The Backcountry Boiler is a camp stove of sorts that combines the functionality of a cooking pot and a stove into one. It eliminates the dependency on gas or other liquid fuel to heat water in the outback.
It is called the swedish fire log. pour and soak for a few days or weeks. then when you need it start it on fire and you have a fire log that last for hours. we did this in the snow when we had parties or people over to keep warm.
