Descrição: The solar steam process, akin to the natural water cycle, is considered to be an attractive approach to address water scarcity issues globally. However, water extraction from groundwater, for example, has not been demonstrated using these existing technologies. Additionally, there are major unaddressed challenges in extracting potable water from seawater including salt accumulation and long‐term evaporation stability, which warrant further investigation. Herein, a high‐performance solar steam device composed entirely of natural wood is reported. The pristine, natural wood is cut along the transverse direction and the top surface is carbonized to create a unique bilayer structure. This tree‐inspired design offers distinct advantages for water extraction, including rapid water transport and evaporation in the mesoporous wood, high light absorption (≈99%) within the surface carbonized open wood channels, a low thermal conductivity to avoid thermal loss, and cost effectiveness. The device also exhibits long‐term stability in seawater without salt accumulation as well as high performance for underground water extraction. The tree‐inspired design offers an inexpensive and scalable solar energy harvesting and steam generation technology that can provide clean water globally, especially for rural or remote areas where water is not only scarce but also limited by water extraction materials and methods. A bilayer tree‐inspired design is fabricated for application as high‐performance solar steam‐generation device. The all‐wood device demonstrates high efficiency in water extraction from both seawater and groundwater, long‐term stability in seawater without salt accumulation, and maintains production cost as low as ≈$1 m−2.
