The field has expanded from deuterium in palladium to also include hydrogen in nickel and nickel nano-powder, low energy glow discharge, and transmutation experiments (mostly in Japan). Research funding sources in the US include the Defense Advanced Research Projects Administration (DARPA), and the Department of Defense, Threat Reduction Agency. | The field has expanded from deuterium in palladium to also include hydrogen in nickel and nickel nano-powder, low energy glow discharge, and transmutation experiments (mostly in Japan).
