Harnessing Plant Bioelectricity through Prickly Pear as Botanical Batteries

Abstract

Plants which are essential for life, have the potential to become a renewable energy source in the Future. They can generate electricity, reducing greenhouse gas emissions and being environmentally friendly. This study aims to explore the untapped potential of botanical batteries and contribute to green energy technology. Plants' capacity to convert sunlight into chemical energy could be a viable and environmentally friendly source for electrical power generation, offering a sustainable solution to the world's growing energy demands while mitigating climate change impacts. To achieve the goal of the study, pure experimental research was applied. And the researchers used cactus (prickly pear), copper nails, zinc nails, copper wire, alligator clips, and disposable plastic containers. The study was conducted at Bayugan National Comprehensive High School, Bayugan City. Throughout the analysis of the data obtained after the three tests conducted, it has been found that like an electrochemical cell, copper and zinc electrodes inserted into prickly pear leaves can generate energy. With the highest current magnitude and maximum value at the highest contact area, the prickly pear plant has the highest potential for energy harvesting. Cut-off or partially leaved leaves can be harvested for their energy, which can then be utilized to charge batteries or power low-power devices.
