Green energy or renewable energy is a widely and commonly used terminology when depicting the energy generated from natural resources such as solar, wind, geothermal, biomass and hydropower. One energy resource, in particular, has yet to unleash its potential is the saltwater energy. When salt is dissolved in the water, the ionic compounds of sodium and chlorine are separated, thus allowing the free movement of ions in the solution. This study is the second part of the development phase in producing a low cost saltwater lamp for rural and remote communities in Malaysia. This study specifically focuses on the dimension and geometry of the aluminium electrodes as well as the types of carbon electrodes used. This study is important in determining the most cost effective electrodes to be used in the saltwater lamp.
