Title: Nuclear fusion power by hypervelocity bullet collision
Inventor: CHUN HONG SUG
IPC: G21B1/00
Filed: 2012-07-20
Abstract: The present invention relates to super-high speed bullet collision type nuclear fusion power generation which absorbs large amounts of heavy hydrogen and tritium or makes a bullet using metal filled with high density and shoots the bullet using a gun capable of shooting the bullet at high speeds and crashes bullets or the bullet to an object. Therefore, the super-high speed bullet collision type nuclear fusion power generation provokes a nuclear fusion reaction of the heavy hydrogen and tritium. One side of a hydride state can absorb the tritium and the other side can absorb the heavy hydrogen or the tritium and the heavy hydrogen can be absorbed because the bullets are crashed or the bullet is crashed to the object. Hydride metal can include the tritium and the heavy hydrogen as a capsule or metal can include the tritium and the heavy hydrogen as the capsule. The bullet can include nuclear fusion fuel with high density. It doesn't have to be metal. The object can be made of a hard object material. The fuel of high density is compressed in a small space in a moment through a high speed collision, and then a nuclear fusion reaction is generated after high pressure is generated. Residual fuel performs a nuclear fusion reaction with energy of the nuclear fusion reaction. Large amounts of neutron are generated at this time and coolant of a blanket which surrounds a reactor is heated. The coolant operates a vapor turbine generator by heating water after passing through a heat exchanger. Lithium reacts to the neutron and produces tritium in the blanket.
