Dale in the lab with sky diamonds

Ecotricity founder to grow diamonds 'made entirely from the sky'

Chemical vapor deposition of 'diamond-like carbon' is already a thing, by the way.

Depends if you get the carbon dioxide from the atmosphere which has been exhaled by animals or not.

CVD diamond is amazing as a thermal conductor. I was at a GEC site that used it in the 1990s and they had an open day. The demo was a wire coated in CVD diamond, and you could hold and slice though an ice cube just by melting it with the warmth of your thumb and finger
Have you considered stupidity as an explanation

The claim to 'capture' carbon may be true, but it's definitely over-stated, as the carbon capture is negligible.

If producing 200 carats per month, it'll capture about as much as you produce driving half a mile in a car (assume 40mpg).

But the real comparison should be against mined diamonds, which I understand would use the equivalent of 140,000 miles worth of fuel to extract 200 carats.
My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!
