  • With some bricks and a little sand, you can keep vegetables cool without refrigeration. Staff from the World Vegetable Center Eastern and Southern Africa Office demonstrate the steps in constructing a simple zero energy cooling chamber.
    In Swahili with English subtitles.

    Instead of the hand, use a brick for measurement between a container or crate. That's what we do in our village for this evaporative refrigeration. Its quite ancient and works well in villages that has power outages quite often.

    • @KalpeshPatel78
      @KalpeshPatel78 4 ปีที่แล้ว +2

      @BrightLight It surely is. If you live in a hot region. Just too much water gets used. There are other methods to keep homes cooler.

    • @KalpeshPatel78
      @KalpeshPatel78 4 ปีที่แล้ว +4

      @BrightLight 1) Tiled roof. 2) Wooden insulation panels. That triangular shape that forms with the roof helps in venting out heat. 3) Depending on where you live and average wind direction you could build it in that fashion. 4) Here in rural India, we also cover external walls with cow dung. It smells when its fresh, but once its dry, it has no smell. Keeps the house cold in summers, warm in winters.

      To use this cooler do you wet the sand or the bricks, or does the wet hessian on top provide enough cooling

    I love to hear Swahili it is such a sweet sounding language.
    Ancient Persians used this technique storing food in big earthenware jars and soaking them at night time. Because they were placed between round buildings the wind would be funneled to blow around them speeding up the evaporation.

    If made into egg the inside will remain cooler. There have been egg shaped containers and storage units made throughout time. The city of London rediscovered a large egg shaped building for storing ice. Unnatural form is a resistor of atmospheric pressure and you will not need to water as frequently if at all.

    It is a good thing that ancient techniques like evaporative cooling are being used again. When I was working in Afghanistan, I saw the use of a giant evaporative cooling fan for a large marriage venue, that was exceptionally effective.

    This is wonderful because I’m in Canada and currently our gas and electric is getting very expensive and we all need to find ways to prepare for anything and not just that it’s a wonderful way that you have used natures abundance to be innovative, and with luming threats of war and other natural disaster’s around the world people may not have this convinces we have turned into a society of convinces and easy lives such as fridges and freezers but if something bad
    happen in the future and going back to simpler ways before modern convinces were so very abused around the world putting nature at its brink of complete loss so I find other ways of using and constructing structures like this invaluable if life becomes ways of old thankyou this was very informative and easy to understand what is needed to build one in Canada we don’t have palm trees or banana leaves but we do have clay and brick and is readily available if ever needed to construct a cooler, blessings & love from 🇨🇦 Canada

    Instead of using burnt bricks and sand, both energy intensive, can this cooling chamber either be built with mud? This would mean digging and using the mud from tbe hole instead ofbuilding using the negetive space as the storage as well as the retaining wall of the hole for stability! Deeper in the earth is cooler. Ofcourse, it would need plastering. Your people are naturally aesthetic and superb builders💚👍

    An hour and a half west of here the climate is quite dry. In the 60s they still used evaporative coolers (electric fan type) in stores or businesses. The mom and pop stores were a cool haven in a hellishly hot place. Hebbronville, Texas is fit only for rattlesnakes, horny toads, scorpions, tarantulas and bats at night. Never go there in the summer! Anyway those evaporative coolers were a Godsend for poor people living there.

    This is a great design and easy to build. In keeping with the all natural theme of the project, could you build a tray slightly bigger than you wanted the plastic to be and grow a kombucha tea scobie (fungus) inside the tray that when dried out and killed be used in place of the plastic? The untreated scobie is not water tight but handles like leather. I've seen videos where coconut oil rubbed across made it more water tight.
    Old plastic sheeting may be easier to find and easier to use than a kombucha starter, though.

    This is a wonderful idea! I wonder if an air vent (1) at one lower end of the chamber having air blown into the chamber; and blowing over a bucket of water would further increase the evaporation by the chamber thus providing even further cooling for cooling water or tea to drink? Capturing sunlight on the shed roof in a hose or pipe would cause an air flow Especially if a sponge drip were incorporated to drip water into the pipe which would expand upon solar heating resulting in an air flow to be blown into the air vent(1) .

    I thought you would need to water the sand in between the brick walls to make this work. I have seen similar devices such as a clay pot with a lid nestled inside a slightly larger pot with sand in between them. In that design the water in the sand evaporates, chilling the contents of the inner pot.

    @donaldduck830 4 หลายเดือนก่อน

    Where I am at, a base layer of sand like that is merely an invitation for ants. Who would then dig up the sand unevenly and then the construction would shift and settle unevenly.
    To make it ant-proof we would need a layer of something caustic, eg (quick)lime.
    Besides the fact that a brick costs almost 2 USD, making this a rather expensive endeavor. I have stored Veggies in a closed container in a covered hole in the ground. Soil temperatures are rather constant, even at shallow depths so it works as a natural fridge and costs a fraction of this luxury building.

  • @portaadonai
    @portaadonai 6 ปีที่แล้ว +8

    When explaining how to do something. It is important to explain why your doing each step. So that the people learning can troubleshoot problems, make modifications, and improve the system later on.
    3:25 You explain to space the containers apart, aw well as the brick wall from the containers. I am sure its because they need good airflow. But you do not say that. This also would explain why your using crates with holes in them, to assist in more airflow.
    When someone understands this, and why evaporative coolers need good airflow combined with moisture it makes a big difference in their ability to contribute instead of mindlessly following instructions.

    Probably won't be useful in your climate, but evaporation refrigeration is awesome - you touched base with that and digging a hole. But you can also incorporate wind, natural cooling in the ground, and solar heating to get things to 4-5°c.
    Of course though, if you don't have wind, you can simply use a solar powered fan. And if it's not hot where you are, fresnel lenses used carefully can help (just don't start a fire)
