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.
