Beacon is a new conceptual device that provides illumination using the power of salt water. Ideal for areas close to the sea, the design utilizes a galvanic cell battery system and only requires refilling with salt water. Unlike kerosene or oil lamps which pollute the air and are dangerous, this design is so safe to use that even kids can operate it.
A galvanic cell can be created by using zinc and copper. The anode is a zinc bar placed into a zinc sulfate solution and the cathode is a copper bar placed in a copper (II) suphate solution. The two solutions are connected by a porous sodium chloride salt bridge.
Galvanic Cells (Voltaic Cells) All about Galvanic Cells, which are also called Voltaic Cells. These are devices that use a chemical reaction to create electricity. Moving electrons create electricity, and electrons flow from the anode, the site of oxidation, to the cathode, the site of reduction. The galvanic or voltaic cell also includes a salt bridge, which helps to balance charge, and lets ions move between the two half cells. In this video, w
