you can make coal/charcoal if you have a resealable drum, metal pipe, and some wood. you just gotta put a hole big enough to put the pipe through it, put the pipe so that it is in halfway in the barrel, put wood in their, start her up and wait about 24 hours or until it burns out, bust up the bigger chunks of wood with a sledgehammer, and you got some passable coal/charcoal.
