METHOD AND DEVICE FOR FORMING NUCLEAR REACTION OR NUCLEAR FUSION -- JPH03138598
Abstract -- PURPOSE: To eliminate a radioactive product and to generate an economically sufficient energy by using an amorphous polymer containing deuterium D2 O as a nuclear fusion medium. CONSTITUTION: Since a nuclear fusion medium using silicon containing D2 O and polyaminoacid has a high ratio of hydrogen bridge connection with a double, multiple minimum potential and adjusts the degree of polymerization to maximize phonon disturbance with a nuclear spin polarization that is tuned finely to obtain a wide tunnel entry path. Also, a nuclear fusion material optimizes connection conditions of D2 O atom to He atom by integrating D2 O atom crystal lattice with a high density. Then, by selecting the tunnel natural frequency of a medium for the incidence frequency of electromagnetic waves, the repulsion force of protons within D2 O atom decreases, thus easily making connection to He atom. These reactions are performance by arranging a container 1 and an electrode 2 coaxially and concentrically and supplying electromagnetic waves from an HF generator 4 to a nuclear fusion medium 3 being introduced between them, and a nuclear fusion product is taken out from a current circuit 5 directly in the form of an electrical energy.
