Roasted wood is incompletely distilled wood: due to a lower temperature, only the most volatile fractions of its components are extracted.
As these are the most difficult to burn properly and are therefore responsible for the emission of annoying fumes, we can clearly see the advantage of this product.
In addition, roasted wood retains a large part of its initial combustible components, which means that it contains more energy per unit of volume than charcoal (which contains only the carbon fraction, as its name l 'indicated).
If the charcoal is more caloric per unit of weight, it is at the cost of an energy waste during the manufacture and the use: it takes more energy to expel combustible products which will obviously miss then during the combustion.

Another point, the roasted wood retains the dryness acquired during manufacturing because the wood thus treated becomes very little sensitive to moisture uptake (unlike dehydrated wood in an oven which then gradually equilibrates with the humidity of the air), which further increases its heating capacity.

The fact that this product is positive in environmental terms should not make us forget that it is part of a totally negative overall scheme, since it is mainly used in our countries for cooking meat products, the consumption of which is one of the factors responsible for the deforestation.

Furthermore, it should be noted that charcoal is a fuel widely used in all impoverished countries for preparing meals. The consequence is a huge waste and another cause of deforestation. In the current state of things, a switch to roasted wood is unthinkable because roasting requires equipment beyond the reach of these populations.
There is, moreover, a vicious circle because charcoal is both cause and consequence of deforestation in these countries: as woodland recedes, only charcoal can be easily transported over long distances, due to its high energy density.

hence the usefulness of training populations in the construction and use of solar ovens!


I really believe in it!

in fact "the happy medium" and if for your humanitarian project, you offered to accompany the water drawers by carpenters to train the populations in solar cooking (forest protection requires)

@ Hasardine:
It is perhaps a track among others… For my part I would be less affirmative.
Even if the construction of these ovens is simple, it should not be forgotten that in these countries, everything is complicated ... In addition, is its use adapted to the different local contexts?

Other tracks:
Improved stoves are a big step forward by halving the amount of wood consumed.
The Norwegian pot would also be a promising avenue and would have, in addition to its economy, the advantage of relieving the work of women: they would no longer need to monitor the cooking. Freed from this drudgery, they could devote themselves to other occupations more profitable for the whole community. We hardly measure the importance of the role of women in the evolution of these societies ...

Even simpler, a reorientation towards a food based on raw products would limit the harvest in the forest while improving the content of the ration in enzymes, proteins and vitamins (largely or totally destroyed by cooking). This last point is very important in frequent situations of food deficiency.

cooking is for most women not only a pleasure, but also a pride in serving what we have done with our hands, let's not try to change deep cultural habits, but here is a video that proves that can walk!

I fear that I have not explained myself well: I do not propose to take away from women the pleasure of cooking, but a few avenues for relieve this work and improve family nutrition (this last point is still one of the goals of the kitchen!).

That said, your video is very interesting, even if it only proves that the manufacture of a solar oven is simple, provided you have a minimum of tools and materials.

Ahmed, don't take it badly, but if there is one area in which most women can't stand taking lessons (and I'm one of them!) It's their cooking, it's an area in which most of the husbands should not interfere under pain of passing themselves to the pan!

PS: And yet it was my husband who taught me everything in cooking! and who, sweetly and adorably, from time to time adds books to my library when he sees that I am fishing in this or that area (recently, yogurts)

Don't worry, Hasardine, I don't take it bad at all! I still think that if your comments came from a man, they would pass for macho…

I think we must avoid any confusion and not project the idea that we have in Europe of a "housewife" on the situation of African women. Too often their big concern is not what recipes to cook but if they will find something by the next meal.

You say:
"… Let's not try to change deep cultural habits…"

However, the culture is not (fortunately!) Unchanging, and there are a lot of changes in food traditions (not necessarily positive) under the influence of the colonizers (shift from the consumption of millet to wheat, e.g. ), pressure from the environment or demography (which means that you have to give up picking for cultivation, for example).

Changes that increase the chances of survival are obviously to be encouraged; don't you yourself suggest using the solar oven?
