Backpacking stoves, Twig stoves, bush cooker or bush stove what ever you want to call them they have several advantages over a ground fire. The contain the wood and allow the heat to rise and not be wasted out the sides. They allow a fire to be brought under a tarp roof with reasonable safety. They seem to regulate and take full advantage of small amounts of wood. Some are just containers with air holes and some are gassifier stoves. That means they reburn some of the fumes put off by the fire. How this magically works? I cant explain but I know it works. In this video we allow 9 ounces of wood for a ground fire and 9 ounces for a Four Dog Stove Bush Cooker in a head to head test.
