Canoedogs, in your photo it looks like there's some chunks of dead birch trees. Slit the bark and peel it off the rotting wood and light it with your Bic. Burns like it's soaked in oil.

For me, a "survival stove" is a nice campfire. Granted, there are times where a stove is nice to have. In the snow, for instance.

For your life jacket, I suggest a girl-scout approved "buddy burner". Traditionally you take an empty tuna can and cut a strip of corrigated cardboard which you coil up tightly inside it. Melt some wax and fill the can. You could make it in something like a round mint tin with a lid for a pocket version.

It's shelf stable, as long as it doesn't get too hot or if you add the right amount stearin to the wax.
Waterproof.
Lights pretty easily.
Burns hot and long, even in the wind once it gets going.
Ruins your cookware with sticky soot, but who cares when you're in trouble?
Could also be used as a fire starter...
