I've devised a simple method of converting a stump to a rocket stove.

Using a chainsaw with a long bar, plunge the nose strait down. Then dig a hole beneath soil depth at whatever spot is easiest, lowest on a slope or toward the prevailing wind. Do a few plunge cuts horizontally to meet with the chimney. A fire in the lower cut will naturally find its way to the chimney. The stump could be allowed to burn out or fires could be snuffed after each use if a stove is valued more than the removal of the stump. Wood is a good insulator so a stove like this will work well once the first fire dries out the core.

Anyone who has burned out a hollow stump can attest to the huge increase in burn rate once the fire perforates the side of the stump, thus allowing air flow. This is natures rocket stove.

I believe this is the fastest way yet to create a rocket stove for outdoor cooking. Two flat rocks may be needed, one for a feed door damper and one as a snuffer and rain cap. Cook flatbread on a chunk of slate.

Not advisable during fire season.

Not advisable if you are on peat, muskeg or other flamible soil.

Don't try this in the livingroom !!!

Photo to follow. I need to find a suitable stump.

Notice the difference in the "rockety-ness" of the taller log in the german video. Having done this with many a chimney logs, I can attest to the direct relation between the height of the heat riser and it's increase in temperature and stronger combustion. Oh, and they are quite fun and efficient to cook over while camping.

Well, that seems to prove the theory pretty well. I need to search YouTube whenever an idea arises.

I would guess that with a green stump, there would be occasional steam explosions. After the chimney burns to an ideal size, it might be possible to line it with fire clay in order to prevent it from burning out. I suppose I should YouTube that idea before carrying it any further.

I doubt that I will ever run out of stumps, but in some cases you may want to preserve it for future use.

That's Amazing Dale I was just thinking I needed a way to remove stumps with minimum fire. So I though RMH tech, search permies and here it is! Thank you Satamax for the links!

My thoughts exactly . Bumping this since a new thread is trying to figure out the same thing.

Here's a great example posted today. Very rockety.

I've been plucking my stumps with my tenant's excavator and using them for hugelkultur. I still need to try this. Most of my time at the farm is during summer fire ban season.

 
Ever since I found this suit I've felt strange new needs. And a tiny ad:
