Natural draft woodgas stove and biochar trial findings

[bacien24]

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!

@WoodchuckinPA I saw a fairly long video on a Chinese video site of someone taking apart one of these stoves and then reassembling it. If you are still interested, let me know and I can try to find the URL.

@rachelmaaa

Yes, please!

Thanks!!!!

@WoodchuckinPA Found it. But YouTube does not allow me to post the URL. You can google for "50064 高效气化节柴炉" The Chinese translates to "high efficiency gasification burning wood stove". The video is 17 minutes long and provides disassembly, assembly, cost breakdown, and usage. According to the narration the video was made to seek investors for its production.

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?

Hi Buttkracken,

I always try and crush the charcoal in to small pieces 1-2mm as I feel it gets distributed better in the soil. If possible do some pot trials (Min 3pots per trial) using some soaked and unsoaked with char of different size and see how you get on.

Regards,

Rob.

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

[Agrisonic]

Yep!

Got some really good new photos from my latest trial using modified biochar in low application, send me an email and I'll forward you the pics.

Regards,

Rob.

Rob,Did you get my email address?

[Agrisonic]

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!

Nice job! What do you mean by "modified" biochar? I understand the basics of biochar and have made my own, but what about it is modified?
