Notes from Paul Anderson
Gustavo has presented a very nice video of the use of a tall TLUD gasifier under a DUAL purpose stove frame (frame = stove structure without the heat source) that first boiled 5 liters of water in 12 minutes, and then converted into a plancha stove with chimney, cooking papusas (related to tortillas). Total cooking time 1 hour 45 minutes on one batch of wood chips/chunks (5237 grams) that yielded 1300 g of char. 25% weight yield of char. Probably could have operated an additional 10 minutes with pyrolysis fire and a slightly lower percentage yield of char.

Note: That is approximately 4000 g of fuel of pyrolytic gases (including moisture content that was probably near 15%). Any ash content (probably 1% of the raw fuel) remained in the char.

Urban Justa Stove Building Workshop in San Francisco

Sebastian Africano was just through the SF Bay area, building stoves on his way to Stove Camp, and I added this post on his workshop to my evolving IAP site:
