DU college harnesses wind energy churned out by Metro trains

Students and teachers of Kalindi College, Delhi University, have come up with an innovative way to harness wind energy produced by Metro trains.
The project, a part of the university’s Innovation Projects Scheme, aims to use the high speed winds produced by trains, as they move, for electricity.

 

The team, which consists of 10 students and two teachers, has proposed using small turbines that are placed strategically to tap the energy.

A turbine has a rotator with blades attached to it. When the wind strikes the blades, they start moving and mechanical energy is produced. This mechanical energy is then converted into electrical energy which can be stored in batteries.

According to the members of the team that has come up with the plan, entry points of tunnels and the point where the metro moves from an underground line to an overhead line are ideal to place the turbines as the wind speed is higher here.
