<p style="margin-bottom: 0in;">Dear Jonathan</p>
<p style="margin-bottom: 0in;">I also like you find that burning
Jatropha directly in a cookstove will be a good idea. It was also
me
that first got that idea. Our Jiko Bomba cookstove are still a
very
good good stove for burning Jatropha seeds.</p>
<p style="margin-bottom: 0in;">However at present I do not advocate
for burning whole Jatropha seeds in a cookstove, this has there
reasons:</p>
<p style="margin-bottom: 0in;">Health risk.</p>
<p style="margin-bottom: 0in;">We know Jatropha oil is poisonous. I
have personally experienced getting headache when testing
cookstoves
burning Jatropha seeds. Other have told me that they have got the
same experiences.</p>
<p style="margin-bottom: 0in;">I have not been able to find
information on the health risk from gasses from incomplete
combustion
of evaporated Jatropha oil gases. That means we have no
information
on the health risk people will be exposed to by using cookstoves
burning Jatropha seeds.</p>
<p style="margin-bottom: 0in;">As long as we do not have such
information I do not personally find it right to promote such
stoves.</p>
<p style="margin-bottom: 0in;">I would very much like if studies on
these issue could be carried out, but I am not aware of such
studies
are going on.</p>
<p style="margin-bottom: 0in;">Outreach.</p>
<p style="margin-bottom: 0in;">Quantities of Jatropha seeds are
still
limited. There could maybe be some 100,000 ton of Jatropha seeds
in
Tanzania for colletion. Of these at least half will be bought up
by
companies for pressing Jatropha oil. That leaves in best case
scenario 50,000 ton of Jatropha seeds for burning in Jatropha
cookstoves, </p>
<p style="margin-bottom: 0in;">to cover for 50,000 households fuel
needs.</p>
<p style="margin-bottom: 0in;">On the other hand we know there are
between 15 million to 20 million ton of agricultural residues
produced annually in Tanzania. The livestock eat some of these and
other will go to waste. However this is still an energy source
that
utilized as pellets could produce energy for all Tanzanian
households
cooking need. So I find more perspective in the pellet option.</p>
<p style="margin-bottom: 0in;">Jatropha as a cash crop.</p>
<p style="margin-bottom: 0in;">I will still maintain that most
farmers
will not burn Jatropha seeds as they see them as a cash crop.

will here not make comments to what Jonathan writes about the
historic development of the Jiko Safi and Jiko Bomba, and
neither on
their performances. I will neither comment on our company Kiwia
&
Laustsen Limited's grant funding or our economy in pelleting. I
do not
find it appropriate to take such discussion in this forum.<br>
