Emerging energy and water harvesting technologies encompass a suite of materials, devices, and systems designed to capture, convert, and store dispersed environmental resources such as solar radiation, wind, moisture, and ambient heat. Work in this area integrates atmospheric water harvesting architectures, triboelectric and moisture-induced generators, solar thermal and molecular solar thermal storage, barocaloric and magnetic cooling, and long-duration energy storage concepts. These approaches often rely on nanoengineered surfaces, phase-change and barocaloric materials, and hybrid thermodynamic cycles to improve efficiency, reliability, and sustainability of power, cooling, and freshwater supply.
