Modelling of pandanus amaryllifolius plant-microbial fuel cell as low power generation source with energy yield enhancement

Research on alternative renewable energy resources that are pollution-free have been conducted since last decade, whereas the existing conventional energy resources are depleting. Among the emerging energy resources is living plants energy. However, plant-based energy harvesting technology is...
