lets talk about a real survival stove,not a sit at home and wait for the power to come back on Coleman or a hide out in the woods pop can stove but one that would be in a kit that is only opened as a last resort..you have only the fuel that is packed with it and you have to use it because for what ever reason you can't start--note i did not say have,but start a fire.wet,snow,whatever.having this will mean the difference between getting on the pick-up craft/vehicle tired,hungry and standing and not carried on hypothermic and semi-conscious.
