"No smoking" while cooking through use of efficient good stoves. There is a need to facilitate 1 billion good stoves. This calendar with pictures reminds us this challenge.

The Project was concerned with the evaluation of the energy efficiencies of commonly available biomass
fuels in Uganda in a “Champion-2008” Top Lit Updraft (TLUD) gasifier stove. Selected biomass fuels included; Eucalyptus wood from plantations, maize cobs (agro-waste), papyrus, spear grass, noncarbonized briquettes (agro-waste and sawdust) and off-grade jatropha seeds. Moisture content
measurement of biomass fuels was determined using oven-dry method. The energy efficiencies of the
biomass fuels in the “Champion-2008” TLUD gasifier stove lied between 12 and 19%. Maize cobs had the highest energy efficiency of 18.40% and spear grass had the lowest of 12.64%. Maize cobs and papyrus were not significantly different from Eucalyptus wood. Non-carbonized briquettes and off-grade jatropha seeds had a higher operation time compared to the rest of the selected biomass fuels though faced with a problem of higher starting time but able to perform when started. The results obtained indicate that a variety of biomass fuels in Uganda can perform well in the “Champion-2008” TLUD gasifier stove, thus the need for adoption to combat deforestation problem.

Leslie Cordes, Global Alliance for Clean Cookstoves December, 2010

Dear Colleague:

We would like to invite you to participate as a Core Member of the Technology and Fuels Working Group of the Global Alliance for Clean Cookstoves. These working groups will provide an excellent opportunity for Alliance partners to help shape the future direction of the Alliance as we define our strategic vision for the next few years, and we welcome your active input and engagement.

The Alliance was launched in New York City this September with a commitment to saving lives, improving livelihoods, empowering women, and combating climate change by creating a thriving global market for clean cookstoves. Since the launch, we have begun a range of activities to help achieve our ambitious interim goal of having 100 million homes adopt clean and efficient cookstoves and fuels by 2020.

As a critical step toward this ambitious undertaking, the Alliance is establishing nine working groups charged with identifying and prioritizing a suite of critical steps necessary for the sector to reach a ‘tipping point’. These outputs will form the basis of both a public ‘Clean Cookstoves Sector-wide Priorities Report’ (or less glamorously, a ‘to-do’ list) as well as the long-term strategic plan of the Alliance. We envision these documents will serve in a sense as the first-ever sector-wide roadmap on how to take clean cookstoves to scale in the developing world.

Why We Do What We Do

From Art's Preface:
Buenas,
Just a quick note from Costa Rica. Our Estufa Finca (a large TLUD) team is two weeks into preparing for a 10 week pilot project. Working with SALTRA and a program at the Universidad Nacional de Costa Rica, we will be installing 50 , locally produced stoves with migrant coffee bean pickers.

I want to side with Paal on this very important point. Our stoves can have the best looking numbers in the lab. But if people won't use them it doesn't make much difference does it. The stove design we are using has been jointly developed by myself, my Central American partners (esp. the women who are building them APORTES), but most esp. by listening very carefully to the people who we hope to benefit. Much of the feed back has been in regard to the fuels issue. These people do not have access to chips or pellets, we are not going to get them to make briquttes, etc... so instead we have given them a fuel chamber easy to load with sticks, sugar cane bagasse, etc. and powerful enough to cook for the typically large extended families. This process stared in August 2009, there are currently 20 of our stoves being used in CR and Nicaragua, the feedback has been very positive. The pilot project is simply a continuation of that process. We are going to be using the KPT version 3.0 protocol, with some customization to monitor 30 stoves. All of us on the team are looking forward to adding more TLUD based stoves to our line. But this approach is showing us what will get used in the real world.
