Tom and other stovers
I have been working with this aspect for about 20 years now and
do have some miscellaneous experiences. Changes has to come from the inside.
If we want to have some changes at the household-energy sector,
and that is really needed, we have to learn from the very beginning. How
were the three stove fireplace introduced, and later the charcoal-stove? Not
by marketing, not by Tupperware sales, not by NGO's I suppose. I think all
started with the fuel and from the inside by training and failing. People
had the fuel and they found out how to utilize it, and then how to make it
better. They found charcoal was better than 3 stone, and did not worry about
the energy losses by production and the smoke, due to plenty of wood. Now we
can see the results; deforestation, smoke related deceases, high cost fuel
(half of it transport-costs) etc
!5 years ago we had the discussion at a UNHCR run refugee camp
in North of Uganda about mud/clay stoves or metal sheet stoves to replace
the 3 stone fireplace and the charcoal stove. By satellite it was seen the
forest were shrinking. It ended up with the decision of the, that time
strongest NGO, improved clay/mud stove .though the fuel consumption even was
higher than by the 3 stone. Now 15 years later it seems clay/mud stove still
is preferred like in Gulu and now in Peru. We do have the excellent TLUD/ND
and TLUD/FD and some others which provable will reduce the fuel consumption
and are burning free of smoke and soot, but we still have some problem with
the fuel; Pellettizing and briquetting will also demand energy, will pellets
and briquettes be cheaper than firewood and charcoal?
Household energy is this days more a political and environment
task than cultural and practical. A huge amount of people are depending on
charcoal production, transport and sales. More are depending on bio fuel for
cooking. We know production of charcoal reduce the energy-content in wood
with about 70%.
A stove project: should start at the schools with energy and
The first question will be: Is there a need of changes of the existing
situation? The second will be: What is the fuel? Will there be enough fuel?
And fuel to what price? When you have the fuel it is easy to produce the
right stove. For communities in developing countries it is also
socio-economical question. Who will be the loser? Will that be the charcoal
producers and dealers? The winner will at least be the consumers, the
forests and the fuel producer.
Probably also the local tinsmiths will win some..
