Vapor accumulation often limits the performance of passive interfacial solar evaporation. Inspired by the Dyson sphere concept, Xu, Yang, and co‐workers designed a perforated‐shell evaporator with an internal non‐evaporating core that diverts incident sunlight to drive self‐generated internal convection for vapor removal. This strategy provides a versatile pathway for enhancing interfacial mass transfer in sustainable solar to water technologies.
