minus-squareGangreless@lemmy.worldlinkfedilinkarrow-up2arrow-down1·edit-21 year agoA 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
minus-squaremanillaface@kbin.sociallinkfedilinkarrow-up1·1 year agoWhat’s your source for this? It routinely gets over 100 here and buildings aren’t 80 degrees inside.

minus-squarehairinmybellybutt@lemmy.worldlinkfedilinkarrow-up0arrow-down1·1 year agook, 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.
minus-squareNorgur@kbin.sociallinkfedilinkarrow-up1arrow-down2·1 year agoYeah, 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.
minus-squareDuder167@lemmy.worldlinkfedilinkarrow-up2·1 year agoThe AC is also small compared to a literal building with a sewer underneath and doesn’t require a windy day. Trade offs

pretty sure 50c to 35c is 15 degrees
