An essential thing to have, but, most people don’t even know what a rocket-stove is.
This is one of the simplest and oldest technologies. In this case, it’s mostly perlite (naturally material made from Volcanic Glass) combined with cement.
They’re designed to place sticks, twigs, logs, and anything else you can and wish to fit in a 3″ diameter mouth, for burning to ashes. The combustion chamber is enclosed and insulated, channeling virtually all heat created. Heat updrafts up and cooks whatever you have above, in a safe, efficient, and unique manor.
This mini rocket-stove only weight about 11 pounds. It’s uplifting and memorable to cook with this!
