Novel Approach to Harvest Energy from Salinity Gradient

Abstract

The paper focuses on harvesting energy from an energy source consisting of electrolytic solution and electrodes. The design focuses on using different ionized chemicals as electrolytes, which includes NaCl in Faucet water, Vinegar and Electrodes including Zinc, Copper, Magnesium, Graphite, Aluminium. The cells are arranged in cascade and parallel setup, and the voltage, current values are noted and studied using a Multimeter. Results depict that the energy produced from different electrolytes and electrode combinations vary based on the reactivity of the element, which can be referred from the electrochemical series. Alongside the thought of the device operation, aspect, overall expenditure a six-celled Graphite Magnesium Electrolytic-cell battery in a cascade configuration, using NaCl-water-electrolyte produced a voltage of 9.0 volts for seventeen hours further can be improvised by changing electrolyte. The device designed can be used to activate an LED lamp.
