Extraction of electrical energy from Aloe barbadensis Miller and Musa acuminate plants

Electricity can be generated through various means, and extraction of electricity from green plants is a developing trend in technology. In this work, electrical energy was extracted from Aloe barbadensis Miller (Aloe Vera) and Musa acuminate (Banana) plants. This was achieved by inserting pairs of electrodes (copper and zinc) into the plants to facilitate ion flow, thereby generating voltage at the electrode terminals. Results of the experiment performed showed that Aloe Vera produced higher voltage 0.83V compared to the Banana plants, which produced a voltage of 0.74V. Furthermore, it was observed that the incorporation of a second and third pair of electrodes within the same leaf branch resulted in voltage of 1.37V and 1.59V respectively for the Aloe barbadensis Miller plant, and 0.86V and 1.11V respectively for the Musa plant, while inserting the second and third electrode pairs in separate leaf branches produced output voltages of 1.4V and 2.01V for the Aloe barbadensis Miller plant and 0.92V and 1.15V for the Musa acuminate plant respectively. Finally, it was proven experimentally that sunlight had very little effect on the output voltage.
