Whooshing wind from passing trains can now be used to produce electricity.

Two designers from China have developed a device called T-Box which captures  wind from trains and converts it to electricity. Partly buried in between the rails, the device has a turbine that spins as the wind passes. A turbine is a machine that produces energy by spinning.

According to its designers, 150 T-Boxes can be installed in almost 1 km of railway. A high-speed train which normally runs at 125 mph can produce at least 3,500 watts, the same power produced by a small electric generator.

A train with a speed of 187 mph running on less than 1 km of rail can produce 2,600 watts. This amount of energy is enough to supply 40% to 100% of electricity in one house.

The T-box won a silver medal in innovation and was put on display in a learning institute in Taiwan.

The energy produced by T-boxes can be used to provide much needed electricity to remote places in China and perhaps other parts of the world.
