Crispin, Thanks for your interest in the jiko safi Jatropha seed micro gasification stove. We have developed templates and fixtures for use by metal workers in countries where we promote the stove, as is clear in the stove construction video, but we have not put together dimensional design drawings of the stove. The general layout and approximate dimensions should be obvious from the two video clips at the website jetcitystoveworks.com. One deviation from classic ND-TLUD design is a central air cylinder, which we found necessary in order to completely combust the long hydrocarbon chains of the gases in Jatropha seeds. For a view of this piece under construction is seen about 6:40 into the stove construction video. We also use an integral enclosed stove top and chimney for reasons you will understand. Obviously, one-off construction of stoves is the slowest and most expensive way to do this. I'm surprised how precise the metal workers can be with these limited resources -- all 40 stoves made to date function very well. Our next investment will be to equip this artisan's with some shop tools. Still, one advantage of this tedious method of construction is to demonstrate for any viewer the various parts of the stove and its fabrication. Jonathan

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.
