Wind Tunnel that Produces Power from Passing Subway Trains

In order to tackle the vehicular traffic problem, cities around the world are building underground subway systems that would cut the number of vehicles on the roads.

But in addition to reducing the amount of cars on city streets, Korean designers Sinhyung Cho, Hong Sun Hye and Ryu Chan Hyeon thought about creating a conceptual underground system that would generate renewable energy.

The team designed an underground tunnel for big cities. The futuristic tunnel is able to produce clean energy by making use of the wind power that is generated by passing subway trains, informs Designboom.

Designers called their project simply the Wind Tunnel. The power obtained from the system can be then used to electrify a number of facilities located on the ground.
