Scientists Build a Nuclear-Diamond Battery That Could Power Devices for Thousands of Years

The world's first nuclear-powered battery — a diamond with an embedded radioactive isotope — could power small devices for thousands of years, according to scientists at the UK's University of Bristol.
Long-time Slashdot reader fahrbot-bot shared this report from LiveScience:The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.
