| The electrochemically active elements of the transition series include both the third, fourth and fifth d block elements, the lanthanides and the actinides. These transition elements have distinct electrochemistry for driving many chemical reactions, in particular the absorption of large volumes of hydrogen and the formation of various hydrides. In particular, Pd, Th, Ti, Ag, Au and La hydrides exhibit anomalous effects. The chemical reactions for forming, decomposing and rearranging the bonds of metal hydrides involve large energies. Furthermore these metal hydrides and mixtures are here demonstrated to exhibit greater strange cold nuclear reactions both cold fission and cold fusion. This invention provides magnetic, x-ray, laser irradiation, pressure, neutron beam, beta ray, alpha ray, gamma ray and catalytic technology for accommodating the special conditions for more controlled and accelerated cold nuclear reactions within the dense plasma (pycno) provided by the lattice of these metal hydrides. Under these conditions, the cold nuclear reactions are controllably enhanced to rates for practical energy sources but the very nonsynergistic nature of these pycnonuclear phenomena diminishes the possibility of runaway or explosive systems. | ||||||

| 29 | Method and apparatus for improving the energy efficiency for separating the elements in a complex substance such as radioactive waste with a large volume plasma processor | US840967 | 1997-04-21 | US5868909A | 1999-02-09 | Bernard John Eastlund |
| This invention provides methods and apparatus for continuously and efficiently separating the elements in a complex substance such as radioactive waste with a large volume plasma processor. One principal methods utilizes plasma confinement by toroidal magnetic fields with a poloidal divertor magnetic field and converts the plasma from a process plasma to a product plasma at a rapid rate permitting injection of a series of pellets, droplets or streams while the toroidal current in the plasma is maintained. A second principle method involves reducing the radiation losses in the separation process by eliminating the toroidal section and directly converting the feedstock material to a product plasma in an elongated evacuated container surrounded by magnetic field generating coils which produce magnetic fields that are parallel to the long axis of the evacuated container,The apparatus is a large volume plasma processor with multiple containment vessels. The invention provides for the characterization of waste material, and for its separation all within one self contained vacuum environment. Other applications include remediation of chemical toxic wastes and chemical and germ warfare weapons. | ||||||
