Fifteen-year-old Tripura schoolboy Parinaha Chakraborty has come up with an innovative way of using a windmill to generate electricity that can light up bulbs inside a moving train. Parinaha came up with the idea after travelling on a meter gauge train that did not have electricity, water or toilet facilities — even though such trains cover distances upto 200 km, often at night.
“The conventional energy mechanism is obsolete in these trains,” says Parinaha, who travelled with his parents from Agartala to Dharmanagar on the northern end of Tripura last year sitting in one such train in pitch darkness.
That’s when he started thinking how to improve the lighting. Last December, he hit upon the solution — an incredibly simple and effective one — that involves installing a windmill in front of the train. Using the speed of the train, the windmill produces mechanical energy which can easily be converted into electrical energy that can light up low voltage bulbs inside the train.
