Paul Olivier, September, 2011

Paul Olivier is working from Vietnam, and had put together a comprehensive pdf article explaining the benefits of using TLUD and other gasifier stoves to avoid cooking smoke and create biochar. Cooking Smoke is a major health problem in both rural and urban areas in Vietnam and many other parts of the world, and improved stoves that can also produce biochar can also help urban and rural people retain nutrients in their soils, and reduce pollution.

Kerosene lanstove is a device which simultaneously produces very high quality of light, cooks a complete meal for a family of 4-5 people and boils 10 liters of water. The word lanstove has been coined by our Institute NARI ( ). The kerosene combustion is excellent with CO levels less than 3-4 ppm and particulates are within WHO limits. Lanstove is as convenient as LPG stove cooking and has been tested in rural households in India.

There are 3 billion people in developing countries that rely on solid fuels for almost all of their cooking. The question can be asked how many of these over 800 million households cook with an improved stove? The answer comes from a new study by the World Health Organization (WHO) and the United Nations Development Programme (UNDP). Like any good mystery story you will have to skip to the end for the answer. All I will say is that the results may surprise you.

Doug Barnes Complete Article: Improved Stoves in Developing Countries by the Numbers

The statistics in Doug Barnes' article are drawn primarily from this WHO United Nations report, which has some Great Information about Biomass Energy use and the Health Impacts of that use.

The "Energy Access Situation in Developing Countries - A Review focusing on the Least Developed Countries and Sub-Saharan Africa" report draws attention to the energy access situation beyond the conventional focus on electricity, especially in poorer developing countries where access is the most constrained.

Main topics covered by the report include:

  • Energy access situation in LDCs and Sub-Saharan Africa, including access to electricity and modern fuels
  • Fuels and improved stoves used for cooking in developing countries
  • Health impacts attributable to indoor air pollution from household use of solid fuels for cooking and heating
  • Developing countries with modern energy access targets, and
  • An analysis of different energy access scenarios for 2015, to estimate the progress in energy access that will be needed for the achievement of the Millennium Development Goals (MDGs)

Some Key Points from the report

Access to modern energy services is still low in developing countries and
this lack of access disproportionately affects Least Developed Countries (LDC)s and Sub-Saharan Africa (SSA)

  • Three billion people, i.e. almost half of humanity, rely on solid fuels –traditional biomass and coal – as the available modern energy services fail to meet their needs. More than 80% of people in LDCs and SSA primarily rely on solid fuels, compared to 56% of those in developing countries as a whole.
  • Two million deaths per annum are associated with the burning of solid fuels indoors in unventilated kitchens. Children bear 44 percent of this toll, and among adults women bear 60 percent of the burden.
  • Almost a quarter of the world’s population still lives in darkness; over 80% of them in South Asia and SSA. More than 70% of people in LDCs and SSA lack access to electricity, compared to28% of those in developing countries as a whole.

Hola companeros,

Mandanadose un reporte algo grande, pero de interes sobre el trabajo que hice Rogerio y Winrock introduciendo una estufa tipo Justa pero modificado para Peru, la Inkawasi


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!

The Kenya Seeds Of Change initiative aims to contribute towards national afforestaion by land owners through the countrywide sales of inexpensive tree seeds and the promotion of direct seeding woodlot establishment. Seeds are by far the best method of promoting wide scale tree planting in Kenya. These are some of the benefits from the direct planting of tree seeds compared to planting seedlings;

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”
