Introducing speed breaker as a power generation unit for minor needs

Man in his lifetime, uses energy in one form or the other. Energy demand continues to grow, year after year. In the present scenario power becomes major need for human life. But the extensive usage of energy has resulted in an energy crisis, and there is a need to develop methods of optimal utilization, which will not only ease the crisis but also preserve the environment from the negative impacts of global climate change. Energy conservation is the cheapest new source of energy. It is an attractive technology for optimal use of available sources. This research shows the possibility of tapping the wasted energy in the road speed breaker. The wasted energy can be converted to the electrical energy by roller mechanism through several energy conversion processes. In this research, the obtained electrical energy is in KW range which is sufficient to lighten the street lights and traffic signal. As the number of vehicle is increasing day by day, the designed system will be effective to solve the power crisis of Bangladesh to some extent.
