Random thought....
Polariton "Lasers" at room temperature are possible using Gallium Nitride (not conducive to high concentrations of H or D).

Would a superlattice structure of doped Ni/W layers grown via chemical vapour deposition under high H atmosphere have what it takes to produce catalysed fusion (muon, polariton tunnelling whatever.....)
Anyone with a spare lab and a few millions worth of kit lying around ?
I cant patent this now but hey, it might not work either ......
