Intense deuterium nuclear fusion of pycnodeuterium-lumps coagulated locally within highly deuterated atom clusters

Embedded nano-Pd particles of 5 nm in size instantly absorb abundant D-atoms more than 250% in the atomic ratio against Pd-atoms at room temperature when they are kept in D-2 gas pressurized to less than 10 atm. In such ultrahigh densities, 2-4 D-atoms can be coagulated inside each octahedral space of Pd lattice (pycnodeuterium-lump). When a stimulation energy such as latticequake causing by ultrasonic wave was supplied to these highly deuterated Pd particles, intense deuterium nuclear fusion ("solid fusion") was generated there and both excess heat and 4 He gas were abundantly produced. Naturally, these facts can not be realized at all in bulk Pd. The results show that the nuclear fusion occurs without any hazardous rays in pycnodeuterium-lumps coagulated locally inside the each cell of the host metal lattice. These unit cells correspond to minimum unit of the solid fusion reactor as a "Lattice Reactor".
