A team of physicists and chemists from the University of Bristol has developed man-made prototypes of a ‘diamond battery’ that is able to generate a small electrical current when in contact with radioactive particles. By using irradiated carbon-14 from decommissioned nuclear stations, which has a half-life of 5,730 years, these batteries could potentially provide micro power beyond what humans can imagine. The shortest lifespan according to the team is about 12.4 years and the longest up to 5,000 years. During this project, the scientists have come up with four battery types, three of which are beta voltaic and one gamma voltaic type, all of which harvest particles in different ways and have various applications.
