It uses a gamma ray laser where the tip is ten times as hot as the center of the sun. That's not cold in any meaning of the term!

We have been doing research on laser ignited fusion power for decades now.

That's not what cold fusion is. The idea behind cold fusion is that the whole experiment runs at room temperature, and you don't need gigawatts of power to get it started and keep it going - instead, the geometry of surfaces or solids, or chemistry, or some other phenomenon, brings pairs of "heavy" hydrogen nuclei close enough together than they fuse to become helium.

Given the incredible tininess of nuclei compared to the size of an atom and the rarity of deuterium and tritium, it's very hard to see how that could conceivably happen, and no specific mechanism has been proposed.

Effects continue to be reported by reputable researchers, but they have also been extremely marginal and also lacking any neutron emission, which would seem to be inherent to any fusion reaction.

Further work is needed!
