I hope LENR, once we learn to master it, will create new meta materials that we haven’t known before.
IMO, the reverse is more likely...new meta materials will make lattice confinement fusion possible/more efficient. Pons and Fleischmann used pure palladium, but there is a lot of information showing up that the meta-structure of the lattice is critical.
There are even hints that lattice confinement fusion can happen in the sun, with metallic hydrogen forming the lattice. There is a YouTube video setting out the hypothesis and supporting evidence. Will post link to that in a separate response.
