Personal Nuclear Power: New Battery Lasts 12 Years LiveScience

A new type of battery based on the radioactive decay of nuclear material is 10 times more powerful than similar prototypes and should last a decade or more without a charge, scientists announced this week. The longevity would make the battery ideal for use in pacemakers or other surgically implanted devices, developers say, or it might power spacecraft or deep-sea probes. You might also find these nuclear batteries running sensors and other small devices in your home in a few years. Such devices “don’t consume much power,” said University of Rochester electrical engineer Philippe Fauchet.
