Because, it has a great medicinal value. It is used for different kinds of diseases like dysentery, Cholera, Diarrhea, typhoid, kidney diseases etc. In West Bengal, India there is no alternative way about PathorKuchi leaf for focal medicine. People are using this leaf as a focal medicine there. But now a days it is using to generate electricity for low and medium power production. Generally, Zn and Cu metals is used as an electrode and extract of the PKL juice is used as an electrolyte. To enhance the power of the PKL electricity some secondary salt is used .Copper Sulfate (CuSO 4 ) is one of the important and popular secondary salt for PKL power production. Some Parameters like Load Current, Short Circuit Current, Load Voltage, Open Circuit Voltage, Capacity of the PKL Cell, Voltage Regulation of the Cell, Efficiency of the Cell and Internal Resistance of the Cell Have been studied for immerge depth of the electrodes. The cost of this Power system for practical applications have also been studied. Energy is one of the most essential resources of the present world. We can not imagine the civilization without energy specially electrical energy. In broader sense we can divide electric energy in two types, one is non-renewable energy and the other is renewable energy. Due to the drawbacks of non-renewable energy and advantages of renewable energy, the use of renewable energy is increasing day by day. Eventually new sources and technology is coming out. One of the new technologies of renewable source is the production of electricity from Pathor Kuchi Leaf (PKL), the scientific name of that is Bryophyllum Pinnatum. We can easily produce electricity from PKL by immersing a Zinc and a Copper plate in to the juice of PKL. This system produces theoretically 1.1 volts per cell. So if we need higher voltage or higher current we need to combine more cells to get the desire power.To keep it in mind, In this paper a new approaches is presented to get more power from per cell of the PKL system which is out of traditional cell concept for per cell power. Most of the results have been tabulated and graphically discussed. Keyword: PKL, Construction, Commercial, Electricity, Biomass Energy 1.Objectives i. To generate electricity from an innovative method for the betterment of the mankind. ii. To disseminate this innovative technology to rural people where grid electricity is absent. iii. To popularize this innovative technology to the rural complex area of Bangladesh where grid electricity is still a dream. iv. To reduce environmental pollution using this innovative technology. v. To commercialize the PKL power in the society 2.Introduction Constructing an affordable cost, environment friendly simplified electrical energy source with Pathor Kuchi Leaf for power electrifications which will significantly upgrade the life style of 1.275 billion people in Bangladesh. 1.5 billion people in the world still lack access to electricity-well over of one fifth of the world’s population. Some 85% (1.275 billion) of these people live in rural areas, mainly in Sub-Saharan Africa and
