| The BBC wrote: | Researchers have demonstrated a penny-sized "nuclear battery" that produces energy from the decay of radioisotopes.
...
The University of Missouri team says that the batteries hold a million times as much charge as standard batteries. |
bolding mine, for gloating |

Yeah, but no one on the team is actually from Misery.

| Is that radiothermal or betavoltaic? |

| I'd imagine it's a betavoltaic device as it relies on a semiconductor capture medium. |

I figured, just wanted to be certain that the BBC wasn't confusing the Seebeck effect for betavoltaic, since you can use semiconductors in those too and both are used with nuclear power sources to convert waste products (heat for one, electrons in the other) into useful electricity.
I was under the impression that the Seebeck effect was used more often, even in the pacemakers it mentioned, so when they said "Most nuclear batteries..." it threw me off. |

Nuclear batteries will be the gravest threat to international peace since the Playstation 2.
