The growing global water crisis necessitates sustainable desalination solutions. Conventional technologies predominantly confront environmental issues such as high emissions from fossil-fuel-driven processes and challenges in managing brine disposal during the operational stages, emphasizing need for renewable environmentally friendly alternatives. This study introduces assesses a bioinspired, solar-driven osmosis device emulating natural of mangroves with effective contaminant rejection notable productivity. bioinspired (BISO) device, integrating membranes, microporous absorbent paper, nanoporous ceramic was evaluated under different conditions. We conducted experiments both controlled outdoor settings, simulating seawater 3.5 wt % NaCl solution. With yield 1.51 kg m–2 h–1 standard solar conditions (one sun), BISO system maintained excellent salt removal accumulation resistance after up to 8 h demonstrated great cavitation even at 58.14 °C. test recorded peak rate 1.22 collected 16.5 mL h, showing its practical application potential. These results highlight device's capability address scarcity using approach, combining design power, presenting viable pathway renewable-energy-driven technology.
