Australia mariyu China nunchi ochina engineers oka chinna sponge-like device ni develop chesaru, idi thin air nunchi moisture ni absorb chesi, sunlight tho cup lo water ni release chesthundi. Ee device ni Dr. Derek Hao (RMIT University, Melbourne) mariyu Dr. Junfeng Hou (Zhejiang A&F University) design chesaru.

Ee device, modified balsa wood tho tayaru chesaru – dinilo lithium chloride, iron oxide nanoparticles mariyu carbon nanotube layer untundi. Idi oka sponge la porous structure ni form chesthundi, which pulls water from air even when humidity takkuva ga untundi (30% varaku) and temperature 5°C to 55°C madhya lo untundina sare.
Sunlight padite, sponge collect chesina water ni cup lo release chesthundi. Cup usually dome lid tho and cooling system tho set chesuntaru.
Lab tests lo, ee material 90% humidity lo 1 gram ki 2 ml water collect chesi, 10 hours sunlight lo almost anni release chesthundi. Outdoor lo 94% efficiency tho 2.5 ml per gram collect chesindi. 30% humidity lo kuda 0.6 ml per gram collect chesthundi.
Prototype chala chinnadi – 15 cubic mm size, and 9 sponge cubes (each 0.8g) use chesi oka cycle lo 15 ml drinkable water ni generate cheyyagalugutundi. Eco-friendly and cheap balsa wood valla, idi mass production ki suitable ga design chesaru.
Ee technology drought-prone places and disaster zones lo use cheyyachu, endukante idi sunlight matrame vadutundi and easy to carry. Team ippudu solar panels, thermal storage, and IoT sensors add cheyyadam kosam work chesthondi – automatic 24/7 operation kosam.
Artificial Intelligence ni use chesi, different weather conditions lo performance predict chesi, efficiency ni penchadam kuda chesaru – which makes it better than fog harvesting or radiative cooling methods.
