In Oct. 2013, Toyota published a paper in the peer-reviewed Japanese Journal of Applied Physics which confirmed important experimental results that Mitsubishi Heavy Industries had first published in 2002. MHI had claimed transmutation of Cesium into Praseodymium via the forced diffusion of Deuterium gas through a thin-film heterostructure containing elemental Palladium using a permeation method pioneered by Mitsubishi; it is capable of triggering nuclear reactions in condensed matter systems under modest temperatures and pressures. Importantly, all of this experimental data is predicted and fully explained by the peer-reviewed Widom-Larsen theory of low energy nuclear reactions (LENRs). While the Mitsubishi permeation...
