1. Stove fuel: Maybe you have an alcohol-burning camp stove, or your made one like the beer can stove in our survival by beer gallery (link). For that type of stove, you'll need some very high-proof liquor (like Everclear, if you can legally get it where you live) to efficiently cook your food and boil your water. It burns slower and cooler than most other stove fuels, but it's not a permanent mess if it spills in your backpack or vehicle. Alcohol evaporates very quickly. If it's only going in the stove, you can buy denatured alcohol at the hardware store. This blend of alcohol is cheaper, legal, readily available, and it burns very well.
