[Stoves] Thai Bucket Stove

[Ronal W. Larson]

Nikhil et al:  (Adding Paul)

	1.  Looks like a good report.  I wish I had time to do more than skim.  Winrock has a long history with stoves.  We are very fortunate that they remain involved with GACC and EPA.

	2.  The most interesting paragraph for me was this at the beginning (p25) of Annex 1, noting the factor of 9 (nine!) in the efficient use of a diminishing resource.   (Sorry that I had to use a screen shot, as the publishers prohibited a simple copy)




	3.  The charcoal stoves are reported to have an efficiency of about 1/3.  But (including the energy density differences of 18 and 30 MJ/kg), the real efficiency expressed by this factor of 9 is about 5 or 6 %!  

	4.   5 or 6 % is unacceptable everywhere but especially in Rwanda.  See what pops up (Gorilla deaths in first place) when you google for “charcoal legality Rwanda”.  The outlawing of charcoal occurred in 2004 - before this report.

	5.  Rwanda (and other countries) could help itself by saying that sale of charcoal needed proof (when and where) that there had been productive use of the pyrolysis gases.  Costs should also go down - not up.  Employment should go up as wood is prepared.

I think he started the reported ESMAP activity in Kigali but stopped in 1994 after the genocide until we went together in 2004. I became a target of Kagame's internal security and intelligence apparatus, but Robert continued and produced some other reports, including some mentioned in this Winrock report that also has some history of stove projects at the end.

In his book “The Kenyan Ceramic Jiko – A manual for stove makers” (IT Publications, 1991) he says the production system present was developed between 1986-1988.   The book is contained in the AT Microfiche Library from Volunteers in Asia. IT Publications, ATI and CARE are credited for the book.

Hugh told me the reason he was contracted to work on the stove was the difficulty in getting reliable results from the kilns: losses of something like 40% were normal in the firing.

He introduced dome-topped kilns and spread the production technology to the Sudan, Uganda, Tanzania, Togo, Malawi and Rwanda. In short he “professionalized” the product, bringing firing losses down to 3%. Later he led the same type of exercise with the Bielenberg sunflower oil press which inspired me greatly.
