The Survival Stove allows you to burn any solid fuel anywhere and anytime. This little firebox leaves very low trace residue and creates no garbage. All you need to create a high cooking heat (up to 20,000 of BTU – 1,200°F) is a few AA batteries. The Survival Stove will burn any dry fuel material such as wood blocks/chips, natural fibers, dry animal dung, cardboard, charcoal, etc. An ingenious internal fan creates a forge-like environment in the base of the stove, rapidly producing an intense heat. The fan will run nearly 24 hours on the AA batteries. The Survival Stove can also be used in very cold weather. $89.95.
