That's the first time for me. Thanks for showing another well made stove design. He sure does come up with some unique designs. He must eat, think and sleep stoves. He probably spends an hour or two a day browsing through the local stores looking at containers on the shelves that he can make into a stove :D

Now if he can only utilize the radio active waste from their tsunami damaged reactors. :idea:

I have no idea if it would work or not, but I'd love to see this design coupled with the mesh/fiberglass of the starlyte. I really like the idea of once I pour in my fuel if it gets knocked over, fuel doesn't go everywhere. Again, NO idea if it would even work.

I viewed the video again and found a mistake in his drawing. I left a comment for him:
Your drawing at 3:00 is incorrect. Capillary action takes place on the high place where the metal of the inner wall touches the outer wall not in the crevasse as indicated by the blue lines.
In one of his other videos he made a mistake also about the capillary action. :o

I might be wrong but I honestly don't think this stove is an example of capillary action.

Capillary action happens without (and even against) outside impetus or force. In the case of this design, it appears nothing is being drawn up until you turn on the heat.

I think it is more likely an example of thermal transpiration, in which case a temperature gradient is drawing the fuel vapor up along the narrow "crevasses", similar to the action of a Knudsen pump.

Just a guess.

Yes you are right. The drawing is deformed because I have no aptitude for painting. Only vaporized fuel goes through blue line. Thanks pointing it out.
