I love passive systems. The more passive the better.

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
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.
Might not be a shivering 16 Celsius inside, but if it’s the difference between dead and alive then it’s probably good enough.
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
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
Lotta old Victorian homes and factories from that Era did the same thing (without water obviously just a big tower to catch the wind). More like an attic fan than an AC in those cases, still a pretty clever way to move air without electricity. Always impressed by how clever people were back in the old times
Not really mentioned in the picture but Qanats are basically underground aquaducts, bringing water from nearby mountains to the cities. They can be up to 70km long. We went into one when I visited Iran.
I think that the Eastgate Mall in Zimbabwe makes usage of a similar principle, but their inspiration came from Termite Mounds https://www.youtube.com/watch?v=qP8DSdfoiZw
I gotta wonder if the same was true for them to.
Yes, humans often eat upwards of 15% sawdust in processed foods.
Read the ingredients, where do you think cellulose comes from?
