Pranjal Srivastava, a class 10 student from Lucknow has invented a 'thermoelectric stove generator' which can cook food and charge a mobile phone simultaneously.
The device taps waste energy and convert it into electrical energy. The energy produced is stored in supercapacitor. It has a USB port to harness the power generated. The cost of building the device was Rs 400.
Pranjal took six months to build the stove and two years to test it for safety measures. He was inspired by the use of kerosene lamps during a power cut. Pranjal's research has received Standard National Inspire Awards and Student innovation Competition in the Philippines.
