You might consider ditching the trioxane in favor of a less toxic alternative-either a candle-based or a methanol-fueled system. The ultralight folks have developed pot-stove-windscreen combinations that weigh essentially nothing. Switch the edibles to that historic survival staple, nature's perfect food: Vienna sausages. Durable, good hot or cold, and they have enough nitrates on board that you can dry them out and make gunpowder of them. They are made out of parts of the pigs, cows and chickens that would be wasted otherwise, so eating them is an environmentally positive act. The cans make a neat little methanol stove-you can crimp the lip and achieve a snap-in fit on the bottom of a 24 oz heineken can to create a poor man's jetboil.
