Sarfuddin Kazi, a machinist from Jalgaon, Maharashtra, developed a kerogas stove in the early 1990s after observing the limitations of conventional kerosene stoves. The 45-year-old runs a welding workshop where he fabricated the stove’s components himself, drawing on practical experience rather than formal technical training.
Kazi’s formal education ended after he failed Class 6, and he describes himself as barely literate. His three brothers also work in the workshop, with none of them having undergone formal technical training.
