Inspired by nature, technology returns to its roots. As the name suggests, a saltwater lamp is a lighting device that generates electricity solely through an electrochemical reaction between saltwater and metal electrodes. Its core technology isn't intricate engineering, but rather cleverly utilizes the principles of electrolytes. Simply adding a small amount of salt and water to the lamp generates enough energy to power efficient LEDs and a USB charging port. A single lamp boasts a lifespan of thousands of hours, and the resulting wastewater is completely environmentally friendly.
