Inspired by the Asian idea that the earth was square and heaven was round, the Double Warm Multi-functional and Energy-efficient Coal Stove was conceptualized. It is designed to have a water-storage volume surrounding the furnace so that you can boil water while you use the stove for cooking. This hot water can be used for bathing etc. Nice idea, especially since it is aimed for the energy-starved counties where resources are expensive and scarce.
