<DIV class=moz-cite-prefix>Stovers and Biochar folks,<BR><BR>Our thanks to Teddy
in Kenya for his comments below sent to Lloyd H. and a few others, and
especially for the link to his blogspot (well worth seeing). It
shows that he has successful creation of char from coir (coconut
husk). But do note that his kiln is ignited at the bottom, and then
has the coir put on top. That clearly seems to work, and I see that
as mainly a "retort" style of pyrolysis, with the heat (and no oxygen) rising
from the bottom to pyrolyze the coir. So, if you are only trying to
make char (or biochar) from coir, consider Teddy's method. Maybe
Trevor can replicate this in the Marshall Islands, or others do it wherever
possible. Considering the tons and tons of coir around for free, and
the need for biochar for soil improvement in the "coconut-belt" of the world,
this could be quite significant.<BR><BR>Clearly it is not TLUD processing, so
the question still remains if TLUD pyrolytic methods and temperatures can
sustain the secondary flame for cooking and yield char.<BR><BR>Paul<BR><PRE class=moz-signature cols="72">Doc / Dr TLUD / Prof. Paul S. Anderson, PhD

<DIV dir=ltr>Dear John and Llyod
<DIV> </DIV>
<DIV>I seem to have received this by mistake perhaps? I make charcoal for
cooking food, not so much growing it. </DIV>
<DIV> </DIV>
<DIV>But as you raise the questions of charcoal for filters - I have
certainly (anecdotally) noticed that there is a huge differance in various
charcoals - even from the same plant. I.e coconuts - the nut becomes a hard
shiney charcoal with few pours and the coir becomes very sponge like
and does not burn so well. <A
