Free Cooling of food or rooms in hot climates

The main reason for this project at this time is to gage interest.

I may be wrong and maybe there is no interest in which case I will go no further.

If I see enough interest I feel this project is definitely something we can make and if it makes life better for some people it's worth doing.

Let me know.

This project was started to entry the 2020 Hackaday prize contest.

Strangely enough they ask for heating but I always thought cooling is harder and sometimes can be more useful.

Even living in a rather cold place, summers are hot and food perishes quickly unless stored in a fridge.

While the cooling box I propose may not be as good as a real fridge it should help keep food safe longer or make the home interior more bearable.
