Scientists from the UK Atomic Energy Authority and the University of Bristol have developed the world’s first carbon-14 diamond battery, capable of generating power for over 5,700 years. This groundbreaking technology harnesses energy from the radioactive decay of carbon-14, an isotope extracted from nuclear waste graphite blocks. The carbon-14 is encapsulated within synthetic diamonds, which safely contain the radiation while converting the emitted electrons into a steady electrical current.
Functioning similarly to a solar panel—but using electrons instead of photons—this battery offers a continuous, maintenance-free power source. Its extreme longevity and reliability make it ideal for powering space missions, remote sensors, and medical devices like pacemakers, where battery replacement is difficult or impossible.
In addition to its performance, the diamond battery provides a sustainable solution to nuclear waste by repurposing radioactive material that would otherwise require secure storage for thousands of years. This innovation is a major leap forward in both clean energy technology and environmental responsibility.
