They are thinking "room temperature" superconductor with metalic hydrogen. Screw diamonds... use graphene.
As matter of fact, screw metallic hydrogen. Use purple bronze in that graphene press.

Red mercury (actually more purple then red) is the stuff made in the Nazi torsion field devices die glocke. Torsion field radiation has strange influence on many substances for example it is possible to produce large quantity's of steel with virtually no carbon and no crystal structure.
Superconductors can make engines smaller and more powerful. Room temperature superconductors would be easier to handle than superconductors that need to be cooled down to liquid nitrogen temperatures. Ceramic superconductors have had a lot of problems for applications because of brittleness and other issues.
Room temperature metal superconductors with very high critical current could make superstrong magnets. Powerful magnets could be used to solve challenges getting to commercial energy generation from nuclear fusion.
ed mercury is a hoax substance of uncertain composition purportedly used in the creation of nuclear bombs, as well as a variety of unrelated weapons systems. In reality, no such substance exists.
It is purported to be mercuric iodide, a poisonous, odorless, tasteless, water-insoluble scarlet-red powder that becomes yellow when heated above 126 °C, due to a thermochromatic change in crystalline structure. However, samples of "red mercury" obtained from arrested would-be terrorists invariably consisted of nothing more than various red dyes or powders of little value, which may have been sold as part of a campaign intended to flush out potential nuclear smugglers.
The "red mercury" hoax was first reported in 1979, and was commonly discussed in the media in the 1990s. Prices as high as $1,800,000 per kilogram were reported.
To create it, Silvera and Dias squeezed a tiny hydrogen sample at 495 gigapascal, or more than 71.7 million pounds-per-square inch - greater than the pressure at the center of the Earth. At those extreme pressures, Silvera explained, solid molecular hydrogen -which consists of molecules on the lattice sites of the solid - breaks down, and the tightly bound molecules dissociate to transforms into atomic hydrogen, which is a metal.
"One prediction that's very important is metallic hydrogen is predicted to be meta-stable," Silvera said. "That means if you take the pressure off, it will stay metallic, similar to the way diamonds form from graphite under intense heat and pressure, but remains a diamond when that pressure and heat is removed."
Understanding whether the material is stable is important, Silvera said, because predictions suggest metallic hydrogen could act as a superconductor at room temperatures.
"That would be revolutionary," he said. "As much as 15 percent of energy is lost to dissipation during transmission, so if you could make wires from this material and use them in the electrical grid, it could change that story."
"Diamonds are polished with diamond powder, and that can gouge out carbon from the surface," Silvera said. "When we looked at the diamond using atomic force microscopy, we found defects, which could cause it to weaken and break."
The solution, he said, was to use a reactive ion etching process to shave a tiny layer - just five microns thick, or about one-tenth of a human hair - from the diamond's surface. The diamonds were then coated with a thin layer of alumina to prevent the hydrogen from diffusing into their crystal structure and embrittling them.
Scientists reportedly say that the world’s only sample of metallic hydrogen, which was touted as potentially revolutionizing technology, has disappeared.
Last month physicists at Harvard University achieved what they described as “the holy grail of high-pressure physics,” when they created the first metallic hydrogen material.
However, Science Alert reports that the sample has disappeared, much to the dismay of experts. The sample was stored at temperatures around -316 degrees Fahrenheit, the report said, noting that the metallic hydrogen was kept at high pressure between two diamonds in a vice-like device.
Earlier this month the vice failed when testing caused the diamonds to break, according to Science Alert, which says that scientists haven’t been able to find a trace of the metallic hydrogen.
“Basically, it’s disappeared,” Isaac Silvera, Harvard’s Thomas D. Cabot Professor of the Natural Sciences, who led the research, told Science Alert. “It’s either someplace at room pressure, very small, or it just turned back into a gas. We don’t know.”
To conduct further tests, Silvera and his [Harvard] team were planning to ship the sample to the synchrotron at the Argonne National Laboratory [in Chicago]. Before they sent it off, they used the low-powered red laser to measure the pressure of the system once more.
But this time, the energy from the laser immediately destroyed the system, and caused one of the diamonds to disintegrate.
"As soon as we turned the light on, 'click', the diamonds broke. One of them catastrophically, it just became powder," explained Silvera.
The researchers, led by Paul Loubeyre at France’s Atomic Energy Commission, first produced solid molecular hydrogen by compressing hydrogen gas between diamond tips to 310 GPa, as has been shown previously by this group and others. Then, they further cranked up the pressure and analyzed how the sample absorbed infrared radiation produced by a particle accelerator in France called the SOLEIL synchrotron. At around 425 GPa and 80 degrees above absolute zero (0 Kelvin, the temperature where all matter has the minimum amount of heat), the sample suddenly started absorbing all of the infrared radiation. This signaled to the researchers that they’d “closed the band gap,” meaning the solid material no longer required an input of energy for its electrons to jump into a state such that they would conduct through the sample.
Basically, the researchers claim that they’ve squeezed the hydrogen gas enough that quantum effects now allow the electrons to flow through the sample as they would in a metal.
