No power? This brick rocket stove is easy to make and it will work great for cooking

During an emergency,

the ability to purify water and cook food could be critical. This improved brick rocket stove could be built for about $10, if you have to buy the materials. It’s possible to salvage all of them. This is an improved design from the previous SurvivalCommonSense rocket stove post that has received more than two million views. You use any biomass stove at your own risk, since a variety of unforeseen circumstances and/or materials could affect the safety of the stove.
