Dear Ronal, Nolbert and all,
I dont think there can be fixed priority order of the selling point, must based on local demand. It happen to us in the small area we covered so far in Vietnam that the reason to buy the stoves varies from area to area. An additional selling point that may not make a lot of sense but it did work especially in sub urban area is that the stove is clean, tidy can be used anywhere (outside the traditional kitchen for three stone stove) and looks modern. Batch aspect of TLUD: you still can always add more fuel, so it doesnt matter much, just need to time the burning rate right to add at the right time. From what I know, batch time varies based on fuel so it varies from area to area and end users will learn it very fast from their own fuel. By continuous running: what time range, cooking demand are we talking about here? We all know TLUD is much better for health but sadly most users doesnt know or care much about it as they've been cooking the old way for generation. This would need a lot of supports to raise the issue to their attention. Anh From: Stoves [mailto:stoves-boun...@lists.bioenergylists.org] On Behalf Of Ronal W.

A few questions: a. Are they in priority order? Might the order change for different types of customers? (say by income?) b. Any way of saying how much of each selling point is needed to move away from a traditional stove? c. Does the batch aspect of TLUDs turn some/many of your customers off? d. Guessing the TLUDs won't handle all cooking, can you say for what tasks they are using them (water boiling, etc)? e. At the recent Ethos meeting, Michael Johnson of Berkeley Air Monitoring talked about a new approach for encouraging, for health reasons looking at daily maximum exposures, displacement of the dirtiest stoves with the cleanest. Any information you can pass on to GACC along those lines? f. Do you need and have subsidies to get greater adoption rates? g. Anything big I've missed? To others - see https://www.facebook.com/awamubiomass. Nolbert is working with Paul Anderson.

Time and fuel saving (cook faster, with much less biomass) 2. Use a wide variety of biomass (this has issues with chopping wood especially for rural Uganda) 3. Makes Charcoal that can be re-used in another charcoal stove or as biochar 4. Clean (less smoke aka toxins - but they dont really understand emissions) These are clear for potential users when we do a demo in villages. Nolbert. 2014-01-29, Ronal W. Larson <rongretlar...@comcast.net>: Antony - with eleven ccs 1. First note nice help offered by Alan Cave in several messages yesterday. They did not include your original request below. I agree with his remark that the continuous Belonio stoves that you found at Paul Anderson's sites are down draft (BLDD) - and that may be the best way to go. At the recent ETHOS conference I do not recall this topic coming up. (I wrote 3-pager on that conference - available at the stoves site.) The reason is the strong emphasis on stoves that cost $10-$20 - and I doubt we can ever see continuous feed stoves in that price range. I talked to Dr. Belonio a good bit over the last weekend, but this topic did not come up. I include Alexis as a cc, as he is probably the best expert on this topic we have. 2. I include the stoves list, because there is apt to be more expertise there on your stove question than on the Biochar-production list. Tom Miles added because he manages both lists and will have valuable thoughts. 3. I Include Jerry Whitfield, Jock Gill, Alex English, and Marc Pare as they have all written on continuous feed char-makers; but none I think for stoves. These are probably all horizontal feed (augers, moving grates, etc.). See http://www.whitfieldbiochar.com (that is apparently in a "hold" mode). Apologies to anyone I inadvertently left out who has been thinking of continuous-feed stoves. 4. I include Dean Still and Ranyee Chiang as the best way to get this topic into GACC discussions. 5. Can you explain more on why you are interested in this topic for stoves? Do you have an upper price limit or particular stove application in mind? Would several low cost batch TLUDs operating sequentially in parallel meet your needs? I consider the non-continuous aspect of TLUDs as their biggest drawback - so think we should all take this topic very seriously. I thank you for bringing it up. In my mind, the other advantages of TLUDs (primarily time savings and money-making) outweigh this disadvantage. But it would be very nice to remove this disadvantage whenever an application allows the extra expense that seems sure to accompany continuous operation.

Do you know if anyone developed a biochar-generating stove that can run continuously? Something that: - Produces water-quenched biochar - Runs continuously on pellets/chips - Unlikely to set fire to feed hopper - Flame can be used for cooking What I'm thinking of is something like: http://imgur.com/a/BGADk Google has showed me: The BEK biochar generator http://bekbiochar.pbworks.com/w/page/6465132/FrontPage - Not for cooking Wallace's biochar generator http://terrapreta.bioenergylists.org/wallaceACpatent - Not woodgas-running Belonio's continuous rice husk generator http://www.drtlud.com/2012/04/04/rice-husk-gasifier-new-papers/ - No quenchable biochar?
