It is difficult to keep a mobile charged when living in an area with frequent power cuts. Gautam faced this problem himself and wondered why the vibration in our voice cannot be used to charge the mobile. He suggests taking vibrational energy created while talking on the phone, routing it through a transformer, diode and condenser and using it to charge the mobile. He feels, “In most villages, we have problems of power shortage. So it can be useful there.” He dreams of being an engineer. Most of his free time is spent tinkering with things in the electric shop run by his grandfather. He is an artist who likes drawing religious figures, with goddess Durga being a favourite.
