>>2623168Get a aluminum soda can. Cut it in half. The top part is smaller in diameter. Cut it so it fits inside the bottom part while upside down. Leave some longer strips of aluminum so you can fold them around the edge of the bottom part of the can. Cut the bottom part of the can so it's about one or two inches in height.
How does this stove/lamp work? Just put oil inside the bottom part and then put the top part on top. Now get yourself some cordage, made of cotton or plant fibers. This is your wick. You can have as many wicks as you need, but the oil will burn faster. Simply put your wick inside the openings on the top part of the can, leaving a 1.5cm piece on top of the oil surface, and wait until the oil is sucked into the cordage. Now put a flame on top of the wick until the oil reaches flash point and ignites. The oil inside a soda can with a 1/2 inch height can last about 48 hours with a single wick, depending on how thick the cordage is. You can increase the height and brightness of the flames by using thicker cordage. You can increase the cooking speed by using multiple wicks to produce multiple flames. Aluminum is good because it doesn't rust.
You can use seed oils like onions, corn and others, as well as fish oil and animal fat. Whale oil was used for centuries in the past. Romans used olive oil. Pic related is a oil lamp or stove of similar design, but you can simply recycle aluminum cans like this or melt them to make your own aluminium parts. You can also simply use a piece of carved wood with holes as the top part. It floats on the oil and the cordage stays up. Can simply put some flat river rocks or wood as support for your frying pan, with the oil stove in the middle. Can also grind a flat rock until it is concave and can hold the oil. Can also use carved wood and a piece of leather to be the bottom part. Can use strips of cotton shirt to make the wicks.
You don't need to buy cheap shit that you can make in 15 minutes using some scraps and a knife.
