Around the world, research teams are addressing the rising global demand of water via the development of sustainable and straightforward technologies that make use of what nature has to offer. Researchers have now reported a hydrophilic and self-floating photothermal foam that shows high-rate evaporation without additional components, enabling an elegant and simple approach for water harvesting through solar evaporation. This photothermal foam enables an elegant and simple approach for water harvesting by utilizing energy from natural sunlight.
