Abstract: Due to limited availability and risk of extraction of non-renewable natural resources for energy extraction and production of electricity in future we will be relying on various renewable energy resources. Therefore we intent to aid THE GRAVITATIONAL VORTEX TURBINE SYSTEM in the field of hydro electricity generation. The turbine is capable of generating clean energy from streams without interfering with the environment. It will be capable if converting energy of moving fluid to kinetic energy which can be further utilized to convert it into electrical energy using a low hydraulic head. Electrical power is essential in commercial and social investments like lighting, heating, communications, Computers, industrial equipment, transport etc. Therefore hydropower energy is one of the most suitable and efficient source of renewable energy which depends on more than century of experience for this issue. The power capacity and facility are two criteria required for the classification of hydropower plant. The first one consists of five technologies: dammed reservoir, run of river, pumped storage, in stream technology and new technology gravitational vortex. The other one is classified according to power scale is Large, Small, Micro and Pico Hydropower. This project is focusing on micro hydropower especially gravitational vortex power which increases the sustainability and health of the water as a whole. It presents an overview from both flow and power points of view by discussing the free surface vortex (FSV) and the suitable turbine systems which are used in micro hydropower. The use of subjects like Fluid mechanics, Theory of machines and Engineering Mechanics will provide a backbone of this project. From this Project we will illustrate the micro hydro power generation technique.
