Radioactive Diamond Batteries That Last for Thousands of Years

A pair of researchers from the University of Bristol have formed a company called Arkenlight to try to make diamond batteries out of nuclear waste that can potentially power devices for thousands of years. The betavoltaic batteries work by releasing beta radiation, which excites semiconductor material to produce electricity. These types of batteries don’t put out much power — they can’t replace your iPhone battery for example — but they do their thing for a loooong time. Arkenlight is focused...
