Actually, it looks like even that is not necessary. Dr. George Miley's recent work has shown that once the correct nanostructure is set up, all that is necessary is the pressurize the device with reactant gas, and that the reaction then STARTS SPONTANEOUSLY AT ROOM TEMPERATURE.
It turns out that Miley has been issued THE FIRST US patent on LENR (so it looks like the dam at the Patent Office may have been breached, though perhaps not, as the deadly words "Cold Fusion" don't appear in the patent except in some of the references).
