If they manage to produce more wattage, then it can work, ink device or something with low power usage could benefit from this. Get a texting device like blackberry that will always work, that would be epic.

I get that they are confident they can produce more power, but usually these diamond/nuclear batteries produce really small amount of power.

Why phones? I want nuclear powered electric vehicles . If you could even get an EV with the performance of a Prius that never needed gas or a charge for 250,000 miles, that would be a major accomplishment.

I've been on one. Aircraft carrier.

And most likely always hot.

The nuclear process can most likely not be controlled, and will just provide energy the whole day long. A small sidecar battery may hold charge for peak usage, but still the nuclear battery have to churn atoms all the time to provide the mean power. And the conversion process usually is not very efficient either (but I don't see numbers for this particular device).

I find it a bit worrying how science-illiterate the some "tech" reporters appear to be (calling Nickel-63 "63 nuclear isotopes").

Also 50 Ci is an awful lot of activity to produce 100 µW. Being anywhere near a hypothetical 1W version would be quite scary.
