Assessing The Performance of the W.A.L.B. (Water-Generated LED Bulb) Device Powered by Saline Solution

The study titled “Assessing the Performance of the W.A.L.B. (Water-Generated LED Bulb) Device Powered by Saline Solution” evaluated the efficacy of the W.A.L.B. device, focusing on the relationship between iodized salt concentration, brightness output, and longevity. This research sought to address energy challenges faced by communities in remote areas. To meet its objectives, the researchers tested three W.A.L.B. devices with varying concentrations of salt (1000 g, 2000 g, and 3000 g), maintaining a constant water level of 200 ml. The methodology included constructing and testing the devices, measuring brightness using a light meter app, and timing their operational duration. Brightness was quantified in lumens, and runtime was recorded to evaluate longevity. The research was conducted in three phases: constructing the W.A.L.B. devices with copper wire, electrodes, and a 3-watt Delta Lighting DC LED bulb; preparing saline solutions with designated iodized salt concentrations; and performing experiments to observe brightness and runtime. An observational checklist was utilized to ensure the accuracy of the results. Findings indicated that higher salt concentrations enhanced brightness stability and longevity. W.A.L.B. 3, with 3000 g of iodized salt, achieved an initial brightness of 10.26 lumens, stabilizing at 2.64 lumens for 54 minutes. In contrast, W.A.L.B. 1 and W.A.L.B. 2 demonstrated shorter runtimes and less stability in brightness. This study highlights the potential of the W.A.L.B. device as a sustainable energy source for lighting in remote and disaster-affected areas and advocates for further research into water-powered technologies.
