Of special interest - in the event that Rossi's (misnamed) "catalyst" is shown to be Bismuth Telluride.
Bismuth-209, which was believed to be the only 'stable' isotope of this element - and was also once thought to be the heaviest stable isotope that exists in nature . . however, this turns out to be not true. We now know that all Bismuth is radioactive to some degree - and the metastable 209 does decay via alpha emission to thallium-205 with 3 MeV energy. This decay was not easy to measure because it is the longest half-life yet found. http://physicsworld.com/cws/article/news/17319 Even so, this does not mean that the decay rate cannot be massively accelerated, given the implications of the Reifenschweiler effect. Metastable is metastable. Bottom line: Bismuth Telluride along with a spillover catalyst - and any mechanism for accelerating the decay rate, could be a most excellent fuel for a combined ZPE/Decay modality (ZPED) since both elements offer a route for nuclear gain.
