[Stoves] Solar cookers

Fri May 16 02:48:18 CDT 2014

Dear Philip,
First, 
thanks for confirming my observations from Southern part of Africa and 
secondly remindming me about the "wonderer", "looking" into the hot Storage basket...............

Due to heavy poaching in Zambia, wild animals are no longer "a problem".........

Paal spend more than 10 years in Africa, in refugee camps and among the "People", not in five stars hotels.
I like to listen and learn from experienced People, sorry.

Solar cookers for heating water, yes...........for Cooking??

We are celebrating Our 200 years Independence from Denmark and Sweden to morrow and I wish you all Happy Aniversery and a Nice weekend.

Dear Philip - 
I could not agree with you more, one thing I find I often repeat to expert expats when they ask why Cookswell does not promote solar cookers is that Biomass ( read photosynthesis)  is nature's own beautiful solar cooker - it has had millions of years of R&D, a wonderful LCA profile and, as with trees, provides so much more in the form of water retention, shade, timber, habitat..etc''..... I would like to see a piece of plastic/aluminium do all that and cook dinner! 

Thats my two cents.

As this is a bioenergy list, I hope we can now leave solar
cookers in the light of Otto’s very sensible comments.  Our own
experience confirms Otto’s observations in every detail.  Solar
cookers don’t work in the Sub-Saharan situation partly because the staple
foods don’t do very well in solar cookers; partly because the cooks
actually enjoy being involved in food preparation, and are unhappy leaving the
food to cook where they can’t taste, stir, smell the process; and partly
because this is Africa, and if some wanderer doesn’t steal your food,
then there is a real prospect that a monkey or some other animal will. 
Tellingly, one failed experimenter wrote “The road to the north is littered
with abandoned solar cookers!” Stick to stoves, brother stovers –
the solar route has been extensively tried and repeatedly failed.

Dear
Dieter,

 I am very much aware of the baskets
for hot storage.

 Low
income households are not entitled to the luxury to plan their cooking, hours
and days ahead.

Meat
or beef (“Relish”) are expensive and hard to find.

As far as I
know, in most part of southern Africa, these households among others, use some
kind of a “porridge” made from corns (Maize).

That
one has to be eaten right after preparation or it will turn into
“cement”, just like potato mash.

In Zambia
(and many other African countries), they used it daily as the staple food
source, called Nzima.

No
access to a fridge or freezers, and occasionally just “fresh” meat.

They also
need to utilize the daylight for work in the fields, also collecting water and
firewood.

After
dark its time for cooking, that’s the fact.

You hardly find people “outdoor” after dark, apart from illegal
charcoal producers and poachers.

The daily
routine is not addressed by the clock, but actually by the sunrise and sunset.

Just what
we were doing in Norway, a hundred years ago……before electricity
and tap water.

Have you ever stayed in a village and listen to the hens start
“calling”, just before sunrise and life begin to become active
again? 

May be in a refugee camp, you can find differences from this pattern, but
that’s not a “normal” situation.

 All
the best

Otto

Dear
Otto and list,

The answer to Paal’s question "What shall you do With a solar cooker, when the sun set and People like to have their warm supper after a long day in the fields?" is very simple: The meal was prepared in the time when the sun was shining, than the pots 
were transferred to hay boxes/hay baskets and all is ready and warm for eating just when people arrive (described e.g. in the book "Fireless Cookery" Seattle 1981)In the case of cooking with firewood instead of that, the meal has to be cooked and people have to wait hungry or they have to collect firewood. 
 In 2011 my wife noted the number of days she cooked with our parabolic cooker (Alsol 1.4) with 1.4 m reflector diameter. On 157 days she cooked all meals of the day, she baked and made conserves and she did not touch her electric stove in the kitchen, 
because solar cooking in the garden gives more pleasure, needs less attention etc. In regions with scarcity of firewood there is regularly more sunshine per year than here in Upper Bavaria.

I think
that traditions (also e.g. that the rice has to taste of smoke etc.) should be
abandoned before the last tree disappeared.

With best wishes

Dieter

Michael N, There are a lot of good ideas out there, but if they are not put into practice or action, what`s the point.....................?
 I was very dissapointed to find out that this was a "scam" and fake in broad daylight. Like Paal used to say:"What shall you do With a solarcooker, when the sun set and People like to have their warm supper after a long day in the fields?" YES, that could have been solved by the Wilson Solar Cooker.
Now, the only Mr. Wilson, I will remember from the US, is the nighbour to Dennis..........that`s all.........:) May be that`s the best way too.Otto
