Using the "trio" of light, heat, and salt water evaporation, a silicon nanometer "environmental generator" achieves continuous and stable power supply.

Using only sunlight, saltwater, and heat to power a large number of wearable devices or Internet of Things may sound like a fantasy of the future, but scientists at the Swiss Federal Institute of Technology in Lausanne are turning it into reality. They have ingeniously designed a three-layer silicon nano "environmental generator" that harnesses the "triple play" of light, heat, and saltwater evaporation in the environment to achieve continuous and stable electricity production. The related research is seen as a significant advancement in the field of water-vapor power generation and has been published in the latest issue of "Nature Communications."
