Design and Implementation of Concrete Thermal Storage Stove

Cooking has been an important part of mankind civilization. Several means of providing controlled heat for cooking had been developed in the past. However, as civilization grows, the use of refine fossil fuel and electric stoves became the dominant means of providing heat for cooking. The cost of refine fossil fuel had regularly fluctuated and generally increases on average. In some locations in the world, the time for supply of electricity and the duration of it availability is unpredictable. Also, the cost of electricity varies between the day and the night in some countries. These problems led to the development of a thermal storage stove. The stove use electric heating elements for direct cooking and charging the thermal energy storage unit. The stored heat energy will be use at any time of the day. The stove with a theoretically estimated heat energy storage capacity of 2.7 MJ was constructed. And from measurements, the device was found to be more effective in the first 10 hours when charged to a device dependent temperature factor of about 82 0C.
