Abstract

There has been a major increase in the global demand for energy in recent years as a result of industrial development and population growth. In Malaysia, studies have shown that electricity demand in Malaysia is on the rise, having gone from a weekly peak demand of 14,245MW in the last quarter of 2009 to 15,476MW in May 2011. This is expected to rise to more than 16,000MW in 2012, and to 20,847MW in 2020 and will continue to grow by about 3% every year until 2030 when it will reach 24,770MW. In this project, I have looked for other alternative to tackle the forthcoming electricity crisis by using salt. Beside making the food tastier salt is found to be able to generate electric energy. However, correlation between salt and electric energy is not well documented yet. Therefore, in this project such correlation will be investigated in two different angles, i.e., the size of electrodes used and the types of salt. This project is limited to 1 kilogram of salt. Each increment of salinity will be measured in 4 sizes of electrode (3cmx3cm, 5cmx5cm, 7cmx7cm and 9cmx9cm) and 3 types of salt (white, coarse and fine) used. I have found that the obtained voltage was increased as salt quantity (salinity) increased. Fine salt produce higher voltage in short period of time as compare to coarse salt as it is easily soluble in water and the chemical reaction was very fast compare to large size of salt as in coarse salt. White salt has small size which makes it soluble in water fast but that type of salt used as ingredient in foods where it has 20% less Sodium compare to other type of salt. These characteristic makes white salt produce low voltage compare to coarse salt and fine salt. The size of electrodes (aluminium and copper) was not significant with the correlation as there was no different in term of voltage produced in between different sizes of electrodes used. The results are visualised by using a visual basic interface which is informative, interactive and user friendly. Such findings could be useful for the development of the alternative energy using salt.
