Tritium

When your cellphone explodes you're probably going to need a hazmat team in addition to an EMT, but researchers at the University of Rochester have developed a prototype for a new kind of battery that generates power by using silicon to capture electrons emitted from a radioactive gas (in this case, tritium, which is actually one of the least dangerous radionuclides out there). There's already a company called BetaBatt which is working on ways to commercialize the technology.
