2-Barrel Nested Retort
Folke Gunther, Sweden
We are grateful to Folke Gunther in Sweden, who devised this most simple, elegant, easy equipment to safely make reliable batches of backyard biochar.
Folke's simple 2-barrel retort allows newcomers to experience the thrill and wonder of gasification.
We encourage people to begin to imagine what else can be done with that gas besides burn it off right away.
