Scientists built a battery-free device that turns sunlight into fuel

science

According to ScienceDaily, researchers have created an artificial photosynthesis system that solves a persistent problem: the need for batteries. The breakthrough is an electrolyzer that self-regulates by automatically adjusting its electrical properties as sunlight fluctuates and it heats up. This keeps solar fuel production stable and efficient while eliminating the cost and complexity of traditional battery-dependent systems.
