A pair of tweezers squeezes water from the spongy material developed by the team. (Credit: Xingying Zhang) In a nutshell This wood-based material can pull water directly from air using only sunlight, working even in arid regions with humidity as low as 30% and in freezing temperatures down to -20°C. The device captured 2.5 milliliters of water per gram overnight in real-world testing, releasing it when exposed to sunlight with 94% efficiency. Made from affordable materials like balsa wood and lithium chloride, this technology could provide clean drinking water in areas lacking infrastructure or during emergencies. **************************************************************************** MELBOURNE — Love...
