[Stoves] Jatropha fruit as fuel?

[Otto Formo]

Dear stovers,
I would guess that "any" gasifier will burn jatropha seeds or pellets cleanly and efficient, as long as the moisture content are less than 10%.
We have in the pipeline to test a new design of natural draft gasifiers, using jatropha seeds and pellets, for emmissions and toxcic fumes.
We should be very carefull adviceing people using these types of fuel, before it has been carefully tested by independent institutions.
Have a nice weekend.
Otto (not the famous one..........:)

Dear Jonathan I am interested in the general layout and dimensions of a stove that will burn the seeds well. Are you sharing at this time anything regarding the design? Thanks
Crispin++++++++ Dear Joyce and stovers all,
 
My regrets for not responding to this request 6 months ago.  I admit that it got lost in my messy inbox which I have now reduced from 6000 messages to a mere 2400, and in the process uncovered Joyce's email.
 
Burning Jatropha seeds whole or in briquettes in open cooking arrangements is a bad idea.  It produces a smoky, smelly fire and probably exposes cooks to toxic emissions.  I even question burning Jatropha oil in lamps in enclosed areas for the same reason. Maybe others know of emissions studies.
