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.
