To produce energia it's simpler than you can imagine. A group of students and teachers from Kalindi College at the Indian University of Delhi have come up with an innovative way to exploit thewind energy produced by subway trains.





La speed of convoys therefore it could be exploited to produce electricity. The project, which is part of a group of works on this sector carried out at the Indian university, aims to use the 'wind'produced by the passage of high-speed trains during their daily movements.

The team, consisting of 10 students and two teachers, proposed using strategically placed small turbines to harness energy. Each turbine has a rotor with blades. When the wind hits the blades, they start to move producing mechanical energy. The latter is then converted into electricity, which can be stored in special batteries.

According to the team members who developed the project, i tunnel entry points and the point where the subway moves from an underground line to a surface line are ideal for positioning turbines, as in these areas the wind speed is higher.

“So far we have done the theoretical work using only the train speed data that the Delhi Metro Rail Corporation (DMRC) has provided us with. According to our calculations, a turbine should be able to produce 200 to 500 watts of power per hour "maximizing the power in the sections where the trains reach higher speed, he said Charul Goel, one of the team members.

The DMRC, for its part, has already given students permission to place a turbine, which has been in operation for a few days, in a subway station through a pilot project.

Once the data provided by the pilot project has been collected, the team hopes to expand the potential of the solution to generate around 3 kW of power to produce electricity thanks to the wind.
