Smaller And More Efficient Nuclear Battery Created

"As radioactive substances decay, they release charged particles that when properly harvested can create an electrical current."

Cool. Plus these nuclear batteries hold a million times more charge than regular batteries. Hopefully this will lead to more efficient batteries to store renewable energy (solar, wind, etc.) that is only created at certain times of the day. If we want to reduce our consumption of coal to meet our base load electricity needs then one of the things we have to do is figure out an efficient storage mechanism to store the renewable energy that was created at peak solar and wind times. There are two good articles if you want to read more about this technology, one at the BBC and one at Science Daily.
