Researchers at the National Institute of Technology (NIT) Calicut have developed a smart solar stove that could become a practical alternative to LPG cooking, especially during the ongoing fuel shortages in parts of Kerala. The innovation is gaining attention as a potential solution for households and small food vendors facing difficulties due to the LPG crisis.
A Solar-Powered Cooking Solution
The smart stove uses solar panels to generate electricity, which can then be used for cooking. The system is designed to operate using solar power, stored battery energy, or AC electricity, making it flexible for different situations and weather conditions.
The technology was developed by researchers led by Prof. S. Ashok and Dr. V. Karthikeyan, with financial support from the Department of Biotechnology. The project was first introduced in 2022 by the institute’s director, Dr. Prasad Krishna.
Two Models for Different Needs
The researchers created two versions of the smart solar stove:
- Single-burner model
- Double-burner model
Earlier estimates suggested the single-burner model could cost around ₹10,000, while the double-burner version might cost ₹15,000. However, improved versions of the stove may cost ₹30,000–₹35,000, though the price could drop if produced on a large commercial scale.
Improved Design After Testing
The stove was tested in homes and roadside eateries, where it showed promising performance. During early trials, researchers found that the device could heat up after running for several hours. Further research helped solve this issue by improving battery backup and extending operating time.
Following successful trials in different locations, the research team has applied for a patent for the improved solar stove technology.
Safe and Portable Technology
The redesigned stove includes fireproof, waterproof, and shock-resistant safety features, making it safe for use by elderly people and children. The double-burner model also includes a built-in light, which can help street vendors cook at night.
The device is also portable and can be useful for camping, travel, and outdoor cooking, where solar panels can generate electricity for the stove.
Potential Alternative During LPG Shortage
With LPG supply disruptions affecting several sectors in Kerala, innovations like the NIT Calicut smart solar stove could provide an eco-friendly and cost-effective alternative for cooking. If produced commercially, the technology could help reduce dependence on LPG while promoting renewable energy solutions in everyday life.
