>>2606536A simple oil "stove", made of a single aluminium soda can. Just put the oil inside the bottom part of the can and flip the top part of the can upside down after cutting it. Then, put a fuse (piece of cordage made of cotton or some veg fiber). You can have multiple holes on the top part of the can and multiple fuses. You can add cubes of solid animal fat oil that will melt with the heat of the flames and slowly leak into the bottom part, refilling the stove. It's basically an oil lamp, but can be used for cooking food. You can heat up a ceramic pot on top of it to use it as a heater.
You can use other types of materials to hold the oil, like wood instead of aluminium. This type of dyi stove can be used with alcohol too. Looks somewhat like pic related, but made with recycled aluminium cans which can be found in the trash everywhere. Oil is cheap. Soya oil, corn oil, canola oil, animal fat and many others are good choices. Oil burns for days and the cotton fuse lasts for a long time. Can use pieces of cotton shirt or shoelaces, or simply a cordage made of dry grass. High capilarity materials. Finer oils are better, such as olive oil (romans used it). The best is whale oil, which was used by nords, vikings and siberian natives for ages, when it was hard to get wood. Seal fat was also used. Always have oil, as it is good fuel for lamps, stoves and torches. When in the wilderness, don't be without oil, so it says in the bible. No oil means death, basically. Always save the fat of meats.
