Evaporation‐Driven Dual‐Function Wood Composites: Integrating Hydrovoltaic Generation and Thermal Management in Architectural Applications

) and maintains ≈2.1 °C night-time temperature reduction. A proof-of-concept, a metasequoia wood cabin prototype, generates power and cools simultaneously. Yangzhou tests show ≈1580-1630 mV output and ≈4.9 °C/1.1 °C day/night cooling, proving sustainable architecture viability. This work innovates sustainable energy-water technologies, enabling off-grid power and passive cooling for self-sufficient architectures.
