[Stoves] Specifics about advancement of TLUD stoves Re: fan expertise?

[Paul Anderson]

Dear all,   This is a different and more specific reply to Otto's message.

I see four things that will greatly advance the position of 
micro-gasifier stoves, specifically the TLUD stoves.   I am working on 
all four of them.

1.  Prove that stove users will accept TLUD gasifier stoves (at 
reasonable price, but this is not about price.) and (with a reasonable 
supply chain for appropriate fuels, but this is not about fuels) :

We lack meaningful studies that show that TLUD stoves (when available 
and with fuels available) are accepted by "typical" cookstove users in 
any significant segment of the population.   We need some documentation 
that xx number of TLUD users (out of yy number of households that 
seriously tried TLUD stoves) are still using the stoves zz percent of 
the time for their cooking, and this is over time periods that are 
checked again and again each few months.    Comments from users should 
be reported.

Start small, and do it well.   The money for the bigger studies will 
follow success with the small numbers.    This is NOT about sales.   
This is about sustained usage.

We are working on this topic at Awamu in Uganda with the Quad TLUD 
stove, but no results to report at this time.    Is anyone else doing 
such studies?

2.  Compilation of past results and further data collection about 
emissions and efficiencies of TLUD stoves.  Some TLUD have had major 
success.   And others "suck".   Which ones and why?   We seek data from 
the stove testing centers.   We also will do further work at Stove Camps 
in the coming 3 months.

3.  Prove the capacities to produce sufficient numbers of TLUD stoves 
with excellent functioning.   The response must be credible for numbers 
of many 10s of thousands for stoves per year.   20 tinsmiths seated in a 
factory is not sufficient proof.   Prof. Nurhuda has shown that metal 
stamping can produce his TLUD stoves with good quality.   I do not doubt 
that capacity worldwide could be sufficient when demand is there, but 
with the goal of creating in-country jobs, for most situations "proof" 
is still not in hand.

4.  Bring the price below US$10 for the low-end products that are still 
functional about emissions and efficiencies.    I am working on this and 
I hope to report about it at the July stove camp at Aprovecho where TLUD 
stoves are a focal issue.

Note that I did NOT add on having different TLUD stoves such as the ones 
with fans like Ron is discussing.   When they become available, that 
will be wonderful.  But then such stoves will still need to be 
considered regarding # 1 and #2 and #3 above. They might be the 
breakthrough for gaining acceptance, or lower emissions, or whatever.
