Imagine a battery that lasts for thousands of years—sounds like science fiction, right? Well, it’s becoming a reality thanks to the UK Atomic Energy Authority and the University of Bristol. They’ve developed a diamond battery powered by carbon-14 decay. This innovative technology could revolutionize how we think about energy sources, particularly for medical implants and other devices that need long-lasting power without frequent replacements.
