NIT Warangal researchers develop induction stove compatible with all cookware
HYDERABAD: Researchers at the National Institute of Technology Warangal have developed an induction stove that heats all types of cooking vessels, including aluminium and copper. This marks a significant step forward in kitchen technology.
Professors N Vishwanathan and S Porpandiselvi led the innovation. It tackles a long-standing limitation of conventional induction stoves, which usually work only with iron-based cookware.
New design improves multi-material heating
The team used advanced inverter designs and control techniques to enable efficient heating across different materials. As a result, the system delivers consistent performance regardless of the vessel type. “This innovation overcomes a major limitation of existing induction cookers,” Vishwanathan said.
Moreover, the cooker is compact, energy-efficient, and reliable. It also allows users to control power levels with precision.
Prototype tested, adoption likely to expand
The researchers have already tested the prototype successfully in laboratory conditions. In addition, its compatibility with common vessels like aluminium and copper could make induction cooking more accessible. “This could benefit a wider section of households,” Porpandiselvi said.
Solution amid rising LPG costs
Importantly, the technology could address broader social challenges. With rising liquefied petroleum gas (LPG) prices and supply concerns, it offers a cleaner and more affordable alternative.
Furthermore, the stove could prove especially useful in rural and semi-urban areas. It may also support use in student hostels, community kitchens, and small food businesses.
