I knew about the nuclear batteries in space, but isn't the new thing here the miniaturization and safety?
> Carbon-14 was chosen as a source material because it emits a short-range radiation, which is quickly absorbed by any solid material. This would make it dangerous to ingest or touch with your naked skin, but safely held within diamond, no short-range radiation can escape. In fact, diamond is the hardest substance known to man, there is literally nothing we could use that could offer more protection.
That sounds really promising to me. And I wonder if there is some more optimal lattice structure, or some way to scale it up and produce enough energy to power a smartphone.
