Scientists at the University of Bristol and the UK Atomic Energy Authority have developed the carbon-14 diamond battery, a groundbreaking energy source capable of lasting thousands of years. This innovative battery generates electricity through the radioactive decay of carbon-14, safely encased in diamond to block harmful emissions. With a half-life of 5,700 years, it offers an ideal power solution for applications like medical implants, space exploration, and remote devices. Furthermore, this technology repurposes radioactive graphite waste from nuclear reactors, addressing nuclear waste challenges while providing an exceptionally durable and sustainable power source.
