Alternative to Air-conditions? (lemmus.org)

I am completly opposed to Air-conditions propagandized as a solution to climate change. What is the wright approach to combating this state of temporary relief except from old-fashioned fans? Don't get me wrong. They do the job for me. I am reffering to finding a solution for people more with health issues or large facilities that are in need of something more drastic.

There are some interesting applications where a radiative surface that is shielded from radiation coming back the other way can emit radiation to cool itself by a few degrees below ambient temperatures. There's one paper from a few years ago that describes being able to cool to 5°C below ambient temperature even in direct sunlight with some exotic materials.

Interesting stuff.

Looks like this paper on the topic was only released yesterday. It's more focused on the practical issues of deploying PRC panels, where other papers I've read seem to discuss the tech in a lab setting that may or may not be scalable?
