Serious Charcoal Making DIY - make your own charcoal
I'll make a video of the woodgas stove I made. It makes great charcoal.
You can make these the size of bean cans and those work real good too.
It's more efficient, using less wood and makes a great cooking stove too.
It burns top down or Downdraft Gasification and there's no guess work
when your charcoal is done. The gas stops burns, your done.
Same way the old timers created charcoal in the video, but on a faster and smaller scale.
What's nice, but takes longer to burn is you can use green wood which
burns about twice as long.
It took me a very long time to get enough solid details to make one that worked without a fan.. When they work right, there isn't any smoke,
the smoke is in the burning gases.
You can be using charcoal for filtering drinking water also, not just growing
plants. If you have sand for planting.. save some, just in case.
