Miniature Nuclear Batteries

The University of Missouri have managed to squeeze technology normally used for spacecraft into something the size of a penny. The BBC's article describes how liquid semiconductors were used inside nuclear batteries instead of solid ones, making them less prone to damage over time from the discharged particles produced as the radioactive isotopes decay. This means that the devices can be made smaller and since the energy produced can last hundreds of years, the potential a alternative energy source is obvious.
