I was trying to explain this to someone a couple of days ago. This article definitely helps! I'm pretty excited to see if this is successfully verified or not and it seems we won't have to wait long! This, plus the confirmation of energy positive cold fusion within the last couple of years could really be the defining moments between our current level of advancement and a big step forward.
I appreciate this approach to science writing. Gives context and conveys excitement about the science being done, without resorting to hyperbole about how this is guaranteed to change the world as we know it. And very well distilled for someone like me with no background in materials science!
Apparently the materials aren't extraordinarily rare and the process to create it isn't too mindboggling. It should be possible for other labs to produce and test.
