NIT Warangal develops induction stove that can heat all cooking vessels

Hyderabad: Researchers at National Institute of Technology Warangal have developed a new induction stove that can heat all types of cooking vessels — including aluminium and copper — marking a major step forward in everyday kitchen technology.The innovation, led by professor N Vishwanathan and professor S Porpandiselvi, addresses a long-standing limitation of conventional induction stoves, which typically work only with iron-based cookware. "The newly developed system uses advanced inverter designs and control techniques to enable efficient heating across different materials, making it a first-of-its-kind solution. This innovation overcomes a major limitation of existing induction cookers," said Vishwanathan. The cooker is designed to be energy-efficient, compact and reliable, while also allowing precise control over power levels. "The prototype has already been tested successfully in laboratory conditions. Its ability to work with commonly used vessels like aluminium and copper could make induction cooking more accessible to a wider section of households," Porpandiselvi added.Beyond convenience, the technology could have broader social benefits. With rising LPG prices and supply concerns, the new system offers a cleaner and potentially more affordable alternative for cooking. It is expected to be particularly useful in rural and semi-urban areas, as well as in student hostels, community kitchens and small food businesses.The research team has also demonstrated strong expertise in induction heating, securing two patents in the field, with another currently under review. To take the innovation forward, a startup — Resoheli Technologies Pvt Ltd — has been set up within the institute's incubation centre. The venture has received seed funding under the Govt of India's MeitY Genesis Scheme, underlining its commercial potential.Efforts are now underway to bring the product to market, with a focus on affordability and large-scale adoption.
