JED,

Truly awesome!!!!!!!!!    [Based on very little information, but he 
tells us truly important info about fuel and boiling time and combustion 
technology.   This truly looks promising.]

I suspect that you are on the verge of a major shift in cooking 
stoves.   Your attachment with photos in your original message should be 
seen by all.    It will be soon placed on the www.drtlud.com   website.

What I am reading and interpreting is this:

1.  Abundant supply of a fuel that is appropriate in size, energy 
content, moisture, etc.   Literally an agricultural "refuse" for free or 
for the cost of transport.   Producers will start selling it, but it is 
already UNDER the price of other fuels, so the price will only rise to 
the level that the market will bear.

2.  A CERAMIC / MUD / CLAY stove, made by a master of clay stoves. We 
would like to know the cost of the stove.   And how easily can it be 
made ?    Importance of clay is in next item.    And it should be able 
to handle numerous other appropriate biomass fuels, but doing just one 
(pili nut shells) is sufficient for starting and establishing what can 
be accomplished.

3.  You operate in TLUD mode (correctly characterized by the downward 
migratory pyrolytic fron MPF).   And then you continue to burn the 
created char while adding (please explain where and how) additional 
fuel.   The result is the high heat in the char-bed, but without the 
metal parts that are damaged by high heat.   Ceramics to the 
rescue!!!!   Continuous burning.

4.  Plus you are demonstrating the making of light.   Very nice.

Best wishes.   Please tell us more.    And about the important issues of 
user acceptance.   Many of us are willing to be of assistance.   In some 
ways you are only scratching the surface of what you are 
demonstrating.    Congratulations.

And are you going to the GACC Forum in Ghana in November 10 - 13?
