Hey Man, Thank you for this simple video, Super cool and simple way of making Bio char. Love it

Absolutely brilliant fellers great use of materials well done 👏

Sympa

Great video, Tom. I'm going to try this method.

Seems like you've been making biochar for over a decade now. At half an acre per gram of biochar, how much can a person possibly need? Are you selling it?

where a breeze brings oxygen to the fire is where ash will form--you'll see the white ash beginning to form on the black burning wood--that's where you need to add wood to burn above the ash to eliminate the oxygen supply abd prevent the ash from forming.

Great job... All I need is the 30gal barrel.. The hunt begins today!!!

I use apple crusher to crush biochar. Works well.

@Whoop!!

Awesome video. One question though, what happens if one replaces the woods inside the smaller barrel with circuit boards? Does this system turn that into charcoal without smoke? This can solve a lot of ewaste problems.

Greetings...Long time between drinks (last video). I like the Many Health/Growing Benefits that is produced from Charcoal. Thanks and Cheers from Australia.

Excellent presentation, thanks!!

Dude. That's a great idea. Thanks for sharing. Saves building a barrel setup.

good video, thanks. I put my char through a mulcher/chipper - it must be moist though to prevent a lot of dust. Can be put through a second or third time to get it smaller - much easier than trying to pound it up manually, cheers

excellent presentation/excellent explanations too. Good job. I;ll follow all your directions!! thank you!

I think you're loosing heat through upper diamond shape holes. You might get better results without them.

Okay, I've researched a lot of retort kilns and barrels. I don't see what makes this DOUBLE retort. Explain it to me please.

Thank you very much, great efforts.

I been using a similar method, I also been getting good results and a clean burn. I get good quality biochar and charcoal.

Best video on the subject I've seen. I hope you start making videos again. Are you in CA or OR?

Ahmed, you are confusing this with a double retort. see my other video for the clean-burning double retort. kzfaq.info/get/bejne/ft91ddWTytzMYps.html

you need to add an inner chamber and drill holes in the surface of the inner chamber , coz the air needs to comes from the sides as well , the air heats up and mixes with the wood gas and ignites ;)

yeah, Anders, it took a while to get the sizes of the holes and stove pipe right. now finally smokeless. remember, for your idea of making char in the outer ring, it will need to be airtight, with a few holes at the bottom inside for gas escapement. sounds intriguing, but also a lot of work, unless you are a great metal worker with extra time. glad you are making char. have you been making it in a wood stove also? see the other video: Mini double retort: mini double retort merry christmas! t

Hi Tom, thanks for the great video. This double barrel retort is also the retort I have had the best results with. One thing I havent tried yet, but can see that you are almost ready to try, is to put materiel in the outer protection ring. Merry chrismas. Kind regards Anders Jensen Denmark (Europe)
