Hi Wayne,
I should have wrote - Wood-Gas burning stove, so a bit of both!
The stove is probably the best wood burning stove I have ever come across, and I've tried a few. I've copied a bit of text from elsewhere to try and explain it in better words than I could -
The basic Bushbuddy design is very clever, you will see a series of holes around the base of the stove. Air is sucked in through these holes and drawn up between the walls of the stove and the inner chamber which heats during use. As the stove warms the air flow becomes hotter and this hot air is then expelled through a second set of holes which sit on the inside of the top section of the stove. Warm air is then blown across the top of the fire. This almost seems to turbo charge the fire, indeed, on several occasions – when using the stove in warm weather – I’ve heard a kind of turbo woosh as the air being sucked through the stove reaches its optimum temperature.The first photo shows the holes, internally and externally. Also, you only need about half the amount of wood shown to boil a kettle of fry sausages.
Photo 2 shows the stove in full flow, you may be able to just make out the lit gas in the two middle holes. Not the best shot to describe it, I must try next time I out to capture it properly.
And the last photo shows the end result

Note how much of the wood pile is still available.
