This didn’t start out as a three part series. Finding Rare Earth and other critical elements is serious. We need these constituents for modern devices required to mitigate climate change, like electric vehicles (EVs) and battery energy storage systems (BESS). I would have been really happy if I was able to create one good paper about this search. As it turned out, I wrote the original paper, which outlined this issue and discussed a conventional approach to finding these elements. Shortly thereafter a second source that used an advanced approach (artificial intelligence) to perform the same task appeared. Shortly thereafter I found the information for this third post – a completely different approach as described in the title.
