[Stoves] Stoves Digest, Vol 2, Issue 26

Hiya,

That study was 2005, the most recent WHO report said approximatley 2 million per year, in November 2009.

Find it here http://content.undp.org/go/cms-service/stream/asset/?asset_id=2205620 , or go direct to their site 

The UNDP/WHO 2009 report, The Energy
Access Situation in Developing Countries, A Review Focusing on the Least
Developed Countries and Sub-Saharan Africa, can be downloaded from http://www.undp.org/energy

The problem is that these figures from the WHO are extremely conservatve, and only relate to direct death caused from cooking smoke as referenced in multiple independant studies. Primarily this is pneumonia in children under 5, COPD and lung cancer (especially with coal). It does not, however, include the related deaths. So, for example, if your TB is made significantly worse by smoke inhalation and you subsequently die, this death is not recorede in absolute terms or in loss of years as a smoke consequence. Other involved studies are not included in these figures as they are simply not backed up by enough other studies, there must be 15 - 20 studies shown hence only 3 main related sicknesses. Athsma, cateracts, still births and perinatal mortality as well as other respitory and heart issues are all linked by study, but not backed up enough to have as published figures. See page 48 of the above paper. Cateracts, for example, will cause significant loss
 of welfare in a community, but rarely kill...and so on. The figure, all inclusive could be as high as 6 million per year, but that is difficult to prove exactly.

Hope this helps, depressing as it is.

  Philip,

      Outdated statistics. Not 1.4 million.  The W.H.O. quotes 1.6
    million every year.

    http://www.who.int/mediacentre/factsheets/fs292/en/index.html

        Indoor air
          pollution and health

        Scope of the
          problem
      "More
                    than half of the world’s population rely on dung,
                    wood, crop waste or coal to meet their most basic
                    energy needs. Cooking and heating with such solid
                    fuels on open fires or stoves without chimneys leads
                    to indoor air pollution... 

                         Exposure
                            is particularly high among women and
                            children, who spend the most time near the
                            domestic hearth. Every year, indoor air pollution
                            is responsible for the death of 1.6
                              million people - that's one death
                            every 20 seconds."

We need experiments for high school science students to make and use
biochar. 

Kelpie and Christa have provided good instructions for small biochar stoves
for students wanting to learn about biochar:

How to Make the Dome School Biochar stove, Kelpie wilson

.pdf

Basic Design Principles of the Pyrolytic TLUD Gasifier Stove in 2010
 Bq
Demonstrations, or "How many sausages can you grill in the process of making
30g of biochar? Christa Roth

http://terrapreta.bioenergylists.org/files/2010%20biochar-bq%20demonstration
%20by%20Christa%20Roth.pdf

What student projects can demonstrate the ability of biochar to capture
nutrients and retain them for plant growth?

Nutrient capture: are there simple leaching or column tests where students
can filter a known concentration of fertilizer elements through samples of
soil with and without biochar and directly measure the concentration in the
filtrate using something like a specific ion electrode or conductivity
tester e.g. K or nitrates, or heavy metals like  Pb, or Cd?

Greenhouse/pot tests: can the students
 then test the same media with and
without biochar in pot tests?     

A students recently asked if there is a way that she can measure the amount
of carbon in biochar that will be available for carbon sequestration. Any
examples or ideas?

Thanks

Dear Tom

I am pretty sure the source is Kirk Smith. Another person who is very up on
the subject is Jostein Nygard jnygard at worldbank.org who has made
calculations for
 whole countries including China.

It is possible Steinar Larssen stlarssen at hotmail.com is quite au fait with
backgrounders and even the calculation methods.

Regards

Crispin

All,

Where are there studies that document the illness and loss of life from
cooking over open fires? We all quote the 1.4 million deaths per year but
what is that information based on? Where is the source documentation? Is
there information to document improvements from stoves?

Dear Crispin,

Is a coal fired hydronic heater with flue pipe out of line?

Best regards,

Jeff

Why is no one talking about chimneys
 that get rid of the CO safely? And
doesn't the addition of a chimney change the dynamics of any stove?
