Scientists built a battery-free device that turns sunlight into fuel
SMRTR summary
Osaka Metropolitan University researchers built an artificial photosynthesis device that converts sunlight into formic acid fuel without batteries. By embedding a self-regulating electrolyte that automatically adjusts electrical resistance as temperature changes, the system maintains stable fuel production even as sunlight fluctuates throughout the day, cutting costs and complexity.
