Update, the stove boils 12oz of cold tap water in about 10 mintues. That's about 2/3rds full on the cut down Heiny cook pot W/O a lid. Then contines to simmer for another 5-10 minutes depending type of wood used and the size of load being burned. Burner can volume size is only about 10oz so that's not much in the way of wood fuel maybe just a small handful! Pencil size 1-2" twigs shaken down to pack tightly then a top layer of pine needles or dry brush/leaves to quick-start the burn. A few drops of alcohol gets the show going. With a windscreen, back-up tea candle alcohol stove, lighter, storm proof matches, 2oz alcohol fuel bottle and coffee singles it's a little over 9oz. Not bad for a multi-fuel complete cook kit? It could last you for a 4-5 day BP trip or longer depending on conditions for finding dry fuel. BTW I only boil water for freezer-bag meals and also drink tea or morning joe from the same pot to keep it simple. I've found the cook kit fits nicely into an old discarded shirt sleeve to keep from rubbing pine tar on my other gear.
