What would be the implications of this technology, and when might it be achieved?
What sort of applications could we see in computing, energy, transportation, etc.?
Looking at this graph (from Wikipedia), it might be possible to extrapolate a trend. The description page has explanations for each label colour. Given that room temperature is about 300 kelvin, we can't be far away from a working prototype – 2030 or thereabouts?
I'm a little confused by the materials and physics, etc. so any explanations in layman's terms would be greatly appreciated. This is something I'd love to include on our timeline.
EDIT: I've just noticed the inclusion of gigapascals (GPa) below, so these were obviously done at extreme pressures. In that case, a less energy-intensive version would take a lot longer to be perfected.
