Primitive Technology demonstrated how to build a forge blower using sticks, clay, fire, and other primitive methods. A forge blower forces air into a fire to increase its temperature for things like smelting ore.
I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project.
