Ron will probably have more complete notes but they may be delayed since he will be travelling South tomorrow to visit Burn Lab and then to join an Open House at Aprovecho Research Center where he will be testing some new design concepts. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>8:30-9:20 Today opened with another fascinating series of US DOE funded research projects:<o:p></o:p></p><p class=MsoNormal>Jessica Tyner, Colorado State University, on modelling and testing TLUDS. Very advanced models validated by extensive testing. The first extensive gas analyses that I have seen with changes in gas compositions with different wood species. Cool simulations and video images of gas patterns in different configurations. Conclusions about how refueling TLUD affects performance. This stimulated a lot of discussion about fuels, fuel geometry, and operating conditions. <o:p></o:p></p><p class=MsoNormal>Michael Johnson, Berkeley Air, described various special purpose sensor used as part of a ”Platform for Integrated Cookstove Assessment. <o:p></o:p></p><p class=MsoNormal>Dean Still, Aprovecho, presented a critical summary of a year’s worth of testing and development that culminated in a publication on stoves. Dean showed TLUD and rocket stoves under development with chimneys (to comply with WHO standards) and catalysts. <o:p></o:p></p><p class=MsoNormal>These presentations generated a lot of discussion, not only about the content but also about methods of delivering the content to the stoves community. We will link to the information as it is put online. The presentations will be on the ETHOS site and the USDOE papers will be available online through Open Access sites. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There were lots of questions about fuels. At the formation of the Global Alliance for Clean Cookstoves some of us participated in a working group on fuels in which we set out a series of needs and priorities for research and development. I have been told that GACC has done quite a lot of work on fuels. We’ll see what we can find out about that work. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>10:11-20. Sessions on Design/Performance, Emissions Equipment, and User Research/Adoption. <o:p></o:p></p><p class=MsoNormal>In the User Research/Adoption category Paul Means, Burn Lab, presented results of surveys and visits in a presentation titled “Beyond the WBT: User Research and Cookstove Development.” This study covered many aspects of user adoption that we are familiar with, such preferred stove height, weight, diameter, and performance in the lab vs in the field. Paul described several problems with surveys that they solved through simple demonstrated rather than questions that led to useless information. <o:p></o:p></p><p class=MsoNormal>Elisa Derby described a “Consumer Research Toolkit for Improved Cooking Technology Options.” This was a clever adaptation of a survey tool developed by the US Census that conveniently analyzes survey data for you. She showed examples of how the tool works with some simple analyses. It was suggested that we have surveyed stove users to death and that we should just get the product out there and see if it sells, IF it doesn’t then do something else. <o:p></o:p></p><p class=MsoNormal>Danny Wilson, Berkeley Lab, demonstrated a tool for analyzing SUMS data. Custom programming has been developed as part of a PhD thesis to substantially reduce data crunching.<o:p></o:p></p><p class=MsoNormal>Nordica MacCarthy demonstrated “Engineered Systems Modelling and Decision Based Tools and Their Applications for Village energy”. Using data from Nate Johnson’s work in Mali, she showed how household cooking energy is interrelated with other energy uses and needs such as lighting and water heating, and how solar or other devices could be used in combination with stoves to meet energy needs while increasing capacity to increase household income, improve health, and reduce climate impacts of alternative practices. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Design Performance, Modelling presentations included:<o:p></o:p></p><p class=MsoNormal>Sam Bentson , Stovetec,A planning Tool for Stove Developers With Indoor/Outdoor Air Modelling<o:p></o:p></p><p class=MsoNormal>Dale Andeatta, Pot skirts as a Means of Improving Efficiency of Plancha Stoves <o:p></o:p></p><p class=MsoNormal>Pundle, Predicting Natural Draft Rocket Stove Performance Using Computational Fluid Dynamics.