Of all of the types of fire starting equipment, what would you choose to put in a waterproof box to go in a BOB, 72 hour pack, etc. for a no-fail, no BS fire starting kit? I'm also going to pack a 15 min road flare wrapped in plastic.
I learned that the hard way while driving down the highway one time, lol.When I was on the road in my rock band days decades ago I carried an extra 9v battery or two in my pocket for effects pedals. I found that if I dropped a few coins in with the batteries it would quickly get uncomfortable. So I guess "very short term" could be a battery and some metal, preferably wire.
I've got a woodstove in the basement that won't draw when the temp is below 20 or so. I heat it up with a can of denatured alcohol like that. Works great.Forgot to mention that one of the quickest no BS ways to light a fire is to cut an aluminum can in half fill it with gas, light it, and pile your wood over it. A good sledding buddy showed me that trick. Burns a long time in the can like that.
I always use a good base of wood, that my fire is built on.
