Delhi University Students to Harness Wind Energy Produced by Metro Trains

Students of the Kalindi Colege at Delhi University have received approval to pilot a project that will use the high-speed winds  generated by metro trains to produce energy. The team of 10 students and two teachers developed a proposal that consists of small turbines  placed strategically throughout Delhi’s 196-kilometer metro network.
Using the data on the speed of the Delhi  trains provided by the Delhi Metro Rail Corporation, the team was able to pinpoint exact locations for the turbines and predict the project’s efficiency. According to their research, the optimal positions for the turbines would be tunnel entries and transition points where the trains move from the underground to overhead lines.
The harnessed energy would be stored in batteries  and would amount up to 500 Watts per hour (12 kW per day) under ideal conditions, according to the team’s calculations. Estimates show that, with friction and other losses, the turbines might produce 200 Watts per hour (or 4.8 kW in a day) of electricity.
The team was granted permission by the operator of the Delhi metro network to install one turbine in one of the city’s underground stations  as a pilot project.
