I had a dream and was compelled to create this drawing  Then I discovered read about it in a previous life |

This is one form of chemical vapor deposition diamond production that has been going on about 30 years. I tried a variation of the early experiments. Did not work too well since I could not afford the proper materials and do I improvised a little too much. Built up too much pressure and before I could get the vacuum system turned back on the thing blew and was all over the walls, ceiling, me... My roommate was not very happy.

Still working on the idea but changed the design on paper. Now I am trying to get funding for the project. The big race right now is to produce diamonds big enough for computer chips since they have maxed out on speed for silicon chips. They are currently doing diamond substrate on silicon, which has increased the speed some, but pure diamond would increase it even more.
It is not hard to do if you have the right equipment. It took me over 20 years to finally realize the key to the whole thing and I smacked myself in the head when I realized how super simple it was all along. I just had to put the pieces together from several decades of diamond research I had noted.

Carbon heavy gas, story says methane works well; hmmmm. My wife says she will cook up a bunch of lima beans, and leave the house before I react and back up to the microwave to fill it. I Should be a natural she says, we're gonna be rich.

Now I am trying to get funding for the project. If you call it "carbon capture" rather than "diamond making" you'll get more funding than you'll know what to do with. |

If you call it "carbon capture" rather than "diamond making" you'll get more funding than you'll know what to do with. That is Soooooooooooo! true. Just a couple of notes on personal experimentation: My wife still has a purple ring on her counter from my first attempt to refine gold. The purple "dye" from disolving gold in Aqua Regia. A little dropped on the counter and the beaker sat in it before I realized it and cleaned up, so nice purple ring. She still speaks to me now and again, sometimes when I wish she wouldn't but that's a different story. My first attempt at refining silver I had no rubber gloves so every where the silver nitrate touched my hands turned black. I had these black spots all over my skin which had to ware off and I got the most entertaining reactions when paying for something and the clerk notices the black spots on the skin. (the black spots were only on my hands and they stopped at my wrists) they would drop the change from 6 inches high and be careful not to touch you for fear of catching something. |

We watched a show on PBS some time back that had to do with mfg. diamonds, very interesting. A tiny diamond seed and a "filler" material were put under great heat and pressure with the resultant diamond being much bigger than the original seed, and same quality as a natural diamond. The story said one of the best "filler" materials is peanut butter, apparently high in carbon per unit volume.

GE was making synthetics starting back in the 1950s. The diamonds were doped with boron to make them in to semiconductors. The process made the diamonds more expensive than the real thing though and fro a long time they could not get over 1 carat. Finally they changed the ratio of the carbon isotopes being used, which stabilized the diamonds so they could go above 1 carat. Others, including DeBeers have also made synthetic diamonds using the high pressure process. The most successful I have heard of so far has been Apollo, who bought the technology from the Russians then computerized the process to get more consistency. |
