Zeer pot clay fridge - preserving food in Sudan

[Unguidedone]

what is its operating temperature at?

[popapape]

This is amazing. I hope someone can explain it a little better.

@popapape

Not much to explain.

When water evaporates it takes a lot of heat away with it. The same reason we sweat and cool off. Tthe insulating sand layer keeps heat out, and the water evaporating keeps the center from heating up.

This design uses 2 clay pots which are POROUS, so they allow water to leach out and heat to leach in and evaporate the water in the sand. Which takes the heat out of the top and internally cools slightly. (sand works better than dirt)

what i want to know is when she puts the lid on Does the Light go out?

[a10fjet]

this would work even better with organic solvents instead of water, like alcohol.

[supressorgrid]

@a10fjet Or gasoline.

@a10fjet

Thereby completely negating any positive environmental effect, and sucking the "green" right out of the whole idea.

Hey I have an idea, this would work better if you used a small condenser a motor, and some freon and shoved it all inside a steel shell. We can call it an "ice box" we will be so rich if only we existed 100 years ago......

And simpleton people wonder how they did it in ancient times! lol....  simple, they use full power of their brains to invent stuff naturally and effective.

[bunnybaybe]

Beyonets, i'd like to see you design something as useful with what they have. It's easy to criticize when you're not living it.

[hottluv32]

Wow! Simple really is better. Eco friendly and easy to use. Great invention!

Or just bury it in the ground in one clay pot!!!

Yhumbs up if you came here from HouseholdHacker

[steve2497]

Just wondering, how often do u have to water the soil in between? Once a day maybe?

[practicalaction]

Thanks for your comments guys, we really appreciate it. The zeer pot has been a huge success for people living in hot countries like Sudan. Being able to keep food fresh for 20 days rather than two has made such a difference to them.

@practicalaction Hi, does this work in temperate climates? I'm busy with a project to settle in South America with a group of people, create our own village based on the Cal-Earth super adobe buildings. We wish to grow our own food and not be much dependent on others or on electricity. This would be a good addition.

i like this video:)

Practicality at its best.

[EarthIQ]

Very nice for the transition to a more sustainable lifestyle, especially in dry, arid climates.

@bayonetsluts No need for such rude language. Different cultures do what works for them, that's all. I respect that.

[mryellow123]

@bayonetsluts heh just about everywhere in Australia used evaporative coolers up until 30-40 years ago. In outback areas many still carry evaporative waterskins on the bull-bar of their truck. You can buy them at most camping shops. Strange how science that has worked for thousands of years just keeps on working. Evaporation even cools trendy skinhead pretend nazi's too.

[itisphoto]

This only works if you live in a dry area. If the air is already humid; not a lot of evaporation or cooling will occur.

[dafranx]

What an excellent and simple invention! Is it better than a cooler? Now people can store produce in this simple fridge.

[asubjectiveopinion]

What a brilliant and simple invention.

Thanks for posting.

[WorldStove]

lovely idea! will try to make one this weekend
