I want to share with you some data abaut solar cookers in europe!
Information from: Solar cooking Atlas ( and ID Cook (

**What is a solar cooker?**

It is not so complicated, a solar cooker, or solar oven is a box which uses the energy of sunlight to cook meal or sterilize.

The GTZ project “Poverty-oriented Basic Energy Services (HERA)” has launched a comprehensive guide on carbon markets for improved cooking stove projects. The guide offers an overview of the various steps in the project cycle of CDM and Gold Standard projects, describes existing methodologies, and addresses the most critical issues in project development.

The guide is updated on a regular basis and has recently been supplemented with the latest changes in the CDM methodology AMS-II.G. HERA is closely following the ongoing discussions for a second revision of the methodology which might take place in April 2010.

Your feedback and project experiences are highly welcome to keep the guidebook up to date!

A couple of the presentations from the ASEAN-US NEXT-GENERATION COOK STOVE WORKSHOP, November 19, 2009.

One is a great study by Dr. Modi of Columbia University of several stoves in Tanzania, and the other is some useful info from Tami Bond. Kirk also gave a very useful presentation, but unfortunately it was not included in the proceedings.

Teaching Renewable Energies and Sustainability in the School of Diogo Vaz (São Tomé, Africa)

This work aims to show how sustainability and renewable energies could benefit a rural area of Africa (in São Tomé) by means of using solar energy and biogas. Applying these technologies requires ingeniousness and little founding, the favourable outcomes are becoming less dependent of fossil fuels (wood, coal and gasoline) while saving time and, more importantly, the forest. We have taught how to design, build and operate systems for cooking, lighting and water-heating that use renewable sources of energy.

New Princeton Report on Climate Impacts of Black Carbon

Princeton University has just published Black Carbon: A Review and Policy Recommendations and Frank Norcross (one of the authors) sent me an early but final copy – you’ll recognize that many of the people acknowledged are from our stove community, with Tami Bonds contributing very obviously throughout. The report ascribes 18% of black carbon (BC) emissions to residential biomass burning (inefficient home coal and petroleum stoves add additionally?), and differentiates between combustion processes’ “organic carbon” and “black carbon” (à la Tami’s and Chris Roden’s presentations at ETHOS) – contained burning has the potential for climate warming via BC while open burning (of forests and savannas) may induce cooling effects because the organic carbon particles scatter sunlight.

Appropriately, the recommendations for reducing the impacts of stoves (Chapter 4) includes the implementation of more efficient ones, with better interventions and monitoring to increase acceptance rates, and clearly demonstrate that they are being used as they are designed to be; as usual we have out job cut out for us. Biochar is discussed as well, as a mitigation measure – assuming that charcoal product is “clean” I expect. Whatever your opinion of the possible present/future impacts of we multiplying humans on climate change, this is excellent reading and a good review of the present knowledge as it pertains stovers.

Introduction to Gold Standard/Carbon Credits

Gold StandardGold Standard

There has been a lot of interest recently in carbon credit financing for improved stove projects. Since 2006, stove organizations have begun to receive funding from carbon credits. The Gold Standard has just published a set of protocols formalizing how stove projects can prove the lowering of emissions. Large financial institutions, like Climate Care/JP Morgan, are now participating in the relatively new market.


I wish to promote some of your product especially the stove and its boi fuel in my country as part of my contributions to the charity home. how do i go about this? My name is Dada Ayobami, a Nigerian, Manager of Alugoke nig limited(hydro-works)
