I just ordered one, thank you. My intuition said this was an excellent idea. I'm thinking more along the lines of a solar flare where the grid goes down for some amount of time. Could heat a can of soup/beans/meat/veggies/coffee out of a handful of twigs. Very economical, a fire would require ALOT more wood. Plus like the person said above, you could charge your ipad with all your survival stuff on it.
