The University of Missouri has developed tiny penny-sized nuclear batteries with one million times the output of a conventional chemical battery. Some major differences between the liquid semiconductor core and other solid core nuclear batteries are their shelf life and their size.
Imagine the possibilities for future technology, space flight, medicine, or, for that matter, never having to remember to charge your iPod!
Implications - The idea of penny-sized power revolves around the use of radioactive materials, but are said to be completely safe if used normally. Batteries are definitely important in many aspects of life since doctors use them at hospitals during surgery and people need them to drive their cars.
