Electromagnetic energy harvester generates electricity from rail-track vibrations
In a world with quickly depleting fossil fuels, looking for alternate ways to generate electricity is the need of the hour! Recently, researchers from the Stony Brook University have come up with a device that generates electricity from vibrations. When extensively used on railways tracks, these simple devices are help generate clean and green renewable electricity!
Currently, these little devices generate electricity in milliwatts. Using the principals of vertical deflection, these electromagnetic energy harvesters could be used extensively, placed between intervals on railway tracks. The energy generated from these could then be used to power on signal lamps, monitoring systems and electronic track switches!
