The Thermette would look hysterical carabinered to a backpack. It'd be like a section of copper stovepipe bobbing on your back.

Their serious utility is for long-term survival in remote places where wood and dung are all you can count on for fuel. Or worst-case urban survival scenarios in which propane and other modern fuels are scarce or unavailable.

They are a neat car camping curio. Not practical for cooking a meal for a family. My main interest with it is hot water for coffee or tea.

Every survivalist should have at least one.
