Why in news
University of Cambridge researchers developed a living bio-battery using photosynthetic cyanobacteria to provide continuous electricity for low-power electronics.
Background
The bio-battery utilizes cyanobacteria to harness electrons from natural photosynthesis and respiration processes. It is designed to generate a steady electrical current 24/7 without harming the living organisms. The technology aims to replace millions of disposable batteries in low-power devices and remote locations.
Facts for Prelims
- S&TCyanobacteria: Photosynthetic prokaryotic organisms capable of producing oxygen and electricity.
