Title: Collision type nuclear fusion device
Inventor: NAGANO HIROSHI
IPC: G21B3/00
Filed: 2022-02-22
Abstract: To solve such problems that, since a proton exists in a nucleon of a hydrogen isotope (e.g. deuterium), isotopes cannot be fused into one with the repulsive force, a trial of increasing the temperature around the nucleon has not succeeded yet in order to facilitate fusion, and also, the sunlight that is considered to be generated following the fusion has not been observed.SOLUTION: When hydrogen isotopes are made to collide with each other at a relative speed (light speed c/3), the hydrogen isotopes do not recognize a proton of the counterpart, namely the force between the hydrogen isotopes can be kept zero. When a speed condition (c/3) cannot be kept after contacting the counterpart, the intense coulomb repulsive force acts to flick off the counterpart. At this time, a photon such as sunlight should be released and is recovered to be used as a heat source.SELECTED DRAWING: Figure 4-1
