<DIV><FONT size=2 face=Arial>I find your observations about fuel preparation
very interesting. I think they are very important in understanding the
significance of one of the obstacles to fuel preparation for stove
systyems.</FONT></DIV>

<DIV><FONT size=2 face=Arial>In an extreme Poverty Economy, such as exists
for very poor people who are struggling to attain the basic essentials of life,
about the only asset and resource these people have is time and their labour.

<DIV><FONT size=2 face=Arial>Stickwood can be burned directly in a Rocket type
stove. with no further preparation. Or, it can be burned in a box type stove by
cutting or breaking to length. However, there is considerable extra preparation
to reduce fuel size to the degree required for a TLUD.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Does this extra preparation effort act as an
obstacle to more widespread use of the TLUD Stove? Under what circumstances
would this extra preparation effort be justified?</FONT></DIV>

<DIV>from the point of view of chopping wood into small pieces, we found
bamboo to be an ideal type of wood. It is very easy to split bamboo vertically
into strips of 2 to 3 cm width, and once the bamboo has been split, one can
break the strips into pieces about 10 to 15 cm long, even with bare hands.

<DIV><BR>Any type of fuel need some kind of refinement or preparation,
dont forgt that.<BR>This goes for charcoal and fuel for the TLUD`s as
well.<BR>I would not say that cutting branches with a machete is "highly"
prepared fuel.</DIV></BLOCKQUOTE>

<DIV><FONT size=2 face=Arial># Certainly, it is a very simple task to chop
smaller wood with a machette. A simple "fuel chopper" can do this very
easily also. However, the labor for chopping is excessive, and creates
much extra work for the Cook or her/his helpers. With a "Whole Body
Machine", (eg, a treadmill or a "Walking Pump") an adult in good shape can
deliver a maximum of about 1/5 of a Horsepower on a sustained basis. (5
people equals a 1 HP engine) On the other hand, a machette, operated by
one arm, can perhaps deliver .01 to .05 HP (20 to 100 people on machettes
equals a 1 HP engine) Things become very different when waste products,
such as fruit pits, screened mill waste, etc are available. The labor
content is greatly reduced, and the only other step required is adequate
drying. The TLUD can thus be a superb tool for efficiently burning such a
fuel, that would otherwise be difficult to burn effectively. Rocket style
stoves need "stickwood", that can be burned directly with minimum
processing. Both stove systems are very good for "the right fuel", but are
very bad when fed the wrong
fuel.</FONT><BR><BR></DIV></BLOCKQUOTE></DIV></BLOCKQUOTE></DIV>
