Hybrid Energy Harvesting using Piezoelectric Materials,Automatic Rotational Solar Panel, Vertical Axis Wind Turbine

Abstract In recent years we are facing the power cut problems due to increasing demand of electricity, due to the development of industrial automation that requires huge power. Multinational companies (MNCs) also need certain Mega Watt (MW) interruption free power supply. This means that we may experience power cut much more than 60% in the short future. To compensate this power demand, power production through hybrid energy harvesting from piezoelectric material, rotational solar panel(sun tracking) and vertical axis wind turbine methods are used. These concepts can be used separately or combined depending upon electric power requirement. This project is used to power up the domestic houses and to power up the street lights in two-way roads. Piezoelectric materials are integrated and placed beneath the road for a particular distance from the street light. Due to mechanical stress produced by the vehicle, piezoelectric material produces electrical energy which is then it is stored in grid battery. In Rotational solar panel method, pendulum concept is used to rotate the solar panel to track the sun. The aim of this is to get the maximum energy with little use of solar panel. This model has an escapement wheel and a pendulum. A hanging weight transfers energy to an escapement wheel, which is released periodically by a swinging pendulum. So that the panel attached to shaft tracks the sun. Power produced from this is also stored in the same battery through charge controller. Vertical axis wind turbine is placed between the two way roads. Opposite motion of vehicle on two ways road induces a rotational force on the turbine which in turn produces an electric power. This power is also stored in the same battery. The battery is then discharged to power up the street lights. Same set up is built on the roof top of the houses, so that hybrid energy produced from these is used to power the domestic houses. This idea makes the domestic houses and street light to be independent of Electricity Board power supply.
