Cambridge scientists create a living bio-battery that generates electricity around the clock using algae and could replace millions of disposable batteries

Researchers at the University of Cambridge have developed a living bio-battery that generates electricity continuously using photosynthetic algae, offering a potential alternative to millions of disposable batteries used in everyday electronics. Unlike conventional batteries that gradually run out of stored energy, the experimental device harnesses the natural flow of electrons produced by living cyanobacteria during photosynthesis and respiration, allowing it to produce a steady electrical current around the clock without harming the organisms.