<o:p></o:p></p><p class=MsoNormal>Allawatt, A Simple Heat Transfer Model and Applications to Stove Design<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Emissions Equipment<o:p></o:p></p><p class=MsoNormal>Seidel Hatfield New Equipment Development at Aprovecho<o:p></o:p></p><p class=MsoNormal>Caubel, Recalibration of Dustrak for Biomass Cookstove Emissions<o:p></o:p></p><p class=MsoNormal>Ebeola-Martial, Quartz Filters as a reliable and Economical Alternative to Teflon Filters for Measuring Gravimetric PM2.5<o:p></o:p></p><p class=MsoNormal>Thompson, Emissions Measurement Equipment: Behind the Lies<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>11:30-12:30 pm<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>New Applications<o:p></o:p></p><p class=MsoNormal>Peter Schwartz, Cal Poly, Solar Electric Cooking: Coming Soon? - student projects at Cal Poly<o:p></o:p></p><p class=MsoNormal>Larry Winiarski, Rocket cyclone incinerator<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Combustion Products<o:p></o:p></p><p class=MsoNormal>Michael Johnson, Berkeley Air, In-field black carbon emissions from cookstoves in Asia and Africa. Michael showed results of black carbon emission from many stoves and locations compared with standards. This was BC only and did not include organic carbon (White) emissions, inorganic components or gases such as CO. <o:p></o:p></p><p class=MsoNormal>Erin Rasmussen, Natural Charcoals, So Much More Than A Cooking Fuel. Erin described biochar and how it is used for water filtration and as a soil amendment. She showed how it can be made in developing countries with a Jolly Roger or other carbonizer with examples from Josh Kearns work in Asia. <o:p></o:p></p><p class=MsoNormal>Francesco Tortorici stepped in to fill a no-show and described a project in Port Townsend, Washington, in which biochar is being used to filter zinc from boatyard effluent to demsontrate how biochar sould be used as a filter. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Expanding Our Impact<o:p></o:p></p><p class=MsoNormal>Ross, Empowered Entrepreneur Master Trainer Program<o:p></o:p></p><p class=MsoNormal>Crystel Cheong, Malawi, Building 2 million stoves by 2020<o:p></o:p></p><p class=MsoNormal>Lipp, Fire That Talks: Exploring the Connection Between Ethnolinguistic Identify and Clean Cookstoves<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>2:00-3:30 Discussion - What We Want from ETHOS going forward<o:p></o:p></p><p class=MsoNormal>This was a lively discussion about the conference, what we liked about it, what we though was lacking, and how we want to continue as a “conversation”. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We had 140 plus attendees in our 16<sup>th</sup> year. Many participants were enthusiastic newcomers there from all parts (Zimbabwe, Malawi, South Africa, etc.) for the first time. We lacked some of the foreign participants and a few manufacturers/project developers. Some attendance was affected by the recent attendance in Ghana and in the ISO working groups. Seve3ral people concluded that it was the best stoves conference that they attend. There were many suggestions. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>3:30 – Lighting of the stoves<o:p></o:p></p><p class=MsoNormal>Lots of great examples this year of rockets and TLUDs in many different configurations from tincanium to sleek stainless steel models. Paul Anderson demonstrated the Mimi-motto along with other designs. Seachar had a new estufa finca design that sported a water cooled TEG by a third party.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ryan and Clark(?) of Mountain Air Technologies (Aprovecho) tested a compete air quality sampling that they developed with PM, CO, etc. Cool stuff! <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Leon Johnson brought out a “Kon Tiki” bio char maker that will reduce 3 m3 of biomass to 1 m3 of charcoal in 2-4 hours. His company recently built it and is using it to make biochar for their organic soil blends. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We’ll put pictures of these devices up on the stoves website. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Kind regards,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Tom<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>T R Miles Technical Consultants Inc<o:p></o:p></p><p class=MsoNormal><a href="mailto:tmiles@trmiles.com">tmiles@trmiles.com</a><o:p></o:p></p><p class=MsoNormal><a href="http://www.trmiles.com">www.trmiles.com</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
