[Stoves] Stove testing with and beyond the WBT

[Ron]

Stoves, Crispin, Paul, Ranyee

   1.  Too late for a full response;  more coming.

   2.  I like much here, but think you have thought this through with a process that undervalues the production of char.  In particular slide #15 I feel needs modification on both sides.  The standard efficiency formula (char energy subtracted in the denominator) greatly undervalues (not overvalues) the char.  Explanation tomorrow. But briefly, I want to see the char equally valued, so one adds together the carbon neutral and carbon negative production efficiencies.  This is why I went to the GACC and got 10 minutes on this topic.  
     Char-making stoves are getting the shaft now.  I think. (need help) other country procedures are doing it my suggested way.

  3.  Slide 15 references a GEF approach which I couldn't find just now in a quick Google.  Can you point me in the right direction?

4.  I'd like to do all the computations myself, but will need the assumed fuel and char dry energies, the fuel moisture content, and maybe more.  Can you give me these or point in the right direction?

5.  Paul:  I couldn't see a one-pager from Crispin in yours or on your site.

It is my hope that we can create an agreed scientific platform on which to perform a wide variety of culturally relevant tests that provide normalised results. The Toolbox is a collection of mathematical and cultural tools for measuring performance over a wide range of conditions in diverse cultures.

The cultural appropriateness of stoves is often considered only after a technology has been ‘invented’. Being relevant is a major consideration to marketing campaigns. Sustainability is strongly desired and being sustainable means being simultaneously an improvement and desirable from cultural, economic and environmental points of view. It is by definition a Triple Bottom Line adventure.

Although it is an inadequate description due to the fact it is brief, I have attached a Powerpoint presentation giving some of the motivating factors for creating the Stove Testing Toolbox and what can be expected from it.

While this is implicit in many tests, this divides each task conceptually into discrete segments and creates validated processes that normalises data in order to permit a wide range of tests to give comparable results. It does not specify any tasks, it specifies how a task of that type should be done to get a relevant and correct output.
