This research has been highlighted in the Nikkei. My interview has been published in the newspaper highlighting the PMFC. My interview has also telecast in the FM Kirara radio. Bioelectricity generation from big tree microbial fuel cell has been studied for this current research. There was 2 big Challenges during this research:1. How to place/set up the plant microbial fuel cell in a grown up tree? As the root systems of a big tree has already grown up, it is impossible to set the anode under the root system of a tree.2. How to increase the amount of generation of voltage and power from a big tree?The last year's research, we used two different types of big tree named Kurogane and Mukonoki for the research. It has chosen because the Kurogane is an ever green tree and Mukonoki is deciduous tree. The evergreen plant can generate more electricity throughout the year. However, the deciduous trees can generate less electricity due to its fallen leaves and change of color during the winter or the autumn time.For the first challenge, we set up bio-battery surrounding the tree. The biobattery were connected with the series connection. The food for the bacteria will be received by the help of the root extrudates. It was found that the bioelectricity can be generated from the big tree. The amount of the maximum voltage generation is 100000mV from one tree of Kurogane. However, it was seen that the for the Mukonoki, the voltage generation slightly dropped from the autumn and from the winter when the color of the trees started to change and the fallen down.
