if average temperatures got up to 40 in the summer around the time they were built as well, or if average temperatures in the region have been rising.
Oh man, I can't believe ancient physics powered cooking techniques weren't as efficient as the electrically powered cooling that we have today, those idiots
Might not be a shivering 16 Celsius inside, but if it's the difference between dead and alive then it's probably good enough.
What a bunch of idiots! They should've just installed AC units.
I hope that was a sarcasm, if so, add /s.
It's the internet, you never know. In person, by how the person behaves, you know if he's being sarcastic or not. On the internet, not so much. It's just text and I've seen people who were quite serious.
I think at some point the /s isn't needed
