Wood stove, part 2

Well, I ran my test this past weekend at the Cyprus Lake national park.  It worked extremely well.  I thought the outer can would be warm or cool to the touch.  Man, was I wrong!  It was super hot!  Once lit up, I could clearly see jet flames coming out of the upper holes in the inner can.  The whole thing worked so well that all the wood I placed inside the wood burned into ash within 10 minutes.  I think that would be long enough to boil maybe a litre of water.

Now, a small alteration to the inner can ... I have just made a bunch of holes at the top of the inner can.  This way, I can place a pot directly on top of the inner can and air can still escape from the inner can.

The aluminum hollow disc at the bottom of the picture below is used to cover the space between the inner and outer cans.
