In this prototype carbon capture apparatus, a solution of potassium hydroxide is wicked up into polypropylene fibres; circulating air evaporates the water in the solution, concentrating it to very high levels. The white crystals are nearly pure potassium carbonate, formed from carbon removed directly from air. (photo by Dongha Kim)

New ‘rock candy’ technique offers a simpler, less costly way to capture carbon directly from air
