<DIV><FONT size=2 face=Arial>Thank you for your response. I am glad
that you believe it is worth following up on the hypothesis. It
occurred to me when I remembered something Julien Winter had
said. </FONT></DIV>

work!!!! Stove Summit, Stove Camp, assisting Dennis (who then won
the Cat Pee award), and cooking with Flip. It is always a pleasure being
with you.<BR><BR>The hypothesis (explanatory document) is well done. All
serious stove researchers should read it. Where is this document being
placed for public access. I offer to place it at
the drtlud.com website. (Send your reply
to James Schoner directly or via the Stoves Listserv; I will be in Mexico for
the next 13 days).<BR><BR>Hypotheses are statements that ask to be
confirmed. The folks with the scientific equipment can now step in and
see if the long-chain hydrocarbons are indeed breaking up when and where
indicated by the hypothesis. Good if that could be soon, but I expect
not. In the meantime, the excellent low emissions (which are facts, not
hypotheses) speak for themselves.<BR><BR>The needed scientific studies would
help answer several questions such as whether all three steps (levels) are
needed to accomplish the low emissions and the ability for turn-down to low
fire.<BR><BR>About turndown such as when cooking in Flip's oven, a different
solution is to have a second gasifier reactor (fuel chamber) that has a
smaller diameter.<BR><BR>Keep up the good work!!

<DIV><FONT size=2 face=Arial>All,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>Talking about stoves at the InStove
Stove Summit and Aprovecho Stove Camp made me think through the workings
of our Wonderwerk TLUD-ND. I needed to create a
working hypothesis of why it burns as cleanly as it does. Attached
is the hypothesis. It may not be completely correct, but it does
provide an explaination, or at least a place to start an explaination.
There is a lot that I don't know about
this burning method and a lot of work left to be
done.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>At Stove Camp, Sam Bentson, Aprovecho's
lab engineer offered to help me probe into the pressure
variations in the stove. I was sadly involved with too many
things to take him up on it. My loss! What I did do was to
support Dennis, a visiting student from China, in his development of a wok
support with skirt and chimney. </FONT> <FONT size=2
face=Arial>He tested it on top of the latest Wonderwerk TLUD-ND stove and
the results were impressive. He made several adjustments to the
dimensions which seemed to improve its performance even more. He
required only high power and no turn-down.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>After Stove Camp I visited with Jon and Flip
Anderson. We put an older Wonderwerk TLUD-ND under one of their
clay ovens, and baked a cake. It required two fuel (vertically
arranged split sticks of an unknown variety of hardwood) loadings of the
stove, the first to heat the oven and give about 30 minutes of baking and
the second finished the 1 hour baking time. This showed the need for
turn-down capability for oven baking. The latest Wonderwerk
stove, which I had left at Aprovecho, would very likely have done it
with only one load of fuel, because of better turn-down and more efficient
burning.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>I hope you enjoy looking through the
hypothesis.</FONT></DIV>
