Lattice assisted nuclear reactions exist. They just don't generate usable amounts of power.

  > Lattice assisted nuclear reactions exist. "Lattice assisted nuclear reactions" is just another name for "cold fusion" (or perhaps a branch of "cold fusion"). All the papers published about this have been unconvincing. > They just don't generate usable amounts of power. All the papers I remember report an small excess of heat. The problem is that heat is very difficult to measure accurately (the different parts of the equipment have different temperatures, estimating the heat transported in convection is a mess, some chemical parts may react, ...)

    There are strong theoretical grounds for lattice assisted fusion. The metal lattice acts to screen the deuterium atoms, and the lattice increases the overall cross section. https://www.sciencedirect.com/science/article/abs/pii/S0168583X17306286 https://www.sciencedirect.com/science/article/abs/pii/S01685... Unfortunately no practical mechanism for creating a self sustaining reaction has been proposed. Although the theoretical benefit has been demonstrated by heating the fuel via hot neutron bombardment. https://journals.aps.org/prc/abstract/10.1103/PhysRevC.101.044609 https://journals.aps.org/prc/abstract/10.1103/PhysRevC.101.0...

      The articles are interesting, but in both case it is not enough the 400°C that they used in this experiment. I think that "cold fusion" is not theoretically impossible. For comparison, "high temperature superconductivity" is also weird, and in 1985 any result about it would have been received with a big dose od skepticism. The problem is that "cold fusion" has a very bad track record in the last years.
