0.0013 Watts per gram would be about 1 kilowatt per ton. If there were enough of this stuff and it would be easy enough to manufacture, maybe slabs could be installed under peoples' houses as the foundation. How much heat does it take to make a diamond? Would Americium be a more practical source of radioactivity, considering how much infrastructure is already in place for smoke detectors? I'm not really sure what they mean by "radioactive field", there are several different modes of radioactive decay (gamma, beta, alpha). Carbon-14 undergoes beta decay so I assume this is the only decay mode that will work. That would make sense since beta minus decay creates an electron. Americium undergoes alpha decay so if that's how this works, Americium would be no good. This could be used to make ever-luminescent things like road signs or something. Very interesting.
