Nuclear Battery That Runs 10 Years

Jenny writes "A battery with a lifespan measured in decades is in development at the University of Rochester, as scientists demonstrate a new fabrication method that in its roughest form is already 10 times more efficient than current nuclear batteries -- and has the potential to be nearly 200 times more efficient. Similar to the way solar panels work by catching photons from the sun and turning them into current, the science of betavoltaics uses silicon to capture electrons emitted from a radioactive gas, such as tritium, to form a current. As the electrons strike a special pair of layers called a 'p-n junction,' a current results. I can imagine lots of applications for this new battery including my own laptop."

    it would be perfect for medical devices like pacemakers, implanted defibrillators, or other implanted devices

    Well, I suppose that's ok then, but it won't stop the jokes.

    On the other hand, I wouldn't mind some grammar nazi slamming TFA for using "implanted" redundantly and confusingly, as if pacemakers might not all be implanted.

    Why ask for "flamebait" or "troll" when clearly "offtopic" trumps those classifications?
