<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>First let me reiterate the warning that TLUD charcoal
making is not CO2 negative unless you have also a use for the heat GENERATED
in the pyrolysis gas fire. Wood is 50% carbon, and if you get a 20%
yield of charcoal, you have put 30% back in the air as CO2 sooner than if the
wood rotted. So 1 ton of wood gave 400 lb of charcoal and (1600x44/12)
5.87 tons of CO2 into the atmosphere.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Unless you cook or generate electricity with the heat, in
which case you are doubly CO2 negative by replacing propane or other fossil
fuel for cooking!<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><><><><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>I like the idea of the blanket, but not the $1500 it would
cost and the time it would take to develop. How about
TURF.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Classic charcoal at the time of Napoleon ( he burned down
the forests to make cannons) involved stacking many cords of wood around a
central chimney made of poles and covering it with turf, leaving a smoke hole
at the top. Small air entries were made at the base and fires lit.
For quite a while the smoke was white as water vapor was expelled amd
the wood dried. Then the smoke turned yellow, as pyrolysis began, and
finally blue when the charcoal was burning. Then seal the bottom up
tight and wait another few days for it to cool. Strip off the turf and
you have a beautiful pile of charcoal. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>I have been tempted to replicate the above method on a
small scale in my back yard next April when we are allowed to burn.
But I would substitute TOP LIGHTING with burning off of the pyrolysis
gases as they are formed and regulation of the burn rate by adjusting the air
inlet holes. Make a TURFTLUD.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>I hope you will discuss this with your friends at UW.
I would even be willing to fly out for a meeting and maybe small tests
if you have a secret burn spot. <o:p></o:p></P></DIV>

<DIV>
<P class=MsoNormal>Dear gassers and Stovers<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal> <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal>Using any size TLUD device including an open PYROMID, and
any junk biomass, we all have easy access to as much charcoal as we could
ever need, for the first time in history.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal> <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal>Furthermore, Hugh McLaughlin tells me that, while it's
not true activated charcoal, made with steam or CO2 at 800C, it has
significant absorption capacity (iodine no 400?) since it is made at 500-800
C. I hope Hugh or Frank will comment. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal> <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal>So we really have no excuse for cleaning up TLUD gas if
we wish to. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal> <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal>I'm waiting for a good analysis of TLUD gas. I
suspect after cleaning it will have significantly more energy than the
typical 5.5 MJ/m3 or 150 Btu/ scf of downdraft Woodgas, since the air fuel
ratio for pyrolysis is only 1-1.5, rather than the 3.5 for complete
gasification of the cellulose lignin package that is wood. So, as a
first guess, with 1/3 the A/F ratio, I'm guessing 3x the energy content, of
4.5 MJ/m3 or 450 Btu/scf. Compare to natural gas at 1000 Btu/
scf. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal> <o:p></o:p></P></DIV>

<P class=MsoNormal>I'd sure like to see some comments from all you practical
