power generation from train wheels using dynamo
The other day the station master of Sitarampur Railway Station told me that the railway authority had approved the electrification of the route passing through Sitarampur station. I was sitting on my favourite bench on the platform and was thinking over the matter of this electrification. I knew it would take a long time for materialization of this proposed project. Now the trains were pulled by steam engines here. It is good to avoid stream engine considering pollution and the rapid depletion of coal reserve. Even in the United States most electricity generated comes from burning coal? In 2006, nearly half i.e. 49% of the country's 4.1 trillion kilowatt-hours of electricity used coal as its source of energy. The situation is same with diesel driven engines. Moreover India can ill-afford to use diesel for all the railway engines. So electricity is the best option if one can generate it. That was the stream of my thoughts that evening. But India is still a poor generator of electricity she needs badly to meet everyday consumption. It came to my mind suddenly over the possibility of getting electricity from a running train itself. We all know that we need some mechanical energy to move the dynamo for generating electrical energy. So we manipulate in every possible way to utilise constantly all the available means to get mechanical energy. But it is also not easily available situation in any country to get access to some automatic mechanical devices without least compromise. You need coal to produce thermal energy, force of moving water to produce hydroelectricity. And there are some other modes also to move a dynamo like nuclear energy.
