John Suavecito wrote:The pictures on this post really help people see how they can make a system like this work. Nice job Trace. I knew I was going to make biochar, but it took me 3 years to find a system that would fit my property, getting the barrel, drilling the holes and finding the parts. I think that your pictures and description are going to help a lot of people figure out how to make biochar. I try to post frequently in this forum because it has made a huge difference in the quality and output of my garden, and I think a lot of people want to do something like this, but they need to see the practical steps that will get them from wanting to make it to actually making it as a regular practice.

After you are done with it, you put it up for free on Craigslist, or take it too scrapyard for recycling.

My T-shirt caught on fire while using one to make my biochar oven. Pretty wild to look down and see yourself on fire. No pain though. I got it out quickly. Totally worth it.
