Experimental Study of Earth Batteries

Abstract

Earth batteries have been successfully built and operated as an alternative source of low-power electric supply. Different electrode configurations were tested for the greatest possible variation in potential. The most appropriate combinations of frequently accessible metals were chosen for more thorough characteristic investigations in light of robust and cost-effective application of this natural power technology by untrained village customers. Each cell produced a voltage of 2.05, 1.40, 1.10, and 0.9 volts when the anode and cathode were made of Magnesium, Zinc, Aluminum, and Carbon, respectively. One Zn-Cu cell was found to have an average rated power of a few tens of microampere. When it came to low-power electronic products like mobile phones and white-light LED calculators and wristwatches, the site had them all. Using many earth battery cells in series like a commercial lead acid battery resulted in a linear rise in the voltage. The load current was found to rise by connecting earth cells in parallel. Furthermore, increasing the electrode surface area was shown to boost source current capacity. However, single cell voltage was shown to stay consistent independent of the electrode diameters. According to this research, the most cost-effective metal electrodes for earth batteries have been studied. Operation of earth batteries as a free power source was proved effectively
