Problems with traditional cooking stove viz. fire wood consumption, cooking time, etc. http://gyti.techpedia.in/files/GYTI-BOOK-color.pdf
The improvement in the traditional cook stove was achieved by fabricating a simple twisted tape assembly (costing about Rs. 65), which could be placed on it. This was done without making any changes to the cook stove. The field-level tests resulted in reduction of firewood consumption by about 21%, soot accumulation by about 38% and the time of cooking by about 18.5%. People’s participation was ensured at all stages of the process, from initial planning (studying available options, cooking practices, capturing needs) to the actual use in the field. The performance of the cook stoves was evaluated by modifying a standard Water Boiling Test to accommodate the existing cooking practices. The challenge was to devise region-specific testing methodology that would take into account context-specific realities. The optimization of the twisted tape device was first carried out in the laboratory and then implemented in the field. Overall, this participatory process not only addressed people’s perceived needs but also ensured no change in their existing cooking practice, while providing a simple affordable locally available solution, acceptable to all.
