Personal Nuclear Power: New Battery Lasts 12 Years

Personal Nuclear Power: New Battery Lasts 12 Years
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, "and yet having to replace the battery every so often is a real pain in the neck."
Fauchet told LiveScience the batteries could last a dozen years. They're being developed at Rochester and the technology has been licensed by BetaBatt Inc.

Doesn't seem to have much power output but a 12 year battery is ok in my book.
