Kon Tiki Biochar Kiln Introduction

This video features an Open Deep Cone Kiln which was developed at the Ithaka Institute. One of the main differences with this biochar method to most biochar stoves, is you get to see the fire. This aspect alone makes the process much more enjoyable.
For more information about the science and application of biochar and how it can improve the health of your soil, your produce and therefore, you, please visit our website at www.thebiocharrevolution.com/

I think this is the most pragmatical way of doing Biochar, or turning season "wast" materials in something very valuable on a farm, small poluttion, easy to understand. Other methods are better or more adaptable to reuse the heat, and off course more sustainable for the industry. This is a no Brainer, perfect to every village. Congrats on the project!

Good resource, I'll add it to my playlist

[@Folke46]

The richest Terra preta soils contain about 90 kg/m2, but the amount depends actually of how much you can make

[@roberthayes2027]

@@Folke46 I wonder how much per cubic meter? I mean even in an archeological sense with terra preta. Also, is there an ideal target for a percentage, like in France there's 4 per 1000, etc. considering the climate remedy. It can seem confusing when talking about how to measure the amount which might be ideal and effective for agriculture. Do you agree? Wondering where research is leading us about proportion and productivity. Is there a good link for summary and useful abstract?

[@luisferreruela52]

Very interesting, what is the thickness of the cone's walls

[@willjames5243]

What does the grate do?

[@turbonbc]

How much of this stuff you use per cubit foot of soil?

[@hurricanemuscle]

Can ricehulls be charred in this cone kiln without smoke as in carbonizers?

[@Parasuniversal]

I didnt realise that the water will come out clean. What happens to the ash?

[@alessandrowedeman1925]

I love it but I had a question about the water, wouldn't it be high in Lye, given that the water soaked in ash?

[@robertlehmert1336]

When the narrator says "it feels a little soapy", he's talking about an elevated pH. Could be 11 or 12. I usually add a good pour of vinegar to the quench water and let it soak for a while. If you are using it in soil, I would suggest mixing compost into the char and letting it adsorb into the char before applying it to soils.

[@user-cn4fy4mc9n]

how about optimal angle ?

[@RawFoodMuscle]

Does anyone sell this kiln or is it something that has to be built?

[@linsonantony4335]

BadAssFarmer I can make this kiln as per your requirement. Please let me know

[@timtation5837]

Congratulations!!! You made a giant Webber BBQ grill... Next time throw a grate on it and cook something... Sheesh!

[@MichaelFingland]

Where can I buy one?

[@frankie6655]

does biochar not need to undergo pyrolysis where it is heated in the absence of oxygen?

[@highplains7777]

It IS being heated in the absence of oxygen underneath the top layer. There is some loss to ash/full combustion.

[@zuzu7587]

Note 1.15 min : The cone 63.5 degree side.

[@phillipbertrand8514]

how small can wood be. wood chips. brush and how dry

[@robertlehmert1336]

Wood chips can be problematic because of compaction. I'd build a support structure with other brush and add chips slowly so they are able to be properly pyrolyzed. Whatever you put in should be as dry as possible.

[@sempribid6924]

Is it good quality too for making bbq charcoal?

[@QuiChiYang2]

The ancient pre-Columbian Olmac, Inca, & Aztec civilizations were a stone age society. No metal. They were advanced in mathematics and engineering. They were outstanding masters of agriculture. Terra Preta (biochar, no oxygen) was produced in the Amazonian rainforest with wood, weeds, clay, mud mounds. If there was a death they were placed in the fire mound as well in burial jars. The charcoal, pottery chards, were then used for gardening, waste management, water treatment & cattle & chicken management. Pre-Columbian Indians harmonized with nature. Abundance vs Greed based paradigm.

[@BurtWhitten]

could you barbecue a buffalo or goat next time

[@SergiyKlunnik]

Цікаво і корисно. Good

[@beunite-teambuilding-thailand]

I think the cone shape kiln is great, but what does not come across is that on the bottom of it supposed to be biomass (not wood), and on top is the fire. What you do is producing charcoal.

[@roguebiodynamics987]

Too many issues with this method. Open kiln of any type just won't allow control. Seems like tlud closed systems would be far better.

[@panstriato2]

Research done with this kiln says it makes very good biochar. https ://www .ncbi.nlm.nih.gov/pubmed/27191397

[@scottcroft86]

Control of what?

[@TheToygangster]

tested this method many times. you could argue that a closed kiln provides you available utilization of the heat and perhaps provides more cracking and porosity? The kontiki kiln provides more mass of biochar though.

[@selectedsolutions]

I think this is inefficient_as it produce more_ash

[@douglaspohl1827]

Learn what biochar is... without inoculation all you have is sterile charcoal at best... otherwise ash. Oops... the details are in the chemistry... prove me wrong... ask a qualified lab technician to perform chemical analysis... good luck!

[@punkrockcompound]

Sure. However this is an important ingredient in the creation of regenerative soil. Can be used for other uses too. I was looking for the best way to create biochar (for use in terra preta) and grateful for this video. ❤
