Abstract:

A railway track undergoes mechanical vibrations when a train passes. The weight of a train rake is around 40 - 240 tons depending on the type of the train. Assuming the general weight of the train as 80 tons then it is sure that the mechanical vibrations produced are high. So, if we convert these mechanical vibrations into other forms of energy, a lot of energy would be created. Here we can use piezoelectric crystals which will be able to convert these mechanical vibrations into equivalent electrical energy. But the stress directly on the tracks is too large to be made useful for conversion by the use of the piezoelectric crystals because the maximum load that piezoelectric crystals can take is 25000 psi (available in the market). Hence, we are trying to generate electricity using the vibrations on the sleepers beneath the railway tracks because the vibrations, there are reduced and can fall in the range of the available piezoelectric crystals. The electricity thus generated will be in the form of sudden bursts as the pressure is experienced only when the train rake will pass over the plates. A continuous supply of electricity can be obtained by storing these sudden bursts of electricity in batteries and can be utilized as and when required. The frequency of train in Mumbai region is one every three minutes. There are other places with similar high frequency of trains. Such places will be highly benefitted by this concept. Massive wastage of power takes place at railway stations due to continuous and sometimes unnecessary usage of electrical appliances. The power thus generated can be used at nearby railway stations thereby saving precious energy, eliminating transmission losses and saving money as the power is now generated at a cheaper rate. This power generated by this concept can also be used at farms near railway tracks. The power thus generated is pollution free. The future scope of the concept is that we can implement helical coil springs in between the Crystals to generate double the amount of power as previous.
