rocket stove [made from a log]

[T-oddity]

Your right TH it is a lot of faf when a straight forward fire will do, I've done a couple of these and boring the centre hole along the grain into the log can be a bit of a pain, definitly need a decent electric drill and a good sharp bit. Lighting them too can be a bit slow going, plenty of birch bark or fat wood sticks are a good idea.

The real advantage with them is they work very well in wet and windy conditions, ideal for under a temporary shelter, they burn for a considerable amount of time, you don't need any other fuel and do make a very good stove.

Wouldn't look too conspicuous left amoungst other logs and sticks at a bol.

Handy to have in the back of the shed at home as an emergency stove to cook on if all else fails
