Back 10 years ago during the Scouts’ camps and Jamborees, we used the same concept to cool our food. Our concept was with papier mache instead of fabric or charcoal. It was very effective, as well as a way of recycling pieces of paper

The African sand pot would seam to be a better idea, the materials can be localy produced and and are cheaper.

And by the way, it is also called an earthen pot.

I am not sure why there needs to be any buzz around this type of cooler. In India, we have used the same concept for thousands of years. It is really cheap and works effectively. It is called a ‘Matka’. Almost any Indian will tell you that it works more effectively than the device you described and it costs about a dollar or less. The size of ‘Matka’ for that price (<$1) holds more than a gallon of liquid.

While it is cool it aint exactly new and innovative like the article is proclaiming,indeed Dominic Wanjihia would even have a hard time laying claim to this as an invention as this kind of thing has been around for a very long time and is nothing more than a slight variation of `The Coolgardie Safe´ invented by Arthur Patrick McCormick in australia way back in the 1800’s

still quite a thing nonetheless

Interesting fact, but hardly amazing, since camels live in the desert, they have probably adapted so their milk glands produce more temperature stable milk.

Anyway, some guys at Stanford are also developing a low-cost refrigeration system, but on a completely different basis. Se the TED talk:
http://www.ted.com/index.php/speakers/adam_grosser.html

The thing about technologies presented on this blog, there all great and
all, but there’s lots of room for improving them in terms of efficiency,
cost, ease of use, etc. These inovative people should work more closely
with local universities.

Another amazing fact – according to the Dairy Farmer http://www.havemilk.com/article.asp?id=1485 In the hot desert, camel milk lasts longer than other types of milk. It can last for seven days at 86 degrees Fahrenheit (30 degrees Celsius), and will last for three months when properly refrigerated.

This design could most likely be optimized, so that it could cool down the
milk or whatever even further. It would probably be a good idea to
involve some engineers that specialize in cooling technology in further developement or at least ask them for some advice.

Hi Paula, and hi Tom
Evap cooler
This design is specific for large scale and porervty eradication in remote rural areas. Tom, as a cycle user, you are probably adopting the same fine line technology but on a micro level – hence bacteria proliforation. If there is a need on a commercial scale, i’m more than confident i can come up with a solution.
On the otherhand -
The moss concept increases the evaporation surface area – hence increases cooling.
Moss is organic is clean, can begotten anywhere and it works.
Note also, low concentration chlorine will not destroy Moss.

UV
Yes, UV desroys most harmful bacteria in “clear mater”. UV cannot penetrate brown river water. It is applicable in settled waters – dams, lakes ect.

Be good, dom
