From Smoky Kitchens to a Statewide Stage: How Teen Innovator Shambhavi Sharma is Lighting Up Bihar’s Clean-Cooking Dream

Patna, September 12, 2025 – When Shambhavi Sharma thinks back to her childhood visits to rural Bihar, she remembers more than the warm kitchens and simmering pots.

“My eyes would burn, and I’d cough for hours,” the 17-year-old recalls. “I kept wondering why cooking, a daily act of love, had to hurt.”

That memory has now become her mission. On Thursday evening at Patna’s Bapu Tower, the Class 12 student from Delhi’s Sanskriti School walked onto the stage of the Bihar Idea Festival 2025 to a standing ovation. Union Commerce and Industry Minister Piyush Goyal placed a shawl around her shoulders, honouring her invention: the “Low Smoke Chulha,” a clay-and-brick stove that slashes indoor smoke by more than 60 percent while saving 20 percent of firewood.

The stove, nicknamed Vayu Jyoti, or “breath of light” looks deceptively simple. Two air inlets, a bypass mixing chamber and a soot-filtration zone boost airflow by 30 percent and cut over one tonne of CO₂ every year. Built entirely from local materials, it costs just ₹300–350, making it accessible to the very families who need it most.

“Clean cooking should not be a luxury,” Shambhavi told the packed hall, her voice steady despite the flashbulbs. “My dream is to see technology like this in every rural household, improving health and well-being.”

Her idea dovetails neatly with Bihar Chief Minister Nitish Kumar’s Jeevika Didi Mission, which empowers rural women to adopt sustainable cooking methods. It also resonates with a broader movement: thousands of Jeevika Didis, start-up founders, and student inventors thronged the festival, turning the state capital into a buzzing lab of grassroots innovation.

Bihar Industries and IT Minister Nitish Mishra called the young winners proof that “our biggest challenges can become our greatest opportunities.” The event drew senior bureaucrats, IIT Patna researchers and policy leaders, all eager to glimpse the next big idea to emerge from the state.

For Shambhavi, the honour is both personal and practical. She plans to make the design open-source and reach 10,000 homes, ensuring anyone can replicate the stove. “If every village adopts it,” she said, “we can clear the air, literally, for the next generation.”

From a smoky kitchen in her memories to the bright lights of a statewide festival, Shambhavi Sharma’s journey is a reminder that innovation doesn’t always start in a lab. Sometimes it begins with a cough, a question, and the quiet determination of a teenager who refuses to look away.
