Researchers at Ohio State University have created a battery, just 4 cubic centimeters (0.24 cubic inches) big, that can convert nuclear energy into electricity via light emission. Although they run off radioactive sources, the batteries themselves do not contain any radioactive materials, so they are also safe to touch. The researchers have shown that ambient gamma radiation (harmful ionizing radiation) could be harvested from nuclear waste using a combination of scintillator crystals (which emit light when they absorb ionizing radiation) … read more »
