This modular stove is built from used metal containers.

It has a center fire burner module, a sunken 8-liter pot module, and an insulated/ chip drying top cap.
The burner and is made from an institutional food can. It takes all the ware and stress from the fire protecting the rest of the stove body.They are easy to build and can act as fuel cartridges to store fuel for quick and easy use.
The burner module, under development, adds secondary combustion air to the top of the burner.
