Our last "week" of fieldwork was spent in Berlin - a coffee growing area that's pleasantly cool as its about 1000m above sea level. The contrast with other areas in the amount we got done was impressive - we only spent two days there, but we had two guys from the city council assigned to help us and show us around, along with a car and driver, which meant that we were able to do 24 interviews, despite the fact that they were distributed in ones and twos all over the province, and we visited almost ten houses where the stoves were unoccupied as they were either unfinished or only recently completed.Tuesday morning was an early start -
leaving with Douglas at 5am to get to the City Council when it opened at 7, as we expected to have to wait for at least two hours before they got anything done. Amazingly when we got back from a tasty breakfast Toño was already waiting for us, had found out that we weren't going to get a car that morning and was waiting for a helper, Reynaldo, to turn up and help show us around. These two ended up showing us around tirelessly for the next 48 hours, first of all in houses REDES had built ar
ound the city with improved stoves, and then after lunch and on Wednesday in remote villages all over Berlin municipality. They were great fun and made the trip into the success it was - not least with the endless banter about how Reynaldo wanted to find an English girl to marry, which soon developed into the plans for his wedding with Steph...I think she was secretly gutted when he didn't come back after lunch for their arranged meeting at the church to finalise things!
Berlín is a beautiful municipality, spread across the slopes of a volcanoe, and we had some great opportunities to see the scenery from the back of the pick-up while driving hither and thither to visit communities. The interviews produced some interesting results - for example REDES gave the families no training whatsoever in the use or maintanence of the cookers, something that we were shocked by as we expected them to be more clued-up than that, its certainly one of the things that we're going to recommend they change as a result of this investigation. The design in question is the "3 hornillas" - it has a large circular hole at the front for cooking with a comal or a large pot for maize, frijoles etc. and two smaller holes at the back with sheet metal covers for cooking with smaller pots.It turns out that this design is wildly inefficient - it does use less
wood than an open fire with a tripod pot-stand, but only by 10%. In contrast the Rocket had an average saving of 60%, and the "plancha" design of stove an impressive 50% reduction. The main problem with the "3 hornillas" seems to be what we expected - it has a very high thermal mass as it's large and made primarily from bricks and mud (although it does also contain ash) and one of people's main complaints was that it takes a long time to heat up, which uses lots of firewood.
On Thursday we had managed to organise a trip to Sonsonate to visit the Stove Team International factory there thats making the brand of Rocket stove that we've been testing, the eCocina. It was an excellent trip, very interesting to see the processes that the stoves go through, and also some of the other designs, including on we'd sighted on YouTube and wanted more information about. It's based around a rocket-elbow combustion chamber, but T-shaped and made from reinforced concrete. The cooking surface is a large plate that can easily be used for tortillas or pupusas, and there are two removable metal covers which reveal "burners" for cooking with pots. All in all it seems to answer the problems we have with the Rocket - namely that its too small for large families and can only accomodate one pot at a time, and at a price of $125 it should be affordable for future REDES projects - the only drawback is that its still made in a factory so the opportunities for involving the beneficiaries in the contruction process are limited to building a base so that it sits at a comfortable working height.We had planned to return to Suchitoto to finish our adobe Rocket stove with a layer or reinforced concrete, but unfortunately it doesn't look like I'll get a chance to do that now - first I went and got ill, and then this week has been spent writing the presentation on our investigation which we're giving to a combination of engineers, site managers and directors of REDES on Friday - wish us luck!
Oh and to finish - a photo of a traffic-directing clown. Why? I don't know -
you tell me!
