Design and Development of Energy Harvesting using Domestic Geyser

Abstract

Energy harvesting is being done through many techniques. Energy is extracted from various unconventional resources including light, heat, etc. Environmental power generation is another alternative word. This research is basically aimed at such a technique, which is rather new in energy harvesting. Basically, the system has four major parts. A domestic water geyser, steam turbine, generator and an energy storage unit. In this technique, domestic water geyser is used for steam production. It is installed in a steam turbine. The shaft is coupled with the generator which produces energy. The energy is stored in the battery afterwards. The turbine is designed in such a way that it increases the overall efficiency of the system. Water is converted into high-pressured steam. The turbine rotor starts to move due to the high pressure. Since its connected to the generator, it produces electric charge. The system is designed in such a way that the turbine has an outlet orifice which is connected back to the water entry pipe assembled against the geyser. The steam leaves through orifice and enters back through the water-inlet pipe. In this way, less energy is wasted which means that the system efficiency increases. The whole design was first simulated using SolidWorks. These simulations helped in designing a proper steam turbine. The design includes dimensions, energy calculations and material selection. Proper operating points have been found using literature study and Hit-and-trial methodology. In the end, results have been shown and discussed as it is a Simulation-based thesis. Different operating points were established. The goal was to design an industrialfriendly system and to provide a supplemental source of electric power to the common man of the country.
