The original stove

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….

Solar collectors are almost unheard of, even thoe the climate is mild enough for large solar fractions to cover the heating bill. The picture shows an experimental unit made with only local supplies. We believe we can produse these localy at a resonable cost. As in any design or new construction there are compromises and these criterias are set to guide us in the development. It is possible to end up with a very good system that just a few can afford, we could still might have a great buisness, but then the environmental impact would be small. Our dream is to see these around everywhere around here, and therefore it is crusial that we devlop it under criterias guided by our local knowledge.

Price equal to two year payback potential. ( 500 manat for a small system for domestic hotwater)
Made of local available materials.
Manifacture as much as we can of it in sothern Azerbaijan.
A simple design
A robust design
An estetic design (in Azerbaijan people are in general more conserned with appearence than in feks. scandinavia)

This is not a complete list, some would might ask:

“Why isnt high efficency in that list?”

simply because it is not our main priority. Solar collector design can improove efficency by using more expensive materials. But with price beeing such a big deal we can rather increase the effect of a solar collector simply by adding square meeters. So spending a lot of money to increase efficency dosent make sence if the cost for adding 10% area costs much less. Solar collectors have been developed before, so there is nothing new to it, the difficult thing is to make it cheap enough and simple enough so that it can be a “nobrainer” to implement it when you are planing to build your house. It is at that point our company have the desired effect. So our main challenge in this is not to make it work, but to balance our criterias and do our compromises well so we get a product that will be selling enough to make an impact.

“Why not import something from china or Iran?”

This has been concidered, and we might still do so. But at this point there seem to be enough good reasons to do avoid it:

The pricetag is to high (1000 manat and up)
They will not be easy to maintain and tend to be more sofisticated.
It will generate less local jobs.
It will not contribute less to local knowledge and knowhow.
Importing stuff to Azerbaijan is in general not at all effortless.
Most of them dosent look nice.
