Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.
The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8%…
