I'm digging this stove! Will definitely have to make/test one. Considering the weight of fuel saved, this appears to be a good tradeoff. It would give the youngster something to do while I set up camp - collect wood and get the fire going, something I would not let him do when cooking with volatile chemicals. Also could keep it going without "wasting" fuel, for additional cooking, roasting, etc.

Q: what size pot will it fit in? i.e. overall dimensions?
