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...

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.
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
