This would be a great family activity

Start the project in the morning

Run around all.day doing whatever has to be done

Later that evening Enjoy nice cold drinks chilled to the bone because you have the smarts.

A very handy skill to have

those are cool ;)


another low-energy consumption fridge freezer is to use 8 inches (or more) of styrofoam ... & to build your own.

my first experiment in this regard can hold a piece of dry ice for about 3 days.

Thanks for posting bro. That's a good bit of knowledge right there. Clay pots is one thing I never considered having in my preps.

I think this would have worked a lot better if he put it in a shady area and didn't keep opening the towel all the time.

I'd go with at least 1 inch of sand between them personally.

Evaporative cooling. The only catch is high humidity...no worky so well.

Yep. The thing would be worthless here on the coast where the humidity typically doesn't drop below 80%.

West Texas or the Panhandle- sure.

Gulf coast or deep East TX - not so much. Historically speaking that is.

In truth, this year, humidity readings have been lower than normal at least in the Houston area.... drought and all, less onshore flow from the gulf.

I think it would still work in high humidity areas. Especially if it was in the sunlight.

...but I could be wrong.

The air can only hold so much humidity, and as the humidity goes up the evaporative cooling effect goes down. Swamp coolers work every bit as well as air conditioners in deep west Texas or in the rest of the desert southwest, however in deep east Texas a swamp cooler just makes the air more stifling (when the humidity is high).
