Thanks for clarifying this. This is exactly how I did the J-nut
burn. I did not open the "capsules" -- they were burned together
with the seed, so there was hopefully very little exposure to the
toxic oils inside. (They would likely have been volatalized within
the shell in the heat and made their was through the shell to be
burned as vapour/gas in the flame.)<br>

(This is a photo of the Jatropha nuts (J-nuts) both before and after
running through my TLUD stove. After carbonizing, you can see that
the seedpods shrink somewhat, but are essentially intact. ~ note: I
was a little concerned at first that if I did not crack open the
seedpods that they might 'pop' like popcorn... That didn't happen,
luckily. ;-)<br>

<pre wrap="">To stovers interested in burning Jatropha seed:
In nature, Jatropha seed is enclosed inside a capsule. If one is not
interested in extracting oil from the seed, one need not separate the
seed from the capsules. The capsules are dry and woody. They may be
burned along with the seed. Burning the capsules together with the
seed would save the labour of separating the seed from the capsules
and would also give more fuel per plant.

<pre wrap="">Lloyd,
I’m glad to hear you were successful in burning jatropha seed. We have the
same experience with it being smoky at the end of the burn which is why
we’ve been toying with being able to shut off the primary air toward the
end.
