Solar steam generation is considered to be a promising strategy for sustainable clean water supply. An easily made and robust solar still can practically meet any contingency in wilderness survival, compared high-cost delicate thermal materials, example, plasmonic metals, carbon nanotubes, or graphene-based materials. Inspired by rice plants with high transpiration, we develop universal steam-generation device from wasted straw production. The upper leaves of are carbonized composited bacterial cellulose function as superior light absorber the lower culms designed excellent pumps. unique capillary structures multilevel geometrical contribute their outstanding pumping capacity surface evaporation, resulting an evaporation rate 1.2 kg m-2 h-1 75.8% conversion efficiency. straw-derived has daily yield 6.4-7.9 on sunny days 4.6-5.6 cloudy over 14 operation. More attention-grabbing aspect that this applicable various water-bearing media, sand, soil, seawater, collect stable performance, make great contribution unimpeded channels. By turning "waste" "wealth," project shines significant facilely fabricated, robust, efficient still, especially urgent priority survival.
