I've seen 40 years of these kinds of claims come and go. If we actually make a massive breakthrough like this, the lab that makes the discovery is going to be incredibly detailed and meticulous, documenting their exact processes, theories, and efforts to reproduce the material(s) from scratch. It's not going to be someone publishing notes with major variances and holes in the details.

I guess what I'm saying is when you see enough perpetual machines published in the news, you start to realize that if someone actually had one the first thing they'd do is make another one to confirm, and then plan which island they're going to buy with their new found riches. And that's to say nothing of whether it's commercially viable on a cost or production speed basis. LOTS of advancements die on those vines. Just look at the semiconductor research industry.
