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.

Smoke's increasing cloud across the globe
Practical Action June 16, 2006


It is in the world’s poorest regions that smoke is a major threat, including China, India and sub-Saharan Africa. On current trends, 200 million more people will rely on these polluting fuels by 2030. Women and children are exposed for up to seven hours a day to pollution concentrations 100 times and more above accepted safety levels. There is ample medical evidence that smoke from burning biomass fuels leads to killer diseases, such as penumonia, chronic bronchitis and lung cancer.

How to characterize emission factors?
Tami Bond, Bond Research Group, University of Illinois Urbana-Champaign February 2006

How to characterize emission factors? Short story:

- For traditional stoves, we have some, they vary a lot, and we don't always know why they vary. It's probably a combination of wood, moisture, and practice, and who knows what else.
