That's great ... though I don't think DeBeers have anything to fear. We already have synthetic diamonds.

Very interesting! Watched the whole video. I bet these little buggers are pretty expensive to create at this point.

They don't explain the electricity producing chemistry.

I guess that the c14 decay releases a beta particle and that becomes current?

It'll be interesting to see if the technical journals follow up with more specific info about the processes involved and the electrical generation aspect. I'd also be interested to learn how this diamond-making process specifically relates to current methods of diamond synthesis. It appears to be similar to the chemical vapor deposition (CVD) method now in widespread use.

In the early days when GE started producing diamonds the cost was more than that of naturally occurring diamonds. But Gemesis is supposedly producing gem quality diamonds for about $5 a carat. Not sure on the cost of chemical vapor deposition diamonds, but the raw materials are very inexpensive. And there are several ways of doing this. Originally they were using heated tungsten coils to knock the carbon out of methane. Then they went to a microwave beam and now I think they are using a laser to do the same thing. But CVD produces diamond coatings microns at a time.

I will read your link later. Thanks!
I wonder what electric energy density is?
ETA
Forbes is awesome.
15 joules per gram. A kilogram will produce some little bit more than a AA battery

This will explain the principle of how the beta particles produce electricity: www.rexresearch.com/nucell/nucell.htmThe Nucell battery is also significantly more powerful. A soup can sized battery produces 75 watts as where a small barrel size 30 inches tall produces 100 kilowatts. I heard there were supposed problems with corrosion, which does not make a lot a sense. But I also heard the military is using the same exact technology so it sounds more like they just did not want a cheap energy source on the market competing with the power companies.
