<p class=MsoNormal>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>

<p class=MsoNormal>I seem to have received this by mistake perhaps? I make
charcoal for cooking food, not so much growing it. <o:p></o:p></p>

<div>
<p class=MsoNormal>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
