Dear All, I am Anh from Vietnam, I am new in here, been reading for a while and this is my first reply.
We are a new start up, private social business in Vietnam making improved cook stoves and decentralization is what we are trying to do. The plan is to make parts in Hanoi, capital of Vietnam, and ship out to other provinces and set up assemblers shop there at local households to put the part together and distribute in their area. If this work, with consumption of ~300 stoves/month we can shift 1 job from city to rural area where the job definitely have higher value. Also for the business, we can save tons of costs such as workshop, warehouse, transportation,... and have replacement parts stored much closer to consumers. Til now, we are close to get the first assembler up, there's still a lot of issues but hope it will work out fine. As for fuels, we had plan for a facility making biomass briquettes/pellets too but had to cancel it due to the difficulties in securing raw material supply. As biomass come from all around and many come in by season (rice harvest only happen twice a year to have straw), its very hard and costly to collect and store the biomass for production all year. One of our project is to equip multiple small scale briquetting machines to local people, teach them how to produce and purchase all of their output. Decentralize has many issues in quality, training, production safety,... that much harder to control but sometimes it is the only way that can work the economic. So I guess the absolute answer for Centralization or Decentralization must depend on each case or we can just use mixed mode.

"centralisation" or for that matter "decentralisation" Message-ID: <[email protected]> Content-Type: text/plain; charset=iso-8859-1 Paul, Hoping this gets through the filters of this group, you nicely describe the very philosophical differences I have with the centralize and mass produce movement at least for these technologies; We have had major success self sustaining success at that but by the very nature of it the centralized worlds access to it, such access tends to consume it to little beneficial end for the local producer/trainer. The whole idea of development surely cannot be to simply replicate our western industrialized model of development on the global community. It's a model that you in your own profession well know has serious distortions to the global economy given for example, our resource consumption patterns as against our proportion of the world's population, and the mere carbon footprint we make in trying to extoll the virtues of centralized mass production and distribution ---where such technologies as these can be managed at the local level. It's certainly agreed that pure localized one-off initiatives are labor intensive to say the least and so much is lost in the process, as the learning is not generally transferred by the trainees-trained as trainers, to emerging groups in their own area. To me, its is not about "centralization" but about localization of initiative and responsibility and localization of reward--globally. Its about functioning as a mechanic of the process, to encourage this to happen in such a way as to assure local responsibility and initiative. The process is monetised to assure self sustained participation . Everyone works at risk and reward and responsibility locally but the participants also learn to share their findings globally And for 2014 as initially suggested by many colleagues, we are bent on assembling an anthology on the subject by those who have been directly involved in it. Knowing we all share the same end goals, all the best to you and the other many good like minds for the new year.

The internet model is the proof of the pudding. The internet could never have been built by the centralized model! A key aspect of the decentralized model is that it is the most effective way to leverage the human and financial capital resources at the edges. These are far vaster in aggregate than anything the centralized model can arrange. The simple fact is that the problems being addressed require a level of resources that ONLY the decentralized internet model can deliver. The under resourced central model can only fail, as any badly under capitalized business knows. Best Wishes for a Distributed & Decentralized 2014. Jock Jock Gill P. O.

I suggest we are apt to see a mixed mode for stoves: centralized manufacture of key parts and decentralized assembly. This is the World Stove model (based on least cost principles - import duties, quality control, attractive design, added services, etc). I worked twice for a small local PV company in Zimbabwe, and this was their key - provided much better service for customers than any of their competitors, for small parts - not the panels. 2.
