The trangia uses one little can of fuel, alcohol, per day if I cook breakfast and dinner. I almost always have a cup of hot cocoa for breakfast, but sometimes I don't eat a regular dinner. Just a protein bar. But I have never weighed or measured the fuel and bottle. The trangia fuel bottle is plastic. I need to weigh it too. My guess is that overall this is about the lightest I can go with cooking, unless I do I twig stove, which I have never done before. My biggest fear, as posted here in the fear thread, is hypothermia. So I worry about depending on getting a fire going in the event of an emergency, to get some hot drink into me.
