The great thing about the absorption system used in A kerosene fridge is any flame or heat source will do. There is no moving parts to worry about.
I'm thinking of custom building one ...

A 12 volt system would be costly electricity wise unless you incorporate high R value insulation.

The Stirling method involves A motor.
Needs something to drive it or A heat source.
Although A Stirling motor is really versatile.
The different configurations make it so.

From my understandings I would use it more for generating electricity or mechanical energy.

This is essentially the same as using a well, or a well house, to keep things cools.
Here in north east Arkansas, we suffer from the same problem as those in Oklahoma. The water table prevents root cellars, unless you build it above ground, then cover it with plenty of dirt. Extra insulation wouldn't hurt either.

Here is a refrigerator which operates without electricity:

The refrigerator operates on the same basic principle as evaporative “swamp coolers” that help keep houses cool in hot, dry climates. The design consists of two cylinders, one inside the other, with a gap between the inner cylinder and outer cylinder. The inner cylinder is made of solid metal. The space between the inner and outer cylinders is filled with a layer of material that can be soaked with water, such as sand, wool, or dirt. The outer cylinder is made of a solid material such as wood or plastic, with holes drilled in the sides to let the sun’s energy reach the wet layer.

Awesome! Thanks for bringing that up. I remembered reading about it AFTER you had posted this article.

That makes me think of a new thread Survival: What information we have forgotten

Doc,
may I use your alternator and fan gizmo, in my pamphlet? I'm putting together a complete, 'What I need to live underground' kind of thing. It's got everything from using algae to scrub the CO2 from the air, to hydroponics and herbal medicines.
Thanks,
Jim.

Help yourself Kadipa

I can't find the exact one, "article" a young women did it in either high school or college and this is as close to it as i can get.
www.scientificamerican.com...

Not sure if I would trust it with much more than basics, "I'm not gonna put a half of beef in it" but I would like to see how affective one could be, and freezing, thats another story....
