The Spruce Stove embodies a new approach to burning wood. A complete tree trunk can be consumed by this compact stove. The aperture is a diaphragm and encloses seamlessly around the tree. By gently pushing the trunk inwards during the burning process the experience lasts as long as the trunk. A stove is one of this everyday tools that seems to be as old as mankind, therefore it’s particularly interesting to see that even here innovations in design and functionality are still possible.
