For any reasonable depth (ie. something you'd be willing to dig without specialized machinery), a deeper hole makes for a more stable temperature. The extra mass of soil surrounding your cellar acts to average out temperature changes: shallow burial averages out day-night shifts, while deeper averages out seasonal changes as well. The end result is that a ...

Because water evaporates at any temperature over 32 DegF, a swamp cooler or evaporative cooler is possible in any climate that needs cooling (though perhaps not in a powerful enough fashion depending on the cooling required). In a still body of water, the evaporation rate is proportional (in some form) to the humidity of the air, the air temperature, the dew ...

No, it is not true that necessarily the deeper you get the cooler it gets. For really deep holes it is actually the opposite, the deeper you get the warmer the temperature gets. This is called the Geothermal Gradient. This states that temperature goes up 25C per 1KM of depth. For the first couple of meters the temperature will likely drop or raise ...

It there is a well nearby use it. 1. by dropping sealed and floating containers to water and then using a net to get them back. This works very well with beer cans. 2. Put the food in a bucket and use rope to lower it near the water.

If your ambient temperatures (air/water/earth) don't get down below refrigerator temperatures (2-4 C), and in summer I suspect they don't, then the second law of thermodynamics says you can't do this without an energy source. Since electricity is out, you could consider a propane refrigerator.

You'll need to do several things: Change your habits and foods Work Combine several techniques First, you need to more carefully consider the necessity of refrigeration. Refrigerators are used to keep food in a "safe" temperature zone where bacteria is less active, and this requires temperatures close to freezing. Passive cooling, such as root cellars ...

Although technology has brought us many conveniences most of them require supporting power or other technology. You seem set on refrigeration and you say: "I am willing to go to just about any extent short of buying a fridge and a generator." Perhaps you should consider solar panels (photovoltaic) and an electric refrigerator. Both technologies are ...

The first solution that comes to mind is a "zeer", or pot-in-pot refrigerator. However, this functions best in hot and dry environments as it relies on evaporation to work. Such a device is constructed by nesting one clay pot inside another, with a layer of sand between them (about an inch on the bottom, a few inches on the sides). The sand is then soaked ...

I think this site might have the answer for you. Main points there are: Protect against Hull Damage & Distortion. Do not let the kayak to bend, distort, and getting damaged. Protect from Harsh Weather, Sun & Other Elements. The kayak is usually made out of materials which don't resist the sun infinitely, better to protect them from direct sunlight ...
