minus-squareGangreless@lemmy.worldlinkfedilinkarrow-up0·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-squareNorgur@kbin.sociallinkfedilinkarrow-up0arrow-down1·1 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-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.
