[Stoves] ETHOS 2013: Where is the New Data on Stove Performance in the Field?

Mon Nov 26 10:19:46 CST 2012

Good idea. We can work on it over the next few of weeks. Sorting out the
objectives and use of tests, methods and formal protocols would be the place
to start.

Tom, 

Sounds like a great idea and I'm sure by the flurry of writing this weekend
that it would attract a lot of interest. I also know that there are a lot of
questions that need be answered.

Maybe a format that could work would be a panel for the whole group followed
by a set of talks for those who wish to continue the discussion. Can you put
together a panel and a set of talks that would represent the divergent views
on this topic?

Dean - any thoughts

Thanks

Mark

Mark,

You have listed a number of standards and protocol topics. Now that GACC
exists have we made any gains on the science side? Where is the data?  We
should be generating good field data by now. I don't want to just hear
reports about what people have decided in political committees that nobody
seems to be able to attend or vote in.  

I would like to see a critical review of the testing protocols and methods
with regard to the key metrics and emissions. For example, the protocols to
date have made assumptions about heating values of fuels and residues ash
and charcoal that I have always felt were just placeholders until someone
with larger research budgets could validate them. Determining the amount of
energy left in the ash or charcoal is a good example. I often get asked what
value to use for the remaining ash/charcoal. I haven't seen a test where the
remaining charcoal/ash has been directly tested for ash content and heating
value.

Testing the benchmarks. Do the benchmarks that were derived several years
ago make sense now that we have improved tools for measuring stove
performance or do we get the same numbers because we're using the same
tools? Do the benchmarks tell us anything about stove performance in the
field? Do stoves preform in the field in the same relative way they are
shown to perform in the lab or are some stoves much better than others (or
much worse) when they are used in the field? Are the stoves designed to the
test (e.g. WBT) or to the use in the field? Do some stoves perform best when
they are tested in the lab and fail in the field? Or, are we even testing
for this?

Field applications. Are our tools and metrics of any use for improving stove
performance in actual use? If so then how are projects in developing
countries using these tools to improve their fuel use and health? How do
local, nation, or regional stove projects use these tools to improve their
stoves, or do they just ignore them?

QA/QC. When a program buys container loads of stoves how do we know that
they perform within the expectations created by the test results? Do any of
the manufactured stove suppliers test the quality and performance of their
stoves on a regular basis? Is there any monitoring?

How has testing been used for different fuels? I was inspired this week by a
photo from Mexican which a construction worker was using an LPG burner in an
eCocina stove (Stove Team International) because it substantially reduced
his LG use. Can we compare fuel consumption for different fuels? How good
are our fuel consumption metrics?

Health. We still do not have proven direct correlation between stove
emissions and heath. Most of the data seems to be recycled. Are there new
health studies? Has GACC and the many supporting organizations funded any of
the fundamental health studies that every year Jay Smith tells us are
lacking?

These are some of the questions that I would like to see addressed at ETHOS.

Looking forward to another productive ETHOS.

Thanks

All,

It's that time of year again! We're starting to get the activities together
together for the ETHOS conference. The conference will be January 25 - 27,
2013 in Seattle. Proposed discussion topics include

- Update on the Global Alliance and their activities

- Standardizing Reporting on IWA Indicators

- Stove Performance Inventory, Sharing Public Data, and Establishing Common
Data Formats

- Update on ISO Process

- Updates on Protocol Developments (including possibly charcoal, plancha,
batch-fed, durability, finalizing WBT from public comment period)

Let us know what else you would like to talk about. A lot is happening and
I'm sure it will be as exciting as ever. I'd appreciate having your ideas on
topics and panels by November 15.

Abstracts for papers and talks are due January 1.

For more details, to register, and to submit your abstract the conference
web site is http://www.vrac.iastate.edu/ethos/conference.php.

Please send your ideas directly to Dean and I.

Best regards

Mark
