This works great, a very solid dry log is a plus!
Cut the log evenly on both sides so it stands up freely. Then cut it into vertical segments most of the way down the length of the log. Stuff in some newspaper into the cracks as deep as you can get it, leaving a wick at the bottom, and light it up.
That's all there is to it—the log burns from the inside out, and you have a simple, handmade stove.
