Ok. I saw this on another channel's video so I opted to build a better one that did not require strange steel cans of various sizes and complex procedures to JB weld etc etc etc. This design is low cost, durable, effective and can be scavenged in the wastelands. Paint cans? check. Screws? Check. This can also be made with a manual juice can opener instead of a drill and uni-bit. Every part can be easily had anywhere in the urban US and even further out. They are extremely efficient and use probably a tenth of the wood a normal hobo stove will go through per meal. This thing cuts your wood consumption down bigtime and still provides an ample cooking flame that is both smoke free AND low profile. With a tin foil windscreen around it...this thing is all but stealth. I have cooked substance meals off my little trusty hobo stove but this thing is something else. I could prepare a whole big meal using a quarter of the wood off that and remain warm off sticks and twigs and biomass like leaves, dry grasses or just about any combustible plant material. A single wooden pallet and a hatchet could keep me warm for the better part of a week and cook my food / sterilize my water. Peanut shells? No problem. Cow dung? No problem. Smoke? none. Smell? Minimal. Visibility? Negligible. A true prepper tool if ever I did build one.
