Philip, Lloyd

Good references. Thanks. 

I found 1.3 million in:

Table 1: Ranking of selected risk factors: 10 leading risk factor causes of
death by income group, 2004
in
WHO publication " Global health risks: mortality and burden of disease
attributable to selected major risks"2009
at
http://www.who.int/healthinfo/global_burden_disease/GlobalHealthRisks_report
_full.pdf
http://www.who.int/entity/healthinfo/global_burden_disease/GlobalHealthRisks
_report_references.pdf
http://www.who.int/indoorair/en/

It's not clear how it builds up to 1.6 million that Lloyd found in
http://www.who.int/mediacentre/factsheets/fs292/en/index.html

WHO statistics have data for solid fuel risk factors for only one year.
World Health statistics 2010, WHO.  

It's like to take some study. 

Tom

It is a world health organisation publication of ~2003, looking at the
sources of mortality worldwide.

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

http://greenyourhead.typepad.com/files/how-to-make-dome-school-biochar-stove
.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

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?

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

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?
