Primitive Technology: Forge Blower
Primitive Technology
A Primitive Technology episode in which the creator builds a bow-drill-driven bark fan to blow air into a fire, using only natural materials. It shows the progression from fanning a fire by hand to a rotary forge blower.
HN readers like the channel for showing technology rebuilt from raw materials, and cite it as a vivid example of knowledge building on knowledge.
