Electricity generated using air power harnessed from speeding trains

We are living in an age where solar power and wind power have become routine, but here is something that is just out of the box. A 38-year-old entrepreneur, who runs a group of engineering and mechanical units, has come up with an innovative technique to harness the wind pressure on a moving train to generate power. His system has the capability to produce 14.81-lakh megawatt (MW) of power in India alone, with its 63,000 route kilometers of railways and 14,300 trains operating daily.

Santosh Pradhan’s unique technology utilizes the immense air pressure that is created when a train runs at a speed of 110-120km. What he has done is he has attached a small impeller at the front portion of train and one on top of each coach of a train. As the train moves, it generates large amount of compressed air due to high velocity of the wind. This compressed air is accumulated in large fabricated tanks placed on either side of the track and can be used to rotate turbines or air turbine motors, which can produce a considerable amount of electricity.

Although Pradhan has is still waiting for consent from the government, 20 of his patents have already been registered. Claims are that this technology is capable of saving nearly 2,586 million tons of carbon dioxide emission for the country. He has even obtained 22 national and international patents for the concept.
