Abstract
new generation of products that generate their energy from their local environment, rather than relying on conventional batteries. The world needs us to develop products that use energy harvesting as the base for powering low-power electronic devices. We and the world cannot afford not to ignore the subtle demand of this need.
This study aims to develop a system where the input power comes from self-powered water flow energy harvesting system. This Water flow harvesting system has been designed using a water pump and Pelton wheel turbine, which enables us to transform kinetic energy of the water flow into electrical energy which is further used to power low power electronic devices and sensors. These specialized hydro-systems can operate in a variety of head and flow conditions depending upon the water flow rate. The water flow energy harvesting system and water pressure fluctuation introduced during the testing and the analysis of the project is also used to generate small amount of power. The output produced through the energy harvesting system is predicted to be about 1.87W as per the results achieved which is good enough to run the low power electronic devices.
That raises the question of what basically is Energy Harvesting? Energy harvesting could be termed as a process of extracting and converting the ambient energy when it is easily accessible into its usable form such as electrical energy e.g., Wind Energy Harvesting. Energy harvesting is important as it provides an alternative power source for electronic devices where traditional energy sources are not available. This technology, can be extended to devices in the IoT which eliminates network-based energy and conventional batteries, minimizes maintenance costs, eliminates cables and batteries, and is environmentally friendly. Energy generation promotes environmentally friendly technologies that save energy and make this technology indispensable for achieving next-generation smart cities and sustainable society. Previously, solar energy and mechanical energy were two of the most important and only known sources used to produce energy. However, the surge in demand has led to a growing focus on the science that aims to extract energy from various sources such as wind, geothermal, rain, or other natural vibrations. Piezo-electric, thermoelectric are also the techniques that have been used in the past to contribute to the research in this field. The researchers lately introduced such energy harvesting networks that can harvest electromagnetic waves as well as radio waves into electrical energy for power generation The decision about using the harvesting method depends on the location and the application involved. The difference lies in the amount of energy produced with each of the different technique. The table given below depicts the Power Density in different energy harvesting methods.

INTRODUCTION The extraction of energy from non-conventional sources in the environment has received increasing attention over the past decade by researchers studying these alternative energy sources for low power consumption applications. The researchers constantly aim at figuring out recent advancements in the field of energy harvesting. There is a lot of wasted energy in the environment which can be converted to its useful form and showcasing it as a potentially cheap source of power. With the advent growth of technology in the 21st century, we have arrived at a point where many of today's more efficient battery technologies use elements such as lithium, which are often quite rare considering the demand for chemicals for industrial purposes. Today we have to think about how we can manufacture these materials looking at the human needs and, perhaps more importantly, how we can dispose of them at the end of their useful life. The demand for these materials is increasing exponentially with the demand for the materials required to manufacture them. Concerns have been constantly raised about the fate of the planet, not only about how we can fulfil the demand but also about its impact on the world. What the world needs now is a
