Mildly Interesting

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.

~~We're talking celsius, I hope for your sake it doesn't routinely get to 100 C where you are. :)~~

Edit: The user actually said 20 F, I got confused by the mix of units. "50c to 35c is 27 degrees" didn't make sense to me, but I figured I'd let it slide. No idea what's going on here. :)

I said “around” 10c. An article said from 8 to 12 Celsius. There’s a paper that said from 46c exterior temperature, the tower can cool the interior to between 34 and 38c. I just rounded things up.

For a solution, we can generate green energy with solar panels and heat pumps.

As I said, the way the tower works is super interesting, but 34c is still very hot to be comfortable.

Yes, that sounds about right - the relative effect of the tower probably depends a lot on various factors like how windy it is, if extreme heat occurs only for a day or if it has been ongoing so that the water under ground is heated as well, etc.

These comments were in response to @Gangreless, who stated that a modern AC "can only cool about 20f below the outside temperature". I didn't catch that it was fahrenheit first, and now that I know I am happily backing off rather than having to think in terms of freedom units.
