Here's an article I found in "Backwoods" mag. I tried with fire like a caveman. I used the barrel idea for storage, but ran the line from the digester to containment barrel right up and under the water. I didn't put a "T" in i just ran i copper tube off, hence a toy Blowtorch. I plan to use one of those large construction water containment tanks to make a continuous digester in the future.
