NUCLEAR BATTERY COULD LAST A MILLION YEARS

Researchers at the University of Missouri have developed a nuclear battery they say exceeds the energy density of a comparably sized chemical battery by  “six orders of magnitude.” Going back to our high school math, six orders of magnitude comes to an increase of one million times!

So a battery made by their radioactive isotope technique could have the same voltage as a AA battery but last a million times longer. The battery can be made as small as a penny. The researchers say it gives off very little radioactivity and is harmless to the user, say in a cell phone for example.
