There are three major innovations that make this stove different and more effective than any other cook stove that has ever been invented:
Adjustable Air Flow
The vented chimney base allows for adjustments in airflow through the constricted Heat Distribution Chamber by simply rotating the chimney. This allows for user control over the regulation of airflow, resulting in maximum efficiency.
Monolithic Concrete Construction
Monolithic, precast construction allows for efficient mass production in third world countries. Concrete construction and clay insulation eliminates radiant heat loss.
Reconfigured Heat Distribution Chamber
The Heat Distribution Chamber is paramount to the increased efficiency of the Gospel Stove. The constricted chamber allows for more even delivery of heat to the cooking surface. This creates added efficiency by increasing the amount of food that can be prepared at once.
