I've been thinking about cheap ways to store fuel for cooking and did a few searches for charcoal and it seems like a cheap and easy way to store fuel for emergency cooking a lot cheaper than propane. Of course the main thing is only cook outside and not inside. Has anyone ever done a test or read something online about using charcoal for emergency cooking fuel? Like whats the most effective way to burn the fuel, how many bricks does it take to boil 2 quarts of water for 10 minutes for example. Has anyone ever seen or know how to make a cooker of some sort that will work the best to get the most burn time out of the charcoal or will a simple small grill work fine. You could probably even use a charcoal chimney to cook with since it has holes in the bottom, easy to light with paper, and directs the heat straight up. When I get a chance I would like to do a test and see how it works. If it works well I wouldn't mind buying a few large bags and store them in 5 gallon buckets with the rubber seal to keep moisture out. I read a few things that said you could get a years worth of cooking charcoal for under $100.
