A new diamond battery that could last for 5,700 years has been developed by researchers from the University of Bristol and UK Atomic Energy Authority. 

Tik tock. That's a reeeeeally long time. 

Unlike traditional batteries, these diamonds don't need to be charged. They harness energy from the radioactive decay of carbon-14, an isotope with a half-life of over 5,000 years. This innovative power source could be ideal for small, critical devices that require constant power, such as pacemakers and space technology. 

While these batteries currently provide only small amounts of energy, they could be invaluable for long-term, remote applications. The diamond structure safely encapsulates the carbon-14, ensuring the battery is secure. 

Additionally, this technology repurposes radioactive waste from nuclear reactors, offering a sustainable solution for managing byproducts. Though not “forever,” these batteries come impressively close—potentially lasting thousands of years, opening up exciting possibilities for future technologies in medicine and beyond.
