Keeping things cool without electricity
Posted by beprepared on June 27th, 2008
In many parts of the world, lack of electricity is an everyday fact of life. In hot climates, it means that food spoils fast, and much of it is lost.
A Nigerian teacher came up with a solultion that uses evaporation to keep items cooler. It means that produce that used to last only a day can be kept for a couple of weeks instead.
The zeer pot is made of two unglazed pots with wet sand in between and a wet cloth over the top. As the water in the sand evaporates, it makes the inside of the pot colder.
A zeer pot will not work as well in humid climates, so, experiment with it to find out if one is right for your situation. Besides keeping produce and other items fresh, it can be used to keep drinks cold when you are away from sources of electricity.
There are complete instructions for making one here .

It’s good to know that your tools will not fail you at a critical time. That is one of the reason that I like dynamo flashlights. Instead of batteries, the light is powered by shaking it, squeezing it or cranking a handle. So upper end models also have radios and cell phone chargers on them.
