Dangling strings slash the time and space needed for lithium harvesting

Although lithium can be found in hard mineral ores, it's more often extracted from very salty (aka briny) groundwater. The latter task could soon be much quicker and eco-friendlier, thanks to a new string-based extraction technique.
