The Biomass Energy Foundation (BEF) announces: BEF Stove & CHAB Camps in 2011 (CHAB = Combined Heat And Biochar).

1. The five-day BEF Camps feature hands-on experience plus theory & instruction on gasifiers of numerous types, but focusing on pyrolytic top-lit updraft (TLUD) technology for cookstoves (and larger devices for thermal energy and biochar at the CHAB Camps).

2. At least eight (8) BEF Camps are being planned, including one on each inhabited continent, and one each in Spanish and Portuguese. The schedule (subject to alteration) is:

USA---Set dates: February 7 - 11 at Chip Energy, Goodfield, Illinois, Indoors - See separate details below. Contents include the latest TLUD stoves; Chip Energy Biomass furnaces; Strategy; CHAB production.

Each of the following is during one week between March and September (not listed in order): (ALL include TLUD stoves)
  • India (hosts & locations being discussed) - institutional stoves, cottage industry thermal energy, fuel issues
  • Australia, with Dr. Paul Taylor (biochar expert) near the Gold Coast - Biochar prod & characterization
  • Uganda at CREEC at Makerere Univ in Kampala: cookstoves, fuel issues, PEMS emissions testing
  • Mozambique with ECPF or WWF in Pemba, TLUDs for reduction of deforestation - In Portuguese
  • USA at NESFI in Belchertown, Massachusetts: both CHAB and Stoves, include policy and research
  • Europe (hosts and locations being discussed): CHAB, residential heating, European issues.
  • Honduras, Set dates: September 26 - 30 at Zamorano Univ, Latest TLUD & institutional stoves; Emissions measurement via PEMS, Totally in Spanish

Other prospects: Brazil, Andean region, China, Southeast Asia, West Africa, .Western North America, etc. BEF will consider additional locations that provide strong local support. Contact: psanders at

3. Every BEF Camp has at least two "content leaders" certified by the BEF for presentation of its state-of-the-art core curriculum, ensuring substantial experience, dialog and cutting-edge challenges for all participants. BEF will be training and certifying in 2011 additional expert "content leaders" authorized to conduct as many official BEF Gasifier Stove Camps and BEF CHAB Camps as needed anywhere in the world.

4. Each BEF Camp has a local coordinator for facilities, materials and interaction for inclusion of special topics of interest to stove and CHAB enthusiasts in that regional area. Each BEF Camp has sufficient differences and updates to merit repeat attendance.

5. BEF Camp sizes are limited to 15 to 30 participants (subject to change in special circumstances.) Costs/fees (including materials) are expected to be between US$250 and $500, depending on specific arrangements for each camp. (Excludes transportation, lodging, and most dinners.) BEF Camps may have sponsors that alter costs, content, and selection of participants.

BEF statement about its intentions and structures of its BEF Camps.

BEF Camps with Gasifier Stoves and CHAB Themes

The Biomass Energy Foundation (BEF) is launching around the world in 2011 its instructional five-day events called ?BEF Camps?. Each BEF Camp is a structured learning experience, where the technical foundation, practical skills and fabrication methods of constructing biomass-fueled devices are taught.

As the Chinese Proverb notes, "Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime." BEF feels the same applies to gasifier stoves: Provide one stove or only one stove design limits the consumer to that unit. Instead, teach the principles of micro-gasification and the people everywhere can produce stoves appropriate to their unique needs and circumstances, such as fuels, foods, and cultural-economic situations. BEF aspires to teach how and why biomass-fueled devices function and how to apply these design principles to a broad range of circumstances, initiating a sequence of knowledge exchanges that reaches across peoples, cultures and situations.

A typical BEF Camp starts with a social gathering Sunday evening, followed by two days of structured learning, building and burning. Typical days are divided between discussing combustion concepts, learning fabrication techniques while building small prototype devices that demonstrate the concepts, and operating the devices on both supplied and locally available fuels. Evenings are either social gatherings (including one meal prepared on the stoves) or additional time to fabricate and operate biomass-burning devices, collaborating in small groups of 2 to 5, and learning from insights and experiences of fellow participants.

The final two and one half days feature focused applications of the acquired skills to individual circumstances dictated by personal interests, unique fuels or culturally specific opportunities (often pre-announced for each camp). The instructors work in conjunction with small groups of "makers and testers", with supplies available to prototype concepts and verify designs.

BEF Gasifier Stove Camp focuses on the theory and operation of Top Lit UpDraft (TLUD) gasifying stoves, based on the pioneering work of Dr. Tom Reed, Mr. Paal Wendelbo, and Dr. Paul Anderson. Covered in depth are the underlying concepts of two-stage combustion "separated-in-space," primary and secondary air supplies, and tuning of the performance of specific designs. Building on the foundation of a clean and fuel-flexible source of heat, the fundamentals of heat transfer to cooking applications and designs of "culturally compatible cooking environments" are covered. Group projects are generally directed to the utilization of unique biomass fuels (seeds, dung, grain hulls and agricultural residues) or adapting stove designs to locally available materials and construction resources.

BEF CHAB Camp addresses the broader challenge of "Combined Heat And Biochar", where devices strive to generate useful heat, perhaps for cooking but also for other heating applications, and concurrently produce biochar. Compared to typical biomass ash, biochar has residual value as an additive to soil or use as charcoal, thereby greatly improving the attractiveness and economics of consuming biomass. The multiple challenges of clean useable heat and effective biochar shape the camp activities.
