Thanks for linking us to the report from Georgia Institute of
Technology. Dated April 2011. So most of those students are
probably graduated by now. I think Marc Pare might have known
those students and Professor Colton.<br>

I really like the graphics that show the differences in the
devices for producing biochar. See pages 6, 9, 10, and
especially pages 51 and 52 (pages of the digital document, not the
numbers printed on the sheets in the report). The "Story Board"
is very well done for understanding what is happening in each of
the 3 variations shown!!!<br>
<br>
Some notes:<br>
1. Page 51 story board shows the method that Peter Hurst used in
his video. The story board well illustrates why this method does
NOT work very well. That is: TLUD heat starts at the top, which
is not the right place when you are trying to heat a retort.<br>
<br>
2. Page 52 shows the John Rogers design of a TLUD in a barrel.<br>
<br>
3. The students eventually did a retort with a fire at the
bottom see page 10.<br>
<br>
4. Analysis: The students watched two YouTube videos, one by
Peter Hurst and one by John Rogers. Fine. But there is no
indication in the report or in the References of any examination
of what preceded and influenced the work of Hurst and Rogers.
Result was that they appear to have missed some crucial
components. Specifically there seems to be no use of the
"concentrator disk" in the TLUD experimental unit, a crucial
component devised separately by Wendelbo and Anderson. The Rogers
unit functions but is not optimal.<br>
<br>
5. Now that the report is getting some wider circulation, I hope
that those who read it will not take it as gospel. Users and
experimenters should search the literature about the smaller TLUDs
and about biochar barrels etc. that several of us have presented
in earlier years and have been presenting recently at conferences
such as ETHOS-2012 in Kirkland/Seattle and the USBI-2012 in
Sonoma. <br>

Personally, I like the bottomless-biochar-barrel for many
situations and for its ease of construction. One was prepared
and used twice at the recent First Biochar Summer School, in
Potsdam, Germany. <br>
<br>
A LOT OF WORK STILL NEEDS TO BE DONE ABOUT BARREL-SIZE TLUDS AND
BIOCHAR PRODUCTION.<br>
