I had a very encouraging trip to a nearby village recently, and it gave me some additional information on design needs. But first and foremost it was very encouraging to be so well received. It is always encouraging to build friendship as making friends is important and people even make friends and partners online with the help of site like chatsex online. It looks like this can be one of the places we will start to spread our ideas.
This is a photo of the original kind of stove found in most villages around here. They have to clean the pipes monthly because of the creosote build up in the 10 cm flue pipe ( sign of bad combustion) And with only 1mm sheet metal in the construction, combustion temperatures end up way below the point where most gases are consumed. The expected life of this stove is one or two years! So there are plenty of room for improvement to this design.To keep this going they need two truck loads with wood to stay warm in the winter. (That is aproxemently 80 meters of 30cm wood or 25 square meters). The good thing in villages is that because of the high thermal mass in the buildings the house stays comfortable during the night as the walls gives of the heat they have charged. This households man is a little bit more clever than most because he let his pipe run through the room upstairs, and the boards between the rooms had purposefully half centimeter glitches between them so that the heat could come through. It actually worked ok. Almost like in floor heating upstairs. But he is very exited to try out a different stove that will save wood, and save him the work of cleaning the flue pipes every month.He also expressed the importance of the stove being good for cooking, so this is something we have to emphasize in our design, as it can be a deal breaker. If we succeed in his house he wants to introduce this stove to all the houses of his village. He wants to partner with Tamiz and learn how to make them. In this way he will make him self a small income, at the same time people in the village will save money and increase their comfort + the big end product for us all is that we are reducing emission and cutting of a valuable forrest. This is how change can come, by knowledge and training village after village. Our hope is that once the rock is thrown and proved its impact, the idea will start spreading like rings in water….
