Victor Christianto In previous article, we reported initial findings based on small experiment on potential use of salt- water as cheap source of renewable battery with various kind of metals as anode and cathode. The purpose of these experiments is to find out which combination of anode and cathode is capable to generate the best performance in terms of electric voltage. Following that previous             reports, we tried to conduct further simple experiments on possible effect of low intensity laser irradiation on potable water’s electrical features. Nonetheless, this report is slightly disappointing, because as an effect, there is no increase of water electrical feature, instead it may support initial reports by others such as Cohen Tannoudji, Alain Aspect et al, on laser cooling effect to molecules [3][4]. 2022 2022 16 22 10.54216/JCFA.020103 https://www.americaspg.com/articleinfo/32/show/1455
