Natural draft woodgas stove and biochar trial findings

Do you plan on commercializing your stoves? I am in canada and am very interested in doing garden trials w/ biochar. I will be building an off-grid home, so a set-up like this, where the gases could be vented outside, would be perfect. Do you get a better yield of biochar with this stove compared to your other fan driven model? Have you a working wind-up fan set-up? As WoodchuckininPA asked, could you advise on the construction of one of these stoves?

Moring Rob Ssure doesn't take much fuel that's for sure! A normal stove that't not carbon negative would have exhausted the supply long before an hour. Excellent findings.
My next challenge with the Joe Pipe is to design a swirl gasifier for cordwood. Joshua.

Very impressive!

Are there plans available for building a stove like this?

Thanks!

Bamboo is such a great resource. I am very impressed with your work. Did you make your stove or did you purchase it? I am working on my lawn with some products for soil fertility. It's made out of ground fish and sea kelp, it seems to be slowly working but I would have liked to get deeper in the soil and used biochar. If you can raise soil fertility using low cost local material it wood be a big help to many people. The price of fertilizer is getting very prohibitive.

Does the size of the charcoal particles matter? I was going to crush my charcoal into small pieces to see if it worked better. Also would soaking the charcoal in liquid fertilizer help?

Very interesting, nice clip by the way. Have you done any test on corn or soybeans?

Well on this trial I modified the subsoil with beneficial fungi, but I've recently seen some very promising trials that produced a similar effect when the biochar was mixed with non biological compounds!
