I currently choose between an alcohol stove and a petrol stove depending on the trip, but I'm wondering about being able to burn wood for longer cooking. This would be to cook in a pan of about 12cm diameter, or a metal mug (quite possibly cook in one then boil in the other). This means an open fire, even if suitable for the location, would be awkward. A portable wood-burning stove, on the other hand, could replace the windshield of my simple alcohol stove to conserve liquid fuel.
I've used (but not built) large rocket stoves, and of course have made plenty of campfires, but all that's shown me is that burning wood slowly in small quantities needs care.
So what's a nice light, simple DIYable miniature woodburning stove?
