<DIV><BR></DIV>Dear Kirk, Paul and all,<BR><BR>Kirk: thanks for circulating
your hypothesis. This seems well-founded.<BR>Paul: measuring long-chain
hydrocarbons / tars is part of the planned project of PhD student Thomas
Kirch.<BR><BR>The intention is to measure the tars fairly soon. The catch is
that our existing micro-GC isn't suitable for this, and finding someone who is
willing to put our tars in their GC-MS is proving difficult. Until we get
funds to buy our own, any suggestions for other ways of characterising the
tars?<BR><BR>Cheers,<BR>Paul<BR><BR>

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)

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>
